Intel at the 2025 Computex unveiled its Arc Pro "Battlemage" line of graphics cards powered by its latest Xe2 graphics architecture, and based on its 5 nm BMG-G21 silicon. The Arc Pro B50 is targeted squarely for professional visualization and graphics workstations; and comes with 12 GB of memory. The Arc Pro B60, on the other hand, has 24 GB of memory and has additional use-cases in the area of AI inferencing. Unlike AMD and NVIDIA, Intel is going to market for its Arc Pro B-series with board partner-based custom designs. These partners include ASRock, Gunnir, Maxsun, Sparkle, Onix, Senao, and Lanner.

As a pro-vis solution, the Arc Pro B50 series comes with a comprehensive set of certifications and validation by leading content creation applications. Intel is working on bolstering its AI inferencing product stack, with the debut of the new Project Battlematrix Linux software stack, and workstation platform, which enables up to 8 Arc Pro GPUs with 192 GB of memory between them, for accelerating 70 billion+ parameter models.

Maxsun's parent company has quietly registered new 24 GB versions of Intel's Arc B580 graphics card with the EEC. While regulatory filings often cover placeholder or speculative hardware, this submission lines up with ongoing rumors about a high-memory "Battlemage" model aimed at both gamers and professionals. Back in December and January, Intel launched the Arc B580 and B570 GPUs, bringing the Battlemage architecture to desktops just a few months after "Lunar Lake" appeared on laptops. Those first cards came with 12 GB of GDDR6 memory, a surprisingly generous amount for graphics cards selling under $300, and they helped establish Intel as a real contender in the mainstream GPU market. Since then, chatter about a 24 GB version has never died down. The story gained weight when board partner Sparkle briefly hinted at such a variant and then retracted the comment under NDA obligations. Further fueling speculation, a Sparkle representative in China discussed the planned "B580 24 GB" during a March social-media exchange.

Now, Maxsun's EEC filing lists two models called "iCraft 24G" and "iCraft 24G OC," and those names match what Sparkle first mentioned. There's no guarantee these cards will actually hit store shelves, but the matching details and timing suggest Intel may be testing the waters for a memory-heavy Arc B580. That would make sense given recent leaks about an Arc PRO A60 workstation card also packing 24 GB of memory. Under the hood, the Arc B580's BMG-G21 chip offers up to 20 Xe cores and 2,560 shader units, putting it in the same ballpark as NVIDIA's GeForce RTX 4060. With Computex just days away, Intel will finally reveal whether these high-memory Arc B580 cards, or perhaps even bigger Battlemage-based workstation GPUs, are coming our way. Additionally, enthusiasts are keeping an eye on the rumored Arc B770, which is expected next quarter and likely to be detailed at Computex alongside Intel's broader Battlemage and upcoming Xe3 "Celestial" roadmap.

Earlier in the week, reports indicated the potential introduction of an Intel Xe2 "Battlemage" B770 gaming graphics card at Computex 2025. Last night, a Team Blue tweet confirmed forthcoming product unveilings: "new Intel Arc Pro GPUs are on the way. See you in Taipei!" In the months leading up to this important trade event, industry watchdogs have drummed up speculation about "Battlemage's" future (or fate). Whispers of 24 GB VRAM-equipped variants emerged late last year—around late January, these theories were connected to an official leak: "3 new PCI IDs for BMG."

Unsurprisingly, VideoCardz has weighed in with some new inside track info—they propose that one of Intel's upcoming professional options will be an "Arc Pro B60 24 GB" model, aka "Developer Edition" (an alleged in-house reference). Despite Sparkle HQ downplaying recent "rogue claims," a company rep (in China) alluded to a possible May/June release of their own custom 24 GB "Battlemage" productivity-oriented card. VideoCardz has picked up on rumors, regarding the "Arc Pro B60's" internal setup. They propose Team Blue's selection of the familiar "BMG-G21" GPU; as used by their Arc Xe2 B580 12 GB and B570 10 GB designs. According to an unnamed inside source, this professional/workstation variant will stick with the usual 192-bit memory interface. Intel's Computex 2025 new product teaser provided a big clue about the speculated "B60" model's cooling solution.

Intel appears ready to broaden its Arc "Battlemage" lineup with a new, more powerful desktop graphics card likely to be called the Arc B770, potentially arriving as soon as next quarter. Until now, Team Blue has introduced only two Xe2 Battlemage models, the B570 (10 GB) and B580 (12 GB), both of which earned praise for solid performance at accessible price points. Enthusiasts have long speculated about successors like the B750, B770, and even a B780, but Intel shifted its public focus to upcoming AI PC processors after the B570 launch, leaving GPU fans uncertain which designs would materialize. Recent shipping manifests uncovered a "BMG‑G31" GPU die en route to Intel's Vietnam assembly plant, the same site that produced limited‑edition B570 and B580 cards, while insider Haze2K1's documents hint at a "B7XX" special‑edition series. Simultaneously, chatter about a 24 GB Developer Edition based on the earlier BMG‑G21 die suggests Intel is also eyeing workstation and creative‑professional markets.

A well-known tipster, OneRaichu, has further fueled excitement by reporting that the Arc B770 could pack between 24 and 32 Xe2 compute units, a 256‑bit memory interface, and 16 GB of GDDR6, positioning it squarely against rival xx60‑series models and promising a meaningful boost in gaming and compute workloads. Beyond Battlemage, Intel's next‑generation graphics architecture, Xe3 "Celestial," has reached pre‑silicon validation. According to Intel engineer Tom Petersen and corroborating industry leaks, Celestial's core media engines, Xe cores, XMX matrix units, and ray‑tracing hardware are fully designed and are now being tested in a hardware model to fine‑tune power consumption and clock speeds. With Computex 2025 kicking off in late May, Intel may at last clarify both its high‑end Battlemage refresh and the broader Celestial roadmap, potentially reshaping competition in the mainstream and next‑generation GPU markets.

VideoCardz has put a spotlight on a compelling Intel Community announcement—ten days ago, a site moderator (RonaldM_Intel) disclosed that company engineers are currently engaged in the investigation of a major Arc graphics card-related issue. At the beginning of 2025, Hardware Unboxed uploaded a video article (see below) that delved into the Arc Xe2 B580 graphics card design's "big problem." Going back several months, review outlets observed B580 sample cards leveraging lower than expected performance when paired with older generation processors. As summarized by VideoCardz's recent report; significant performance drops were tracked when test units were linked up with AMD Ryzen 5 2600 or 5600 CPUs—relative to a more modern rig; powered by Team Red's Ryzen 7 9800X3D. Additionally, evaluators observed worrying signs when B580 cards were tested on platforms based on Intel's 9th Gen Core i5-9600K processor.

Budget-conscious buyers have embraced Team Blue's new generation cards, with many participants upgrading older builds with Intel Arc B580 12 GB and B570 10 GB graphics cards (original launch MSRPs: $250 and $220, respectively). Given that many owners will be sticking with prior-gen processors, industry watchdogs have leveled criticism at Team Blue—the company has disappointed many, with an apparent lack of action. Months after the fact—likely after a healthy intake of community feedback—Intel has officially acknowledged these issues. As disclosed by RonaldM_Intel's announcement: "thank you for your patience. We are aware of reports of performance sensitivity in some games when paired with older generation processors. We have increased our platform coverage to include more configurations in our validation process, and we are continuing to investigate optimizations."

At the tail end of March, an interaction between Tomasz Gawroński (aka GawroskiT) and Jaykihn (jaykihn0) indicated that Intel had abandoned the development of higher-end Arc Xe2 "Battlemage" graphics cards—possibly back in late 2024. Months of silence—since the launch of pleasingly wallet-friendly B580 and B570 models—instilled a sense of unease within segments of the PC gaming hardware community. Many watchdogs assumed that company engineers had simply moved onto devising futuristic Arc Xe3 "Celestial" equivalents. As discovered last week, hopes have been elevated for a potential expansion of Team Blue's "Battlemage" dGPU lineup. Haze2K1 highlighted an intriguing entry within an NBD shipping manifest; a "BMG-G31"-type GPU was transferred "for R&D purposes." Currently, the lower end of Intel's B-card series is populated by discrete solutions based on their smaller "BMG-G21" GPU design.

Tomasz Gawroński spent part of his Easter weekend poring over shipping documents; soon stumbling on an entry that mentioned a mysterious "IBC C32 SKT"—again, listed under "research and development" purposes. In a reply to Gawroński's social media bulletin, miktdt weighed in with a logical theory: "because of the BMG in the text the best I could believe is a reworked/restarted BMG G31. C32 could simply mean cores 32 which is a fully-enabled G31. This makes more sense to me." VideoCardz posits that these leaks do not necessarily signal the revival of fortunes for more potent Arc Xe2 "Battlemage" SKUs; Intel could be shipping "canceled project" prototypes to different locations. Going back to late summer 2023, a "BMG G10" GPU die was spotted by members of the press during a tour of Team Blue's Malaysian test lab. Back then, certain industry insiders believed that the whole "Battlemage" endeavor was going through "development hell." Fast-forward to the present day; OneRaichu reckons that there is still a likelihood of Team Blue's "B770" model turning up at some point in the future.

A recent job listing at Intel for a memory sub-system validation engineer—a person that tests and validates memory with new types with prototype silicon, suggests that Intel is implementing the contemporary GDDR7 memory standard with an upcoming GPU. The position calls for drive-and-deliver pre- and post-silicon validation and characterization of GDDR6 and GDDR7 memory types on Intel's Arc GPU products. Given that Intel is putting this listing out now, in Q2-2025, an actual product that implements GDDR7 could be rather far out, considering typical GPU silicon development timelines. We predict such a chip could be taped out only by 2026, if not later.

A possible-2026 tapeout of a GPU silicon implementing GDDR7 points to the likelihood of this being a 3rd Gen Arc GPU based on the Xe3 "Celestial" graphics architecture. Given Intel's initial success with the Arc B580 and B570, the company could look to ramp up production of the two through 2025, and continue to press home its advantage of selling well-priced 1080p-class GPUs. Intel could stay away from vanity projects such as trying to create enthusiast-class GPUs, sticking to what works, and what it could sell in good volumes to grab market share. This is a business decision even AMD seems to have taken with its Radeon RX RDNA 4 generation.

Earlier today, reports pointed to an intriguingly discounted Intel "Battlemage" GPU-based graphics card on the Mindfactory.de webstore—ASRock's Arc B570 Challenger OC 10 GB model was priced at €249. European retailers would normally charge €279 for this specific SKU, but the Germany-headquartered PC hardware retail outlet offered a discount of €30, albeit briefly. VideoCardz noted that the fairly new Arc B570 Challenger OC model has been listed on Mindfactory's site since late last year—following Team Blue's early December unveiling of second wave Battlemage GPUs.

The timing of this special offer is a tad surprising, given that Arc B570-based graphics cards only reached global markets late last week. A compelling discount could have been implemented to entice buyers away from more expensive (€299 MSRP) Arc B580-equipped products, but Team Blue and its board partners have struggled—as-of-late—to keep these items in stock. Budget-minded gamers have seemingly embraced the slightly less potent B570 GPU family, and German customers surely had a great opportunity to save some Euros (over the past day or two). Mindfactory's time-limited sale produced a €50 gulf between the ASRock custom design and Intel's Limited Edition B580 model.

ONIX has quietly added Intel Arc B580 GPU-based models to its Newegg brand store—signalling the brand's arrival on North American's e-tail landscape. TechPowerUp first picked up on this new manufacturer's existence during Team Blue's introduction of Arc B-series "Battlemage" graphics cards—soon followed up with an updated version of TechPowerUp GPU-Z; adding "PCI vendor detection for ONIX." The emerging Chinese manufacturer's Odyssey OC and Lumi OC models are currently "out of stock" on the Newegg store, but compelling pricing ($10 above Intel's baseline MSRP) has attracted press coverage.

It is not clear whether initial supplies of the two ONIX cards were snapped up quickly, but Newegg states on both listings: "this product is temporarily out of stock because of high demand, we will replenish it as soon as possible." Currently, the Arc B580 Odyssey OC 12 GB (black) model is priced at $259.99, while its Lumi OC (white) sibling goes for $269.99—note: Newegg demands a $9.99 fee for shipping. VideoCardz reckons that ONIX is competing closely with Sparkle—a veteran Intel GPU board partner—and charging less than GUNNIR for equivalent specs/fittings. ONIX's official website features a product page for an Odyssey B570 10 GB model—not listed by Newegg, but we expect it to turn up soon. Intel and its AIBs declared B570's retail availability last week.

Intel today released the latest version of the Arc GPU Graphics Drivers. Version 101.6458 WHQL comes with support for the new Arc B570 graphics card the company launched today. The drivers also add support for the Xe-LPG iGPU of Core Ultra 200H series "Arrow Lake-H" mobile processors. For Core Ultra 200-series iGPUs, the drivers add an up to 6.8% performance uplift in "Call of Duty: Black Ops 6." The drivers address an issue with "Indiana Jones and the Great Circle" where the game exhibits inconsistent performance and memory usage. "Shadow of the Tomb Raider" saw an intermittent application crash and display corruption in the game menu with XeSS enabled, which has been fixed. Grab the drivers from the link below.

Intel today formally launched its second graphics card from the Arc "Battlemage" family, the Arc B570. This card is being launched at $220, or $30 cheaper than the Arc B580 from last month. With it, the company is looking to disrupt several products around the $200-mark, and probably even wage price wars below that mark. The card is designed to offer a 1080p AAA gaming experience enhanced with ray tracing, and the XeSS 2 feature set (super resolution, frame generation, and low-latency). Given that there is no RTX 3050 successor from NVIDIA, or anything from AMD around this price point, except older generation RX 6600-series products, the B570 could be poised to grab a chunk of the value-ended gaming PC market share.

The Arc B570 is based on the same 5 nm "BMG-G21" silicon that also powers the B580. It has 18 Xe cores enabled across five Render Slices, giving it 112 EU (execution units), or 2,240 unified shaders. Other key specs include 144 XMX cores for AI acceleration, 18 ray tracing units, 144 TMUs, and 60 ROPs. Perhaps the biggest differentiator between the B570 and B580 is memory, the B570 gets 10 GB of it, over a 160-bit wide GDDR6 memory bus, on which it runs 19 Gbps memory to yield 380 GB/s of memory bandwidth. With a total board power of 150 W compared to the 190 W of the B580, the B570 makes do with a single 8-pin PCIe power connector on even the factory overclocked parts. Intel has set a $220 baseline price, however, there is no reference design card, and the cheapest custom design cards start at $230, with an included factory overclock. We reviewed two such cards today, you can find them in the links below.

Read the TechPowerUp Reviews of the ASRock Arc B570 Challenger OC and the Sparkle Arc B570 Guardian OC.

In the past few weeks, all eyes have on NVIDIA's and AMD's next-gen GPU offerings, and rightly so. Now, it's about time to turn our attention to what appears to be the third major player in the GPU industry - Intel. This is, of course, all thanks to the Blue Camp's wildly successful Arc B580 launch, which propelled the beleaguered chip giant to the favorable side of the GPU price-to-performance line.

Now, it appears that a fresh leak has revealed how its soon-to-be sibling, the Arc B570, is about to perform. The leaked performance data, courtesy of Geekbench OpenCL, reveals that the Arc B570 is right around 11% slower than the Arc B580 in the synthetic OpenCL benchmark, which makes complete sense, because the card is also expected to be around 12% cheaper than its more powerful sibling, as noted by Wccftech. With a score of 86,716, the Arc B570 is well ahead of the RX 7600 XT, which manages around 84000 points, and well behind the RTX 4060, which rakes in just above 100000.

Over the past weekend, an Intel Arc GPU enthusiast has picked up a pair of embargo-busting ASRock Arc B570 Challenger 10 GB OC graphics cards. Intel has mandated an official launch at retail on January 16, yet Redditor genxontech presented photo proof of his two Arc Battlemage purchases and claimed that their local Micro Center store had stock available on shelves. The lucky customer stated that he was not willing to experience post-Thursday shortages or dreaded price gouging over limited supply: "I'm upgrading my son's PC from a GTX 1080 and the other one is for me. I work, I don't need to scalp it."

Team Blue's Arc B580 GPU series (starting price: $249) launched mid-December and retail units were snapped up swiftly—budget-conscious hardware enthusiasts have oft complained about a lack of choice/value within their market segment of choice. The incoming Intel Arc B570 GPU family is priced $30 below the slightly more capable B580, so it will be interesting to see how the two tiers perform against each other in 2025. Meanwhile, genxontech has toyed around with the latest Arc Drivers—official software is not available until this Thursday, so mixed results have been documented: "My workstation/server/gaming rig now sees the Arc B570 as a B80. Crazy, right?"

Intel could be working on a new Arc graphics card according to Quantum Bits quoted by VideoCardz. It's based on the Battlemage architecture and has 24 GB of memory, twice as much as current models. This new card seems to be oriented more towards professionals, not gamers. Intel's Battlemage lineup currently has the Arc B580 model with 12 GB GDDR6 memory and a 192-bit bus. There's also the upcoming B570 with 10 GB and a 160-bit bus. The new 24 GB model will use the same BGM-G21 GPU as the B580, while the increased VRAM version could use higher capacity memory modules or a dual-sided module setup. No further technical details are available at this moment.

Intel looks to be aiming this 24 GB version at professional tasks such as artificial intelligence jobs like Large Language Models (LLMs) and generative AI. The card would be useful in data centers, edge computing, schools, and research, and this makes sense for Intel as they don't have a high-memory GPU for professional productivity markets yet. The company wants to launch this Arc Battlemage with bigger memory in 2025, we guess it might be announced in late spring or ahead of next year's Computex if there's no rush. Intel in the meantime will keep making their current gaming cards too as the latest Arc series was very well received, a big win for Intel after all the struggles. This rumor hints that Intel's expanding its GPU plan rather than letting it fade away, that was a gray scenario before the launch of Battlemage. Now it seems they want to compete in the professional and AI acceleration markets as well.

In addition to the previously unveiled Arc B580 ROC Luna OC Ultra graphics card and low-profile Arc B570 graphics card, it appears that Sparkle will have quite a few other Intel Arc Battlemage graphics cards soon, including an all-white Arc B570 Guardian LUNA and the B580 TITAN Luna graphics card.

Earlier pictured by Videocardz.com, the Arc B580 TITAN Luna is a high-end version with triple-fan design, which swaps the Sparkle's blue design with a white shroud, white PCB and white backplate. The only thing that did not get painted, and it is quite a shame, is the I/O bracket. The Arc B580 TITAN Luna is expected to be pretty much the same as the standard version, featuring a slight factory overclock to 2740 MHz.

In addition to the TITAN and GUARDIAN SKUs announced earlier this month, Sparkle is working on several other SKUs. The roadmap includes the low-profile version of the Arc B570, as well as the Arc B580 ROC OC Ultra, which is expected to come with a 2,800 MHz GPU factory overclock and 210 W TBP, both coming next year.

According to the roadmap, Sparkle plans to release the B580 ROC OC Ultra version in February 2025, and this one will be a part of Sparkle's ROC Luna series, featuring an all-white design. As said, it gets a 2,800 MHz GPU factory-overclock, which is 60 MHz higher than the Sparkle Arc B580 TITAN OC. It also has a slightly higher 210 W TBP. Sparkle included a small picture showing a 2.5-slot thick design with a dual-fan cooler. Additional roadmap also confirms the launch of the Arc B570 Low-Profile version, which will feature a lower 170 W TBP and a three-fan cooler, similar to what we have seen from GUNNIR lately.

Intel's upcoming Arc "Battlemage" graphics card lineup has been exposed through a recent ASRock specification sheet leak, showcasing the company's latest products for the discrete GPU market. The leak details two models, the B580 and B570, with the B570 making a first appearance in the rumor section. The B580, positioned as the flagship model we already covered, features 20 Xe2-Cores and comes equipped with 12 GB of GDDR6 memory on a 192-bit interface, capable of reaching bandwidth speeds of up to 456 GB/s. Its slightly lower-spec sibling, the B570, sports 18 Xe2-Cores and 10 GB of GDDR6 memory on a 160-bit interface, delivering 380 GB/s bandwidth. In ASRock's case, both cards will be factory-overclocked, with the B580 reaching speeds of 2.8 GHz and the B570 hitting 2.6 GHz.

The new graphics cards are designed to operate on a PCIe 4.0 x8 interface. Both models will support modern display standards, including DisplayPort 2.1 and HDMI 2.1. Intel has scheduled the official unveiling of the Battlemage series for December 3, with cards expected to hit shelves on December 12. While the B570's pricing remains under wraps, the B580's rumored $249 price tag suggests Intel is making a serious play for the mid-range market segment. This aggressive pricing strategy, combined with the card's promising specifications, indicates Intel's determination to establish itself as a legitimate mid-range competitor in the discrete GPU segment, which NVIDIA and AMD have long dominated.

According to the latest information from Videocardz, the Intel Arc Battlemage announcement and launch could be closer than expected. The official announcement for two first SKUs, the Arc B580 and the Arc B570, is apparently scheduled for December 3rd, with availability and first reviews coming on December 12th.

Intel is expected to announce and launch two mid-range SKUs, the Arc B580 and the Arc B570, and has yet to give any information on the rest of the lineup, including higher-end as well as entry-level SKUs. The Arc B580 SKU has been leaked recently and is said to feature 20 Xe2-cores with a GPU clock of 2.8 GHz. The board comes with 12 GB of 19 Gbps GDDR6 memory on a 192-bit memory interface and needs two 8-pin power connectors. The price is said to be set at around $250, according to rumors and listings spotted earlier. The second SKU, the Arc B570, is rumored to pack 18 Xe2-cores, while the rest of the information is still unknown.
