Intel Arc B580 Battlemage GPU specs leaked in accidental retailer listing — Arc B580 features PCIe 5.0 x8 interface, 12GB GDDR6, and 192-bit memory interface

Somebody accidentally activated the listings for Intel's next-gen GPUs before they launched.

Two listings for the next-generation Intel Arc B580 (codenamed Battlemage) GPUs, which will compete against the best graphics cards, have been accidentally posted on Amazon, revealing some specifications. Fortunately, Videocardz and Hardwareluxx grabbed the pertinent information before Amazon removed the listings.

The Intel Arc B580 will be the first desktop GPU to use the Intel Xe2-HPG architecture. While we first saw this architecture in Lunar Lake chips as integrated graphics, we expect the performance of the desktop GPU to be far greater.

Assuming that the renders are accurate, the Arc B580 appears to feature a PCIe 5.0 x8 interface. The listing also said that it has 12GB of GDDR6 graphics memory with a bus width of 192 bits, plus a clock speed of 2,800 MHz.

The two graphics cards that made the brief early appearance are the ASRock Arc B580 Steel Legend, which has a white theme and features three cooling fans with RGB. There’s also a smaller ASRock Arc B580 Challenger, which only has two fans and reportedly only hits 2,740 MHz.

Another difference in the images of these two GPUs is their power supplies—the larger Steel Legend uses two 8-pin connectors, while the smaller Challenger has a single 8-pin connector for additional power. On the other hand, both graphics cards show three DisplayPort and one HDMI port for video output; we don’t have any details on what standards these ports use, though.

Intel has been mum on when it’ll launch its next-generation Battlemage GPUs, but we’ve seen several clues that point to an imminent launch. For example, retail boxes for the Intel Battlemage B580 have appeared in shipping manifests, while several leakers have pointed to a December launch for the Xe2 Battlemage GPU. We’ve even seen leaked Benchmark results purported to come from a Battlemage graphics card a few months back.

If Team Blue does launch its next-generation GPU in December, it’ll arrive a few weeks before the much-anticipated launch of Nvidia’s RTX 50-series GPU and even AMD’s RDNA4 GPU. Because of this, we expect to head into the new year with a bevy of new GPUs from the big three chip makers.

    I don't believe the listings featured PCIe revision this was just a guess. The images do appear to show an 8 lane interface. When comparing this to the A580 it's a loss of about 56GB/s in bandwidth (I doubt the A580 needed that much in the first place) but around 35% higher GPU boost clock speed. Rumored specs and leaked tests indicate the B580 has 20 EUs which would be 4 fewer than the A580.

    Hopefully these popping up now is more of a sign that Intel wants to get a jump on the market rather than them shoving these out the door to just be early.

    Can't wait for Battlemage. Alchemist being their first series felt like it needed time to mature - including drivers. That gives Battlemage a headstart. If they're priced as well as Alchemist was, I think they'll be a good competitor to lower-cost AMD and Nvidia cards.

    Does anyone have any guesstimates how it will perform aginst the A770?

    If it clocks 20% higher, with 50% better compute units, but 2/3 of them, then it would be around 20% faster than the A770. I made these up but the clock is definitely faster and Battlemage is found in Lunar Lake.

    I'm assuming a B580 would be near the A750. Unlikely to be as high as the A770 but maybe with updated drivers it could be. That being said, the difference between Ryzen 1st Gen and 2nd was quite a bit so maybe it's possible for Intel too.

    If the B580 isn't faster than the A770 then quite frankly Intel's discrete graphics future is in trouble. The A770 still swings from slower than a RX 6600 to faster than a 3060 Ti depending on the title which is a pretty massive performance swing. The Battlemage architecture will hopefully have resolved some of those outliers along with being more performant in general. That combined with higher GPU boost clock speeds (B580 leaks are 16-17% higher than the A770) really need to put it on average above the A770 even if it can't match the highs.

    It's 8 lanes but PCIe 5 rather than 4 so it's not slower in that regard.

    PCIe 5.0 still isn't confirmed it's just a guess based on the connector design. The new design doesn't guarantee PCIe 5.0 anymore than the prior one did that it would be limited to 4.0 (the MTT S80 is PCIe 5.0). It likely is PCIe 5.0, but until the interface is confirmed it's just a guess.

    I'd be surprised if the PCIe bandwidth mattered much on this part, but perhaps on a PCIe 3.0 platform it would (if it works without ReBar).

    12GB of VRAM doesn't seem like a good target to aim for these days. I seem to remember Intel's previous gen stated it required ReBar and had abysmal performance if it didn't get it.
