Amazon listings for Battlemage GPUs temporarily appeared on the eCommerce platform, revealing some specifications for Intel's next-generation GPUs.

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.

 

[Mindstab Thrull]

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.
