The B770 hasn’t even been confirmed to exist yet, and three months post-launch B580 supply/prices doesn’t seem to have meaningfully improved.
I’d love there to be a serious third player as much as the next person… but right now, it feels like the community is just projecting their hopes and dreams onto Intel. There’s no reason to believe they’re gonna drop a B770 that matches the 5080 while costing less while also being produced in such volume as to be unscalpable. It just won’t happen.
Agreed, so this is mostly toward people wishing for B770...
Keep in mind that B580 barely beats the RTX 4060. Yes, it costs less... in theory. But not because it's an amazing GPU and warrants a higher price; Intel can't sell Arc GPUs at higher prices when there are concerns about drivers, features, software, etc. XeSS 1.3.1 looks good, maybe close to DLSS 2. XeSS 2 might look better, but it's only in a few games. It makes FSR3.1 support look amazing.
Based on my tests, to get an Arc B770 close to RTX 5080 performance, Intel would need to more than double the performance of the B580. At 4K ultra, the 5080 is currently 179% faster than the B580. And really, there's no reason to do B770 if it's not targeting higher resolutions with more VRAM. So, based on that, B770 would need:
56 Xe-cores
512-bit memory interface
(Alternatively: 384-bit with GDDR7)
About 43 billion transistors
Die size of about 600 sqmm
525W TGP
Again, that's to match Nvidia's RTX 5080 that uses a chip with a 256-bit memory interface, 45.6 billion transistors, and a 378 sqmm die with a 360W TGP. Intel still doesn't seem to be getting anywhere close to the same levels of performance per transistor or performance per square millimeter of die area as Nvidia, or even AMD.
Battlemage delivered a good improvement over Alchemist, and the original launch pricing made it look very attractive. Right now, B580 costs about $400, compared to RTX 4060 at $350. Yes, you get more VRAM, but at 1440p, in my testing, B580 is only 10% faster — and at 1080p it's a tie. And despite claims that it's a 1440p card, it's really more of a 1080p card, or 1440p in less demanding games that also work fine in the 4060's 8GB VRAM.
B770 with double the performance of the B580 would be nice. But it would probably also need to be closer to 3X the price. $750 for such a card still seems mostly viable, if it were out right now. In six months? Maybe it won't matter as much.
