Raja showed a wafer of Arc Alchemist chips at Intel Architecture Day. By snagging a snapshot of the video and zooming in on the wafer, the various chips on the wafer are reasonably clear. We've drawn lines to show how large the chips are, and based on our calculations; it looks like the larger Arc die will be around 24x16.5mm (~396mm^2), give or take 5–10% in each dimension. We counted the dies on the wafer as well, and there appear to be 144 whole dies, which would also correlate to a die size of around 396mm^2.
That's not a massive GPU — Nvidia's GA102, for example, measures 628mm^2 and AMD's Navi 21 measures 520mm^2 — but it's also not small at all. AMD's Navi 22 measures 335mm^2, and Nvidia's GA104 is 393mm^2, so Xe HPG would be larger than AMD's chip and similar in size to the GA104 — but made on a smaller manufacturing process. Still, putting it bluntly: Size matters.
This may be Intel's first read dedicated GPU since the i740 back in the late 90s, but it has made many integrated solutions over the years, and it has spent the past several years building a bigger dedicated GPU team. Die size alone doesn't determine performance, but it gives a good indication of how much stuff can be crammed into a design. A chip that's around 400mm^2 in size suggests Intel intends to be competitive with at least the RTX 3070 and RX 6800, which is likely higher than some were expecting.
