GPU Design comparison between Intel/AMD/Nvidia

[siliconbruh999]

I wanted to make this post since all three members of the RGB Team are making GPU using N5/N4 TSMC Process.

Intel Arc B580:
Process: N5
Die Size: 272mm2 N5(TSMC says N4 is a 6% optical shrink vs N5 so it would be roughly 256mm2 N4)
Xtor Count: 19.6B
Density: 72.1 MTr/mm2
Relative Performance: 100% (1080P games)
Perf Per xtor: 5.10^10-9

AMD 9060XT(NAVI 44):
Process: N4P
Die Size: 199mm2
Xtor Count: 29.7B
Denisty: 149.2 MTr/mm2
Relative Performance: 128% (1080P games)
Perf Per xtor: 4.30^10-9

Nvidia RTX 5060Ti (GB206):
Process: 4N Custom
Die Size: 181mm2
Xtor Count: 21.9B
Density: 121.0 MTr/mm2
Relative Performance: 137% (1080P games)
Perf Per xtor: 6.25^10-9

Intel seems like prefer high performance over high density.

Good summary, here's some SRAM/cache info per GPU as SRAM density is different than logic:

ARC B580
L1: 5MB*
L2: 18MB

9060XT
L1: 1MB**
L2: 4MB
L3: 32MB

5060TI
L1: 4.5MB
L2: 32MB

* 256KB*20 EUs
** 32KB*32 CUs

EDIT: Ugh, table function appears broken.. Maybe user error.

4K Scaling, also from Techpowerup:

ARC B580 - 100%
9060XT - 122%
5060Ti - 130%

ARC a bit stronger at higher resolution but not too much..

Intel Xtor density is only half of AMD.
It's not a good engineering product.

The AI performance is commendable for Arc but yes their xtor density sucks vs competition if they would have been able to take it to Nvidia level density it would be pretty good but maybe next generation

Much has been said about Arc and Xe transistor density compared to AMD and Nvidia, but I never got a really good sense of if the chip size truly is so massively detrimental to product margins.

For instance, is a Xe3 Arc Celestial GPU which has, let’s say 20% better density than Xe2 Battlemage, going to hit Tan’s new mandate of 50% gross margin? Would TSMC N4 vs Intel 18A make a big difference?

Let's get details.
Perf Per xtor benchmark is not important.
What's important is Perf/area.
I have a table as following,
I assume N4p and N4E cost 5% higher than N5.(sorry, it should Perf/cost)

I don't think Intel can compete with cost in double.

well N5 -> N4 is a 6% shrink so the area would be around 256mm2 roughy on scaling it by that factor but i pretty much agree with you for BattleMage for cost i think they would charge around 10-15% more for N4P as it is clear 11% better in PPW and 6% denser than N5.

Intel 18AP will help foundry with volume that's it its a product issue not fab issue and a classic issue of Intel design preferring High performance as for celestial it's not out yet to give a remark and Xe2 vs Xe3 is a big architectural change tbf they may be adding more features to the arch.
