Arc B390 vs. Radeon 8060S: Two very different GPUs for the same 14-inch screen size

[Redaktion]

How close does Intel's newest Panther Lake Arc B390 iGPU come to the Strix Halo Radeon 8060S?

The 8060S is able to stay close in efficiency by utilizing several times the die area for the GPU. That's a big part of the reason why it is so rare (and expensive).

[Good question]

It'll be interesting to see how AMD's eventual successor to the Radeon 890M can compare against the super-efficient Panther Lake iGPU series.

Good question, because if Intel is using TSMC' 3N node for its iGPU chiplet and AMD for its APU (which contains the 890M iGPU) is using TSMC 4N, then Intel's power efficiency advantage should only be ~30% (4N to 3N -> 1 node power efficiency advantage), but the B390 is over 60% more power efficient (at a 25W power limit) and this is a 2 nodes advantage.

CP2077: 2560x1440 Ultra Preset (FSR off):
8060S is 71% faster, but power consumption was twice, did you confirm?

Test power efficiency for CP2077 Overdrive preset (yes, the 390B is going to be too weak for this preset). Maybe it could run Overdrive at 720p?

LH, yes, Strix Halo it a big, 256-bit wide, APU. While Panther Lake is 128-bit wide. This's almost half the bandwidth (9600 MT/s (PL) vs 8000 MT/s (SH)).
