Correct me if I’m wrong here, but is the 395 not leagues ahead of something like a 4090 when it comes to performance per watt? Here’s a comparison graph of a 4090 against the Radeon 8060S, which is the 395’s iGPU:
Now that’s apparently running at the 395’s default TDP of 55W so that includes the CPU power. It’s also clear that a 4090 can trounce it on sheer performance when needed. But if we take a look at this next graph:
This shows that a 4090 has a third of the performance while still running at 130W, more than twice the TDP of the entire 395 APU.
Edit: This was buried in the comments under that second graph but here’s the points scored per Watt on that benchmark: 130W = 66 / 180W = 85 / 220W = 92 / 270W = 84 / 330W = 74 / 420W = 59 / 460W = 55
and this clearly shows the sweet spot for a 4090 is 220W.
You can boost the 395 up to 120W, which might be where Framework is pushing it too, but those benchmarks are labelled 55W and that’s what AMD says is the default clock without adjustment. I’d love to see how the benchmarks compare at that higher boost but I’d imagine it’s diminishing returns similar to most GPUs. I think the benefit to using it in a lounge gaming PC would be the super low power draw, but you would need to figure out a display MUX switch and I don’t think that’s simple with desktop cards. Maybe something with a 5090 mobile would be the go at that point, but I have no idea how that compares to the 395 and whether it’s worth it.
