Don't the console APIs and Apple's Metal already make use of an APU/SoC's advantages? And on the PC side, I doubt developers would be interesting in using a new API just to squeeze more performance out of APUs.
DX12, DX12U, DXR, API bias, and API evolution ..

Why would this need a new API? There are already functions in DX12 that allow discrete GPU based systems to behave a little like APU's (the ability to read and write to both memory pools for example). Having a separate API just for APUs would be totally unusable.

sorry I am but a humble compiler dev, i don't know the ins and outs of gpu api's except for some opengl stuff that I learned back in collage as a elective 10 years ago.
In the new UL benchmark Normad Vulkan is up to 11% faster on nVidia than DX12: https://www.computerbase.de/2024-05..._directx_12_vs_vulkan_mit_geforce_radeon__arc

PCGH presented the results with the best scores. Here are the 4K max results:
4090: 103 fps
4080S: 72 fps
7900XTX: 66 fps
3090Ti: 60 fps
6950XT: 43 fps
2070S: 24 fps
5700XT: 21 FPS
3DMark Steel Nomad im Test mit 40 Grafikkarten: Neuer Benchmark mit einigen Überraschungen
Steel Nomad im Benchmark mit 40 Grafikkarten
That would be nice but I would be very surprised. 3dmark has been playing catch up for a long time now and it’s tech isn’t up to par with the best engines. I’m just hoping this one at least looks good.
It's out now and I gave it a run. It's about 5% faster in Vulkan vs DX12 on my 3090. Explorer mode is a nice addition.
It looks like a solid UE4 implementation but doesn't really push the envelope or do anything we haven't seen before. Lots of screen space stuff that defined last generation. Environment detail is pretty good. I don't understand why UL is unable to generate more impressive graphics in these very constrained demos when full fledged games can do better. It's like they're 4-5 years behind the cutting edge which kind of makes their benchmarks pointless. 3dmark had its heyday when it was 4-5 years ahead of the best games could offer.
A few things immediately stood out to me.
- No contact hardening or soft shadows
- Stiff cloth physics
- Unconvincing materials, especially on the armor and clothes of the soldiers

Wait what, UE4?
Yeah I meant UE4's feature set. 3dmark is running on its own custom engine as usual.
I wonder how much of the feature deficiency is because they wanted a "singular" benchmark that can run on desktop and mobile (making the results a bit more comparable).
Don’t really need special hardware for better material shading or soft shadows though. I think they could’ve made the benchmark a bit heavier especially since it’s so constrained in scope. A 4060 Ti already gets over 30fps so in a generation or two mainstream cards will breeze through it.

This is their more general benchmark, Speedway is still their premier one
Not sure about that. They seem to be positioning this as their premier non-RT benchmark.

I’m power limited on a stock 4090, about halfway between base and boost clocks.
Here's a blogpost which vindicates that PSOs were the correct performance abstraction all long. The truth was that PSOs allowed drivers to do dead code elimination and cross-stage/inlining optimizations all along ...
