I can’t even make sense of this. Wtf is it supposed to mean?
Ye I’m trying to make sense why it’s stomping on everything in fire strike and losing to 3080 in timespy.
Time spy has massively more vertices, triangles, pixel shader invocations and tesselation. It’s also a pretty full featured dx12 renderer. My guess would be 3080 compute advantage is shining here and in fire strike being pretty old amd comes way ahead with a fillrate advantage.

Yeah Timespy is more compute intensive but AFAIK it lacks some features found in later versions of DX12 ike Async shading, VRS, and so on (I could be wrong on this but I remember some discussion about this in another forum). I think actual game benchmarks are the only way to have a proper comparison between the cards.

Does ES stand for engineering sample? And if so could it not be running at final clocks?
Obviously, but why is 3070 losing to 2080TI in timespy and winning in firestrike?
3070 has less SMs but more fp32 potential. It has less bandwidth and also less TMUs. It has more ROPs.
Could be bandwidth or tmu limited in time spy but pulling ahead with fillrate in firestrike. Also I think 3070 probably has fewer raster units so it may be a geometry bottleneck in time spy.

Pages 22/23 and the following breakdowns might help with data on vertex/triangles/compute per frame in Fire Strike and Time Spy. Also: „Time Spy uses DirectX 12 feature level 11_0. This lets Time Spy leverage the most significant performance benefits of the DirectX 12 API while ensuring wide compatibility with DirectX 11 hardware through DirectX 12 drivers.“
Ah great. So basically useless.
3 weeks seems a bit long historically, at least to my recollections.
Event Oct 28, cards received Oct 30/31, review NDA lifts on Nov 3-5.
Seeing the issues with Nvidia's launch and shipping delays/mixups, I would expect an extra week at the most or Nov 9-11.
You can clearly see on the board pic that it has a 256-bit bus.
