Nvidia Ampere Discussion [2020-05-14]

The "new" cooler seems to be very effective. Hope some review really test the claims.

A decent set of AAA games was also run on the purported RTX 3080 system and yielded the following RTX 2080 Super comparisons:

  • Farcry 5 - 4K, GPU maxed at 99% (throttling), 5GB Video Memory used, 62% faster than 2080S
  • Borderlands 3 - 4K, DX12, GPU maxed at 100% (throttling), 7.4GB Video Memory used, 56% faster than 2080S
  • Horizon Zero Dawn - 4K, GPU maxed at 99% (throttling), 9.9G Video Memory used, 76FPS average
  • Assasins Creed Odyssey - 4K, GPU at 97%, 7GB Video mem, 67fps average, 48% faster than 2080S
  • Forza Horizon 4 - 4K, 143fps, GPU at 97%, 48% faster than 2080S

I'm not sure what they mean by "throttling" though.
I'm sure it's about power throttling when GPU get's 1V+ on die.
With more efficient use of resources, power usage get's higher.
Fully unlocked high end Turings (TU104/TU102), are always power limited under most GPU heavy scenarios (assuming not CPU/platform limited).

NV should learn how to lock default max. boost voltage to be around 0,9V.
Otherwise, they will only make even bigger heater next time.
Default max. doesn't have to be maximum allowed under OC.
 
It's the same benchmark which was making the rounds yesterday.
The heavier is the workload on shading - the higher is the gain over 20 series.
I'm not sure what they mean by "throttling" though.

What it means is the clock drops because of power or heat constraints.

Again, which is a normal mode of GPU boost operation.

There's thermal throttling which happens if the card hits above max temp but I doubt that these FEs will throttle like this. If they will then these weird looking new coolers on them are actually bad.
 
It's not "throttling", it's normal GPU boost operation.
Throttling or limit, doesn't matter how you name it.
GPU Boost works from limit to limit because it's not meant for GPU to have stable performance.
Meaning : Theoretical value at set clock speed are 100% inaccurate for trying to make/calculate a end performance value.
Still, everything is fine... as long, as you don't compare performance with clock speeds of those type of cards.
