NVidea changed the ALUs ( Calculator circuit ) on the RTX 3080 Serie compared to the RTX 2080 Ti Serie and cards before. SkierEvans wrote: but am confused as to how Resolve compares with CUDA for NVIDIA or OpenCL for AMD. depending on the workload, the application distributes to the graphics card. An SM of Ampere, on the other hand, either 128 FP32 or 64 FP32 and 64 INT32 calculations There are still 64 pure FP32-ALUs per SM, but instead of the 64 pure INT32-ALUs, there are now 64 new ALUs, which can perform floating point and integer calculations.Ī Turing SM can therefore perform a maximum of 64 FP32 and 64 INT32 calculations at the same time. nVidea changed the ALUs on Ampere compared to Turing. So I will be surprised, if the A6000 Ampere will get 656 Tensor Cores?Ībout the 40 TFLOPs of Compute horsepower on Ampere. The NVIDIA GA102 die have 336 Tensor Cores, and the NVIDIA GA100 die for datacenters 512 Tensor Cores. The Quadro RTX A6000 operates at a boost clock of 1860 MHz which should equal around 40 TFLOPs of Compute horsepower.' This is the full-fat Ampere GA102 GPU we are looking at which should be faster than the GeForce RTX 3090 since it packs 2% more cores however it would mostly depend on the clock speeds the card runs at. The specifications list down 10752 CUDA Cores which are arranged in 84 SMs. Quote above link: 'NVIDIA Quadro RTX (Ampere) A6000 Rumored Specifications SylvestCorp wrote:From a leak the nvidia rtx a6000 has 2x the tensor cores. So the technology 8n was not efficient enough to offset the amount of transistors at that performance. Regards Carsten.Each transistor uses fewer watt, but there are many more. I think that nVidea, this time have increased the power consumption, far more than they did for the previous Pascal or Turing Graphics Cards. Here is a Google translate of the link to English:Īnd if somebody prefer, to read the link in German: They decreeased the power consumption from 320 Watt to 270 watt.Īs you can see, did the performance of the RTX 3080 only decrease 4,2%. Here is a link, where they decreased the power consumption for the RTX 3080, to the same level as a RTX 2080 Ti. It's the same silicon as the 3080 (and also the same drivers), it uses around 10% more power and is around 10% faster.Įven so, 10% more performance for 10% more power consumption is much better power/perf scaling than normal in this industry.
