![]() NVENC HEVC Main10 10bit hardware encoding.HDCP 2.2 support for 4K DRM protected content playback and streaming (Maxwell GM200 and GM204 lack HDCP 2.2 support, GM206 supports HDCP 2.2). ![]() PureVideo Feature Set H hardware video decoding HEVC Main10(10bit), Main12(12bit) and VP9 hardware decoding.Enhanced SLI Interface - SLI interface with higher bandwidth compared to the previous versions.Fourth generation Delta Color Compression.Simultaneous Multi-Projection - generating multiple projections of a single geometry stream, as it enters the SMP engine from upstream shader stages.GDDR5X - new memory standard supporting 10Gbit/s data rates, updated memory controller.Īrchitectural improvements of the GP104 architecture include the following: Instruction-level and thread-level preemption.Nvidia therefore has safely enabled asynchronous compute in Pascal's driver. This allows the scheduler to dynamically adjust the amount of the GPU assigned to multiple tasks, ensuring that the GPU remains saturated with work except when there is no more work that can safely be distributed to distribute. Dynamic load balancing scheduling system.More registers - twice the amount of registers per CUDA core compared to Maxwell.16-bit ( FP16) floating-point operations (colloquially "half precision") can be executed at twice the rate of 32-bit floating-point operations ("single precision") and 64-bit floating-point operations (colloquially "double precision") executed at half the rate of 32-bit floating point operations.Allows much higher transfer speeds than those achievable by using PCI Express estimated to provide between 80 and 200 GB/s. NVLink - a high-bandwidth bus between the CPU and GPU, and between multiple GPUs.Unified memory - a memory architecture, where the CPU and GPU can access both main system memory and memory on the graphics card with the help of a technology called "Page Migration Engine".High Bandwidth Memory 2 - some cards feature 16 GiB HBM2 in four stacks with a total of 4096-bit bus with a memory bandwidth of 720 GB/s.Maxwell packed 128, Kepler 192, Fermi 32 and Tesla only 8 CUDA cores into an SM the GP100 SM is partitioned into two processing blocks, each having 32 single-precision CUDA Cores, an instruction buffer, a warp scheduler, 2 texture mapping units and 2 dispatch units. In Pascal, an SM (streaming multiprocessor) consists of between 64-128 CUDA cores, depending on if it is GP100 or GP104.Īrchitectural improvements of the GP100 architecture include the following: The shader units in GP104 have a Maxwell-like design. The Tesla P100 (GP100 chip) has a different version of the Pascal architecture compared to the GTX GPUs (GP104 chip). In March 2014, Nvidia announced that the successor to Maxwell would be the Pascal microarchitecture announced on and released on May 27 of the same year. If there are enough damaged FP64 units, then the GPU is downgraded for use in a consumer card.Die shot of the GP106 GPU found inside GTX 1060 cards Just like sharders are disabled because they are damaged and the GPU is used in a lower tier card the same might be done with FP64 units. Now it also could be entirely a yield thing too. Cards that use the same GPU cores have far lower FP64 performance in consumer cards despite the FP64 units being present in the GPU. And that's pretty much how it all goes in the consumer space vs the professional space. So there are just far more FP64 units disabled(but still physically there) in the RTX3090 or the performance is nerfed. However, the Quadro A6000's FP performance is 1:32 of the FP32 but the RTX3090 is 1:64. So the FP64 units in the cards is the same. The RTX3090 and Quadro A6000 both use the same GA102 GPU core. However, in other cards the FP64 performance is just nerfed. The GA100 used in Ampere high end compute cards does have more FP64 units than the GA102 used in the RTX3090/3080. Yes, in the Ampere GPUs, that is the case I believe.
