If there are enough damaged FP64 units, then the GPU is downgraded for use in a consumer card. 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. Use the same num_iterations in benchmarking and reporting.That's not always true.Check the repo directory for folder -.logs (generated by benchmark.sh).Input a proper gpu_index (default 0) and num_iterations (default 10).Step One: Clone benchmark repo git clone https: ///lambdal/lambda-tensorflow-benchmark.git -recursive Step Two: Run benchmark Share your results by emailing or tweeting Be sure to include the hardware specifications of the machine you used. FP32 - Number of images processed per second Model / GPUįP16 - Number of images processed per second Model / GPUĪll benchmarking code is available on Lambda Lab's GitHub repo. Note that the unit measured is # of images processed per second and we rounded results to the nearest integer. The tables below display the raw performance of each GPU while training in FP32 mode (single precision) and FP16 mode (half-precision), respectively. The Titan RTX, 2080 Ti, Titan V, and V100 benchmarks utilized Tensor Cores.The "Normalized Training Performance" of a GPU is calculated by dividing its images / sec performance on a specific model by the images / sec performance of the 1080 Ti on that same model.For each GPU/model pair, 10 training experiments were conducted and then averaged.All models were trained on a synthetic dataset to isolate GPU performance from CPU pre-processing performance and reduce spurious I/O bottlenecks.price isn't important, you need every bit of GPU memory available, or time to market of your product is of utmost important. Tesla V100 is the best GPU for Machine Learning / Deep Learning if.At half-precision, the Titan RTX offers effectively 48 GB of GPU memory. If you're already successfully training at FP16 and 11 GB still isn't enough, then choose the Titan RTX - otherwise, go with the RTX 2080 Ti. This effectively doubles your GPU memory at the cost of training accuracy. However, before concluding this, try training at half-precision (16-bit). 11 GB of memory isn't sufficient for your training needs. Titan RTX is the best GPU for Machine Learning / Deep Learning if.The 2080 Ti offers the best price/performance among the Titan RTX, Tesla V100, Titan V, GTX 1080 Ti, and Titan Xp. 11 GB of GPU memory is sufficient for your training needs (for many people, it is). RTX 2080 Ti is the best GPU for Machine Learning / Deep Learning if.Performance FP64 (double) 379.7 GFLOPS: 465. Titan RTX: $2,499.00 (source: NVIDIA's website) Comparison between Nvidia Titan Xp and Nvidia GeForce RTX 3080 with the specifications of the graphics cards, the number of execution units, shading units, cache memory, also the performance in benchmark platforms such as Geekbench or Antutu. Stay tuned for comparison to the V100 (32 GB).When comparing # images processed per second while training. ~14% slower that the Tesla V100 (32 GB).Multi-GPU training speeds are not covered.īenchmarks were conducted on Lambda's deep learning workstation with 2x Titan RTX GPUs. We measured the Titan RTX's single-GPU training performance on ResNet50, ResNet152, Inception3, Inception4, VGG16, AlexNet, and SSD.
