At GTC 2017, Nvidia announced the Nvidia Volta Tesla V100 graphics card that is based on the GV100 GPU. Rumors claimed that we would be able to see Nvidia Volta based GPUs at the event and it turns out that those rumors were indeed correct. The confusion regarding the memory type has also been cleared out and the Nvidia Volta Tesla V100 uses HBM2 memory instead of GDDR6.
The Nvidia Volta Tesla V100 comes in two different designs, a single slot version and a dual slot version as well. The single slot version has a TDP of 150W, while the dual slot version has a TDP of 300W. Both graphics cards feature 5120 Volta CUDA cores and 16GB of HBM2. The GPU has been built using the 12nm FinFET process by TSMC.
The Nvidia Volta Tesla V100 features a clock speed of 1455MHz and it is important to note here that the GPU is not fully unlocked. While the GV100 GPU has 5376 CUDA cores the card only uses 5120 of those GPUs. This is not surprising as same was the case with the P100 as well.
At 300w the Nvidia Volta Tesla V100 is able to deliver 15 TFLOPS of single precision compute and 7.5 TFLOPS of double precision compute which is very impressive indeed. Talking about the little brother, the 150W version, it is clear that it will not be able to perform as well as the 300W version but it will be close. Nvidia has not given details regarding how close so stay tuned for more.
Talking about the performance benefits of using Nvidia Volta, according to the company, Volta provides a 40% performance boost as compared to Pascal. We know that Pascal was a huge leap forward and getting 40% better performance over that is more than what we could have asked for. Other improvements are as follows:
- New mixed-precision FP16/FP32 Tensor Cores purpose-built for deep learning matrix arithmetic;
- Enhanced L1 data cache for higher performance and lower latency;
- Streamlined instruction set for simpler decoding and reduced instruction latencies;
- Higher clocks and higher power efficiency.
The Nvidia Volta Tesla V100 is very impressive on its own but I for one was expecting to see a consumer level GPU. That would have been way more interesting. At least we know for sure that Nvidia Volta is here. This means that there will be a consumer level GPU in the works and we could see one coming out soon.
Let us know what you think about Nvidia Volta and whether or not you would upgrade if you already own a Pascal GPU.
