NVIDIA, the world’s largest graphics cards producer and a leading player in data centre GPUs, is now further expanding the professional data centre line up of Ampere GPUs with the A2 Tensor Core GPU accelerator.
According to sources, this new accelerator from NVIDIA is the most entry-level design we have ever seen from NVIDIA and this GPU will boast some decent specifications based on its entry-level market designation.
Coming to the specifications of the device, the NVIDIA A2 Tensor Core GPU is designed specifically for inferencing and will replace the Turing-powered T4 Tensor Core GPU. This new GPU will be featuring a variant of Ampere GA107 GPU SKU which offers 1280 CUDA cores and 40 Tensor cores.
The cores of the GPU run’s at a clock speed of 1.77 GHz and are based on the Samsung 8nm process node. Only the higher-end GA100 GPU SKUs are based on the TSMC 7nm process node. Memory wise, the design of this new GPU comes with a 16 GB GDDR6 capacity that runs across a 128-bit bus-wide interface, clocking in at 12.5 Gbps effectively for a total bandwidth of 200 GB/s.
NVIDIA’s new A2 Tensor Core GPU operates at a TDP between 40 and 60 Watts, and it also comes in a small form factor design with a Half-Height and Half-Length form factor which is passively cooled. The GPU also features a PCIe Gen 4.0 x8 interface instead of the standard x16 link.
