the powerful Ampere accelerator in PCIe version increases to 80 GB of HBM2e memory

The accelerator Nvidia A100 was the first Ampere product unveiled by the firm. Intended for the HPC sector (High Performance Computing), son GPU GA100 embeds no less than 54 billion transistors for a large footprint of 826 mm2.

Initially offered in optimized SXM format, the A100 accelerator has also been available in a PCIe version, slightly less efficient but more easily integrated.

The initial version had 40 GB of HBM2 memory (High Bandwidth Memory) and the site Videocardz spotted a variant (not yet announced but apparently expected next week) that will feature 80 GB of HBM2e memory, as much as for the SXM version.

This will allow him to ensure a 2 TB / s bandwidth (against 1.55 TB / s for the version with 40 GB of HBM2) and still with a TDP of 250W. The processing capacities remain the same: 19.5 TFLOPS in FP64, 312 TFLOPS in FP32 and 1248 TOPS in Int8.

This type of product should reach a price of 20 000 dollars, compared to $ 15,000 for the 40 GB version of HBM2.
