Nvidia Introduces Ampere Workstation GPUs: RTX A400 vs RTX A1000 – Specs and Release Dates

Nvidia has introduced two workstation GPUs in the A series. This concerns the RTX A400 and the RTX A1000. Both GPUs are based on the Ampere architecture. The A1000 is available now, the A400 will follow later this year.

As there are two GPUs the new entry-level models among Ampere workstation GPUs. Both cards have the highest rating total board power of 50W and four Mini DisplayPort 1.4a ports. The A400 has 4GB of GDDR6 memory; the A1000 has 8GB of this memory. The A1000’s memory bus is twice as large, with 128 bits instead of 64 bits. The A1000 has twice the memory bandwidth: 192 versus 96GB/s.

The A1000 has more CUDA, Tensor, and ray tracing cores than the A400. The A1000 has 2304 CUDA, 72 Tensor and 18 ray tracing coils, compared to 768, 24 and 6 respectively So the A1000 has more computing power than the A400, with 6.7Tflops singlenesscomputing power, 13.2Tflops searching computing power and 53.8Tflops Tensor computing power. These values ​​for the A400 are 2.7, 5.4 and 21.7 respectively.

Both GPUs have active cooling with one fan and are 6.9 cm high and 16.3 cm long. Both GPUs have a PCIe 4.0 x8 interface and a single-slot design. The A1000 is now available for sale worldwide; the A400 should be available from May. Nvidia is still not commenting on recommended prices.
