Two months after it was banned by US government from selling high-performance AI chips to China, NVIDIA has introduced a new A800 GPU designed to bypass those restrictions.
The new NVIDIA A800 is based on the same Ampere microarchitecture as the A100, which was used as the performance baseline by the US government.
Despite its numerically larger model number (the lucky number 8 was probably picked to appeal to the Chinese), this is a detuned part, with slightly reduced performance to meet export control limitations and the 33% reduced NVLINK speed is hardly noticeable. It can only be stacked to 8-GPUs per system, not 16 like the A100. This card is the industry standard and premier value choice for ever demanding high-end AI and CGI workloads.
Ships in 10 days from payment. Limited allocations available. 3-year warranty included. All sales final. No returns or cancellations. For volume pricing, consult a live chat agent or call our toll-free number.
Update 04.10.2023: 200 units have just arrived and are now available for immediate purchase. Any further quantities require a 4-6 week lead time.
