It appears the recent U.S. export restrictions, initially targeting H20 accelerators, have now been extended to Nvidia's consumer-grade RTX 5090D for China. As such, the company is reportedly developing a further cut-down option, the RTX 5090DD, as an alternative. Reported details from MEGAsizeGPU and specifications by Kopite indicate a significant reduction in GPU bandwidth, which is a trend that might extend to other finer aspects as well, like ROP counts and AI TOPs.
Last month, reports alleged that Nvidia is halting deliveries of its RTX 5090D GPUs to China, following the recent ban on the export of its H20 chips. Washington's primary concern stemmed from the potential of these GPUs, particularly their high GPU bandwidth, to be used in China's supercomputing efforts. On the server side, Nvidia is reportedly pivoting to a Blackwell-based design with GDDR7 memory as the successor to the H20, though specific details remain under wraps.
