AMD pulverizes Nvidia's RTX 4090 in popular Geekbench OpenCL benchmark — but you will need a small mortgage to buy AMD's fastest GPU ever produced

Radeon Instinct MI300X.

First introduced in late 2023, AMD’s Radeon Instinct MI300X accelerator has made an impressive debut on Geekbench's OpenCL benchmark. The GPU took the top spot, thrashing all rivals, including Nvidia's RTX 4090, which it pushed down into second place.

The Radeon Instinct MI300X is built on AMD's third-generation CDNA architecture and TSMC's advanced 5nm and 6nm processes. It boasts 19,456 stream processors, 192GB of HBM3 memory, 304 compute units, 1,216 matrix cores, and a TDP of 750 watts.
