AMD’s Radeon Instinct MI300X accelerator was first introduced in late 2023 and has made an impressive debut on Geekbench’s OpenCL benchmark. The GPU took first place, beating all rivals, including Nvidia’s RTX 4090, which it pushed to second place.
The Radeon Instinct MI300X is built on AMD’s third-generation CDNA architecture and TSMC’s advanced 5nm and 6nm processes. It features 19,456 stream processors, 192 GB of HBM3 memory, 304 computing units, 1,216 matrix cores and a TDP of 750 watts.
These specs led to the MI300X achieving a whopping OpenCL benchmark result of 379,660, significantly higher than the RTX 4090’s score of around 320,000. Geekbench’s tests were performed on a Supermicro AS-8125GS-TNMR2 system equipped with an AMD EPYC 9754 CPU.
A small price difference
As might be expected, the MI300X showed impressive performance in all benchmarks. In addition to the OpenCL score of 379,660, it delivered 435.2 images/sec in background blur, 279.7 images/sec in face detection, 18.4 Gpixels/sec in horizon detection, 42.4 Gpixels/sec in edge detection, 33.7 Gpixels/ sec in Gaussian Blur, 1.28 Gpixels/sec in Feature Matching, an excellent 1.59 Tpixels/sec in Stereo Matching and 74,430.6 FPS in Particle Physics.
Comparing the MI300X to Nvidia’s RTX 4090 is clearly unfair, as the two products are tailor-made for very different markets. The MI300X is intended for data centers, AI applications and high-performance computing tasks that require a lot of memory and processing power. It is a direct competitor to Nvidia’s H100. The RTX 4090, on the other hand, is designed primarily for gamers and creative professionals.
Another important distinction between the two GPUs is the price. While the RTX 4090 will run consumers around $1,700 on Amazon, the MI300X has a price tag of over $15,000.
