First unveiled in late 2023, AMD's Radeon Instinct MI300X accelerator made an impressive debut in Geekbench's OpenCL benchmark. The GPU took first place, beating all its rivals, including Nvidia's RTX 4090, which it knocked into second place.
Radeon Instinct MI300X is based on AMD's third-generation CDNA architecture and TSMC's advanced 5nm and 6nm processes. It has 19,456 stream processors, 192 GB of HBM3 memory, 304 compute units, 1,216 die cores and a TDP of 750 watts.
These specs led the MI300X to achieve a huge OpenCL benchmark result of 379,660, significantly higher than the RTX 4090's score of around 320,000. Geekbench testing was performed on a Supermicro AS -8125GS-TNMR2 system, equipped with an AMD EPYC 9754 CPU.
A little price difference
As expected, the MI300X demonstrated impressive performance across all benchmarks. In addition to the OpenCL score of 379,660, it delivered 435.2 images/s in Background Blur, 279.7 images/s in Face Detection, 18.4 Gpixels/s in Horizon Detection, 42.4 Gpixels/s in Detection of edges, 33.7 Gpixels/sec in Gaussian Blur, 1.28 Gpixels/sec in Feature Matching, an exceptional 1.59 Tpixels/sec in Stereo Matching and 74,430.6 FPS in Particle Physics.
Comparing the MI300X to Nvidia's RTX 4090 is obviously unfair as the two products are designed for very different markets. The MI300X is for data centers, artificial intelligence applications, and high-performance computing tasks that require extensive memory and processing power. It is a direct competitor to Nvidia's H100. In contrast, the RTX 4090 is designed primarily for gamers and creative professionals.
Another key distinction between the two GPUs is the price. While the RTX 4090 will cost consumers around $1,700 on Amazon, the MI300X is priced north of $15,000.
