AMD's high-end data center APU, the AMD Instinct MI300A, has been benchmarked on Geekbench 6.3.0. The performance of the MI300A in Geekbench 6.3.0 was lower than that of the Core i5-14600K across a variety of tests. According to the Geekbench 6.3.0 benchmark results, the MI300A in a single-core test scored 1988 points, while the Core i5-14600K scored 2806 points. In a multi-core test, the MI300A scored 11908 points, while the Core i5-14600K scored 19368 points. The difference in performance between the two is quite noticeable. The MI300A is a top-tier data center APU designed for high-performance computing, and it was expected that it would outperform the mainstream consumer CPU, such as the Core i5-14600K. However, in the Geekbench 6.3.0 benchmark, the MI300A's performance was significantly lower than that of the Core i5-14600K. This is a worrying sign for AMD, as the MI300A is expected to be a competitor to the NVIDIA GeForce RTX 3090, RTX 3080, and RTX 4000 in the data center market. The difference in performance between the MI300A and the Core i5-14600K is quite significant. The MI300A is equipped with 64个Zen 4 cores and 256个VE硬件加速器，但其性能表现并不出色， compared to the performance of the Ryzen Threadripper PRO series, it is still slightly better than the MI300A. However, compared to high-end consumer CPUs like the Ryzen Threadripper PRO series, the MI300A's performance is still significantly lower. This may indicate a potential design issue with the MI300A, or it may be a limitation of the Geekbench 6.3.0 benchmark itself.
