According to @BenchLeaks on Twitter, two prototype Intel Xeon Platinum 8468 Sapphire Rapids 48 core server processors were recently evaluated in Geekbench 5. Even though these chips aren’t the top-of-the-line 56-core models, they displayed some outstanding performance numbers, matching AMD’s best-of-the-best twin EPYC 64-core configuration in the same benchmark.
Twin Xeon Platinum 8468 CPUs with a combined 96 cores and 192 threads were installed in the Sapphire Rapids system that was shared. A single-threaded score of 1,257 points and a multi-threaded score of 74,586 points were produced by the two processors working together.
Twin AMD EPYC 7763 processors with a combined core count of 128 cores and 256 threads are one of the best dual AMD EPYC processor configurations we could locate on Geekbench 5 for comparison.
In the single-threaded test, both Intel Sapphire Rapids and AMD’s EPYC chips scored 1249 points, and in the multi-threaded test, they scored 75,539.
As a result, there is just a 1% performance difference between the two platforms’ single- and multi-core performance. However, if we examine the performance of each core individually under a multi-threaded workload, Intel is 23% quicker than AMD.
This is significant since single-threaded benchmarks only reveal an individual core’s peak performance when all other cores are inactive, allowing that core to utilise extra power and thermal reserves. Individual core performance under load thus reveals the characteristics of each core under the most demanding conditions.
However, it should be noted that Geekbench 5 is not a particularly helpful benchmark for outcomes of real-world performance. So, treat this information with caution. On the other hand, Geekbench at least allows us to get a broad picture of how well Sapphire Rapids performs.
