Dissecting the Geekbench listing, it looks like the test platform was part of a 2S configuration that was running dual Intel Sapphire Rapids Xeon CPUs. The engineering sample is listed as Family 6 Model 143 Stepping 2 which confirms that it is part of the Sapphire Rapids lineup & based on the Intel 10nm ESF (Enhanced SuperFin) architecture with Golden Cove cores.
Each CPU features 20 cores and 40 threads & makes up a total of 40 cores and 80 threads for the server itself. Each chip features 75.0 MB of L3 (37.5 MB per chip) and 20.0 MB of L2 cache per chip. Both of these caches have seen a significant boost over the Ice Lake Xeon CPUs.
As for clock speeds, since the Intel Sapphire Rapids Xeon CPU is still an early engineering sample, it has a base clock of 1.50 GHz but can boost up to 4.7 GHz as reported by Geekbench. We cannot say how accurate these clock speeds are but they do look pretty high for a server platform so it could likely be a high-clock optimized chip. The other possibility is like I said, a faulty clock speed which is a very common scenario within the Geekbench database.
The Intel 20 Core & 40 Thread Sapphire Rapids Xeon CPU was tested within the older Geekbench 4 benchmark with 32 GB of memory (presumably DDR5 since that is what the next-generation Xeon chips support) and well, performance was quite lackluster with a single-core score of 1340 points & a multi-core score of 31,666 points. Again, these are results from a very early sample and an older & outdated benchmark so we can see performance improvements in later benchmarks. Sapphire Rapids is pitted for a launch next year so it will take time for better samples to appear in databases.
Here’s Everything We Know About Intel’s 4th Gen Sapphire Rapids Xeon CPUs
The Sapphire Rapids-SP family will be replacing the Ice Lake-SP family and will go all on board with the 10nm Enhanced SuperFin process node that will be making its formal debut later this year in the Alder Lake consumer family. From what we know so far, Intel’s Sapphire Rapids-SP lineup is expected to utilize the Golden Cove architecture and will be based on the 10nm Enhanced SuperFin process node.
The 31666 multi-core benchmark is very high, as compared to earlier generations. The 1340 single-core benchmark is also impressive. DDR5 contributes to the improved performance, as does the higher clock speeds with the 10nm ESF process point.
VisualSim has some Intel Xeon/Nehalem processor models:
