The Xeon Platinum 8480+ CPU from the Intel Sapphire Rapids server processor has been tested using Geekbench 5. These are not the first leaked benchmarks for Intel’s Sapphire Rapids-SP Server CPUs, but this is the first time the Xeon Platinum 8480+ has been spotted in Geekbench 5. The same chip will be one of Intel’s highest-end products in its 4th Gen Datacenter range and will feature several high-end characteristics that, if not for the numerous delays, would have made it a formidable opponent for AMD’s EPYC Milan. AMD’s EPYC Genoa, which boasts significantly more cores and threads, will suddenly be the CPU lineup’s fiercest competition.
Some of the most important positions in the single-threaded HPC and multi-threaded (Multi-Socket 2S+) platforms may still be held by Intel’s Sapphire Rapids-SP CPUs. The Xeon Platinum 8480+, which uses the Golden Cove architecture, has 56 cores and 112 threads according to the specifications for Intel’s top processor. The Xeon Platinum 8380, the Ice Lake flagship, has 80 threads and 40 cores based on the Sunny Cove architecture. Genoa will increase them to 96 cores and 192 threads from the EPYC Milan CPUs’ greater core count of 64 cores and 128 threads.
The CPU has a total cache of 217 MB, consisting of 105 MB of L3 cache and 112 MB of L2 cache. 110 MB of total cache (50 MB L2 + 60 MB L3) were available on the Intel Xeon Platinum 8380 Ice Lake-SP CPU as a point of comparison. That is almost a 2-fold increase in the cache. The Milan-X chip, on the other hand, boasts up to 800 MB of cache (512 MB 3D V-Cache + 288 MB L2+L3), while AMD’s third-generation EPYC Milan chips continue to boast a greater cache of 288 MB. The next Genoa chips are anticipated to feature up to 1248 MB of 3D V-Cache and 480 MB of non-3D V-Cache cache, respectively.
The Intel Sapphire Rapids Xeon Platinum 8480+ CPU had a base clock speed of 2.0 GHz, while typical clock frequencies were in the same general range.
The base and boost clocks on the Intel Ice Lake-SP Xeon Platinum 8380 are both 2.3 GHz. According to reports, the final retail Sapphire Rapids-SP Xeon Platinum 8480+ CPU will include a 3.0 GHz boost clock and a 350W TDP.
Despite having a 15% clock speed advantage over the Sapphire Rapids-SP CPU, the Ice Lake-SP chip outperformed it in single-threaded tests by only 3%. The Xeon Platinum 8480+ outperformed other processors in multi-threaded testing by a factor of 35 while having a core and thread count advantage of 40%.
Again, these cores were operating at a lower clock speed, thus we may anticipate the final variations to perform 40–50% better than Ice Lake equivalents. SP’s We’d love to include some EPYC benchmarks in the mix, but that won’t be a fair comparison because the Xeon Platinum CPUs have tested under Windows Server 2022 Datacenter, and the majority of EPYC results are under Linux.
