Intel's next Xeon CPUs, dubbed Granite Rapids, may come with massive cache improvements over their predecessors. While the high-end Emerald Rapids SKUs ship with up to 320MB of L3 cache, the flagship Granite Rapids chips are said to offer a whopping 480MB of L3 cache. The news comes from tipster @instlatx64 (via Tom's Hardware ) who spotted a recent leak inside the SDE 9.33.0 (Software Development Emulator) update where Intel added up to 480MB of L3 cache for 6th generation CPUs. has listed its Granite Rapids Xeon. If the list is accurate, that means a 50% increase over Emerald Rapids and should help Intel compete with AMD in the server and high-end desktop space.
It's worth Fax Lists noting that AMD currently offers its Genoa-X 3D V-Cache processor with up to 1,152MB of L3 cache, so it remains to be seen if Intel has anything to compete with products with such high cache capacity. While the company has publicly stated that it plans to offer CPUs with 3D-stack cache in the future, it's unclear when these chips will be ready for pre-production. As of L3 cache on #GraniteRapids increases to 480MB, 1.5 times the 320MB of #EmeraldRapidsjJw0zDCsVB — InstLatX64 (@instlatx64) January 20, 2024 Launched in December 2023, Emerald Rapids has already brought a vast improvement in L3 cache size compared to the Sapphire Rapids family that was launched earlier in the year.
While the flagship Sapphire Rapids chip only had 105MB of L3 cache, the Emerald Rapids tripled that and the top chips in shipping with 320MB of good stuff. Expected to launch in the second quarter of this year, the Granite Rapids CPUs feature only Performance cores and are based on the Birch Stream platform. They offer increased core counts and higher clock speeds compared to their predecessors, and also include FP16 to improve precision support for AI developers. Intel also claims that Granite Rapids Xeon chips offer a 2.9x increase in AI inference (DeepMD+LAMMPS), a 2.8x increase in memory bandwidth and up to 3x better performance in AI workloads compared to Sapphire Rapids Xeon CPUs.
