Intel Emerald Rapids Xeon Processor Die Shot Charts and Performance Metrics Revealed
【Lansheng Technology News】Intel plans to launch its 5th generation Xeon processors, codenamed Emerald Rapids, on December 14, using the same socket and platform as Sapphire Rapids.
The Emerald Rapids processor is equipped with a Raptor Cove core and can package up to 64 cores at a time; the difference from Sapphire Rapids is the tile structure, Emerald Rapids has 2 tiles; while Sapphire Rapids has 4 tiles.
In terms of CPU layout, 2 cores are connected to the cache array through Modular Die Fabric, with a total of 4 memory controllers, supporting up to 8-channel DDR5-5600 memory.
In addition, there are 6 PCIe controllers between the two dies, as well as 4 UPI channels and 4 accelerator engines.
Emerald Rapids has significantly improved the cache structure. Intel's L3 cache capacity has increased from a maximum of 112.5MB to a maximum of 448MB. Additionally, 2MB of L2 cache is reserved for each core.
In order to get clear differences between the 4th generation Xeon and 5th generation Xeon products, Intel compared the two series of flagships.
That includes the Sapphire Rapids-based 8480+, which has 56 cores, and the 8592+, which has 64 cores and more L3 cache.
Across various benchmarks, Intel does promise significant leaps in performance.
Scheduled to launch in 2024, Granite Rapids will be built using the Intel 3 (3nm level) process Redwood Cove P-core and is expected to come with 88 cores for the SP variant and 132 cores for the AP variant.
