Graviton3E

AWS Graviton3 is a tetrahexaconta-core ARMv8 microprocessor designed by Amazon (Annapurna Labs) for Amazon's own infrastructure. Graviton3 is a 5 nm 7-chiplet design SoC based on the Arm CMN-650 mesh interconnect and Neoverse V1 core microarchitecture. This chip supports octa-channel DDR5-4800 ECC memory along with 32 lanes of PCIe 5.0.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
