Template:mpu Centriq 2434 is a 64-bit 40-core ARM high-performance server microprocessor designed by Qualcomm and introduced in late 2017. This processor, which is based on the Falkor microarchitecture, is fabricated on Samsung's 10LPE process. The 2434 has a base frequency of 2.3 GHz with a TDP of 110 W and a turbo frequency of 2.5 GHz. This chip supports up to 768 GiB of hexa-channel DDR4-2666 memory.

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.
