Template:mpu Centriq 2452 is a 64-bit 46-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 2452 has a based frequency of 2.2 GHz with a TDP of 120 W and a turbo frequency of 2.6 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. |
