EPYC 7232P is a 64-bit octa-core x86 server microprocessor designed and introduced by AMD in mid-2019. This multi-chip processor, which is based on the Zen 2 microarchitecture, incorporates logic fabricated TSMC 7 nm process and I/O fabricated on GlobalFoundries 14 nm process. The 7232P has a TDP of 120 W with a base frequency of 3.1 GHz and a boost frequency of up to 3.2 GHz. This processor supports single-socket configurations only and up to 4 TiB of memory per socket.

This processor has 8 CPU cores and 32 MiB L3 cache. A single Core Complex Die (plus I/O die) can provide these resources, however there seems to be no evidence that AMD produces any Zen 2-based EPYC or Threadripper processors with an odd number of CCDs, and the advertised maximum memory bandwidth appears to exceed the capabilities of a single CCD. The EPYC 7252 SKU notably has the same specifications as this model except for supporting dual-socket systems and offering 64 MiB L3 cache which evidently requires two CCDs.

Cache

Main article: Zen 2 § Cache

[Edit/Modify Cache Info]

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.

Memory controller

This model supports up to 8 channels of up to DDR4-3200 memory with a theoretical maximum bandwidth of 25.6 GB/s (≈ 23.84 GiB/s) per channel, but is apparently bandwidth limited by the IFOP links between the I/O die and its only one (two?) compute dies (effective bandwidth ≈ 55 GB/s per CCD at 1.46 GHz FCLK). According to AMD this processor is "optimized for 4 channels with DDR4-2667 DIMMs" (≈ 21.3 GB/s per channel) and therefore has a "per-socket theoretical memory bandwidth 85.3 GB/s" (≈ 79.47 GiB/s).
