EPYC 7252 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 two compute dies fabricated on a TSMC 7 nm process and an I/O die fabricated on a GlobalFoundries 14 nm process. The 7252 has a TDP of 120 W with a base frequency of 2.8 GHz and a boost frequency of up to 3.2 GHz. This processor supports up to two-way SMP and up to 4 TiB of memory per socket.
Cache[edit]
- Main article: Zen 2 § Cache
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[edit]
This model supports up to 8 channels of up to DDR4-3200 memory[1][2] 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 two compute dies (effective bandwidth ≈ 55 GB/s per CCD at 1.46 GHz FCLK[3]). 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).[2]
