AMD started AMD EPYC 7451 sales 20 June 2017 at a recommended price of $2,400. This is Naples architecture desktop processor primarily aimed at office systems. It has 24 cores and 48 threads, and is based on 14 nm manufacturing technology, with a max turbo frequency of 2300 MHz - 3200 MHz (1 core)3200 MHz (2 cores)3200 MHz (3 cores)3200 MHz (4 cores)3200 MHz (5 cores)3200 MHz (6 cores)3200 MHz (7 cores)3200 MHz (8 cores)3200 MHz (9 cores)3200 MHz (10 cores)3200 MHz (11 cores)3200 MHz (12 cores)2900 MHz (13 cores)2900 MHz (14 cores)2900 MHz (15 cores)2900 MHz (16 cores)2900 MHz (17 cores)2900 MHz (18 cores)2900 MHz (19 cores)2900 MHz (20 cores)2900 MHz (21 cores)2900 MHz (22 cores)2900 MHz (23 cores)2900 MHz (24 cores) and an unlocked multiplier.
Compatibility-wise, this is AMD Socket TR4 processor with a TDP of 180 Watt. It supports DDR4 Eight-channel memory.
It provides poor benchmark performance at 23.32 percent of a leader's which is AMD EPYC 7763.
Of EPYC 7451 processor market type (desktop or notebook), architecture, sales start time and pricing.
Basic microprocessor parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. These parameters can generally indicate CPU performance, but to be more precise you have to review its test results.
Information on EPYC 7451 compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.
