How do the benchmark scores compare?
AMD EPYC 9455P has a PassMark single-core score of 3,745, compared with 3,152 for Intel Xeon 6781P. AMD EPYC 9455P has the higher score in this benchmark.
AMD EPYC 9455P has a PassMark multicore score of 116,927, compared with 117,946 for Intel Xeon 6781P. Intel Xeon 6781P has the higher score in this benchmark.
Single-core scores describe one thread; multicore scores describe aggregate CPU throughput. These results do not establish which CPU is faster in every application. Compare platform support and total upgrade cost before buying.
AMD EPYC 9455P lists SP5; Intel Xeon 6781P lists FCLGA4710. Check the motherboard manufacturer's CPU support list and BIOS requirements. If the required platform changes, include motherboard, memory and cooling costs; the CPU price alone is not the full upgrade cost.

The retrieval date records when Find Me a CPU collected the source data. It is not a benchmark test date. Prices are USD estimates from the source, converted for other currencies, rather than live retailer offers. Release / first seen means the CPU first appeared on PassMark charts, not necessarily its launch date.
Benchmark scores do not predict frame rates in a particular game. Typical TDP is a specification, not measured electricity use. A matching socket does not confirm motherboard support; check the manufacturer's CPU support list and BIOS requirements.
