Intel Core i5-12400 = 100

The AMD EPYC 7261 scores 1,005 in single-core performance and 11,149 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,347 for overall performance, 8,654 for productivity performance, 7,941 for creator performance, 11,428 for engineering performance and 5,802 for gaming performance. Its multi-core throughput works out to 1,394 per core, 697 per thread and 72 per watt. Its computed efficiency index is 269. Its performance index is 41, so its overall performance is 59% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

How these scores are computed

Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.

  • Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
  • Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
  • Creator performance is 0.55 times multi-core plus 1.8 times single-core.
  • Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
  • Gaming performance is 3 times single-core plus 0.25 times multi-core.
  • Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
  • The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
  • The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
