Intel Core i5-12400 = 100

The Intel Celeron 4305U scores 1,197 in single-core performance and 1,615 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,390 for overall performance, 2,726 for productivity performance, 3,043 for creator performance, 1,504 for engineering performance and 3,995 for gaming performance. Its multi-core throughput works out to 808 per core, 808 per thread and 108 per watt. Its computed efficiency index is 359. Its performance index is 17, so its overall performance is 83% 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.
