Core i5-10400 vs i5-10400F


Description
Both models i5-10400 and i5-10400F are based on Comet Lake architecture.

Comet Lake was released in 2019 as a 14nm process-refinement. These models were released as 10th generation CPUs like 10nm Ice Lake. There are model with 2 to 10 cores.

Using the multithread performance as a reference, the i5-10400 gets a score of 367.7 k points while the i5-10400F gets 370 k points.

Summarizing, the i5-10400F is 1 times faster than the i5-10400. To get a proper comparison between both models, take a look to the data shown below.

AVX2 optimized benchmark
The benchmark in mode III (AVX2), like AVX1, is optimized to used 256 bits registers beside the second version of the Advanced Vector Extensions (AVX). The first AVX2 compatible CPU was released in 2013.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.

Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.

If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
