Core i5-10400F vs Engineering Sample 906ED 2.1GHz


Description
Both models i5-10400F and 906ED 2.1GHz 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 i5-10400F gets a score of 370 k points while the 906ED 2.1GHz gets 657.2 k points.

Summarizing, the 906ED 2.1GHz is 1.8 times faster than the i5-10400F. To get a proper comparison between both models, take a look to the data shown below.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs
