Core i5-10400 vs Engineering Sample 906ED 2.1GHz


Description
Both models i5-10400 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 i5-10400 gets a score of 372.2 k points while the 906ED 2.1GHz gets 657.2 k points.

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