Core i9-10940X vs i9-10980XE


Description
Both models i9-10940X and i9-10980XE are based on Cascade Lake architecture.

Cascade Lake is a architecture focused on high-end CPUs that uses the 14nm process. There are i9 and Xeon models using 4 different cores: Cascade Lake-SP and Cascade Lake-AP for servers, Cascade Lake-W for workstations and Cascade Lake-X for home high-end Pcs.

Using the multithread performance as a reference, the i9-10940X gets a score of 1088.1 k points while the i9-10980XE gets 1241.1 k points.

Summarizing, the i9-10980XE is 1.1 times faster than the i9-10940X. 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.
