Core i7-6820HQ vs Xeon Silver 4110


Description
Both models i7-6820HQ and 4110 are based on Skylake architecture.

Sky Lake is also known as 6th generation Core. Include Thunderbolt 3.0, SATA Express and Iris Pro graphics with DirectX 12. It uses LGA 1151 socket for mainstream models and LGA 2066 for X-Series. Sky Lake comes with AVX2 support in all mainstreams CPUs and AVX-512 in some high end models.

Using the multithread performance as a reference, the i7-6820HQ gets a score of 206.3 k points while the 4110 gets 281.5 k points.

Summarizing, the 4110 is 1.4 times faster than the i7-6820HQ. 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

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.
