Core i7-10870H vs i7-10510U


Description
Both models i7-10870H and i7-10510U 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 i7-10870H gets a score of 487 k points while the i7-10510U gets 191.4 k points.

Summarizing, the i7-10870H is 2.5 times faster than the i7-10510U. 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.
