Core i3-9100T vs i7-9750H


Description
Both models i3-9100T and i7-9750H are based on Coffee Lake architecture.

Coffee Lake is the second refinement of Intel’s 14nm (Tri-Gate) technology. While it uses LGA1151 socket, it is incompatible with previous generations due to electrical changes in socket’s pins so these CPUs require Z370 chipset. This kind of generation introduced more cores in every range to compete with new AMD’s architecture. Coffee Lake uses DDR4 memory at 2400MHz for i3 and at 2666MHz for i5, i7 CPUs plus iGPU frequency has been increased 50MHz with respect to previous generation.

Using the multithread performance as a reference, the i3-9100T gets a score of 192.9 k points while the i7-9750H gets 286.4 k points.

Summarizing, the i7-9750H is 1.5 times faster than the i3-9100T. 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.
