Core i5-10400T


Description
The Core i5-10400T is a cpu manufactured by Intel that was released on April 2020. This model has 6 Comet Lake-S cores with HyperThreading, runs at 2000 MHz as base frequency and has a a thermal design power of 35 W.

The i5-10400T has 6x32+6x32 kB of cache L1, 6x256 kB of cache L2 and 12288 kB of cache L3.

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.

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.
