Numerous benchmarks of the Intel Core i5-10400, 6-core processor, and 12-core processing leaked from China at a Base / Turbo frequency of 2.90 / 4.30 GHz which was compared to its predecessor, the Intel Core i5-9400F, a variant without GPU, which offers 6 cores and 6 threads at a Base / Turbo frequency of 2.90 / 4.10 GHz. As already reflected in the paper, the Intel CPU will be much superior in all those applications that take advantage of multithreading and the 6 extra threads that are incorporated.
Due to this, in the single-core tests, there are very few differences, and that is that in the single-core benchmarks, the Comet Lake-S CPU is between 2-5% faster, something normal considering that its Turbo frequency is 4.8% higher so that gain is only tied to the higher speed.
When we talk about multicore tests, we already see great differences, and that is that we see a difference of up to 41.85% in the Cinebench R20 or 45.05% in the Cinebench R15, making clear the overwhelming superiority that integrating HyperThreading now implies in an Intel Core i5.
If we are looking for a rival in AMD, our Ryzen 5 1600 AF (110 euros) gave a score of 2570 vs 3185 points (+3000 with overclock) and 1153 v 1333 points respectively, which translates into a difference in performance in favor of the Intel CPU of 23% and 15%, but of course, something more expensive, such as a Ryzen 5 3600X (220 euros), would be about 10-15% faster than the Intel option that would cost around 200 euros and no overclocking capability. 175 euros if we talk about the Core i5-10400F.
