The Intel Core i9-10920X processor was introduced at the beginning of the month, and will go on sale in November. This is a 12-core HEDT CPU, operating at frequencies of 3.5-4.8 GHz, which is priced at 689 dollars.
That is, the Ryzen 9 3900X with 12 cores and frequencies of 3.8-4.6 GHz and a price of $ 500 can not be called a direct competitor to the new Intel due to the difference in price, but it is interesting to compare these processors, since the number of cores is identical, and the frequencies very similar.

And we have the opportunity to compare them in 3DMark Fire Strike. Core i9-10920X just registered in the benchmark database, gaining 26,849 points. To clarify, we are talking about Physics Points, which are not dependent on the video card.
The Ryzen 9 3900X scores about 28,800 points in the same test, that is, about 7% more. Of course, it is not worth making conclusions on one test, but it may turn out that a more affordable consumer AMD processor will be faster than the new Intel processor from the HEDT family.
