The engineering samples of the Core i9-9900K processor with eight cores and solder under the cover got so widespread that the results of their testing appear in profile databases every day. At least recently, in Geekbench 4.2.3, a copy with strange frequencies 3.1 / 4.5 GHz scored 5786 points in the “single-core” part of the test, and in the “multi-core” demonstrated an account of 30 050 points.
A later result in the same test indicated the use of a different brand motherboard, and the processor frequencies were identical to the expected nominal – 3.6 / 5.0 GHz. It’s natural that the test results showed a higher score – 6,248 and 33,037, respectively.
It is interesting that in both cases the Core i9-9900K processor appears in the database under the symbol “Kaby Lake”.
