Intel Core i9-13900K was up to 60% faster than Core i9-12900K in 7-Zip tests

The Core i9-13900K, the upcoming Raptor Lake flagship, was tested in data compression and decompression tasks using the 7-Zip archiver.
The new processor was up to 60% faster than the current flagship Core i9-12900K processor.Image source: VideoCardzIn the task of compressing (archiving) files the new processor was about 20% faster than the flagship Alder Lake chip.
But during decompression (unarchiving) files new chip showed 60% faster performance - Core i9-13900K showed 231 GIPS, and Core i9-12900K - 144 GIPS.

However, the source that provided the test results did not share information about the motherboards and RAM capacity.Core i9-13900K.
Image source: Twitter / @OneRaichuThe Core i9-13900K's significant performance gain in 7-Zip is due to its higher clock speed as well as the increased number of cores.
Screenshots provided by user @OneRaichu show that during the tests, one of the Core i9-13900K's high-performance cores was running at 5716 MHz, and the average frequency of its 16 virtual threads was 4611 MHz.
For the Core i9-12900K the values were 5021 and 4060 MHz respectively.The launch of the 13th generation Intel Core processors is expected in mid-October.
The new products are to be announced on September 27th at Intel Innovation event.
