Posted by Stefan on 2022-06-15

Intels 13th generation of the Intel Core i series (Raptor Lake) is about to be released and a lot of information is already known from the official side. This information includes e.g. the number of CPU cores, the expected increase in performance and the manufacturing technology of the new CPUs.

We compare the technical data of the Intel Core i9-13900 with its predecessor and look at benchmarks that have already been published.

AMD Ryzen 9 7950X - Cinebench R23 Benchmark projection

Posted by Stefan on 2022-06-10

We give you a preview of AMD's new Zen 4 desktop processors and calculate the performance of the AMD Ryzen 9 7950X top model for the new AM5 socket. The performance data and other technical details come directly from the press kit that AMD released as part of its Financial Analyst Day on June 9, 2022.

Up to 15 percent more single-core performance and 35 percent more multi-core performance of the 16-core model are realistic !
