AMD Ryzen 7000 and Intel Core i 13 Gen at almost 6 GHz clock speed

Posted by Stefan on 2022-08-29

In September, both AMD and Intel are introducing their new mainstream desktop processors. It doesn't seem to have been as close as this year for a long time, leaked benchmarks of the new top models from AMD and Intel point to a head-to-head race.

This year even the 6 GHz clock limit is almost within reach. With a good cooler and some overclocking it should be possible to reach the 6 GHz limit. But even in series production, the manufacturers try to realize the highest possible clock frequency, at least on one core.

Intel Core i7-13700K could debut with 16 cores and 24 threads

Posted by Stefan on 2022-07-20

According to an internal Intel slide published at the end of last year, the Intel Core i7-13700K could have 8+8, i.e. 16 CPU cores that provide 24 threads. The interesting thing about the slide is that it was recently confirmed by newer leaks of the Intel Core i9-13900K and the Intel Core i5-13600K as the number of cores and also the size of the cache matches with recently published CPU-Z screenshots of alleged development models.

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 !
