Why the new AMD Ryzen 7000 processors for the AM5 socket are currently not a good deal
Posted by Stefan on 2022-10-11
At the end of September 2022, the time had come: AMD presented its latest desktop processors called AMD Ryzen 7000. Initially, 4 processors with 6 to 16 CPU cores were released.
The new socket AM5 (LGA 1718) is used for the first time, which is intended to replace the very durable socket AM4 introduced in 2017 as AMDs mainstream platform. This includes (depending on the chipset) PCIe 5.0 support as well as the exclusive use of DDR5 memory on all AM5 mainboards.
Officially, DDR5-5200 is the maximum, but with AMDs EXPO Technology which is similar to Intel's XMP 3.0, AMD now also has a solution for easy overclocking of the main memory. AMD itself names DDR5-6000 as the sweet spot for the new AMD Ryzen 7000 processors.

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.

First Geekbench 5 benchmark of the Intel Core i7-13700K
Posted by Stefan on 2022-07-26
Last week we already reported on the new Intel Core i7-13700K processor from Intel, which is expected in autumn 2022. With 8+8 CPU cores (24 threads), the Intel Core i7-13700K should have the same configuration as last year's Intel Core i9-12900K. With this, Intel wants to finally clear AMD's lead in multi-core performance, which has existed for several years.
Intel Core i9-13900 benchmark of engineering sample
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.
