News and articles for the Intel Atom C2750 and the Intel Core i9-12900K
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.
