Geekbench 6 (Single-Core)
Geekbench 6 is a benchmark for modern computers, notebooks and smartphones. What is new is an optimized utilization of newer CPU architectures, e.g. based on the big.LITTLE concept and combining CPU cores of different sizes. The single-core benchmark only evaluates the performance of the fastest CPU core, the number of CPU cores in a processor is irrelevant here.

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.

Description of the processor
The AMD Ryzen 9 7900X is a dual-core processor from the latest AMD Ryzen 9 family. It uses the Zen4 architecture (Raphael) that AMD presented on August 29, 2022. For the first time since the introduction of AMD Ryzen processors, the Zen4 processors use a new socket, called AM5.This socket enables improved power supply and stability of the processors, especially under high load on multiple CPU cores. Together with the new manufacturing process (TSMC 5 nm FinFET), significantly higher clock frequencies are possible.
The AMD Ryzen 9 7900X has a base clock of up to 4.7 GHz. Up to 5.6 GHz under load on one core is possible via AMD Precision Boost 2 (turbo mode). With a load on all CPU cores, the clock rate is similarly high at up to 5.4 GHz and ensures a very high overall processor performance.
AMD is installing integrated RDNA-2 graphics in its desktop processors for the first time, but with two execution units it is quite slow. It is only used for image output and makes it possible to build a Zen 4 computer without a dedicated graphics card. This can be a significant relief in many areas.
The AMD Ryzen 9 7900X supports up to 128 GB of DDR5-5200 RAM. With the new Ryzen 7000 processors, AMD introduced EXPO technology, a new overclocking function for the main memory. For example, the use of DDR5-6000 memory should be easy and problem-free.
In addition to DDR5 memory, the new processors also support the interface version PCIe 5.0, which doubles the bandwidth compared to its predecessor. Depending on the motherboard chipset, 16 to 20 PCIe 5.0 lines are available to connect a dedicated graphics card or a fast PCIe 5.0 M.2 SSD.
The ISA extension AVX512 is also supported by the Ryzen 7000 processors.
