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.

The evolution of AMD Ryzen processors
Posted by Stefan on 2022-09-06
The AMD Ryzen processors are designed for the mid to high-end range and are grouped into the Ryzen 3, Ryzen 5, Ryzen 7 and Ryzen 9 classes. AMD follows the market leader Intel, which groups its Core i series (Intel Core i3, Core i5, Core i7 and Core i9) identically.
The AMD Ryzen processors were first introduced by AMD in Q1 2017. They are the successor to the not particularly successful AMD Bulldozer processors. The latter were manufactured using an outdated manufacturing process and could not keep up with the competing products from Intel. AMD lost a large portion of its desktop processor market share during this period.

AMD Ryzen 5 7600X and AMD Ryzen 7 7800X are coming in September
Posted by Stefan on 2022-06-20
After we published a performance assessment of the AMD Ryzen 9 7950X last week, the well-known AMD leaker Greymon55 has now posted more informations via Twitter.
He predicts the first four models of the new Zen 4 desktop generation, which AMD would like to present at the end of 2022. There is also an alleged release date of September 15, 2022.

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 !

Comparison of the two processors
AMD Ryzen 9 5950X has 16 CPU cores and can process up to 32 threads in parallel using simultaneous multi-threading. The desktop processor is AMD's largest expansion stage for the mainstream socket AM4. The clock frequency is 3.4 GHz, but the AMD Ryzen 9 5950X can increase the clock frequency up to 4.2 GHz (utilization of all CPU cores) or even 4.9 GHz in single-core operation.The Intel Core i9-11900K clocks its 8 CPU cores with 3.5 GHz in the base, but can also adjust its clock frequency dynamically. In turbo mode, 4.8 GHz are possible when all cores are loaded or even a very high 5.3 GHz when only one CPU core is loaded. The i9 also benefits from Hyper-Threading and can therefore process 16 threads in parallel.
Both processors have a free multiplier and can therefore be overclocked. The AMD Ryzen 9 5950X also has a 64 MB level 3 cache, while Intel has given the Intel Core i9-11900K only 16 MB. The maximum amount of RAM on both systems is 128 GB, with both processors being approved for DDR4-3200. With overclocking, significantly higher clock frequencies of the main memory are possible on both systems, DDR4-3600 is actually always achievable.
Despite its 16 cores, the AMD Ryzen 9 5950X has a lower TDP of 105 watts than Intel's Core i9-11900K, which is specified as 125 watts. This is mainly due to the significantly better energy efficiency of the AMD processor. Its "Zen 3" CPU cores are already being produced in a modern 7 nm process, while Intel is still using a (greatly improved) 14 nm production process. The "Rocket Lake" processors, to which the Intel Core i9-11900K belongs, were originally supposed to be manufactured in 10 nm. Due to delivery bottlenecks, Intel had to port this architecture to 14 nm via backport.
