Why the new AMD Ryzen 7000 processors for the AM5 socket are currently not a good deal
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.

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.

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.

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

The AMD Ryzen 9 5900X was released in the fourth quarter of 2020 and comes from the fourth generation of the AMD Ryzen 9 family. It is manufactured with a structure width of 7 nanometers and is based on the Vermeer (Zen 3) architecture. The processor is designed for socket AM4 and supports AMD-V and SVM virtualization technologies. The AMD Ryzen 9 7900X is 2 years newer. It was launched in the fourth quarter of 2022 and is part of the sixth generation of AMD's Ryzen 9 family. It is already produced using the smaller 5-nanometer process and is based on the Raphael (Zen 4) architecture. It is designed for the new AM5 socket and supports the same virtualization technologies.

Both processors are each equipped with 12 processor cores and support hyperthreading technology, which theoretically means they have up to 24 computing threads available. The AMD Ryzen 9 5900X has a base clock of 3.70 gigahertz and the maximum turbo clock is 3.70 gigahertz. The AMD Ryzen 9 7900X has significantly higher clock frequencies, the base clock is already 4.70 gigahertz and the maximum turbo clock is also significantly higher at 5.60. In addition, both processors can also be overclocked, but this requires appropriately good cooling of the processors.

An internal graphics unit is only integrated in the AMD Ryzen 9 7900X. The ninth generation AMD Radeon Graphics is installed here, which is based on the Raphael architecture. It is equipped with 2 execution units and 128 shaders and the maximum tubro clock is 2.20 gigahertz. The AMD Ryzen 9 5900X can only be operated with a dedicated graphics card. There are 20 PCIe lines available for this purpose. Of course, the AMD Ryzen 9 7900X can also be operated with a dedicated graphics card; it even has 24 PCIe lines.

Both processors can be operated with up to 128 gigabytes of RAM. The AMD Ryzen 9 5900X supports DDR4 RAM, while the AMD Ryzen 9 7900X already supports DDR5 memory.
