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.

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 The latter were manufactured using an outdated manufacturing process and could not keep up with the competing products from Intel.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.

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

In the CPU comparison between the AMD Ryzen 9 5950X and the AMD Ryzen 9 3950X, the newer AMD Ryzen 9 5950X can set itself apart from its direct predecessor (Zen 2 Basis) with an almost 20 percent increase in raw performance per clock (IPC). In addition, AMD was able to slightly increase the turbo clock frequencies, which in turn helps the AMD Ryzen 9 5950X to achieve a small increase in performance.

Both processors are equipped with 16 cores, which can process up to 32 threads simultaneously by using SMT. This makes the high-end processors particularly suitable for video editing or other intensive calculations. In a game PC, the processors are also very fast, but usually cannot fully utilize their high number of cores.

The AMD Ryzen 9 5950X is based on the Zen 3 CPU core design, which AMD presented on October 8, 2020. Larger cache changes and the reduction in the number of internally combined modules led to the largest IPC jump since Zen 1. All processors (Ryzen 3xxx, 4xxG and 5xxx) are already manufactured in a modern 7 nm process at TSMC and are therefore very efficient. AMD specifies an efficiency that is superior to the Intel 10th Gen desktop processors (such as the Intel Core i9-10900K) by a factor of 2.8.

Both processors can address a maximum of 128 GB of DDR4-3200 RAM via a maximum of two memory channels. The maximum memory bandwidth is around 60 gigabytes per second using both memory channels. In order to be able to use the dual-channel mode, at least two working memory modules are required.

All Ryzen 3xxx and 5xxx processors do not have an internal graphics (iGPU) and are therefore dependent on a dedicated graphics card. Intel usually builds an iGPU into its mainstream processors to reduce the dependency on a dedicated graphics card, although most gaming PCs naturally have a dedicated GPU.
