Artificial Intelligence and Machine Learning

Processors with the support of artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors. Algorithms for ML improve their performance the more data they have collected via software. ML tasks can be processed up to 10,000 times faster than with a classic processor.

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 The latter were manufactured using an outdated manufacturing process and could not keep up with the competing products from Intel.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

A direct comparison between the Intel Core i7-11700K and the AMD Ryzen 7 5800X only makes it clear how close the two competitors AMD and Intel are currently. In the case of the Intel Core i7-11700K, Intel was able to significantly increase the raw performance per clock, but has not yet reached the IPC that AMD achieves with Zen 3 technology. Therefore, Intel gave the Intel Core i7-11700K a 300 to 400 MHz higher clock to catch up with the AMD Ryzen 7 5800X.

The Intel Core i7-11700K does this quite well. The 8-core processor is only slightly behind the AMD Ryzen 7 5800X in benchmarks. Intel's new Rocket Lake architecture is used in the Intel Core i7-11700K, which is actually a backport from 10 nm to 14 nm. Intel is still plagued by production problems in 10 nm manufacturing. Since Zen 2, AMD no longer relies on in-house production at Globalfoundries, but now has its processors manufactured by TSMC in Taiwan. The Zen 3 processors are manufactured in 7 nm, but TSMC already has a 5 nm node, which, however, has been completely reserved by Apple. Only AMD's Zen 4 processors are also manufactured at TSMC in 5 nm.

Since both processors have 8 CPU cores and support Hyper-Threading or Simultaneous Multi-Threading, 16 threads can be processed in parallel by the CPUs. Intel is limited to 8 cores at Rocket Lake, while AMD has significantly larger expansion levels on offer with the AMD Ryzen 9 5900X (12 cores, 24 threads) and the AMD Ryzen 9 5950X (16 cores, 32 threads).

The rivals are also very similar when it comes to RAM: 128 GB DDR4-3200 memory in two memory channels (max. 4 modules) are supported. Due to the smaller manufacturing density, AMD can give the AMD Ryzen 7 5800X 32 MB Level 3 cache, while the Intel Core i7-11700K has to get by with 16 MB.
