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 The latter were manufactured using an outdated manufacturing process and could not keep up with the competing products from Intel.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

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.

According to an internal Intel slide published at the end of last year, the Intel Core i7-13700K could have 8+8, i.e. 16 CPU cores that provide 24 threads. The interesting thing about the slide is that it was recently confirmed by newer leaks of the Intel Core i9-13900K and the Intel Core i5-13600K as the number of cores and also the size of the cache matches with recently published CPU-Z screenshots of alleged development models.

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.

Comparison of the two processors

In a comparison between the Intel Core i9-13900K and the AMD Ryzen 9 7950X, the current top models from the two manufacturers compete against each other. The technical implementation of the two processors could hardly be any different.

The Intel Core i9-13900K relies on a hybrid big.LITTLE CPU core structure consisting of 8 fast P cores (performance, Raptor Cove) and 16 smaller and more efficient E cores (efficiency, Gracemont). The P-cores have a base clock of 3.0 GHz and can reach up to 5.8 GHz in turbo mode. These cores are based on Intel's older CPU cores of the Intel Core i generations.

The smaller E cores are based on Intel's Atom technology and clock at 2.2 GHz. These smaller CPU cores also have a turbo mode in which a clock frequency of up to 4.3 GHz can be achieved. Although the smaller CPU cores are slower than the faster P cores, they require significantly less energy. The E cores can take care of background tasks to save energy or calculate tasks together with the faster P cores.

In total, the Intel Core i9-13900K has 24 CPU cores that can process up to 32 threads simultaneously.

The AMD Ryzen 9 7950X relies on 16 equally sized CPU cores that clock at 4.5 GHz in the base. The AMD processor also has a turbo mode and can reach up to 5.7 GHz as long as the power consumption and CPU temperature are within a specified range.

The classic CPU core structure of the AMD Ryzen 9 7950X seems increasingly outdated, as it does not act as dynamically and flexibly as a hybrid core structure and, for example, requires significantly more energy than a hybrid solution when idling or with low CPU loads. It is expected that AMD will follow the competition with the 8000 generation (Zen 5) and also offer CPUs with a hybrid core structure.
