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.

Last week we already reported on the new Intel Core i7-13700K processor from Intel, which is expected in autumn 2022. With 8+8 CPU cores (24 threads), the Intel Core i7-13700K should have the same configuration as last year's Intel Core i9-12900K. With this, Intel wants to finally clear AMD's lead in multi-core performance, which has existed for several years.

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 two processors from this comparison are models with 12 physical processor cores each. However, there is a clear difference between the models here, because the Intel Core i7-12700K from the 12th generation of the Core i7 processors initially relies on a big.LITTLE structure that has long been known from the ARM processors. In this case, this means that the 12 cores of the Intel Core i7-12700K are divided into 8 high-performance cores and 4 energy-saving cores. Only the 8 high-performance cores support hyperthreading technology, which means that the processor has a maximum of 20 threads available. The AMD Ryzen 9 5900X, on the other hand, continues to rely on a normal processor structure with 12 identical high-performance cores and 24 threads.

The maximum clock frequency of the Intel Core i7-12700K is 5.00 gigahertz and the AMD Ryzen 9 5900X is 4.80 gigahertz. According to our benchmarks, the Intel Core i7-12700K is a bit faster in the single-core benchmarks, but due to the higher number of high-performance cores, the AMD Ryzen 9 5900X catches up in the multi-core benchmarks and is roughly on par with the Intel processor.

The Intel Core i7-12700K has an internal graphics unit called Intel UHD Graphics 770. This iGPU has 32 execution units and 256 shaders and achieves an FP32 processing power of 742 gigaflops. With the AMD Ryzen 9 5900X, as with all processors of the AMD Ryzen 9 series, you have to do without an internal graphics unit and instead have to use a dedicated graphics card.

The Intel Core i7-12700K came on the market in the fourth quarter of 2021, making it almost exactly 1 year younger than the AMD Ryzen 9 5900X, which was launched in the fourth quarter of 2020. Despite the younger age, the Intel Core i7-12700K is still manufactured in the 10 nanometer process, whereas the AMD Ryzen 9 5900X is already manufactured in 7 nanometers.
