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.

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.

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.

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.
