I would like to share my experiences with the latest Intel microcode update (0x129) with you. After updating to the latest BIOS version of my mainboard, not only was the latest microcode active, but the BIOS now has an Intel Baseline Profile, which sets or limits certain voltage and power supply settings in the BIOS. I compare the results with the older microcode 0x104, which still can also be set in the new BIOS.

Maybe you have heard of problems with Intels Raptor Lake CPUs (13/14 Gen Intel Core i) that have degradation problems due to high voltage and therefore can crash in some situations like gaming. We show you an easy way to check if your cpu is affected by using Intels own Processor Diagnostic Tool.

Posted by Stefan on 2022-08-29
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.

Intel Core i7-13700K could debut with 16 cores and 24 threads
Posted by Stefan on 2022-07-20
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.
