Intel Microcode 0x129 Update increases the voltage and cpu temperature on my i5-13600K!
Posted by Stefan on 2024-09-09
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.
How to check if your Intel 13/14 gen cpu is affected by instability problems
Posted by Stefan on 2024-08-02
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.
AMD Ryzen 7000 and Intel Core i 13 Gen at almost 6 GHz clock speed
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.
Comparison of the two processors
The Intel Core i9-13900K and Intel Core i9-13900KF are very similar and identical except for the integrated graphics unit, which the Intel Core i9-13900KF lacks.Intel has been selling processors without integrated graphics since the 9th generation of the Intel Core i series. These are slightly cheaper in price. Since high-performance computers usually integrate a dedicated graphics card via the PCIe slot, they can then do without the iGPU. In the case of processors with iGPU, this is usually automatically deactivated by the mainboard if the mainboard recognizes a dedicated graphics card.
However, iGPU and dedicated graphics card can also be used together. To do this, the computer screen is connected to the iGPU and not to the graphics card. The image signal is then passed on to the graphics card from the iGPU/mainboard if required. The use of iGPU and graphics card can sometimes make sense, e.g. the dedicated graphics card can be put into sleep mode when the graphics load is low to save energy.
Like the Intel Core i9-13900KF, the Intel Core i9-13900K has 24 CPU cores that are built according to the big.LITTLE principle. 8 large "Raptor Cove" CPU cores (also called performance cores) are complemented by 16 smaller "Gracemont" efficiency cores. The different CPU cores can also work together on a larger computing task.
For processors with a hybrid core structure such as the Intel Core i9-13900K/Intel Core i9-13900KF, a modern operating system such as Windows 11 is recommended, since the operating system should specifically control the P cores or E cores in order to exploit the full potential of the processor .
Processors with a hybrid core structure are generally more energy-efficient than equally powerful processors with a normal core structure.
