The Intel Core i9-9900KS processor has revealed an increase in the base frequency and TDP
The ability of the Core i9-9900KS processor, which will be released in October, to maintain the activity of all eight cores at a frequency of 5.0 GHz was known initially, but it is still silent about other characteristics. However, already at the end of August, motherboard manufacturers began to introduce support for the new processor at the BIOS level, and the appearance of references to the Core i9-9900KS in the lists of supported products on their sites allowed us to study some interesting changes at the level of characteristics.

In particular, on the ASUS website, the Core i9-9900KS processor showed its base frequency, which increased from 3.6 to 4.0 GHz, when compared with other models with the same numerical index. When looking at the TDP value, it becomes clear that it was this increase that allowed us to raise the base frequency of the processor. The TDP ceiling rose from 95 to 127 watts. In fact, this allowed not only to guarantee the processor at a frequency of 5.0 GHz with the activity of all eight cores, but also to raise the lower frequency bar. By the way, the Core i9-9900KS processor itself is based on the same R0 stepping of Coffee Lake Refresh crystals, which was released back in May with the aim of fixing current security vulnerabilities.

The Coffee Lake Refresh crystal plays an important role in another aspect. the 14-nm process technology determined a sufficiently large area of the crystal, and therefore the heat flux density is not so high, and it will be possible to cool the Core i9-9900KS processor not only with unattended liquid-type systems, but also large radiators with efficient fans, of which there are enough on the market. Problems with motherboards due to an increase in TDP should also not arise, since their power subsystems are calculated with a large margin, if we talk about flagship models.
