P cores are slower than their predecessors?

Of the upcoming Arrow Lake desktop models, the Core Ultra 9 285K is likely to be the fastest model to begin with. In addition to the Skymont E-cores, the CPU also features Lion Cove-type P-cores that are said to reach 5.7GHz at a boost speed. There’s still some ambiguity when it comes to the question of how many cores are generating the boost. But it seems that all eight cores only manage 5.4GHz and perhaps one or two cores will reach the aforementioned 5.7GHz. So the E-cores should achieve a boost of 4.7 or 4.6GHz.

The comparison with its predecessor is interesting: the Core i9-14900K will be 300 MHz faster in the P-cores and 300 MHz slower in the E-cores. We should also not forget that Hyper Threading will no longer be available – at least that's what rumors have been saying for some time. So the Core Ultra 9 285K is a 24C/24T (8 + 16) configuration.

Above this CPU, a KS model is expected, which will then go to 6GHz or maybe a little more with a thermal boost. However, the TVB window is very small and requires good cooling. Intel will no longer offer F models. Instead, every Arrow Lake CPU will have a Xe-LPG IGP with 4 processing cores. OC will again only be possible on Z890 motherboards. According to rumors, the first six Core Ultra 200 processors won’t appear until December – about half a year after the new Ryzen 9000.
