Intel Core i9-14900K: The most powerful for desktop

Test setup

The top model of the 14th generation of Intel Core (Raptor Lake Refresh-S) processors has outperformed everything that has come out for desktop computers so far. In speed, but also in power draw. On the one hand, the 6 GHz metric for single-threaded applications has been reached and the clock speeds are very high even under all-core boost, the side effect is that the Core i9-14900K’s power draw can sometimes spike up to 400 W.

Test setup

* We use the following BIOSes on motherboards. For Asus ROG Strix Z790-E Gaming WiFi v0502 – Intel Raptor Lake/v1501 – Intel Raptor Lake Refresh, MSI MEG X670E Ace v1.10NPRP, for MEG X570 Ace v1E, for MEG Z690 Unify v10, for MAG Z690 Tomahawk WiFi DDR4 v11, for MEG Z590 Ace v1.14 and for MEG Z490 Ace v17.

Note: The graphics drivers we use are Nvidia GeForce 466.77 and the Windows 10 OS build is 19045 at the time of testing.

Processors of other platforms are tested on MSI MEG Z690 Unify, MAG Z490 Tomahawk WiFi DDR4, Z590 Ace and Z490 Ace motherboards, MEG Z690 Unify (all Intel) and MEG X570 Ace, MEG X670E Ace (AMD).

On platforms supporting DDR5 memory, we use two different sets of modules. For more powerful processors with an “X” (AMD) or “K” (Intel) in the name, we use the faster G.Skill Trident Z5 Neo memory (2×16 GB, 6000 MHz/CL30). In the case of cheaper processors (without X or K at the end of the name), the slower Kingston Fury Beast modules (2×16 GB, 5200 MHz/CL40). But this is more or less just symbolic, the bandwidth is very high for both kits, it is not a bottleneck, and the difference in processor performance is very small, practically negligible, across the differently fast memory kits.
