Hi, while I am searching for memory for my system, I noticed that Z390 motherboards only support dual channel but can remain stable with faster RAM at 4000. Together with i9-9900K, will such system be faster than X299 system with quad channels RAM of 3200? What are the advantageous of going for Z390 and 9900K? I think the i9-9900K is as hot as the 7900X but the latter has more PCI lanes.
 
Solution
The 9900k is faster in practically everything, regardless that the 7900x has quad channel memory architecture. The gains of quad channel do not even come close to the gains in clock speed and IPC on the 9900k, and that's without factoring in the potential for an overclock.

If you look at the comparisons between the 8700k and 7740x here, it's probably at least marginally comparative considering that for most things you are not going to see more than 8 threads being used by any one application or game anyhow. In fact, I don't know of any that can utilize more than that, although certainly multitasking with...
Memory prices are supposed to continue to drop according to some sources, and that's possible because Intel has been unable to meet the supply demands for their processors which means there is a glut of Nand and memory chip surplus, but I've heard that before. Right now memory is almost as cheap as it was two years ago, which was as low as I can recall it being in recent memory.

If you don't need the parts now, you might wait until after the new year begins, but that's your call. Don't say I said to wait and then prices go up. LOL.

Thanks. I am a bit worry that everything will become more expensive from Jan 1 due to the traiff.
