3 years ago I took a good mother on the Z170 and a weak i3 6100 processor. Over time, I put top-end SSDs there, normal video, and went up to the processor. It suggested itself, as I planned, i7 7700K, I immediately calculated when buying a Z170 on tic-tac. But since the beginning of 2022, there have been rumors about Coffee Lake. First - that it will be with 6 cores. Then - that it will be with Socket 1151, as on my Z170 chipset. Then - that the form factor will be preserved, but there will be no compatibility with the 100-200 series. Then - what some manufacturers may have, they say, just ate the BIOS. Then - that there will be backward compatibility and only 4 cores will work on old chipsets. Etc.
Exhausted by rumors and my greed, a victim of marketers, by the summer of 2022 I began to understand that Coffee Lake would be, but not for my motherboard. I was terribly upset - so many hopes in the dust. And I remembered my student dream - the HEDT platform, which just received an ate that summer to the Kaby Lake level.
It turned out that a 6-core processor costs quite real money. Yes, mother is more expensive. But you don’t have to wait another 3 months for the release of Coffee Lake, and the upgrade possibilities are off the charts. You can even put 32 threads! No matter how much money, this motherboard will be able to master it :) In any case, in theory, the HEDT platform should be either the same or better than the mass analogue in everything? And so, on emotions, I bought this processor and a mother for it. Because 7800X is the cheapest for LGA2066 platform with 4-channel memory support.
Now 1 paragraph in fact. 7800X on MSI X299 GAMING M7 ACK board with CBO NZXT Kraken X52 works for me with fixed Vcore 12022V at 4.6GHz for all cores. RAM Corsair 4 to 8, 3200/16. Throttling moderately in benchmarks, I did not set AVX offsets. Allowable voltage for 7800X is up to 1.35V. That is, I could leave 4.8 GHz if I really wanted to.
Maybe someday I'll replace it with 7900/7920. But no more, see below why. And then, the kernels will double, and the price will triple. But rather, this expensive toy will go to the dustbin of history in this form.
