Hi All,

I currently have an i5-9600K paired with a 1080TI & 32GB DDR4 3000. I have been thinking about upgrading to the i5-12600K. I have a friend who is looking to buy my CPU, motherboard & RAM.

I would love to hear from any of you that have this CPU, from what I have read the single core performance is close to 45% faster than that of the 9600K which should yield a nice result in MSFS 2020. I plan on sticking with Asus motherboards and I am looking at the Asus Prime B660M-A (Although I'll gladly listen too any recommendations). At this point I am not sure a DDR5 board is worth it. Initially I plan on keeping the 1080TI and will see what happens this year with the 4 series cards and subsequent pricing of the 3 series. I was considering a 12GB RTX 3080 to go with this CPU. I exclusively use MSFS 2020 these days but still have X-Plane 11 although it has been a while since I flew in that.

Please feel free to share any thoughts on this choice of CPU/motherboard. 

I would love to hear them

Richard

 

TLDR: Wait until DDR5 comes down in price before going to high-end 12th gen intel. Graphics card replacement would see bigger performance improvements for a similar spend.

Very happy with my i5-12400F, coming from an i5-2500K with a big overclock. I considered the 12600K to start with but I decided it wasn't worth paying extra for the E cores and I can't be doing with overclocking faff these days. Also as I don't need the Win11 task scheduler (because I only have P cores) I can stick with Win10. I'm still getting that big single core performance jump over a 9th gen Intel, https://cpu.userbenchmark.com/Compare/Intel-Core-i5-12400F-vs-Intel-Core-i5-9600KF/4121vsm772658

I sacrificed 10-15% outright performance vs the 12600KF, but I saved £80 to spend on other components where I think I'll see more benefit. Until I upgrade my graphics card (running a GTX980 4GB still), the 12400F barely hits 35% running MFS anyway. You would see a lot more improvement upgrading your graphics card as I'd imagine that's where you are bottlenecked, although I am waiting until later this year when the 4000 series nVidia lands and prices become more sensible.

I would keep your DDR4 RAM for this build if you're doing it now, DDR5 isn't offering much improvement over good DDR4 yet plus the prices are still relatively high and availability is poor. Preferably, wait until late this year or early next year when more DDR5 is being made. There are also reports of some motherboards with higher end chipset needed to do overclocking having instability when XMP is enabled (there's a few threads at Avsim about it) which would be another reason to retain your existing RAM since it's towards the top end of the official DDR4 speed timings anyway.

PS: The non-K 12600 is completely different to the 12600K now. It use to be K was just a unlocked multiplier but for this processor the K die is different with more cores.

Some very good and valid points there,

GPU prices are still fairly high here in Canada but are going in the right direction, a 12GB 3080 is around $1,400 incl taxes which is almost double what I paid for my 1080TI. A lot more vendors are now carrying good stock of the RTX cards which will also force the used market down
