CPU: 10700K
Motherboard: Z490 Aorus Pro AX

I generally don't build a new system often, typically only every several years when my current system is just simply too old to even be reasonably upgraded to run even decently with current software, so I am not too familiar with differences between a single CPU generation.

In fact, if my current 3770K system had not died on me, I would still be running that as it was still more than adequate for my gaming uses, even if it was starting to suffer from virtualized systems. And if it wasn't for the fact that I needed to replace it quick and the only parts I could get reasonably and at a cheap price were a 10700K for less than a 5600X and a z490 board for cheaper than an AMD equivalent and needed Intel RAID support to recover some data I would have just gone AMD.

But regardless, I have a 10700K system right now, and I am going to likely be stuck with it for many years, but my motherboard apparently has some enhancements that will only work if I install an 11th gen CPU in it. It supports PCIe 4.0 and will enable that for some of it's current PCIe 3.0 ports, as well as enable a currently disabled 3rd m.2 NVME port that will operate in 4.0 unlike the current ones that operate in 3.0. So the main reason I want a 11700K is not for performance over my 10700K, but to get PCie 4.0 support.

I know that for now 4.0 isn't much of a difference over 3.0, but as I said, I will be stuck with this system for years, and it could very well be a more important factor later on (both for GPUs and if DirectStorage starts to matter later on), so I just wanted to make sure what my options would be in the future.

I know that the 11900K is more or less a downgrade from the 10900K in just about every way except for PCIe 4.0, but from my understanding the 11700K wasn't hit as badly compared to the 10700K right?

What I want to know is, if I were to replace my 10700K with a 11700K, would it perform worse in any way? In terms of single-core/threaded performance, multi-core performance, hyperthreading, thermals, etc? I am ok with it performing the same as my 10700K since as I said, the main reason I want it is for PCIe 4.0 support, but I don't want it to perform even worse than my current 10700K or run hotter..... since when running a CPU torture test with AVX enabled my current 10700K already came very close to thermal throttling. (I had heard that some games are starting to implement AVX now, so I don't think it's as ignorable as it used to be, temps are fine when I turn AVX off).

And as mentioned, since I am not too familiar with single-gen CPU upgrades, how likely is it that a microcode update could in any way improve the 11700K? Has there ever been a decent improvement in performance or thermals from a microcode update? Or is it almost never much of a difference and I should not even bother considering that a possibility? (I know that there were several small microcode updates around launch, no idea how common that is or if I should bother to expect any more.... especially ones that do anything noticeable)

Now, granted, I am not going to be rushing out and getting a 11700K anytime soon. I will likely do this within about a year if it's feasible for me to do so. I just wanted to know if there would be any reason for me not to upgrade from a 10700K to a 11700K if my main reason was to get PCIe 4.0 support and I am fine with it performing the same as my 10700K just as long as it doesn't in any way perform any worse?

Its more of a side grade than an upgrade so unless you really need PCI-E gen 4 dont bother you might as well skip Intel gen 11 and gen 12 as well since DDR5 is going to be worse than DDR4 to begin with

Keep your 10700K its good enough you have already spent money on it so why spend more

People that want to get RL are only doing so because they like to tweak and overclock. It has better memory controller.

AVX-512 is also a valid reason.

OP, I guess if you are really going to keep it that long it wouldnt be bad, I personally dont think it is worth the ~$150ish price delta for just pcie4 support, I actually just returned (an already open box) 11700K because it really didn’t seem much better than anything else I already have/have had.

Which for reference has been a lot! I’ve had and returned: 10700(k), 10400, 5800X, 2700X, 7800X, 7940X and aside from the 2700X, I couldn’t really tell the difference between any of em [5700XT and 2080ti, so possibly gpu limited]).

If that money spent on an 11700K could be saved and used to make upgrading everything happen a little sooner, that would probably be better than getting a new cpu anytime soon (not that I have any business telling someone not to upgrade, when I feel like I change things up multiple times a year).

what about a 5820k to a 11700k
Honestly, I’d consider a 6950X too. At least it would be a drop in replacement and you could get a little more out of your whole platform.

Edit: There really are no bad choices out there as far as upgrades go, just go with whatever you feel comfortable with (be that price or perf based). Imo the best thing a 5800x has over a 10700k/11700k is the upgrade path to a 5900x/5950x (buuuuut, since you still seem to be rocking a 5820k on your X99 board, you may hold on to the 5800x long enough that something newer/shinier catches your eye and that benefit becomes irrelevant).

Full disclaimer, I’m biased against Zen3 a bit (and RKL quite a bit). Didn’t like the price hike/lack of cheaper options. Like a 10600K was like 92% of the perf and 72% of the cost of a 5600X on release and now its like 66% of the cost. I think I just upgrade too frequently to care about the fact that I could have gone with 5800x now and dropped in a 5900x later (I mean,

I owned a 5800x briefly and then sold it within a month).
Had the price to performance been better, I’d have kept it, but after getting a 2700x when the 3700x series released for like $120ish after tax at microcenter on Black Friday, it’s hard to spend ~quadruple that on another 8c/16t cpu no matter how much better is (and it wasn’t twice as good). At ~$330/350 before tax, I’d love the 5800x. At $430+, I still like the performance, I just hate the price. The 11700k and lower aren't awful value propositions, but them reducing the 10 series prices are really the best thing about them imo. 11900k doesn’t exist to me (200+ over the 11700k for ????).
