new i7 9700k for 190USD or new i9-9900(non K) for 220 USD or keep waiting for 10 Series or Zen 3

Been itching for an upgrade for a bit now since my i7-930 started showing its age when I tried playing some games in 3D Vision and they need more single core performance. Some 3D vision games like GTA V and GTA IV have a bug that limits the processing to 3 cores and so demands higher single core peform to get more juice outta my card. Right now my card in 3DV when rendring open world situations in those games uses only 20% of my GPU. This problem dissappears indoors in these bugged games

Anyways, my Intel store finally have a k processor available. I already snagged the non K a while back and have been sitting on it, unopened waiting for a K version to show up. I was actually hoping the 10 series would show up by now or a 9900k on the cheap but neither has happned. After 2 years of being at Intel, this is actually the only time I've seen a mainstream K version processor show up. So I am giving it till at least Zen 3 to see. While I wait, I am wondering if I should do any thing about this 9700k or wait to see if something liek a10 series or 9900k pops up

We are only limited to 2 buys a year and I've already used 1 on the 9900 not knowing when something decent will show up again.

Keep in mind the 9900 can boost up to 4.7Ghz on all cores

I'd just keep the 9900 you already have. If you already have a Z board, why don't you adjust the BCLK to something like 102 and lengthen the turbo limits. You'd probably get pretty close to 5Ghz.

Even with your particular limitation, I don't really see there being a huge difference between say 4.9 with hyperthreading and 5.0-5.1 without.

So i have been out of the OC/CPU world for a long time now. Like 10 years long. What is this you're talking about lengthening turbo limits? Are you trying to tell me there is a way to boost non K CPUs past their rated all core turbo freq? kirbyrj

Download the Intel Extreme Tuning Utility.

Under "Advanced Tuning" and then the "Core" submenu, look at the "Reference Clock." Bump this to 102.

Also under the "Core" menu, look at the "Turbo Boost Power Max" and "Turbo Boost Short Power Max." Set these higher. For example, I have mine set to 225W, but it's cooler dependent, etc.

Finally, under the "Turbo Boost Power Time Limit," max that out to 128 Seconds.

So what does this do? You'll get a higher single core and all core boost by about 100 Mhz due to the higher "Reference Clock"/BCLK. It will power throttle less because you are extending the turbo boost to 128 Seconds rather than the stock, and the limit of what the turbo will do is raised to essentially the maximum of the CPU.

I've had pretty good luck with that setup on a 10700 (non-k), which is essentially the same as what you have. Plus, I can always drop it down to 65W stock configuration as needed.

I'm sure I'll PM you at some point if I do build this thing. But what if I want it to be boosted to the max at all time? And if that is not temp efficient, how can I ensure it boosts to that and stays there when I am playing a game or doing something demanding. To me it sounds like this boost thing ccomes and goes? kirbyrj

Also 9900 apparently states:
Turbo Frequency
5,000 MHz (1 core)
5,000 MHz (2 cores)
4,900 MHz (3 cores)
4,800 MHz (4 cores)
4,800 MHz (5 cores)
4,700 MHz (6 cores)
4,700 MHz (7 cores)
4,600 MHz (8 cores)

But it seems you're assuming that it can go up to 4.9 boost with your trick

I was going by your 4.8Ghz comment earlier. You'll gain about 50 Mhz for every 1 BCLK you raise. So maybe only 4.7Ghz then with all 8 cores (up to 5.1 with up to 2 cores?). The best thing I can tell you to do is download the Extreme Tuning Utility and then see what it looks like at stock and then change the values I noted above and see if it makes a difference. The boosting "coming and going" comes down to the power limits set in the boost and the duration of the boost. By doing what I mentioned above, you change both the short and long turbo boosts to a higher power draw allowing it to not "come and go." Then changing the duration allows it to boost longer also (not as important if your short and long turbo power are the same).

What kind of boosts do you get out of your 10700? kirbyrj
Btw, I do not have any Z boards. I haven't opened my 9900 because of what I said in the OP. I do not have any modern systems. I am still on my X58 platform from 2010
