I am still using my I74790 which will run 3.8ghz across all cores and I have had it for quite a while now.

I was thinking of buying a whole new system at some point, I would be going all out though. I9-9900k RTX2080TI and 32gb ram.

But the more I read about the more faster and powerful cpus and their temperatures plus how they don't tend to run stable at 5ghz anyway the more I am thinking it would be a waste of money to buy a top of the range cpu.

Do you think that they will improve on cpus in the near future when it comes to temperatures? It seems that you have to delid them to be able to run a stable 5ghz without overheating and as soon as you do that the cpu's warranty is voided anyway.

And then there is the other thing of how some building games which I feel I should get a new system for still don't run very well even on a top of the range computer anyway.
 
I don't think 5ghz will come with cool temperatures any time soon, even with the next generation of CPU's.

You do however sound like you have a healthy budget so if that is your concern you could probably go for a pretty high end water cooling solution?
 
Ugh, well I don't like the fact of having water being circulated around inside my computer I just don't trust it but that's just me although with this type of system it seems to be the best way of keeping temperatures low although I have seen a video on the deepcool assassin 3 cooler.

My budget would probably be £3000 although I am not rich lol. Although I would probably only need to spend £2500. I don't plan in playing in 4k resolution either so the over kill of the gpu would be for future proof.

Why worry about 5Ghz? the 9700k or 9900k will run 4.6 to 4.7 all core boost (I've not checked). Difference between 4.7 and 5.0 is 6%... When are you really going to notice a 6% improvement. You have been running your current system without an overclockable CPU. I upgraded from a 4770k @ 4.4 to my current 8700k and it was a decent improvement in CPU bottlenecked games. Not a blow your socks off improvement but tangible, and I think its from a combination of clockspeed, IPC gains and switching from DDR3 to DDR4. The platform as a whole just has less bottlenecks that everything is that bit faster and smoother with more breathing room.

Ignoring increased IPC and memory speed gains going from your current CPU to one clocked at 4.7Ghz would be a near 24% improvement.

I understand what you are saying, it's not all about just the clock speed.
 
Aren't you forgetting craptacular price development of Intel?
Instead of giving genuine advance in cores&processing power per money Intel has been more interested on pumping butts of consumers... err prices.
And also lying in TDPs, which is grossly exceeded at advertised boost clocks in all core loads.

Anyway you better wait to June and release of Zen2 architecture Ryzens.
Those have bigger architectural/IPC improvement to current Ryzens than what Intel has had in half dozen years combined.
And instead of some originally designed for phone/tablet CPUs node, those come from TSMC's high performance node more modern than Intel's manufacturing tech.
In CES AMD demoed engineering sample matching 9900K's processing power at ~50W lower power consumption.
So release CPUs can well have even higher boost clocks.
And 8 core/16 thread model is likely just mainstream model, with 12 cores/24 threads becoming £300 level.
While 16c/32t monster is well possible into 9900K's price level.

That's more like where we should be, if PC Master Race hadn't turned into Intel Cash Cow Race.

5GHz all core will always be hot on any possible near future manufacturing tech.
While smaller nodes can lower power consumption, physical size of CPU cores producing that heat shrinks.
 
Do people really still use GHz as a measure of performance and assume linear scaling of frequency and performance? 5Ghz is just a number, it’s the difference in IPC and and improvement in efficiency that should be more important - the whole P4 debacle should have taught everyone that.

No need to be flippant, you should get that checked out. On a side note I doubt ghz should be ignored.

Personally I think now is a very exciting time for the CPU space, easily since the early core2duo/quad days - A friend at work just installed the 64 thread threadripper in a PC last week, and we have a new generation just around the corner.

The next few years will be very exciting indeed. I doubt you'll ever see cool, 5 GHz stable CPUs, but the IPC improvements and increased core count will make up for that in spades.

You seem very sensitive, are you OK? What you choose to perceive as flippant is amazement that someone would actually think GHz is a good metric for comparison in this day and age, it’s not usually indicative of performance and very rarely will performance in a given task and GHz scale in a linear manner. Use actual performance data in whatever task you use, GHz is largely meaningless. It’s like trying to compare engines based on rpm but ignoring everything else that’s actually important.

I'm fine you seem to be the one with pent up stress, definately some underlying issues going on there ;) how ever you try to twist it to suit your narrative and delusion. Only someone with a sound mind can see through your transparency. Its still possible to share your knowledge and opinions without having a flippant tone for what ever reason you feel the need to (well for people of sound mind at least anyway). I'm not saying that I disagree with you on the topic as you know a lot about it so it seems to somebody like me with my level of knowledge at least anyway.



Thank you to everyone elsws replies I appreciate it :)

I've unwatched the thread now as I'm happy enough with the answers. Have a good Easter weekend everyone!
 
Well I am running my i7 [email protected] with the same cooler that I used on my i5 2500K, the good old "Thermalright True Black 120" and I havent done anything to my cpu, just got windows nice and stable with the lowest voltages as possible with all cores running at 4.9ghz. The temps stay in the high 60's low 70's running "intel burn test" at max stress level and I upgraded just under a year ago from my i5 [email protected]

People overclock until the temperature reaches a comfortable limit. Years ago, 4GHz used to be the frequency everyone wanted, now it's 5GHz because cpus have improved so much.

If cpus improved even more so they run cool at 5GHz, then people would delid them to try and overclock them to 6GHz so they would be hot again. Then you'd be asking if they'll ever improve so they run cooler in the future.

CPUs have improved, so why not run it at a temperature you're happy with. Whether that's 4.3GHz, 4.5GHz or 4.7GHz.
 
400mhz extra on a CPU overclock is all I usually aim for, then hopefully I have a sensible voltage and reasonable temps. Rather have the CPU last as I don't change CPU's that often.
 
My 8700K will do 5GHz but it needs a lot of voltage and thus plenty of extra heat, even after delidding. I run it at 4.8GHz and the difference is indiscernible outside of benchmarks but the temps/noise are far lower thanks to the .15 lower voltage I need to run it at that. Still a 500MHz boost over the stock all core boost so I'm happy.

5GHz is a nice round figure hence some folk get caught up in trying to reach it.
 
Well he's not watching any more so clearly he enjoyed his Intel echo chamber. "5GHz is hot" "have to delid" "top-end CPUs aren't interesting". Well yeah, because Intel have been thoroughly uninteresting for a long time.

Zen however has been very exciting...
