4790k vs 7700k at 1440p

[leelaa14]

So my 4690k is bottlenecking my 1080 at 1440p. Granted not in all games, but in quite a few.
I made a post a while ago asking the same thing and seemed set on the 7700k, my decision was based on benchmarks I had watched. Later though i noticed these tests was at 1080p. I understand why they was done at 1080p but it doesn't really give me an answer to my problem.
Will the 4790k be enough to get rid of the bottleneck and last me some years? I get the 7700k beats it in raw performance, but as long as that bottleneck is removed and my gpu is running to it's full potential and I still have some head room, then I'm fine with that.

4790k will be fine, don't forget to overclock it. Also I would try to find it on used market,might get a killed deal

Yeah I'm looking on ebay and seeing them go for about £250-£280 which I'm fine with. Can just drop it in my PC.

Be careful with buying unlocked processors used, as the seller could have totally ruined them with high voltages. Find a seller with lots of good feedback or at least someone claiming it's never been OC'd.

 

Either way I agree, go with a 4790K. There's a minimal performance difference and you'll need a new motherboard to swap to the 7700K.

4790k vs 7700k is too small an upgrade to justify the new mobo and RAM.  If you want a brand new CPU get coffe/cannon lake in a few years, or conversely r7/r5.

[pelark]

Get the 4790k.

I'd also recommend that you consider dropping in an extra 8gb kit of corsair ram in your rig, unless you feel there is no need.

Yeah was intending on going to 16gb too.

I went from an i5-4570 to a 4770k a few months ago. Got it on ebay for fairly cheap, OC'd it to 4.3 and couldn't be happier.

I lucked out and nabbed a 4790k on eBay a few months ago that had never been OC'd. Definitely a worthwhile upgrade from my 4670k without breaking the bank for a whole new platform.

[leelaa14]

Thanks for all the replies. Def gonna go with the 4790k.

Unless you already have mobo for the 4790k I would just drop some cash for the Ryzen 1600x

Ryzen from what I've seen really isn't much better than my 4690k in gaming.

I can't read today thought I read a 3690k not a 4. I just mixed up a 780 Ti and a &50 Ti.

[IceCold008]

i have a 4770k stock speed at 1440p and its my GTX 1080TI which is the bottleneck which is what you want happening.

 

This means that my GPU is using 100% of its power. That is what you want, your new shiny little GPU to do. Why buy a GPU for example like a GTX 1080TI if your only getting for example like 50% of its full potential. So for example. It costs you 700 pounds, but you have wasted 350 pounds of that lol get my drift

 Ya the conventional wisdom until a few years ago was that anything more than an i5 is wasted on gaming.

That is very untrue now as games have become multithreaded.

My i7 3770k is way better than the i5 3570k now, wasn't the case when i bought it.

[lieder1987]

I have a 4790k (not overclocked) and a 1080 running at 1440p and I am not getting any bottlenecking at all. Just in case that helps.

Not only that, but GPUs have gotten so fast that anything less than an i7 can't keep up feeding instructions to the high-end stuff (1070+).

I guess it's the fact that GPU perf is now advancing so much faster than CPU perf (which has started to plateau).

The resolution has no impact on CPU usage.  That's all GPU.

 

If you're planning on changing motherboards, I'd recommend the 6700K.  Both Haswell and Kaby Lake have heat problems.  You can't get a decent overclock without delidding and removing the adhesive, which is obviously risky.

The Haswell heat problems aren't that bad. The 4770K was known to run particularly hot, yet mine runs passively 90% of the time on an air cooler (no fans running) @4.3GHz. Not a crazy OC, but decent. 

 

All depends on what you want, I guess. The performance difference from Haswell to Sky/Kaby Lake just isn't worth the high cost of the upgrade, IMO. To upgrade to a Haswell i7, it's just the cost of the CPU, minus how ever much they are able to sell the old i5 for. To jump to Kaby Lake, it's the extra cost and hassle of changing motherboard, ram and CPU, which you cannot re-coupe as much of the cost by selling the old hardware.

Well my 4790K won't go past 4.5GHz.  That's only 0.1GHz past the Turbo Boost speed.  Despite having a huge air cooler (Cryorig R1 Ultimate), the fans have to run pretty loud.  I've considered delidding, but I'm honestly worried I'll break it.  Plus it took me well over an hour to install that cooler (I did it the wrong way first ).

 

But I was never recommending upgrading past the 4790K.  I was just saying that if the OP did decide to upgrade to a new generation, Skylake might be a better option.

Ah that's right, the 4790K has a higher boost clock than the 4770K. That's why they call it the silicon lottery. I know someone who can barely get 4.0GHz from their 4770K. My system was stable for a while at 4.4, then I had to dial it back to 4.3 after a couple BSoD's while gaming. 

 

I'm honestly surprised how cool my 4770K remains with this OC and passively cooled with the voltage at 1.325. I do have it set up for the CPU fan to come on when it gets over 50*C, but it will only ramp up to about 50% max. so it stays nice and quiet. Highest temps I've observed were in the mid-high 70's. Still well within safe limits. Perhaps that's a testament to how well the Lucifer V2 cooler works. I've been quite impressed with it, especially since it's only a $50 cooler.

My point was that you got lucky.  There is a reason Haswell (and now Kaby Lake) benefits more from delidding.  You probably know this (it doesn't seem to be common knowledge though), but the thermal paste is fine.  It doesn't perform as well as something like Arctic Silver, but it also lasts way longer.  The reason delidding is really beneficial (and why it wasn't in Linus's video) is because the problem lies with the adhesive.  Removing all the extra adhesive (Haswell and Kaby Lake tend to have more of it) so that the IHS sits right on top of the die is what gives all the extra performance.  Here's a diagram:

 

I've seen a lot of delidding tutorials where the instructors thought it was because of the thermal paste.  In reality, it mostly depends on how much extra adhesive was used to hold down the IHS.

I'm sorry... if you have a 1080ti at and a 4770k at stock speeds and are bottlenecked at 1440p it isn't the GPU that's causing that.

Its the GPU which is causing that and its what you want to happen every system has a bottleneck when it comes to gaming. You want your GPU to bottleneck lol. And i no what a bottleneck is and what too look for. lol.
