i5 vs i7 for 144hz gaming

Hey guys, was just wondering if anyone has any good articles for cpu bottlenecking at 144hz gaming. Most of the benchmarks I find are rigs with gpu bottlenecks like 1 GTX 980 Ti or something. But I'd like to see benchmarks for 980 Ti sli or 1080 sli with an i5 6600k to see if its enough for 144hz.

 

purely for gaming the difference would be minimal (unless your into RTS even then a lot of games won't use all cores) also as usawell with sli overclock the cpu will give you the best proformace boost

please read through the intro at the top of the artical

Interesting. I know there are a bunch of cpu intensive games (like Arma 3, Star Citizen, and even Crisis 3) that I thought an i7 would benefit a bit over the i5 from higher clockspeeds and hyperthreading.

 

As i said above there are a few that will take advantage of the extra but as ever we are limited by the console (xbox/sony) developed games (Used RTS as an example in post above), it depends what you mostly play & what else you will be using the computer for if a i7 is worth it or not. also i would be concerned (nVidia cards) about pcie lane speed as long as you have both at at least 8x as they don't use it all, I'd expect it to more likely make a difference to AMD GPUs as they carry the crossfire information over the pcie lanes but I've not see any test on that yet or the new pascal cards.

even then saying that there are fair few professional programs that don't support hyper-threading & few that will make use of all cores , there are even som cad programs that dont use GPU aceleration

look into what you play/use the most & build a system around what it supports

 

This is more for a friend who is either going to do 980 Ti sli or a 1070. As you can see in my sig I have use for an i7 and have powerful gpus but I just wanted to know what kind of impact on high end intensive games the cpu has. I play at 4k so I don't really get high enough frame rates to encounter cpu bottlenecking. So I mean Witcher 3, Crisis 3, Star Citizen, Battlefield 1 etc... Not really RTS for the most part as that's not his thing.

 

I cant see it making any difference to the performance of sli (i5 vs i7) just as ever OC the CPU its not worth buying a k series if you don't

performance drop in these games CPU wise I'd expect to be about 5 FPS with

there is quite a performance jump up from 1070 to 980ti sli, personally id suggest the i5 with sli but that is just my opinion

 

A 1070 is about on par with a 980 Ti (or a Titan X, depending on the program/game), but the 1070 is a lot cheaper.

If you can get an i7 for close to the cost of an i5 (say within $100) I'd get the i7, assuming your budget can handle it. But definitely splurge more on a better GPU. An extra $100 spent on a better GPU will get you a lot more FPS than going from an i5 to an i7.

As such, definitely get a 1070 instead of a Titan X/980 Ti. Price/performance wise the new Pascal GPUs are miles better than Maxwell cards.

One of the reasons the i5-6600k is so popular is that most people are on a fixed budget, and the $100 extra cost of the i7 isn't worth it compared to pumping an extra $100 into a better GPU, or a better/larger SSD, or more/faster RAM, or a better monitor.

But the i7 is a better chip and will provide better performance in almost all games. It's just that for the majority of the games the increase is barely noticeable.

 

No no, for 400 bucks he can get 980 Ti sli or a 1070. The 980 Ti sli is most likely what he would do with that power obviously, but its possible the deal he may get on them won't work out.

 

That doesn't make sense, given the current MSRPs, but if he can indeed pull it off, good for him. Are they used 980 Tis?

 

Yessir. It's basically a friend with specs similar to mine is willing to give him a great price on them when he upgrades to Pascal cards.

 

I've learned that it's always best to get the superior hardware if it is within your budget, especially if there are any worries of the i5 creating bottlenecks.
Buy the best that you can afford now. It'll save you money in the long-run and you won't need to upgrade as frequently.

TLDR; get the i7.

 

is that X99 build, in your sig, what u're using now? if so, then u have a solid gaming system.

if not, then an i5 would definitely bottleneck SLI 980 Ti's.

 

I totaly agree with this. Absolutely no need to downgrade from your current CPU.

 

Again this isnt for me, and yeah I saved for a long time to get that rig. Its for 4k gaming. I'd lean towards the i7.

Not my rig I'm talking about definitely not downgrading.

 

Oh my bad, must have misread.

 

Guys just remember as you turn up the resolution you are less CPU bound so say a I5 might suffice but at 1080p 144hz you probable want the I7 to prevent the bottleneck in general....
