How much FPS gain?

[Lungzie94]

How much FPS will I gain going from an i5 4460 to an i7 6700k?

this is my current build

i5 4460
H81M+ Mobo
8GB DDR3 Ram
1TB HDD
GTX 1070 8GB
Corsair VS 450 PSU

TO

i7 6700k
Z170 Pro
16GB DDR4 3000mhz RAM
1TB HDD
GTX 1070 8GB
EVGA 750 Gold G2 PSU
Samsung EVO 750 250GB SSD

How much FPS would I expect to gain?

What games at what resolution and Hz? The answer varies from nothing at all to an big jump up depending on these points.

 

[Lungzie94]

AAA games, such as GTA V AC Syndicate Witcher 3, The Division, and 60hz 1080p

Hit up gameGPU and look up the benches yourself.

Witcher 3 is an example of an uncommonly well threaded game and benefits from the i7's extra threads.

Ex:

Basically, I want to know whether it's worth spending £700 to upgrade to get what 5-10 fps more, or go for a i7 4790k and spend the £200 saved on mobo and ram, on a GTX 1080 which will give 15-25fps more combimed with the I7

 

[Ecky]

The 4790K and 6700K perform about the same. You're looking at only a few percent difference. I wouldn't change sockets for that.

 

[Lungzie94]

So you think best idea would be to go i7 4790k and spend that £200 from mobo and ram, to get the GTX 1080?

Yes that would be much better decision, also pick up aftermarket cooler for 4790k cuz that CPU can get really hot with stock cooler.

 

[Lungzie94]

My problem with that is, it will be outdated within a year or so, and in actuality will cost the same as going for a full rebuild, but with much better mobo, ram cpu, etc just with a lesser GPU, which I can SLI at a later date.

 

[Ecky]

What will be outdated in a year? The 4790K performs essentially the same as the 6700K so in terms of which one will get "slow" first, it'll happen at the same time.

 

[Lungzie94]

I was referring to DDR3 1600MHz RAM and motherboard.

It won't be outdated. Note that on the chart @Ecky provided, the Sandy Bridge i7-2600K still managed to come out slightly ahead of the Haswell i5, despite its older architecture, because it had HyperThreading when the i5 didn't.

Plenty of other games released in the past year have shown the older Sandy Bridge & Ivy Bridge chips still able to keep up with the newer Haswell & Skylake chips -- DOOM (http://www.techspot.com/review/1173-doom-benchmarks/page5.html), Overwatch (http://www.techspot.com/review/1180-overwatch-benchmarks/page5.html), Titanfall 2 (http://www.techspot.com/review/1271-titanfall-2-pc-benchmarks/page3.html), Gears of War 4 (http://www.techspot.com/review/1263-gears-of-war-4-benchmarks/page4.html), Deus Ex: Mankind Divided (http://www.techspot.com/review/1235-deus-ex-mankind-divided-benchmarks/page5.html), Tom Clancy's The Division (http://www.techspot.com/review/1148-tom-clancys-the-division-benchmarks/page5.html), & Star Wars Battlefront (http://www.techspot.com/review/1096-star-wars-battlefront-benchmarks/page3.html) all show very close performance (not only between the older chips, but even between i5 & i7 chips), while even Rise of the Tomb Raider (http://www.techspot.com/review/1128-rise-of-the-tomb-raider-benchmarks/page5.html) & Fallout 4 (http://www.techspot.com/review/1089-fallout-4-benchmarks/page5.html) show the Haswell i7 chips keeping up handily with the Skylake i7s.

Bottom line, the number of games that can take advantage of the i7's HT advantage over an i5 are starting to increase, but the improvement is showing up across the board as opposed to just in the Skylake versions. Getting the GTX 1080 will absolutely raise your FPS, but getting a Haswell i7 for your build will also help provide better performance, & the two will provide much more of a boost than swapping for a Skylake CPU & motherboard.

 

[Lungzie94]

http://prnt.sc/d4okix which build would you rather have?

 

[Ecky]

Easily the 4790K. DDR4 has basically no practical advantage over DDR3, other than that it will likely be a little cheaper in the future as production continues to ramp up. Your motherboard will not affect performance at all, though I suppose you could justify spending an extra $500 if you feel it's worthwhile to get some USB 3.1 ports and an M.2 slot.

 

[Lungzie94]

Thanks, I'd like to get more views on this before I pick a solution though, if money wasn't an issue, which build would you go for? would like some more people to post their opinions please

 

[Ecky]

Even if money is not an issue, the 4790K + 1080 is a more capable gaming machine than the 6700K + 1070. A new motherboard has some nice goodies, but nothing that will in any way affect performance, unless you hope to extract 10-15% more out of the CPU with overclocking, which honestly is very little.

 

[Lungzie94]

I know what you're saying but, to me it just doesn't make sense buying a 2013 CPU when I can get the 2016 better version for the same price, it's pretty much buying a PC from 2014, I really want to upgrade to the best possible. But if what you're saying about mobo and ram not affecting performance, it's kinda limbo here

 

[Ecky]

This is basically the performance improvement you'll get by moving to Skylake, 3 years of progress:

 

[Lungzie94]

Woah, I read up about i7 4790k and i7 6700k, and I think I'll go with the i7 4790k actually, been an eye opener. But what about the i5 6600k? apprently it's on par with the i7 4790k but £100 less but according to those graphs it's not?

 

[Ecky]

It depends on what you're doing. i5's and i7's have the same single-threaded performance, but i7's have 4 more threads and ~30% more total throughput. A small but growing number of games, especially high-budget AAA titles, are capable of making good use of the i7's extra threads. Battlefield and The Witcher for instance run noticeably better on an i7 than an i5. However, an i5 is often considered the better value.

 

[Lungzie94]

Alright thanks, you think this build is solid?

i7 4790k
H81M+
16GB DDR3 1600Mhz RAM
EVGA 650W Gold PSU
GTX 1080
1TB HDD
250GB SSD

 

[Ecky]

That'll be fine. You may want an aftermarker cooler, the 4790K is one of the only Intel CPUs in recent memory that may actually throttle with the cooler Intel provided with it. Something like a ~$25 Hyper212 would be more than adequate.

 

[Lungzie94]

Tbh "fine" isn't good enough haha, I want to build a solid PC that will play AAA games for atleast 2 years on max settings.

 

[Ecky]

You're already at the top of the food chain with both CPU and GPU, there's not much else you can do that will have any meaningful impact in games. The only feature I'd miss is an M.2 slot and a nice NVMe SSD, but again, this will have zero impact on your framerates.

 

[Lungzie94]

I'm not PC savvy, what are M.2 slots and NVMe SSD?
