Kaby Lake i5 or i7?

[Tacos4all]

So let's keep this strictly to Kaby lake alright guys? I know sometimes we tend to say "well last gen is just as good." But for the sake of this thread, 7th gen Kaby lake only.

i5-7600k or i7-7700k?

The only differences I see between the two are:
Clock speed i7 +400MHz Base, +300MHz boost
Cache: i5 6MB, i7 8MB
And the oh so elusive to the i5 line, Hyperthreading.

Honestly it is like Intel is charging $100 for the Hyperthreading.

In modern gaming, at say 1440p 144Hz, which is going to deliver the real-world performance to match the buck? How many games really utilize hyper threading besides something like BF4/1? (neither of which I am interested in).

Here's a couple hypothetical builds (close to what i will be building) and on UserBenchmark, they are pretty much identical. (Z270 boards are not yet on Userbenchmark, so I chose a popular one one that would support the new chips, not settled on what mobo to buy yet)
 

Userbenchmark PC Build Comparison
Baseline Bench: Game 112%, Desk 100%, Work 79%
CPU: Intel Core i7-7700K $350
GPU: Nvidia GTX 1070 $380
SSD: OCZ AMD Radeon R7 480GB $195
HDD: Seagate Barracuda 7200.14 2TB $52
RAM: Corsair Vengeance LPX DDR4 2400 C14 2x8GB $100
MBD: Asus Z170 PRO GAMING $153
Total: $1,230

Alternative Bench: Game 110%, Desk 97%, Work 64%
CPU: Intel Core i5-7600K $243
GPU: Nvidia GTX 1070 $380
SSD: OCZ AMD Radeon R7 480GB $195
HDD: Seagate Barracuda 7200.14 2TB $52
RAM: Corsair Vengeance LPX DDR4 2400 C14 2x8GB $100
MBD: Asus Z170 PRO GAMING $153

I'd get the i7

 

as a side note: avoid AMD's SSDs, their TRIM implementation is seriously fucked up: https://www.pcper.com/reviews/Storage/Samsung-750-EVO-Full-Capacity-Roundup-Planar-Performance/Performance-Comparisons-TRI

 

it takes 3sec / GB when deleting a file

Spoiler

and 0.7sec / GB when TRIMing the whole partition - that's slightly more than 5 and ¹/₂ minutes total

Spoiler

What is the point of this?

Why would you buy OCZ if HyperX Savage MLC 480Gb costs less?!

To all asking about the SSD's. I already have them in my system. They were gifted to me by a friend (didn't specify but I have two of them RAIDed together). So I will just migrate them to the next build as they already have windows installed and i can easily re-activate with Windows 10. the Seagate Barracuda is also a part from my current system.

As stated above, I'd get the i7. I say this as a person regretting not getting a 2600K instead of a 2500K. And yes, you're pretty much paying for hyper threading,

Alright thanks. I guess the hype behind hyperthreading is worth it. This is from a 4 year i5-3570k user so I suppose it is time to step on up.

Personally I'd get the i7 too. (Because future proofing)

For gaming the i5 should be more than enough.

Even a previous generation i5 would be enough to game on for a few years.

Get the i7, comes in handy in games that are CPU demanding. The ASRock boards offer a little better value at that price point, but if you like the looks of the ASUS no worries.

Yeah i will probably go with an Extreme4. I have an Asrock z77 Extreme3 right now and have never had any problems. Plenty of options and great overclocking capabilities for the price. I just put the Asus in because it was one of the few Z170's that are capable of running Kaby Lake right now. And there aren't any Z270's on UserBenchmark. Thanks for the feedback.

Yeah I am using an i5-3570k OC'd to 4.2 right now. Still performs really well. This is not something I plan on building super soon. I first am gonna get a GIGABYTE GTX 1070 G1 Gaming and just slap that on my current build and see if the CPU bottlenecks it. If it doesn't then I will hold off on getting a new Cpu/Mobo

I have a 2500K and a 1070, 4.6GHz on the CPU and 2.1GHz on the GPU. I don't game much (Mostly 3D Model / Unity engine work), but the 2500K does keep pace with it for the most part. It really depends on the games though, some are more CPU heavy / badly optimized.
