Is the Intel Core i7 6700 the same as i7 4790k in performance?

[Wrath]

Cant decide which should i upgrade to, please help me decide.

get the 6700k or 4790k and z board
either would be better than 6700 (non k), 4790k can easily overclock more than 10% in a z board

skylake it is about 10% faster per clock vs haswell/refresh
power draw is slightly more than haswell/refresh, 91w vs 88w

i7-6700 is weaker than i7-4790k.

i7-6700k is stronger though. (And more expensive)

Cant get my hands on the i7-6700k where i live for now :(

The 4790k is a better deal anyway. The CPU itself is cheaper and you can get a mid range motherboard for the price of a low end Skylake motherboard. I would just get the unlocked Haswell over anything Skylake.

was thinking of getting the msi gaming 5 motherboard what do you think ?

With the MSI Gaming 5 and the Gigabyte Gaming 5 you get the best for the money.

It's not just a matter of CPU comparison, you have the motherboard generations too.

A Intel Skylake (6th Gen) is approx 10% faster overall compared to the Haswell (4th Gen). If you already have the Haswell, it's not really worth the upgrade just for gaming purposes however. If you had a Sandy Bridge, it would be well worth the upgrade for features.

Depending on the motherboard, Skylakes extras would be...
USB 3.1 - Extremely faster USB port(s)
SATA Ports - Faster
Bus Controller - Faster across the motherboard
SLI - More support and higher bandwidth
DDR4 - Double bandwidth, currently loose CP timing however which will likely improve more in the future. Currently well overpriced too, compared to how much it costs to make.
Power management - Ideal power savings for laptops

Saying that, would you use those? Depending on the pricetag - For gaming purposes the i7 4790k is still a great pick and not bottlenecked. It's DDR3 memory will slowly be discontinued however.

i have the i5 3570k for almost 4 years now its been a great CPU for games but im feeling its been struggling lately in games like the witcher 3 and GTA , kind of in a dilemma between upgrading to DDR4 memory CPU or the i7 4790k, i have a good graphics card(GTX 980) and i owe to it a better CPU.

The i5-3570k (Ivy Bridge - 3rd Gen) got superseded by the Core i5-4670K (Haswell - 4th Gen).
Compared to the i7-6700K, you would be looking at least 38% overall performance gain.

What is your root purpose for the system? Just gaming or also applications/editing, etc?

Power Draw - in most situations, the i7 6700K uses about 4-10 less watts than the i7 4790K.

Temperature - Depending on what you are doing, the i7 6700K should run about 4-7 ºC cooler than the i7-4790K.

Performance - In most cases, the performance of the i7 6700K compared to the i7 4790K was either identical or significantly better.

For gaming purposes, it won't make too much difference. 25% faster with onboard graphics, however gaming would use a discrete GPU, so that doesn't matter anyways. You would just be looking at a few FPS difference. Depending on the pricetag, is that worth it?

It's not until you do other things, such as there's a 15% increase in performance when exporting images on Intel Skylake vs Haswell. In PhotoShop, you could expect a 16.7% performance increase, etc.

As for DDR4 vs DDR3 - Games don't care. Calculate the overall real-world performance levels by a calculation of balance ( CL / MHz x 1000 = ).

For example (lower value is actually faster)...

DDR3:
CL 9 / 1600MHz x 1000 = 5.6ms
CL 9 / 1866MHz x 1000 = 4.82ms

DDR4:
CL 15 / 2400MHz x 1000 = 6.2ms
CL 16 / 3200MHz x 1000 = 5ms

You will notice what I meant about loose CL timing on DDR4 currently. This will however tighten over time.

A GTX 980 won't be bottlenecked on either system.

Thanks for your tips I've decided to go with the i7 6700k ,and yes my purpose for the system is only gaming no streaming no nothing just was to play games at maximum setting and enjoy decent fps.

Just keep what you got maybe upgrade other components. Will be a waste of money for gaming as an i5 performs as good as an i7 in games IMO. I have 4th gen i5 and an i7.

going to wait for fallout 4 to release if there isnt any problems on maximum settings i wont upgrade, thanks for your advice as well

i5 3570k definitely doesn't need to be upgraded. It will still not bottleneck any modern games and any money spent on a new CPU would be better spent upgrading the graphics instead.

I've bought my GTX 980, 7 months ago friend won't upgrade it for some time,I've started thinking of upgrading cause of the recent games demanding an i7 for max settings.
