What justifies buying a skylake CPU vs a Hashwell CPU?

[pvtHenk]

So I was digging around a bit and comparing my i7-4790K with some other CPU's and found out that the i7-4790K is (in benchmarks) more powerful than the i7-6700K?

 

Price comparison (in euros):

i7-4790K (4.0Ghz ^ 4.4Ghz): 379.

i7-6700K (4.0Ghz ^ 4.2Ghz): 389.

 

Benchmark performance results:

 

And if we look at the performance per watt we can see that they both score 6.6.

So looking at these numbers we can assume that the i7-4790K scores quite a bit higher than the current consumer flagship i7-6700K. So if you have an i7-4790k already what would be the benefits of getting a new skylake processor? Seeing that DDR4 RAM is still at a slight premium price as well as skylake supporting motherboards? I'm not sure if the 6700K gets more overclocking headroom but I am currently running 4.6Ghz on my 4790K with a corsair H100i GTX AiO water cooler and sitting around 85-90 degrees on prime95 max heat test.

So again why would I spend more $$$ to get less performance?

Never use  ''CPU Boss''  as any form of intelligent information. The site is full of random data. If you already own Haswell CPU there is no need to upgrade.

It makes no sense to update from one gen to another, the performance difference is little, Skylake uses DDR4 as mainstream which has benefits, but for real to feel performance difference you should do like me go from a Core 2 Duo to the i7 6700 it's a true jump, go from Haswell to Skylake? hardly a step forward.

 

Also CPU Boss shows generic not too reliable benchmark results, you should really not use it and instead see like benchmark videos from respectable YouTube channels, Skylake IS superior to Haswell, you would not be paying for less, hell nah, however like stated it makes hardly sense to update this soon from an already good CPU.

Skylake IS faster, clock for clock. I'm not familiar with their scoring method, but if you look at the page, for whatever reason the Geekbench AES subscore is way down for Skylake, which probably skews their overall score.

Well it is just a compilation of benchmarks and it has the facts list at the bottom (which are most likely taken from the official intel specsheets). The point might not be entirely about upgrading my personal system but I've seen some friends of mine and people on this forum suggesting the a i7-6700K with their only argument being "It's newer". Newer does not necessarily mean that it's better right?

It does as long as you're comparing similar products due to better Lithography.

It's a compilation of rubbish. That's probably the most accurate description. You can't just put random data together to put a cohesive analysis on the product... Benchmarks is the only way of telling what cpu is better and which one is not. Cinebench is great for measuring rendering speed. Check proper websites about the new generation. Like Anandtech

Correct, but in this case, it is. Per clock, Skylake is faster than Haswell, and you get faster ram potential to help keep it fed. You could argue about overclocking but they're reaching similar clocks at the top end, and Skylake will still have faster ram to feed it.

 

The harder value case might be something like 6700k vs 5820k, but that is a more complicated comparison.

[paddy-stone]

The i7 6700k, should be better than the i7 4790k... but is NOT a justification for upgrading, there is probably around a 10% bump at best maybe. So it's not worth upgrading mobo/cpu/ram to get a 10% bump in any way.

This is a site that tells you the difference MUCH more accurately: http://cpu.userbenchmark.com/Compare/Intel-Core-i7-6700K-vs-Intel-Core-i7-4790K/3502vs2384

 

If you own an i7-4790K as others said, there is little to no reason to upgrade.

The justification to get Skylake is if you don't already have a board. If you've already a board for Haswell, or even Ivy/Sandy, just getting the best i7s will tend to do the job quite well. I hear even Xeons from the Nehalem Era (if you're lucky enough to have a 6 year old functioning board) are nothing to sneeze at either. 

 

I've been pondering an i7-4790K for my system as well. While my board will not overclock, 4 GHz base clocks with 4.4 GHz turbo sounds quite good. Keeping in mind that my board can force maximum turbo on all cores, I'm not missing a lot of the i7s benefits by forgoing the over clocking as most overclock don't go much higher. Plus, the chip actually runs hot enough where I can justify an aftermarket cooler.
