i5 2500k (4.7Ghz) vs i5 6600k (3.9Ghz). Looks like Sandy is still up there but difference in ipc is starting to show, maybe even worth an upgrade if you planing an high overclock on Skylake. All in all, is it stock 6600k enough for gaming this days? I would say yes.

Too pricey, i got i7 2600 for 100$, so no, thanks, still it's nice to have little speed boost.

I wasn't being inconsistent I just quoted the wrong section.
Haswell being Tock.
Page 2 first paragraph
I wasn't being inconsistent I just quoted the wrong section.
22 nm product yet based on a FinFET process that uses a non-planar transistor that sits around the gate on three sides. Built using a 22 nm process, Haswell is the "tick" in Intel's "tick-tock" development cycle, so Ivy Bridge was just a process size shrink from Sandy Bridge's 32 nm to 22 nm.

I could have missed it in the review but Skylake offers hardware support for DX12 feature level 12_1 --- offering support for ROV, ConservativeRasterization, TiledResources and ResourceBinding all at Tier 3.

Page 15, just below the second image it says...
There aren't any benches on that page running medium settings. The first says "ultra" and the second "ultimate". The last one is firestrike.

With this GPU and medium image quality settings we won't be GPU bound, and this displays CPU and mainboard performance difference really well when something changes in the system.

Also are those TDP figures accurate? I thought (4x90k) have a tdp of 88W?
I wish there were more i5 reviews to show comparisons between the generations though, otherwise this just looks like it's a platform update bringing DDR4, what happened to PCI-e gen 4 though? I thought that was to be expected in skylake.
It's rather a disappointing release so far.

I will stay with 2500k unless mobo or cpu dies, not worth the upgrade yet.

Since DX12 is the next big thing, I wouldn't buy quad core CPU without hyper-threading.

Not a real cores, not helpful. I would start thinking about real 6-8cores CPU's in the future.
As you can see, 6600k beats your 3770k in every game.

Why isn't there a 4670K or 4690K in the benchmarks?

DX12 will benefit all CPU's.
This is the only thing I could find showing synthetic performance differences between an i5 and i7 with HT on. i5 is clocked slightly higher.

Titan X loves this CPU, the difference is amazing!

Indeed. Great performance on i5 6600k. Just like i said, its beating past gen i7's. Overclocking makes alot of difference though, you'll need 4.5+Ghz Sandy and Ivy to match stock Skylake performance.

Things could end the other way around because with dx12 devs won´t need to dedicate a core to api overhead anymore, dual cores might catch a second wind.

DX12 should take advantage of the extra threads.

It would be nice if in this review was also included i5 4670K. I guess that H.H couldn't find a -good- chip from them. (?)

When you consider that the progression is actually Sandy -->Ivy -->Haswell -->Haswell Refresh-->Broadwell -->Skylake...
You can kind of see why Intel effectively scrapped Broadwell! I know it's not scrapped, read effectively! It was meant to be a full release remember.

Its about Intel HD Graphics 530 (Skylake),not about the cpu(fpu) itself.So if you wanna play DX12 games with iGpu you got it.
Still i7 4790K is better and you dont need to change mobo. Till DDR4 CL9 will come well will be long time. Till then HBM will become standard on our computers.
And when Intel will give us an i7 without iGpu and with 8 cores,or i5 with 6cores??? (i dont want it 5820k)

Yeah, I would have liked to see a comparison of these as well, but perhaps H. doesn't have a sample of them on hand. My graphics card is never represented in the graphics card reviews either. I have to approximate its performance from the 660Ti and the 680. But, again, I'm sure the omission is due to the unavailability of the specific hardware.

It's actually quite possible for them to do so, but then the LGA2011 platform would become redundant. Also, if they did they'd charge like a wounded bull for it no doubt.
AMD are looking to do just that with the Zen, have either 4 core APU or just 8 CPU cores. The 8 CPU cores looks to be a real 'monster', however for gaming the 4-core APU may be 'better' if the load balancing suggested rumour between discrete and APU is true. I believe that's possible under DirectX 12, but will likely to be not utilised much. I'm talking about a rumoured AMD implementation of it which will work in any game.

Indeed, never knew overclocking could make this much of an difference.
At least i don't notice ANY increase when i OC mine so i left it stock for now.
EDIT: Should be quiet an upgrade for me lol: http://www.anandtech.com/bench/product/108?vs=1544
Double the speed of my i7.

How so?, even with "to the metal access" core code of games is something that hardly scales up to two cores, dx12 threaded draw calls see like 15% improvements beyond four cores, and the "next gen" cpu physics that some devs thought would kill four core cpu in game ports (under dx11 where one core was dedicated to api overhead) vanished in the air after console specs were released. Also it seems that multi-platform games wont get considerably more processor hungry any time soon because stuff like AC unity and project cars are known to be already severely cpu limited on consoles (Same with the witcher 3 where game devs have had a hard time doing world streaming with their humorous processor).

Nice review HH! Guess i might keep my i5 2500k for now and upgrade when i do full system re-build.
