Core i7 7700k Confirmed Benchmarks- Zero IPC gains over Skylake

PCGamesen and Hardware Unboxed just released their reviews of the 7700k, and it has confirmed what most of us already knew: that Kaby Lake offers zero IPC boosts over Skylake. None, not even 1%. They ran both processors at 4.5ghz, and ran multiple tests, only to come to that very same conclusion:

Quote

As the name suggests, the 7700K is another K-series variant, which means it has an unlocked multiplier and, given the optimised process, we ought to hope the overclocking performance of the Kaby Lake generation has been boosted.

 

In reality though we're just getting a processor which maintains the previous generation’s dominance but is incapable of really pushing things any further.

As I said though, there are some slight tweaks. The main one being the change in base and Turbo clockspeeds. Out of the box the Core i7 7700K comes with a 4.2GHz base and 4.5GHz Turbo frequency. This is a function of Kaby Lake being an optimised version of the Skylake architecture’s 14nm design. Twelve months after then inaugural Skylake release Intel have been able to wring a little more performance out of the silicon with only a little extra energy required using small changes in the production process, now called 14nm+.

My thoughts on this? Well, I've been preaching this very same information on the forum for a few months now. We saw no reason to believe any IPC boosts back then, and now we have our confirmation. While it's disappointing for Desktop users (especially those that own Skylake chips already) it is still pretty exciting for mobile users. The more intelligent Turbo Boost will likely aid in battery life, and higher clocked SKU's with the same TDP envelope is always welcomed on platforms that traditionally do not allow overclocking. At the very least, we can look forward to Skylake-E with AVX512 on the horizon.

Anandtech ran them at 3 GHz and found the same. No IPC improvement.

 

What I find striking (aside from the K-series i3 that is) is the pricing model: Anandtech lists the i7-7700K for $305, i5-7600K for $217, and i3-7350K for just $157. All of those prices are well below the ~$260/$360 we usually see for unlocked i5's and i7's, and the i3-7350K is not drastically more expensive than previous i3's. Though obviously there's no way to know if they will actually be available for those prices any time soon.

I'll add that PCPer seems to be reporting about the same prices that Skylake launched for, so I'm not sure where Anandtech picked up that $305 figure for the 7700K.

To be fair, it's not like we were expecting any. Intel didn't state that Kaby Lake had any IPC gains over Skylake; only clock speed boosts due to a better 14nm process.

Inb4 @patrickjp93 has some nonsensical and stupid response that comes out to roughly "Working as intended. Intel 12/10."

 

Or the usual "It's the software. I'm a master coder, I can fix everything that everybody has done. Especially the people with drastically more knowledge and experience than I actually posses."

I know, I mentioned that in the post as well. Some very select people were making claims of 3-6%, but realistically, nobody believed them. This is only to serve as a confirmation to those that were still in doubt, or were worried about buying Skylake.

Yeah, by the looks of it the difference is ~.2 ghz or so when overclocked. So 7700k is about 5% faster than the 6700k. Not really that impressive, honestly.

Higher power efficiency allows greater overclocking. And greater battery life in the mobile world.

No, I am not defending Intel. I am just saying the fact of reality. Maybe Intel is smart in that they are taking advantage of the lack of competition, to address the design issue of their CPU in being so power hungry.

Even then, that's not a complete guarantee. The article I linked was able to get their chip to boot at 5ghz (my 6700k can boot 5ghz as well) but was not even remotely close to being stable. 

 

Quote

But if you were hoping, like me, the performance optimisations would lead to a CPU generation more than happy to boost over the 5GHz mark for larks then you’ll be disappointed. I’ve only been able to complete a full benchmark run at 4.9GHz, just 100MHz higher than the Skylake i7. Inevitably that’s not going to translate to any meaningful performance lead. 

 

I did manage to get the 7700K booting at over 5GHz, but it was by no means stable. I could run relatively CPU-light workloads at that speed, such as games, and even managed a few runs of Cinebench, but the aggressive X264 v5 benchmark kept making the system fall over. It didn’t seem to matter how much extra voltage I gave the system, it couldn’t get through a full run. 

 

The other issue is that with the extra voltage temperatures go through the roof, even with a closed-loop water cooler whirring away atop it. I had to shut down the X264 v5 test when I started upping the CPU voltage because my 7700K was running up to 100°C. Even in the stable 4.9GHz configuration it was peaking at 92°C which just feels too high to be run like that as normal.

Now, 4.9ghz isn't bad, but he also didn't take the time to stress test or validate it's stability. He openly admits to using it only in the benchmarks, which I have seen 4.9ghz 6700k's do the same. If we take in the average 6700k's on OCN, their average OC is 4.7ghz with a sample size of 92: http://www.overclock.net/t/1570313/skylake-overclocking-guide-with-statistics

 

We don't have enough Kaby chips to speak with absolute certainty, but I assume it will fall somewhere around that mark, maybe slightly higher. Either way, I wouldn't stress buying Kaby over Skylake if you can get Skylake cheaper. If you already have a Skylake i3 or i5, and are wanting to upgrade, sure, a 7700k will work just fine, just don't expect it to outperform an equally clocked 6700k (not referring to you, just speaking in general now).

KBL was a fab process improvement with more powerful integrated graphics.  The desktop market has been "good enough" for a few generations now so the aim is at mobile.  If you really care about desktop performance that much they want to move you to the 2011 platform.

 

BTW internal benchmarks are at 5-9% improvement over SKL across the SKU stack, but that's based on the clocks being faster for the most part.

The overclocking part is kinda hit or miss from what I can tell from reviews (once you throw volts at Kaby, it seems to get out of control and lose any gains in efficiency), but the battery life aspect is a big deal. In the reviews we have seen from Mobile Kaby Lake, the advanced Turbo Boost is really paying off in that regard, and that alone is very exciting. I touched upon that slightly in the original post:

Lmao I already seen 6 people say they're upgrading their 4770ks or 4790ks. I've seen another 4 ask about upgrading their 6700k. Get ready boys, the used market is going to be fun.

It's uses 3W less at idle then a 6700k and 3W more at load so it evens out. Wouldn't consider this any better. The only thing Laby Lake has going for it is higher OCing and some minimal features that are very user specific.
