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.

Mobile chips you need to look at.

lmao we both know patrick will throw all of that out the window because those aren't his sources.

Hey, I'll add whatever sources he has too. All relevant information is important, as long as we can extrapolate a widely accepted conclusion from all of it. Hopefully we get more information about overclocking, as the sources I have only touched upon it (rushing the review to be first, I assume). I'll look deeper into it as the day goes on, maybe we can get more information sooner, rather than later.

Ikr I just might get that 6700k I was looking for

CPUs don't really devalue much especially the top SKUs within the last 2 gens.  You can pretty much sell a 4790K now for the same it was going for a couple years ago.

I wouldn't hold my breath on getting sources from patrick but more info is definitely needed

It's more of a running joke than hate.... Who doesn't make a joke at some one's expense ? Especially when they're the one who keeps digging the hole for themselves

I don't hate him. He's just really condescending and has an over-inflated sense of self importance.

[Djole123]

Wow... I'm dissapointed. But I also have to say that's not entirely unexpected. You see, they made the three year cycle: Process, Architecture, Optimization. Process=Broadwell, Arch=Skylake and Kaby Lake is Optimiziation. So it's not unexpected they won't bring anything major to the table.

 

They could've certiandly done better tho. I really hope that Summit Ridge pushes Intel a bit.

[NumLock21]

Even thought there is zero IPC between Skylake and Kaby Lake. Kaby Lake is still a good upgrade for those who have at least a 5+ year old system. They get new technology that was not available with their old one, like USB 3.1, type C, NVMe, DDR4, Sata Exress, Optane with Z270, and M.2.  The will be a IPC improvement from Kaby Lake compared to your 5+ year old system vs those who already have Skylake.

It was to be expected, it's why I didn't bother waiting and just grabbed a 6700K back in November. No regrets.

Lower 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.

 

 

 

I think you mean better power efficiency, or higher power efficiency. Lower would be using more power lol

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.

What's a good place to stake out?

Do you mean lower power usage? Because lower power efficiency means it uses more power.

7400k? Is that a cheaper alternative or just a new name for the x600k top i5 chips?

I hope prices for the xeon 1231 v3 go down even more I'll probably get one soon.

Yeah the only reason to go with the new hardware is if you need one of the new technologies and somehow can't use an add-in card or if you're on super outdated hardware like I am.

That's not a new architecture as far as I'm aware.

No IPC gains, but it seems like initial reviewers are easily breaking into the 5 GHz + range at 1.3x volts with minimal tweaking and AIO cooling.  Even without IPC improvements, if max average overclocks go up, the chip is definitely worth looking at.  It appears that they improved the silicon so the Skylake 4.6 to 4.7 average may become a Kaby Lake 5.0 to 5.1 average.

 

In addition to that, 4k encoding/transcoding seems to have received a substantial boost.

Only ones that are moaning are those who are constantly upgrading for the sake of having something new, even when it offers no improvement from what they currently have. Because of this, these people start to spread misinformation according to their personal setup, and then you have those who believe in it. Which is one of the reason, there are those 6700K vs 7700K topics.

I know you used the word "may", implying that it may or may not be true, but to clarify for others: It's way too early to take the overclocks obtained in these benchmarks as the expected average. Kaby Lake (and specific Z270 boards) brought a new feature, which is an AVX multiplier. Many reviewers are using this new feature to claim stability in certain benchmarks that would otherwise be unstable due to extreme heat (Prime95, Aida64, XTU/Linpack, etc). While I won't discount 5/5.1ghz as being impressive, it's simply far too early to expect that to be the average. We already have one reviewer claiming 4.8ghz as his max stable overclock, with 4.9ghz being unstable (even after being able to boot 5ghz).

Overclocking
Overclocking perceptions will change with Kaby Lake, due to the new AVX Offset feature to be found in the BIOS of each Z270 motherboard. AVX instructions are known to cripple a good overclock, reducing the stability and making it harder to push the non-AVX code if that is the limitation. With Kaby Lake, a user can apply an AVX offset (e.g. -10x) which will reduce the multiplier when an AVX instruction occurs. This means that if an overclock of 4.8 GHz is reached and an AVX Offset of 8x is in play, then the AVX instruction will run at 4.0 GHz, generating less heat and keeping the system stable.

We will have a dedicated overclocking piece going over all our OC results, but the short of it is that all three of our K-SKUs (retail parts) happily reached 4.8 GHz AVX at a reasonable voltage. The i7-7700K was able to hit 4.9 GHz with an AVX offset of -10, and our i5-7600K hit 5.0 GHz even with AVX turned on.

As for the source on the reviewer that failed to go beyond 4.8: http://techreport.com/review/31179/intel-core-i7-7700k-kaby-lake-cpu-reviewed/14

Quote

After several cycles of increasing multipliers, running Prime95, and increasing voltages as needed to achieve stability, we ended up at 4.8 GHz and around a 1.32V Vcore. Our system could boot at 4.9 GHz, but we ran into thermal throttling when we tried increasing the Vcore further to achieve stability. Considering the i7-7700K's 4.5 GHz stock Turbo speed, a 6% overclock ain't much—especially when it's threatening to overcome a $110, 280-mm liquid cooler.

It's still to be seen whether or not the 5ghz clock speeds from these reviewers were a result of selective binning, this new AVX multiplier option, or more mature silicon. We will likely find out once Kaby hits retail. Either way, if they do in fact clock higher, @Lays will be one happy man.

Agreed that at this point I'm only speculating based on unknown specifics of those reviewers hitting 5+ GHz.

 

With regards to the source that couldn't go beyond 4.8 GHz.  He did mention that he was potentially thermally limited with his cooling solution so it's hard to say whether or not the chip could have gone further.

The AVX Offset has been a pretty big hit with Broadwell-E.  While it is a bit of a cheat, it definitively allows a user to capitalize on tweaking for higher clock rates under lower type load conditions.  It still has a benefit as seen in the BWE community.

 

@Lays sucks.  He rides a moped.
