Anyway, I don't know why it matters whether Intel is getting the performance thru more frequency or higher perf/MHz. All that matters is delivered performance.
Right, and if the base is 4.2 with a 4.5 turbo, I may not even bother overclocking much or at all. My 2600K is fine, but I've got the urge to upgrade and I have a sinking feeling that I will be disappointed in SKL-X - disappointed that I had to wait that long for what will likely be really high prices and similar performance to the 7700k at 4-6 threads. I really thought BW-E was the ticket but was super disappointed in performance, overclocking, and especially pricing.

I also know that KBL is built off the SKL core, but your own quote from Intel states they're seeing performance increases. Now, whether that is solely due to clock increase or not I'm not sure, but whatever the case may be, I don't think it makes sense for me to go with a 6700K unless there is a huge cost savings over the 7700k. My next rig will probably be another 5 year rig and may even be the last I build. It has been hard to get excited about Intel silicon the last few years, so humor me guys. :D

Mobile Kaby Lake was already benched at notebookreview. No IPC increase. Not that there was any doubt, since Intel said the same. There is no core changes. Its a Skylake refresh on 14nm+ and with the video decoder improved.
Fair enough. I know about the video decoder improvements, but do most modern (NV 900 series+) incorporate a similar decoder in their cards? I haven't kept up with that news, but let's say a 1x00 series GeForce has a similar or better decoder - it might make sense to stick with a 6700K and just upgrade my video card. Not only would I get the video decoding capability, but performance increases in other areas.

All ASUS LGA1151 motherboards now support Intel's next-gen Kaby Lake CPUs





ASUS has announced that all of their existing LGA1151 motherboards now support Intel's next generation of Kaby Lake CPUs thanks to a collection of new BIOS updates.

This means that all ASUS motherboard using the Z170, H170, B150 and H110 chipsets will support Intel's Kaby Lake CPUs, across all of ASUS' different brands from ROG to Pro Gaming all the way down to ASUS's more affordable motherboard designs.

All of ASUS' 100-series motherboards support ASUS USB BIOS flashback, allowing end users to easily update their BIOS files.

First MSI, now ASUS. :)


PCWorld's Intel Kaby Lake Review: What optimization can do for a 14nm CPU

...Fortunately, I had access to three generations of Dell’s excellent XPS 13. They’re not identical, of course, but they’re close enough that the comparison has some validity. I purposely selected tests that would minimize those differences.

The newest XPS 13 costs $1,100. It’s equipped with a 7th-gen Kaby Lake Core i5-7200U, 8GB of LPDDR/1866 in dual-channel mode; a 1920x1080, non-touch, IPS panel; and a 256GB Lite-On NVME M.2 SSD.








You know Kaby Lake’s magic on the CPU side is mostly a clock speed bump. Graphics? Another bump. The big upgrade is to the video engine, where Intel added a wealth of hardware support for such things as VP9 at 4K resolution and 10-bit color support for HEVC.

To find out the practical upshot I used an Intel-supplied 10-bit HEVC file at 4K resolution. The file was actually the same open-source Tears of Steel video, but encoded at a 10-bit color depth.

Only the 200 series mobo will have support for Intel Optane right? That and the 4 extra pci lanes is the reason I want to switch from a z170 to a z270.

What extra lanes?

Optane is just running of NVME. But lets be honest, datacenters are going to take all 3dxpoint production until 2018.

Kaby Lake has 300 MHz more than Skylake (+10,7%).
In Cinebench, Kaby Lake score is 320 and Skylake score is 286 (+11,9%).
IPC difference is very tiny.

People don't know or care about IPC. They care about how fast jobs get done, and how fast the computer "feels". If KL can stay at higher freqs longer, then it will handily beat Haswell/Broadwell/Skylake in getting work done, and that is what matters.

For mobile, the battery life is just the cherry on top.

Yeah, I think that's why I'm probably going to move to KabyLake from my 2600K rather than go with a 6700K or wait for SKL-X. If the 4.2/4.5 Ghz speeds are accurate (and I have no reason to doubt them), I probably won't really need to overclock. My PC is in a room which has pretty poor air circulation so the more I can cut down on heat generated, the better.

yeah, I wouldn't go 6700k now when 7700k is just around the corner and will clock better. I loathe to recommend that people "wait for [product x]," but if you can wait ~2 months, it'll be worth it.

I hope this statement will be true even when Zen will be released (e.g. Zen @ 4ghz @ 95W TDP is faster than Kaby Lake @ 3,6 GHz @ 95W TDP). But I'm sure people will complain about AMD uArch inefficiency. XD

This is not the Zen thread, though...

Will Intel final move the U and Y series to DDR4 when Cannonlake rolls around? Would think that laptop manufactures would be pressuring Intel to do so since LPDDR4 and now LPDDR4x should net decent power savings. What stopped Intel from enabling DDR4 on these processors since Skylake?

U already supports DDR4 for a long time.

Yeah, Cannonlake is LPDDR4. LPDDR3 was kept around longer than expected due to the insertion of Kaby Lake in between Sky and Cannon.

BTW, I reviewed the geekbench scores again and have come to the conclusion that the top 7700K is running at either 4.9 or 5. Unless it's fake of course. Still not the top score, although that is more because there are several 6700K results with extreme DDR4 speeds.

If Kaby Lake pushes Skylake down in price enough, then won't slightly overclocking cheaper Skylakes lead to nearly identical performance? The XPS 13 comparisons from earlier seem to show the only major thing being lower level 4k support. I'm more excited about a cheaper 6700k at this point more than anything else.
