Does Kaby Lake offer anything that makes a lower OC not a big problem? I have a 4970K @4.5. If I get a Kaby Lake CPU and can't get it faster than @4.2 or so, won't it still be faster due to er... new tech?
I am thinking about a new system in Q1 of this year, hence my question.
(Come to think of it, maybe this new CPU will reach 4.2 already in turbo mode...?)
Reports suggest IPC is about the same for Kaby Lake and the older Skylake platform. In which case, your CPU is about 5% down compared to Skylake in single core performance. About 7% down in multi-core performance.
So expect Kaby Lake to only be a few percent better in terms of IPC. There are other advantages though, like Optane support, on-board USB 3.1 etc. Plus the advantages Skylake brought to the table, like U.2, M.2, NFC etc.
If the boost speed is 4.5 there is no real need to OC, is there...? When does that boost/turbo kick in? Whenever it is needed or only under certain circumstances? Why OC a CPU that has a boost like that?
Kicks in when required.
Many would agree with you regarding the need to OC. 4.5 to lets say 4.8 is only about 7%, so expect the same in terms of frame rate. It's a free performance gain though, so if your system can handle it, why not go for it. Overclocking is relatively safe these days.
The other point is of course that many overclock not because they need to, but for the sense of achievement, for the fun of it.
Then of course there are the less well informed who are fooled into thinking a few hundred megahertz will be utterly awesome in terms of performance... which of course it wont be.
There were plenty of reports of Skylake CPUs running at 5GHz or better before the production chips hit the market. Until reviews of commercially available Kaby Lake CPUs and motherboards are published, there's little point in speculating about comparative performance.
Yes, very true. I remember all of the claims re Skylake too. NDA is lifted Jan 5th I believe, so shortly after that we'll have a "somewhat" better idea.
Even then it won't be the full picture though, 6 or 7 reviews doesn't tell us how the majority of the chips preform. The real picture will emerge in 6 months time when not only are all the reviews done and dusted, but a multitude of owners recount their experiences with the new platform.
The Z270 chip-set is another variable to consider of course.
He is a friend, now what he do , the NDA, probaly wy he is a little cryptic.
I'm surprised he said as much as he did, given the NDA isn't lifted for a few more days yet.
I'll be eagerly awaiting your comments too Hasse, re the 7700K, once the NDA is lifted.
