Um, the IPC is identical but Kaby Lake consigns Sky Lake to the history books?

We'll agree to disagree on that one, Mr Leather. ;)

It's actually nearer to £350.

Hence approx!

£60 is quite a big `approx.` !

While it doesn't render an already purchased Sky Lake cpu worthless there is also exactly zero reason to opt for a Sky Lake once Kaby Lake hits store shelves in quantities for those who are on older systems.

Still no reason to upgrade from my 3770K.

Well from that review, the Sky lake uses less power and is almost as fast with a lower overclock, so unless you want peak overclock performance all the time I can't see the point of this cpu.

It's a shame it wasn't tested at 4.8GHz to give a better comparison.

Good review, nice to see Kaby Lake released (from the NDA at least).

Doesn't look like an overly worthwhile upgrade from Sky Lake which I know was expected, but it might give Zen an open goal of sorts if its launch matches some of the hype.

Well, that might be true over there, here where i live (argentina) an i7 6700k is aprox 395u$s+VAT 21% (best price i can get), so when kaby lake gets here i assume ill get an 6700k for ~325u$s, and of course a 7700k will get here at aprox 425u$s

UK is seeing nearly 1-1 price conversion on computer hardware at the moment.

Unsurprising with a $1.20:£1 average exchange rate plus 20% VAT.
Admittedly it was REALLY annoying to still see £=$ when the exchange rate was $1.40:£1 and higher.

Personally I feel the i3K is going to be the gem that sparkles brightest - it's been suggested it can best the 4670K and 2600K when OC'd.

Still only time will tell...

So are we at the point now where a Kaby Lake CPU (and presumably a subsequent mainboared & ram upgrade) would be beneficial to those of us on an older i2500k intel setup? Or is it still a case of questionable cost vs. benefit and the kind of thing only worth doing if you suffer hardware failure?

Every time in the past few years I have posed this question to friends, they have mostly suggested a GPU upgrade offers a better performance boost for the money.

Have the 7700 and 7600 (K and non-K) parts dropped VT-d?

The Intel ARK pages don't show it listed at all.

Do these work in existing boards or do you have to have the new board for it to work? also, do skylake cpus work in these boards?

Barely an improvement. Still don't see a reason to upgrade from my XP1700+

It's the same socket so they should be compatible, but will probably be BIOS-dependent (similar to Haswell & Haswell Refresh with Z87 and Z97 motherboards). So Skylake CPUs should work in all Kaby Lake boards (e.g. Z270) but Skylake boards (e.g. Z170) will probably need a BIOS update to recognise Kaby Lake CPUs.

Is it worth upgrading for performance gains if you have a 2500k or newer Intel quad core? No.

Is it worth upgrading for the better feature set? Depends if you want the new toys you won't have on something old like a 2500k system like for example M.2 Nvme support, USB 3.1 Type-C Gen2, being allowed to use 4K Netflix and so on, if you are not going to use them, then no.

But if you are going to upgrade anyway due to old hardware failing / for the sake of it then may as well opt for the newest tech.

Just my opinion of course.

Can you please retest these cpus at 4.8Ghz and do all future tests at 4.8Ghz to give a fair comparison against the older cpu shown tested at 4.8Ghz.
Giving it a slightly higher overclock and saying it's a bit faster is pointless.

Actual lol

Not worth upgrading from 2500K? I would say so. Not from Haswell or newer, certainly, but 2xxx series is PCI-E 2.0 still. Only Ivy had Gen 3. And it's MBs only had 2x SATA 6G. Upgrade from Ivy would be 'consideration' at this point. But both I'd wait to see what AMD offers.

Does anyone really only consider upgrading on CPU alone? I can't say so. You're missing out on M.2 support at a minimum, let alone all the new BIOS features, much better fan controls, add-in software like free Clone/RAMdrive that's actually quite useful (on ROG/Strix) and two DIMMs of DDR4 gives you 16GB - more than enough. (Yea DDR4 is expensive now though :/)

Vault-Tec - yes to both ways afaik. But you'll unlikely get the best OCs from KB/Z170 combo.

For gaming notebooks - KB+GTX 10 series is a killer combo. Fast peak clock speeds on H series / plenty of U series has eDRAM/Iris and even 1050 Ti's are solid FHD capable GPUs. Throw this and an M.2 into a 15.6" and you've got a great thin and light.

Are you actually going to use those new toys though?
Because if not might as well wait for even newer toys.
Harlequin 4th January 2017, 15:50 Quote
get a pcie4x card for M2 on an older board?
TheMadDutchDude 4th January 2017, 16:12 Quote
You can do that, but unless you have a Z77 or newer board (might even work on Z68) then you are going to struggle to boot from it without modifying your BIOS/UEFI.

The whole point of it, for me, is for it to be a rapid boot device and store a few games that really benefit from fast loading times (big maps for example) - that's what mine does.
