Not even 5% performance increase?? Is this legit?

Close to no difference...

Holy guacamole, dat performance increase! Looks like I won't upgrade my CPU anytime soon.

There is one - the price of the new units will be 100-150 EUR higher than the predecessors :banana:

So Intel now releases CPUs with no difference at all to the previous gen. What's next? A cpu which has lower performance from the previous gen?

Actually if you look again at the numbers, they show the 7700K is slower than the previous 6700K clock for clock! They score almost identically in every test but the 7700k is clocked higher.

The 6-core Coffee Lake will probably be similar in performance to Kaby Lake in terms of IPC, possibly even lower as I suspect it may not overclock as well as the 4-core version due to heat. If it does, it means they have to cherry pick the cores, which will mean it will be unattractively more expensive than the 4-core.

I was thinking about this earlier. I bet they use TIM and not solder which will make the 6-core unviable for overclockers without a de-lid.

Has it been tested with 7?

How come every time Intel releases something I got the feeling that just going for Haswell-E hexacore was pricey but still the right decision? Not that much of an emotionally moving release imho.

Anyone really wondering how much will 7700k overclock when its already boosting to 4.5ghz? This article said it can reach 5Ghz on 1.49v (burning!). How owesome is that? http://www.pcgameshardware.de/Core-i7-7700K-CPU-264844/News/Benchmarks-mit-4-5-und-5-GHz-aufgetaucht-1214658/

If you translate the coresponding paragraph from the PCgameshardware article, it reads like this (google translation for the sake of objectiveness):

Speaking of overclocking, the Core i7-7700K do not appear to be particularly bitchy. Publish results suggest that relatively little voltage is relatively far behind. About 4.9 GHz with 1.29 volts. However, this is always accompanied by high temperatures around 100 degrees Celsius. If you want to overclock in the long term, you should definitely invest in good cooling. Kaby Lake also has a series of streams. The so far shows so that with good models 5 GHz with little voltage can be achieved. The Chinese of the latest benchmark leaks had to invest 1.49 volts. The extent to which the value is optimized remains unclear.

This are temperatures I haven't seen mentioned in the past 10 years... not sure even proper watercooling could cope with 100°C that easy. A bit scary tbh 😀

The only improvement i can see is the Igp...who uses Igp, quess my 4790k will stay for a while longer, maybe 6700k prices will drop enough for a worthy system upgrade.

As I see it. Only reason to buy this is if you are building a system from scratch. As for a upgrade, I will wait and compare if Zen can deliver a better product in the same price bracket. I use a lot multi core applications, so more cores would be awesome. Though I don't believe Intel will deliver in that department in the near future.

From Wiki:

Kaby Lake features the same CPU core and performance per MHz as Skylake. Features specific to Kaby Lake include: Increased clock speeds across all CPUs models (increased by up to 300 MHz) Faster clock speed changes Improved 14 nm manufacturing process Improved graphics core 200 series chipset (Union Point) on socket 1151 Up to 16 PCI Express 3.0 lanes from the CPU, 24 PCI Express 3.0 lanes from PCH Support for Intel Optane Technology

source: https://en.wikipedia.org/wiki/Kaby_Lake So yeah, nothing fancy. Just optimizations and some iGPU boost.

it will have support for Netflix 4K and more pwerfull iGPU. Definitely worth extra 100 eur 🙂

And what about the dimensions of the physical package without the HS? If the actual CPU is smaller it will be even harder to cool and 1.3v might equal 1.35v on Skylake. At those voltages you need to have decent cooling otherwise they're toast. You need to move the heat away as quickly as possible and without much surface that isn't going to happen!

I would like to see IPC benches, head to head @ 4Ghz, so we can see every tick and tock that Intel has to offer since last 3 generations. every time they just bump the frequency a little to look faster then the old model, they should be sued for forcing so much pc garbach they they force you to by new mobo twice a year!. since SATA 6Gbs/USB 3 I dont see good reason to release new socket every time. As soon ZEN is out - *** intel ;-)
