There's only thing I don't like about Coffee Lake CPUs: Intel is mum about the 300 series chipset compatibility with Cannonlake and Ice Lake CPUs. I've never actually upgraded CPUs but it's important for many other users.

I've thought of that too.

I wonder why many aren't as enthused about x299? It seems to have a clearer future roadmap at least. But I'm probably missing something obvious...

it just smells of "quickly get something out to compete!!!!" coming from Intel.
What ??

These processors where announced before Ryzen and these processors are more power efficient then last generations 6 core line.

This is literally the complete opposite of "quickly get something out to compete". It's well engineered and has been on the roadmap for quite some time........

Tom's ran it at 4.9GHz on a 420mm rad AIO and it reached 90° during gaming.
Looks to me TPU got a heavily binned chip and you are more likely to get a similar chip from a store as Tom's did. If you can find in stores as this looks like a huge paper launch if other tech sites are to believe.

Yeah but where are those temp tests, almost nobody did that

reading the review and comments ...

i feel this new line-up was a forced answer to zen and intel basically corrected previous gen faults, improved manufacturing process & add more cores.

price-wise are well situated but is questionable if owner of previous gen need it or worth the change of mb also as the gains in gaming are minimal, productivity wise could be beneficial... but not for majority

for sure due e-peen both camps fans will buy the latest product and i encourage them to do !!! ....so we could buy slightly used cheap stuff...:laugh:

with this release they forcing amd to correct their mistakes and improve 1st zen's faster than anticipated... i love competition ty intel&amd!

This 8700K is actually best of both worlds. It has plenty of threads and also clocks ridiculously high for single threaded stuff pretty much out of the box. It does great with multithreading and also runs games well where multi threads don't count all that much (yet). They could bump up the multi clocks to at least 4GHz, but I guess it's a good balance. Intel is doing similar to NVIDIA with graphics. The chips boost so high out of the box it almost defeats the purpose of overclocking and most people won't even see the need to do that.

I noticed this too, a striking similarity in behavior when it comes to core voltage/temp and the OC ceiling it hits with Pascal/GPU Boost 3.0.

Its really a sign of a very strong process/node, and it seems the lottery effect is heavily mitigated by now.

You should check the Digital Foundry review. It rofflestomps the 7700K in games that can use more cores. Extremely smooth frametimes, better than any other cpu on the market.

Somebody gets the real world scenario :) Even a quad core optimized game will see a huge benefit because you are always multitasking anyway these days. Browser up for whatever? It will run on the spare cores. Streaming? Got two cores for that. Want to do in-depth monitoring at full GPU utilization, so very high polling rates? No problem.

And yes, the real profit is not always measurable in hard FPS, because most of the time, even with Ivy I can hold 120 fps in many cases, but you do lose that stutter that is so extremely pronounced especially at high FPS/refresh rates.

This 8700k is a winner, and I'm gettin' one :p

1080p and 1440p tests seem to be more GPU than CPU limited. Perhaps test with 1080Ti instead of 1080 in the future @ W1zzard?
Also no temp graphs. In Hardware Unboxed video he's sample went to 5,2Ghz but at 97c at load. Ouch.

Better question is what use is the high OC potential if you can't use it without buying AIO or custom loop and voiding warranty in the process?
Sure you can OC to a point but after that it gets too hot and throttles back down so net gain=0

This is why there are 720p tests. If you want to see raw relative performance that's where you gotta go.

At 1080p every GPU will provide different FPS, which is precisely the real world scenario where everyone runs something different. I would say its more relevant to NOT use the highest end card, there are way fewer people who have similar; oh and even a 1080ti will find its max with this CPU at 1080p, don't you worry. There are multiple games heavy enough for that.

@W1zzard awesome as always, and thank you for sticking to the 720p benches. I'm a big fan ;)

This. I generally don't care if they make the Z370 a one and done platform, as people generally buy a new mobo by the time they wanna change the CPU(never upgraded the CPU on the same mobo as well). But I'm kind of expecting Intel to jump even a bigger leap forward with Cannonlake/Icelake, so much that if it becomes one of the biggest jumps in years, It might just BE worth it to upgrade even from a 8700k(which I am getting), so I'm starting to care lol. I originally planned to wait until cannon/icelake but they're taking too long and I'm getting older now.

There are additional power pins on the CPU/socket that weren't used as such on Z270 / Kaby Lake. So KL has a few 'dead pins' that CL does use.

Which in all fairness is 100% logical given increased core counts in the lineup. And about your upgrade plans, yes man, I think for us early Core buyers (your Sandy my Ivy) this is the moment where it'll pay off. We actually run pretty darn similar performing rigs, yours at 4.5 and mine at 4.4 but a gen newer :D

EDIT: OMG 2500 thanks and 3k msgs, new milestones haha... wonder if I'll ever get that 1:1 ratio going :D

With some of these responses, you'd think Intel can design, fab, test, and distribute chips within months... WTH?????????

Yeah man they already have a Quantum Core chip laying around somewhere, hell they're even playing Crysis on it in deep space somewhere, probably with aliens.

You didn't hear? Next month Intel is releasing "instant coffeelake" chips. More cores! 15% Higher IPC!! similar gaming performance as kabbylake and you need a new mobo...

I think Instant Coffee rather applies to this gen seeing how they pulled it in. :D Nice one

It's the same reason why hex core CFL wasn't confirmed up until Q2 of this calendar year. The reason being they wouldn't want to cannibalize the sales of existing KBL chips, now imagine if the rumor of 8 core CFL were true, what if it'd also work on Z370 o_O

Maybe Dave can fill in some of the details here ;)

Wait didn't many users say that the hex core was in the pipeline a long way back, or am I imagining things?

Almost... ALMOST feel sorry for all the nubs who jumped on and delidded that 7700k.

You're wise :) If you do suffer from buyer's remorse, now's the time to sell it off. It will not hold its value well either way.

There isn't an almost. I don't feel sorry for them because, frankly, there isn;t a reason to feel sorry for them. ;)

The only place where that hex will show off over the 7700K is perhaps towards the end of its life in a few years.

Depending on the number of threads the frequency differs. Highest boost is 4.7

Let me word it better. What was the sustained boost under cinebench MT?

The reason that I'm asking is that some reviewers ran their benches with multi core enhancment enabled, which meant all 6 cores were locked to 4.7 GHz, all the time, even under cinebench MT.

Well too little too late imo, I would recommend going for Ryzen over this.
That's actually make things even scarier, if this is only interim answer.

"Guys ryzen is out what we should do?"
"Nah just add +2 cores and call it a day"

Imagine the real answer (Ice Lake) will be, if they are not mess things up ofc

Icelake is well over a year away, at least if 8 core CFL rumors are to be believed. There's also the transition to 10nm which isn't going smoothly, Icelake is 10nm+ btw.

Then there's 0 ipc gains from SKL to CFL, only more cores &/or higher clocks, Icelake wouldn't bring the magical 10% (or above) ST performance increase that many Intel users expect each new gen.

I think I'll just grin and bear it. Either move to Ryzen or x299 next year. Not sure.

If I remember correctly my board's BIOS defaults have that enabled. I do remember turning it off at some point and keeping it off.
