Intels Skylake-X and Coffee Lake CPUs Discussion

[Lanfear1]

pretty good, considering:

- those are EU prices with VAT
- launch prices which are higher then later prices

Thanks!

The 8700k is a bit higher priced compared to the 8600k then I would have thought.
The 8700k offers .1 base clock, .2 turbo, 3mb more cache and Hyperthreading for ~ 42% more cash

We also thought, we'd get a 7700K for 360€ at start, but we didn't. But yes, now you can get it for 320€, so you might find a deal if they are ever in stock.

Price dropping any time soon I don't see happening though.. This is finally the time they are leaving 4 cores behind and people will just flock for the CPU, I'd expect them to be sold out for a really long time and that will push the prices up, much like it did with the 7700K here. Unless it flops that is, which I don't see happening, because Zen 2 is still ages from now and Intel has pretty loyal fans.

But overall, if the platform price doesn't hike up again, it seems like a sweet deal indeed for many.

[Sorshen]

390 euros, what the fuck... a 6850K is 340 euros.

8600K is the best value I guess.

Im very interested to see in which games equally clocked 8700K would pull ahead of 7700K due to them scaling beyond 4 cores/8 threads currently

Talking pure stock speeds, it will have a lead cross the board, due to improved ST performance(according to Intel).

On OC though, if it can hold clock speed near 5GHz it will still win, but if not.. I have a suspect feeling the 7700K will still be the 1080p king. And ofc outside of 1080p, as always, CPU doesn't matter past a certain point.

doesnt look impressive at all.

How? It's around exactly where it was predicted to be months and months ago. Now sure, if ones expectations weren't realistic, then yes.. It's not impressive. But you are getting more multithreading from a 7700K, which is really nice, as it's the only thing the 7700K is missing. Although that MT score does puzzle me a bit, because it should be nearer to 1400-1500 on cinebench. Though it's possibly throttling in the demo setup, who knows.

[Life-Binder]

Ive reasonably sure that CB multi-score is just on 3.7 stock clocks, not the 4.3 all-core boost (either that or throttling yeah)

but we'll see for sure when NDA lifts

It's likely that the 1.230 score is due to running @ base clock speeds of 3,7GHz instead of the advertised 4,3GHz Turbo.

Which means HP's motherboard firmware is likely unfinished because in that example it had watercooling.
Either that or the CPU is being severely hamstrung by temperature constraints, knowing and having experience with HP my guess is the former with the mobo firmware not being done.

This however does actually show that Coffee Lake = Kaby Lake = Skylake.
As the performance scaling from a Kaby Lake fits perfectly into the 1230 score.

For those of you interested how.. Napkin Math inc:
991 (average score of an i7-7700K in CB, multithreaded) / 4,5GHz (all-core Turbo) = 220,22
220,22 * 3,7 (Base Clock of the 8700K) = 814,82
814,82 * 1,5 (50% more cores/threads over the 7700K) = 1.222,23 CineBench Score extrapolated

Within margin of error and variance per chip per test, meaning that the IPC of the Coffee Lake SKUs are identical to that of Skylake and Kaby Lake as well as the underlying uArch which also brings me to my earlier mentioned point of the TDP being shenanigans executed by Intel.

That's also best case scenario, if that benchmark score was indeed at it's 4,3GHz frequency all-core then things don't look that optimistic.

From what I've seen and read so far... I'm going to go out on a limb and say that it was the base frequency of 3,7GHz at play here.

btw there was some rumor that Coffee CPUs will work on Z270 and maybe even Z170 if the mobo manufactutrers release the necessary BIOS update .. but only the CPUs will work, not the iGPUs


unconfirmed

Unlikely to be official, possibly a "hacked" BIOS... there's been an 8700K leak and the contact pins and even SMDs are identical to Kaby Lake.
So technically it's possible... provided you have a BIOS that will support it, which will not be official as Intel doesn't want that... they've clearly shown that already.

They would have to have found a "leaked" prototyping firmware from previous Z270 boards though which isn't encrypted for them to adapt to the new boards.

It's possible ... but difficult and unlikely.
That said they did the same to enable RAID0 TRIM across all chipsets after the key was found and it works even on P35 chipsets... so it's deffo possible.

[Sorshen]

There was a 'leak' a while ago saying that only the i3s would work, tho who knows. 8350K kinda is to 7600K what R9 280X was to 7970GHZ.
Knowing intel's greed, they'd probably intentionally withhold the microcode/bios updates to grab some cash with Z370. I still remember them screwing over G3258's "lock" and Skylake BCLK overclocking.

I can tell you right now. Definitely Watch Dogs 2 and MAYBE Battlefield 1 & Battlefield 4. The end.

[Life-Binder]

you forgot crysis 3 and maybe GTA5 too

and Im sure there are a few more too/will be in 2017

- - - Updated - - -

Dishonored 2 too apparently




- - - Updated - - -



perfect comparison, R5 1600 6c/12t @ 4.0 vs R5 1400 4c/8t @ 4.0


1600 pulled ahead in BF1, Mafia 3, Ashes, DEMD (~15 fps), TW:WH (nearly 50% difference in min fps) .. Hitman was a marginal increase

from the video - "on average, 1600 had 27% higher min fps than 1400"

27% is more than I thought


8700K will do good

Most of the difference is due to R5 1400's inability to fully utilize the GTX 1080Ti. In the real world scenario you wont have an R5 1400 paired with a GTX 1080Ti and a 1080p monitor.

I'm more interested in Ryzen more at the moment, thanks for the comparison, I'm confident going with Ryzen 3 1300x now.

[Thunderball]

With those i3 pricings Ryzen 3 and 4 core Ryzen 5s are dead now.

[Deleted]

You mean the opposite? Going by those you can get a Ryzen 5 1600 for the price of an i3.

The other problem will be 20-30% extra heat and energy usage for Intel.

I kinda hope at least wow can utilize the 2 additional cores since its such a CPU pig as it is.


I cant wait to get my hands on my 8700k vendor sample so I can build my rig to replace the 7700k rig I use now for gaming.
