If that's true, then I am hopeful for Skylake-E clocking well also. Around 5ghz with a hex core Skylake? That would be so legit.

:thumbsup:

Based on how far behind i7 4790K @ 4.7ghz is vs. 5930K @ 4.7ghz with dual 980Tis @ 1300mhz, I doubt even a 5Ghz Skylake-K quad will keep up. Given how long Intel CPUs last nowadays, for anyone contemplating flagship $500+ cards in pairs (and if that's their upgrade path for 2-3 generations forward), it's going to be well worth it to wait for the Skylake-E 5820K successor.

This is especially true this time since the new 10nm micro-architecture from Intel is now only slated for 2018 which means for the next 2.5 years or so, there will hardly be any tangible increases in IPC. With DX12 and Windows 10 though, we should see more games taking advantage of more cores which will allow X99 and its successor to shine!

Not that it matters. Stock Haswell @ ~3.5GHz or so is enough for any single player single GPU AAA title @ 1200p or above. Anything you gain by slapping another 400MHz-1GHz on top is a few minimum frames.

Assuming those scores are real, that's rather disappointing. It's hardly faster than a 4790k at similar speeds.
Well it is Spi so dunno what you have expected :hmm:

I think Skylake could be 5-10% faster than Haswell on average which is an "OK" improvement given the fact how efficient Haswell already is. The bad news for Skylake is that the models that are flagship won't have edram and Broadwell will probably be faster in select few workloads (like gaming with high end dGP) which will seem odd to many users.

PS I do feel good about my recent 4690K+z97 purchase, should last me a long time.

Turned to the dark side ??

Yea Core i5 Haswell will be more than enough for 2-3 years, but im waiting to see how DX-12 games will handle multicore CPUs. But i dont expect first gen DX-12 games to obsolete Quads.

haswell→broadwell= 4% (Clock-for-clock Performance)

haswell(4G-4.4G)→skylake(4G-4.2G)= D:

Looks like 5.2 Ghz to me.

details, details . . .

Cherry picked or not, 5.2GHz @ 1.35V is indeed better than Broadwell-K's 4.8GHz @ 1.42V. Should be a fun chip to play with and a worthy Haswell successor.

I'm interesting in seeing what it does under phase. Broadwell-C was a total dud in that department.

I do think Core i5 5675C is a great option for those keeping their LGA1150 boards and DDR3 kits though, what Intel needs to do is improve retail availability.

Agreed. It may also be a great option for DX12 gaming if devs start using the iGPU for compute functions.

Another reason why people should take these tests with a huge grain of salt.

Intel Core i7-6700K 5GHz Super Pi 32M Passed @ 1.31v Air Cooling

Matches what HKEPC editor said in forums.
It also boots with a mere 1.285V:

When will it be possible to buy them. Will the Skylake launch be like the Broadwell launch or will they actually on or around August 5? Reviews on Broadwell have been trickling out for over a month and a half now and not a single CPU to be had at retail in most of the world.

Availability could be rough next month, should get better September onwards.

Quick question guys in terms of the desktop cpu can you tell me the pcie lanes for -
Haswell
Broadwell
and the plans for skylake
On z series boards, i want to say 16, 20, & 20 again for skylake.
For me i'm also looking to increase storage speed on 8+ drives so i'm looking to see what is my best option when upgrading to z170 is, what i should look for? in terms of maintaining high bandwidth and the problem with additional media controllers being limited by lanes.

All the CPUs got x16 PCIe 3.0+ DMI from the CPU.

Skylake just got a twice as fast DMI interface with x4 PCIe 3.0 instead of 2.0.

Else it looks like this. Remember all chipset features sits on the DMI that is a x4:

HKEPC clarified that and more about the overclock here:

HKEPC acquired Intel Core i7-6700K processor engineering samples of VID voltage is 1.205v, test ambient room temperature of about 24 ° C, GELID The Black Edition Air Cooling and GEILD GC-Extreme Thermal Compound, use SlowMode into the operating system and start CPUZ After entering the home idle state, and ultimately successful only when the voltage at 1.35v recorded a 5.2GHz core clock, and can be maintained for about 4-5 seconds, the pulse test CPU overclocking limit in air-cooled, not with 24 X 7 is considered.

To avoid that Zhang CPUZ testing and certification picture caused unnecessary misunderstanding, HKEPC 21 announced more Intel Core i7-6700K preliminary air-cooled overclocking test data, in the same test environment, the particles Intel Core i7-6700K processor engineering samples In 1.285v CPU voltage, following the success of 5GHz CPU clock starts when Windows XP operating system, and 1.312v CPU voltage via 5GHz Super Pi 32M air-cooled test.

Their explanations are boggus and contradicted by their own voltages that imply perfect frequency/voltage scaling from 4 to 5.2GHz, this has never been seen in any process to this day and certainly not with what we already have at hand from nearby SKUs, undoubtly they used LN and are now caught backpedaling within muddy waters, quite a clarifiation, indeed...

Fully agree. I think 6+ cores is the way to go from here on out for the gamer looking for max MGPU performance.

Not that it matters. Stock Haswell @ ~3.5GHz or so is enough for any single player single GPU AAA title @ 1200p or above. Anything you gain by slapping another 400MHz-1GHz on top is a few minimum frames.

That situation you described isn't hardcore enough to justify a hardcore platform. More hardcore please.

Thanks for posting csbin, nice find! 50W less total system power despite slightly higher nominal TDP? Interesting.

Other than the fact that if true those voltages will put the nail in the coffin of your reputation what kind of evidence do you have to prove them wrong? Please don't come up with Broadwell-U NotebookCheck voltage curves, I'm not in the mood for laughing.
