Intel's Core i7-7740K Kaby Lake-X Benchmarks Surface
Two days, two leaks on an upcoming Intel platform (the accelerated release dates gods are working hard with the blue giant, it would seem.) Now, it's Intel's own i7-7740K, a Kaby Lake-X HEDT processor that packs 4 cores and 8 threads, which is interesting when one considers that AMD's latest mainstream processors, Ryzen, already pack double the cores and threads in a non-HEDT platform. Interesting things about the Kaby Lake-X processors is that they are rumored to carry 16x PCIe 3.0 lane from the CPU (which can be configured as a singularly populated 16x or as a triple-populated 1x @ 8x and 2x @ 4x PCIe ports. Since these parts are reported as being based of on consumer, LGA-1151 Kaby Lake processors, it would seem these eschew Intel's integrated graphics, thus saving die space. And these do seem to deliver a quad-channel memory controller as well, though we've seen with Ryzen R7 reviews how much of a difference that makes for some of the use cases.

Leaks came from the SiSoft Sandra Benchmark, again, which shows the Intel Core i7-7740K running at 4.2GHz base and 4.5GHz Turbo clocks. The X-series family of processors is expected to have a wide range of various core-configurations from 4, 6, 8, 10 and 12-core processors, on the new X299 platform. At the same time, Intel will also have a Skylake-X CPU, expected to be for the top-end 12-core/24-thread line with 44 lanes of PCIe Gen 3.

I agree that the article is not really that professional as many other press releases, I still prefer Ravenlords and W1zzards articles over many other sites who just copy&paste press releases.
I do know then that at least someone with knowledge has read an info, thought about it and edited it (even with his own opinion written into it). The infos he has in the article are just infos. I am able to read his personal opinion out of the post. So no biggy for me. Most of us readers should or are mature enough to be able to distinguish between news and personal opinion, even if it is in one article.
@4core is enough. Well.. it is. But not for Intel and not for the price they will surely ask for the 4c/8t 7700k.
And for all of computer programming, there is always a rule: whatever hardware you have, there will always be software to get it down to it's knees. So we should thank AMD that they went all in the consumer market with 6 and 8 cores and maybe more, so Intel had to react. Offering a measly (IMHO) 4 core is kinda lame.
If it's like their previous HEDT parts, there is no iGPU to eschew. If that's the case, then they actually aren't saving any die space and the quad core parts will just be cut down versions of a higher core count die which is fairly typical of HEDT parts. So it's yield optimization and likely higher frequencies with lower core counts.
Do you want Intel to not offer 4-core parts and have a 6-core minimum for HEDT? I'll grant that the 3820k and 4820k didn't make a lot of sense for most, but it's still good to have those quad core options even if they were hexacore and octacore rejects (HEDT being, in turn, Xeon rejects).
I have to agree with several posters that your editorializing isn't adding anything, particularly if your snark is coming from ignorance.
"Average performance :|"
@Ravenwolf If only AMD would have released a highly binned single CCX 4 core version of ryzen maybe it could have bumped the 7700k off of the gaming throne. Instead you are stuck with 8 mediocre cores with only 100MHz of overclocking headroom :(
Now we have Core i5 on HEDT platform, is INTEL trying to phase out mainstream platforms for good? Does i5 even belong in HEDT family.
Because the larger 6,8,10 core are all Skylake based.
It will have dual channel ram based on what has been leaked:
It will be just like a 7700k but with the iGPU disabled and on the new HEDT socket.The HEDT platform supports higher wattage processors compared to LGA1151. The VRM is much stronger and there are more power pins on the actual socket. In theory this should allow you to get a stable voltage at higher amp draws. To put this into perspective: a 7700k will draw about 150watts at 5GHz compared to a 6950x at 4.3GHz draws around 230watts.
The article has some mistakes I'd like to point out:
a) a 4 core / 8 thread CPU with 16 lanes is hardly "HEDT", it's the 7700K ported to the X platform and renamed, nothing more or less.
b) it has no quad channel, I already saw official Intel papers on it, pointing out Dual Channel for 7740K.
Sorry @ the Intel fanboys who care to defend this garbage. But it's garbage. ;) The 3820 (which I owned before) and 4820K btw. had Quad Channel and 40 lanes - so are not comparable to this (soon to be) overprized crap.
Still plenty boards on z270 can handle such wattage....
... the other side if this is you wont hit that wattage in a quad unless you use ln2. A better power plane isnt really going to help much as it doesnt need much in the first place. On any (intel) platform, the difference between a $140 board and best vrmzomg board ever, makes little difference...what 50-100mhz and .05v on ambient cooling at best???? I guess im saying i wouldnt hold my breath because of better power sections on a mobo platform for a measily quad core. :)
And if the X299 platform behaves anything like the X99 i pity the person getting it, as X99 is the most fragile platform i have ever encountered.See the E5-1603V4
I wonder what things would be like now if people had spent the last 5/6 years trying to make the best use of all those cores? Instead of focussing just on Intels 'roadmap'...Sweet! Nobody needs a MoBo over $140! I puke when I see what some people pay for a MoBo, especially on Intel side.
Not my best work, and not only do I understand where most of you are coming from, I agree with most of what has been said. Slight side-line in this article - the delivery wasn't as sound as it could have been. And those parentheticals and run-in-sentences could have been avoided.
Anyway, problem acknowledged, and rest assured this will inform future articles. Piece by piece we'll reach an agreement between editor and TPUers =)There has been an answer to your question already regarding this issue. While I am ignorant in many aspects of this world (as in, not knowing everything), if latest information bears fruit, these will be repackaged consumer processors, which do carry the IGP. Hence the referral. So as you see, the snark has basis. Even if it could've been delivered in other ways. Thanks for commenting.
