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.

-- Images removed at request of a motherboard vendor --

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.Source: ETeknix

Man, articles like this makes me really disappointed in the direction Techpowerup is heading.

I don't disagree with the article but if I want to read the editors opinion i'll read the editorials. This feels really unprofessional.

Good morning to you as well. TPU is friendly and focussed on real people who are interested in our PC tech. RL writes quizzical stuff now and again because, let's face it, what on earth is this product aimed at? 16 lanes? Errr. Let's hope the chipset has 50 extra plus some fabulous new bridge.

That does not make this any less professional. I'm reading news to form my own opinion about it, not for the editor to do that for me. Sure, a jab here and there on occasion, I can look past that. I'm not without humor.

But this article is a great example of where this goes overboard. TPU used to be really good (and still is), but this is a low point.

The article is already slightly edited, it was even worse before

The article is hardly political or opinionated. It's somewhat quizzical but my post was more incredulous. When the tests come in then things become focussed. It's just a vague news rumour at the moment.
I lived in Stockholm for 10 years. Jonkoping also. And worked in Lulea (guess the company).

I like the new direction.

Reporting anything about the last generation of intel processors must be hard.
As not a lot has changed in the last generation or so.
But now AMD is back in the game what is wrong with ragging on intel.
4 core on there enthusiast platform really?

Hell PC's where more fun with the CPU wars RISC vs CISC and AMD vs INTEL.

Now days everything is bland why not spice things up a bit.

That's not the point. TPU should not be forcing opinion on their readers. The quality gets so much worse and the comment-section will get really toxic. (Their credibility will also falter)

The commenters/users are the one that should be ragging, not the editor. That's why there are opinionated editorials.

Again, i'm not saying that there should not be some personality behind the text.

if i wanted spice, id read charlies articles at semi-accurate.

Theyve had a similar style before where the author's opinion was injected into news articles... it didnt work out. That writer got a ton of flack for various appropriate reasons and bailed or was let go...

I dont appreciate being led in a particular direction either. Saying nvidia is scared of vega hence the moving up of volta or whatever was really offputting.

4 cores arent measily. Its a sweetspot for price and performance. Regardless if you are spoiled by core count, 90% of users cant use more than 8 threads anyway, so what does it really matter?

Tough read with the parentheticals litering that first para (one also isnt closed)...sorry for the public mention... i digress.

I smell Fudzillish style even.

Can we ask to mark these articles with yellow background.

4 cores is the sweet spot for price performance because intel has been price gouging all the higher core count parts. Right now you can get a 6 core Ryzen for less than an i5.

Which is pretty sweet. But as long as Intel does not want to have "internal competition" with their own Xeon line-up the prices won't change.

Agree Re: gouging. Agreed. We're getting some competition finally. Single thread 5Ghz Vs. 4Ghz multi. There's still some separation in use scenarios and I'm concerned that Intel will have something up the corporate sleeve.

Off topic: As you don't appear to have your own site, and I don't do utube comments, can I say I really enjoy your videos. Hair is not outrageous enough however.

Truth, but it is what it is... 4c8t is really all 90% of people need.. and will need for the next few years. So, yay for more cores cheaper that people cant generally use!

Quad channel for a 4 core setup.
Wouldn't that be something :)

I don't mind an opinion sprinkled in if limited. That said, this one is a mess. When parentheses are used inside of parentheses you have moved beyond reasonable commentary. Perhaps a close ) is just missing? Either way, way too much additional commentary (though I still like some sprinkled in) if the result is a mess (which is was, because even the author (who generally writes great articles) got confused).

From the article:
Interesting things about the Kaby Lake-X processors is that they are rumored to carry 16 lanes of PCIe 3.0 from the CPU (which can be configured as a singularly populated 16x or as a triple-populated 1x, 8x and 2x, 4x PCIe ports. These also eschew Intel's integrated graphics, thus saving die space (which could've been used for more cores instead of keeping the same 4-core, 8-thread configuration? Maybe?)

Maybe if devs pushed the core thing, we may have seen Intel move off their asses. AMD took long enough, but finally gave us that - more cores/good price. Hopefully the industry makes use of them.

An entire memory channel at xGB/s for each core. Directly connected and separated link. Good thinking :)

Has there ever been a 4c/8t HEDT chip from intel? Cause they seem to be going backwards. (Note that I don't mind fewer, more powerful cores, but this is HEDT)

For X79 you have the i7 3820 and the i7 4820K

I agree here. I'd prefer less posts or fewer words if writing a paragraph properly seems too much of a thinking effort for the editor. Techpowerup is a great site with really smart people around, so we should all try to keep a good level in speech. Don't let Trump ways... sorry, now I'm lowering the discussion level.

About the CPU's, yes, nothing to get excited about, but good info to remember anyway; Intel doesn't feel new AMD cpu's will have any impact on their business in the short term, hence they keep the launch strategy.

Well in my opinion I think its ridiculous to go back down to a 4 core 8 thread processor as the base on the HEDT platform. For awhile they have been starting at 6 cores which seems right to me based on who the platform is designed for (As 4 cores is enough for most users on the regular platform, this platform was more for the professional market or people doing content creation or similar). My main problem is that the specs mimic the regular platforms i7 but with quad channel support which I don't see a point to except in very limited situations. It just seems like a downgrade to me for the platform, however I am curious how it will be priced.

Eventhough I hate intels business practice I agree with him. They should maintain neutrality and let the user be the judge and let the forum / threads tear intel apart. If they start handfeeding us the oppinion "that obviously is the right one" s*** goes south and alot of people will start considering Techpowerup as biased site instead of a scientfic and neutral review site (which I still think techpowerup's core is), but a new trend to push opinions have been set by some of the writers. ( I would say that Techpowerup should discuss their vision and make sure it gets enforced (even if the result differs from what I hope for :) )

They actually gave them more cores a long time ago! :D But in a optimistic platform not able to compete with the way software was and still is coded. :)
