Intel Core i7-7740K and i5-7640K Codenamed "Kaby Lake-X," 112W TDP, No IGP

The two new quad-core processors Intel is fielding against AMD Ryzen, the Core i7-7740K and the Core i5-7640K, which we described in our older article, will be based on a refined (or at least relabeled) silicon, codenamed "Kaby Lake-X." The current i7-7700K and i5-7600K desktop chips are based on the same silicon as the rest of the 7th generation Core processor lineup, codenamed "Kaby Lake-S." It was also reported in the older article that the TDP of these chips will be rated at 100W. Turns out that they're rated even higher, at 112W, according to PC Games Hardware (PCGH). The top-dog AMD Ryzen R7-1800X features 95W TDP.

According to PCGH, what sets Kaby Lake-X apart from Kaby Lake-S appears to be Intel disabling the integrated graphics. You now need a graphics card to get going with these chips, and it will get trickier if you want to recover your graphics card from a bad BIOS flash. The chips also reportedly feature a high-performance thermal interface material (TIM) under the integrated heatspreaders (IHS). Compared to the i7-7700K and i5-7600K, these chips feature minor 100 MHz speed-bumps, but Intel could make them better overclockers.

Update: Apparently these two chips are built in the new socket 2660 package, and will be launched around Gamescom, some time in August.

theoneandonlymrkIf you have more money and invest in hedt motherboard why would you want a mainstream CPU in it??
That platform needs more pciex lanes and memory channels then the chips can at this moment provide so half hedt's performance advantage wouldn't be used, pointless imho.
Well, the two are not exclusive. Remember the i7-3820? 4c/8t, yet it also could provide the whole 40 PCIe lane and ran quad channel.

Clearly with such significant innovations from Intel, Ryzen doesn't stand a chance.

I mean 100MHz clock speed boost is so massive that it's almost unheard of, isn't it? Also, the fact that Intel claim to be "confident" of seeing off the competition, gives me complete confidence that they will prevail. Obviously.

Looks like a desparate move from Intel. This could be a signal that Ryzen is probably more than a match for Skylake.

Onto the CPU itself, 112W TDP wo/ IGP. Why not just get yourself a X99 HEDT or wait for Skylake-E (and possibly X290 chipset)?

IceScreamerHmm, this looks to be a sign that AMD really has something decent in their hands. But seriously, what's up with that TDP, I know clocks rise the TDP but 21W for a 100Mhz clock seems high.
Not really they just reacting without it costing any thing to them, if some ones started to leak shit at AMD i hope they get fired and it seems like no one is.
If Intel had some thing concrete on RyZEN they would of done more than this ( if needed ) but i guess it's easy to lower the price if needed so it can be a last resort.

To me this news now is all for AMD as they could say hey we can do that too.

Well, that's kind of old news.

That's where it gets interesting. Skylake-X is a full-featured HEDT platform with up to 44 PCI-e 3.0 lanes and quad-channel memory bus, but Kaby Lake-X is an equivalent of current LGA1151 socket offerings, just in a different package...
Only 16 PCI-e lanes, dual-channel memory bus, limited to TB2.0 and offering pretty much the same I/O as you would expect from the current lineup.


Also, some speculative pics from last summer (source):


...and more...:

This smells a lot like the i5 2550K (2500Ks with failed iGPUs sold at a premium with +100MHz).

Wow, so this makes zero sense. If it was going to be a Skylake-X part, it would be rather affordable i7 entry into X99 like 3820 with X79), but damn, same socket as Skylake-X, just complete suckage compared to it. :shadedshu:

It gets even worse:
according to some sources Intel said that LGA2066 will have a planned support until 2020, at which point it will be replaced with LGA2067.
If SL-x and KL-x comes out Q3 2017, this gives us a little over 2 years of support until yet another new socket arrives....

EDIT: I think I'd rather complete my X99 rig and stick to it for a few years...

This is kind of strange... the specs don't seem to make sense... they might as well sell better binned 7700k and put an X on the box

I hope it has more PCI-e lanes than that! Also, why bother with an i5? I guess a cheaper entry to the HEDT platform? But why bother with HEDT if you can go i5 7600k?

I think you kind of hit on the idea Intel has here.

The high cost of entry for the HEDT platform has stopped a lot of people from going there. If they put out an inexpensive processor that people can start out with, and then upgrade later, it might attract more people to the HEDT platform to start with.

Also, it sounds to me like Kaby Lake-X are just Skylake-X dies that didn't pass QA, and had the quad-channel memory disabled and the extra PCI-E lanes disabled.

Boys, this is old news...

we knew this the past 6 months

is for LGA 2066, same platform as Skylake- X will be on.

Very weird increase on TDP for just 100MHz in clock speed. Could that be that 14nm of Intel's isn't so good in power leakage? Or else, why don't they go up to 4.8GHz for that TDP in order to keep Ryzen's top clocker chips in control? Interesting times ahead for consumers me thinks...

Should be 2066 not 2660.

....I thought I read somewhere that they were gonna unify the lines again. One platform for consumer and High end.

I am all for making enthusiast chips with no iGPU IF they are better overclockers (By more than 100-200mhz) and are priced accordingly. Right now it seems to be leaning more towards they are going to be more expensive which to me leaves me scratching my head as to why. But then again we have no idea if these will be able to hit 5.5ghz on water/air so they maybe a cool offering.

If these are going to be soldered HS like has been rumored, then they should overclock quite nicely (depending on quality of the solder job).

Also, this makes much sense. Cheaper processor to plug into more expensive platform leaves room open for upgrades down the road.


Also also, it's not surprising about the support life for the socket. Remember that even though we're "still" on socket 2011, there's been revisions to the socket that mean only Haswell-E and Broadwell-E work on the latest 2011 socket. Intel only generally offers 2 generations of processor on a specific socket.

Intel is clearly grasping at straws.

Intel's top-of-the-line 1151 chips (i7-7700K, $350 USD) is equivalent of near bottom-of-the-line R5 1400X for i5-7400 price ($182 USD). 1151 is going to get relegated to budget computers because it cannot compete with Ryzen.

NosadaI have no horse in the CPU race, but I have to admit I was expecting more from Intel than this panic reaction. Here I was, thinking they weren't really stagnating, just holding back for the moment AMD offered some semblance of competition. Seems I was wrong.

I don't know what kind of information Intel has on Ryzen, but going by this feeble attempt at thunder-stealing, they at least seem to think they are up against something worth countering.
Preshott p4EE days.

Ad campaign, of course. Intel has always had a fantastic marketing department.

That said, it's great that they're moving some production back to the USA. That's all Trump really needs to give your company time in the spot light.

one wonder ... soooo the i5-7640K is a "just 100mhz more than the 7600K" it was rumored to get HT but does not, right? (thought the only interesting thing is "no igp" ... but the normal 7600K and 7700K should also feature that ... on a i3 and pentium the igp might come in handy but for many user in i5 and 7 nope ... granted it's "imho" )

if yes ... then my 6600K is not even on the border of being in a early retirement candidate ...
when Ryzen will be out benched and if the price is nice ... who know ... maybe (and i would be able to take advantage of the "flock of 2nd hand buyer" who are "intel is teh best" and get nearly 100% refund on it ... or more :laugh: )

socket 2066??? pfahahahahahahahahahahahhahahah ... not even interesting ... good job intel, if you do so ... it's a "shot in the foot"
