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.
The argument that HEDT motherboards are more expensive doesn't really fly. You can get X99 boards for under $200. That's pretty equivalent to the enthusiast 1151 Z170/Z270 motherboards at this point. There isn't a massive price difference there.

So it would be very appealing for some that want to get a decent motherboard with the HEDT platform, and then upgrade the processor later on.

Well if there best fight back this year involves a full platform swap some might get pushed AMDs way.

Sounds like a big market that??
It's proper shadey bro.
They should have done a skull canyon style mainstream chip that fits.
Ok so I'd allow an i7 but I5 ,that's little better than a new Pentium , not happening often that imho

Dj-ElectriCHow the hell do you manage to increase performance by 2-3% and screw up a chip's total tdp by 30%+ is beyond me
TDP is the thermal design point. The solder allows a higher target. It doesn't promise higher power usage at stock settings.

FordGT90ConceptAd 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.
They can also just bring over some poor asian bastards and make them work 70 hrs/week for peanuts. This is what they used to do.

That took them a while. "The chips also reportedly feature a high-performance thermal interface material (TIM) under the integrated heatspreaders (IHS)."

The silicone plays a huge roll in stability as does the rest of the power delivery. Quite a few more power pins available in 2066 than 1151.

And its thermal design power? Unless I'm mistaken.

The same was said about Devil's canyon and it was not soldered. I got over 10c temp drop by re-lidding with liquid metal.

Time will tell, if Ryzen is soldered (as is the norm with AMD) and as a result of that and the other stuff it has overclocks well, they may be forced to release soldered models.

I'm sure there is a Visa for that.

If the Kaby Lake-X SKUs could get a L4 128M cahce á la 5775C (albeit with a disconnected iGPU) then it should be a killer gaming CPU.

But, this i just wishful thinking I guess...

Intel CPUs with Iris Pro have that eDRAM cache acting as a last level cache already. The reality is that cache hit rates are already insanely good and that only very specific workloads benefit from the larger cache and it's not like it makes a huge difference. In this day and age, cache and memory throughput is not typically a bottleneck.

I think you mean silicon unless you wanted this discussion to take a turn for the worst. :p

It's not a new guide, just another version bump to a very old guide. ;)

True, I got my X99 board for $159 back in November.

Replace iGP with 2 more cores on the mainstream platform and then we are talking, but its not that simple unfortunately.
