Intel Skylake-X, Kaby Lake-X Leaks Vs AMD ThreadRipper 'TBD': Fun Summer Ahead

[TJ Hooker]

One thing that really makes me raise an eyebrow over these specs is the lack of hyperthreading on the 7640k. In the past, Intel has always used the i7 label to indicate hyperthreading, so this would be a big departure from their usual branding.

Lets be honest the whole 4-core with and without Hyperthreading in the HEDT lineup for Intel is goofy especially since there is almost no way anyone can saturate the quad channel memory with a quad core CPU anyhow as its like a .001 niche.

According to the table both i7s will only support dual channel memory. The 7740K and 7640k seem to be identical to the 7700k/7600k except for slightly higher base clocks and the fact that they're on a HEDT platform.

Hmmm... so Tom's is getting into the rumor mill business? You guys were one of the last hold-outs.

Anyway, FYI AVI-512 isn't one feature. They subdivided it into 11 features, with different groups of them potentially appearing in different SKUs and market segments:

The 7740K and 7640K don't make a ton of sense to me. What's the advantage over the 1151 processors? Or is Intel simply trying to lower the bar of entry to get upgrade-minded folks to buy into X299?

I think that's exactly what it is. For someone buying a new system once KB-X is out, they can either go 1151 and max out at a dead-end with the 7700K, or go 2066/7740K and have a similar (barely better) system that has a clear upgrade path. Honestly, I'm not sure how many people that will apply to, but that's the only reason I can imagine.

I agree with this, mostly. I was mystified when I first saw rumors of Kaby Lake-X being nearly identical to i7-7700K.

However, you're forgetting one thing: overclocking. Traditionally, the Socket-2011 CPUs have a soldered IHS. This might create a bit more overclocking headroom, especially for those too timid to de-lid or use direct-die waterblock cooling (both of which are a pretty small minority of i7-77xxK buyers).

Yes but its pretty lame Intel didn't just solder the "K" series CPU lids to start with. Now you have to pay a premium for something that should have been done in the first place. At least AMD soldered all there Ryzen cpu lids thank goodness.

Well, right now the 6950X is on sale for only A$1399, about US$1000...Only 3 remaining, mind u
