Why would intel make Skylake-E, when they could just skip to Kabylake-E?

[unseenmorbidity]

Kabylake is basically a refresh of Skylake with the only real difference is the fabrication process, so why would intel even bother using an inferior process?

Skylake-EP is manufactured in 14nm+.

One new bit of information that Intel confirmed at the SC16 press briefing was that Skylake-EP will utilize the 14nm plus process introduced first with Kaby Lake. Intel claimed improvements over the original 14nm process so it is great to see this technology utilized on Skylake-EP.

ty. So, will this mean they will skip kabylake-e?

There's nothing to skip. The parts that make Kaby Lake different from Skylake would not pe present in HEDT anyway. You're just hung up on marketing names.

Skylake-E is already using a different core to Skylake. It has stuff like AVX-512 units.

I knew it was slightly different, but that doesn't really answer my question.

What would differentiate Skylake-e and Kabylake-e? Wouldn't they end up being nearly identical CPUs with a nearly identical level of performance?

Kabylake uses the Skylake core and has a slightly updated media engine. It's built on 14nm+.

Skylake-X/EP/EX are based on the Skylake Server core and are built on 14nm+. Kaby Lake-E would just be Skylake-X.

Kaby brings an improved IGP with 4K-netflix ready DRM to the table. HEDT dont have an IGP so nothing of value is lost.

The situation is different this time from previous HEDT platforms. Up untill Skylake Intel used idetical cores in both its server and desktop CPUs. All in all Intel had just 4 different cores in all of its products. We all know intel core series and atom but let's not forget about quark and itanium. I even read that Intel still hasn't abandoned itanium completely and a new itanium CPU codenamed Kittson is to be released in 2017. To best explain why there won't be a kabylake-e and why it would only differ in name to skylake-x we should first ask what is kabylake? Kabylake is basically a skylake on 14nm+ with an updated GPU. Skylake-x is already made on 14nm+ proces and it doesn't have an integrated GPU so Intel could just as well call skylake-x a kabylake-e and it would be just as accurate as it is now.

Skylake-EP is manufactured in 14nm+.

Let's hope not, the 14nm+ process seems a step backwards, despite your own beliefs.

It's measurably not a step backwards in commercially available products.

Kaby Lake on the other hand is more than just a simple rebranding of the Skylake chips. Even though the 14-nm process was basically not changed, the manufacturer was able to optimize it considerably. The results are surprisingly high clocks or a much lower consumption at the same clocks, respectively. Depending on the frequency range, we can see efficiency improvements somewhere between 15 and 25 percent; it remains to be seen whether the lower clocked Core-m/Y-series might be even better. We are also eager to see the quad-core ULV models. They are planned for 2017 and should introduce the biggest performance gains in the 15-Watt segment we have seen for years.

It has been confirmed that Skylake-EP is built in 14nm+, which means that Skylake-X will be, too

All indications are its an improvement. I assume you are referring to the fact that 7700K clocks higher but uses much more power than 6700K.

We are pretty much at limits of CPU technology. Getting that 100-200MHz out will take a lot. The fact that 14nm+ does it at all at that frequency tells me its pretty good. In laptops Kabylake achieves a decent gain with minimal power increase.

How in the world can you think it's a step backwards? Even discounting the IGP advances it's clearly a small step forwards, which is exactly what it was always supposed to be.
