Skylake i5.... no Hyper-Threading?

Leadfingers · Aug 6, 2015

If I understand correctly, the new Skylake i5 doesn't support Hyper-Threading.

Am I correct? This seems really odd to me. Why would they brain-damage a brand new CPU like that?

i5s dont support hyperthreading, thats the point of the i7.
I dont see this changing any time soon.

I5s are supposed to not have hypertheading. If they did then the i5 would be identical to the i7.

So if you want a i5 with hyperthreading, get a i7.

Is that a new thing? I thought all the other i5's had HT...

No, all desktop i5s lack hyperthreading.
To my knowledge, there was only a single hyperthreaded desktop i5. http://ark.intel.com/products/53448

The only desktop i5s that had hyperthreading aside from the one mentioned above were the Core i5 6xx series, which were basically first generation i3s with slightly higher stock clockspeeds and Turbo Boost enabled eg. dual cores with hyperthreading. All laptop i5s have hyperthreading as they are dual core CPUs. Desktop i5s are always with the exception of those mentioned above quad cores with no hyperthreading.

Like supernova1138 mentioned, aside from a couple rare cases the only i5's with ht are the mobile lineup for laptops and the ones with ht are dual cores so more similar to desktop i3's. Sandy bridge, ivy bridge, haswell, haswell refresh, devil's canyon, broadwell and skylake are all straight quad cores for the i5 and hyperthreaded quad cores for the i7's. Depending what you do depends how useful hyperthreading is or isn't. So far the initial skylakes being released are the i5 6600k and i7 6700k with no mention of the 2c/4t i3's which may come later. Haven't heard much about i3's for skylake but haven't heard any news that they're ending the i3 line either. It's a bit backwards this time, usually they release the lower clocked/locked core cpus first then release the unlocked performance chips later. With skylake they opted to release the unlocked chips first. Efficiency and performance are up a bit but so far overclocking results look very similar to devil's canyon.

Supernova1138 :

I forgot about the 6xx models, they came way before I got involved with computers.

Gam3r01 :

Yeah all thru the years there have been select few i5s from Sandy Bridge, Ivy Bridge, and Haswell that were dual core with hyperthreaded. Reason being their TDP was only 35W.

I have this laptop,
Lenovo Thinkpad Edge E430 (3254-N2Q)
It have Intel i5-3210m and it have Hyperthreading.

Laptop cpu's are completely different
