Intel to bring back Hyperthreading with Nehalem core

[Xero (1)ne]

Things will get a bit more interesting with the introduction of the Nehalem core - an evolutionary step up from the Core microarchiteture. Sources said that the Nehalem architecture will result in performance gains in the range between 20 and 40%. The architectural changes in Nehalem will bring new instructions as well as a new shared cache, which, according to sources, will grow to 12 MB. Intel will also revive its Hyperthreading technology, which will be called "symmetric multi-threading" (SMT).It basically represents a multi-core adaption of the original Hyperthreading idea that was first introduced with single-core Pentium 4 processors in 2002.Source: http://www.tgdaily.com/2007/02/13/amd_intel/

To be clear, despite some reports I've seen Penryn will not have HT on it. If Intel does use HyperThreading again it won't be until their Nehalem core in 2008.

Sheesh, a 12mb cache on Nehalem? Better have those skillets & eggs ready to go! 20-40% improvement in performance or not it sounds like another hotplate. With any luck the new dielectrics, lower process node, and change in materials used will lower the heat generation down to match...

HT was a bunch of bull, whats next Netburst? :rolleyes:

HT wasn't bull... Infact I oughta know because the computer I am typing this up on uses it. ;)

There is something to be said for using a single core CPU, but getting the feel of a dual-core system. No lagged out system when programs are busy, for instance...
