Intel's 2007 guidance outlines the projected volume of each SKU by the end of the year

Intel's latest partner guidance revealed the shipment numbers it projects for 2007.

Two immediate things jump out for desktop projections: by Q4 2007, more than 85% of processor shipments will be at least dual-core; and by Q4 2007 the company only expects 5% of its desktop shipments to transition to quad-core.

Not only will dual-core take the center stage by Q4, but the company's guidance is also very clear about removing all 90nm SKUs before then as well -- no more Pentium D, Pentium 4, or Celeron D.  This means there will only be four major components floating around in the channel and for OEMs: 65nm quad-core processors (Core 2 Extreme and Core 2 Quad), 65nm dual-core processors (Core 2 Duo), 65nm single-core Pentium E2000 and 65nm single-core Celeron 400.

All of these processors are in some way Conroe derivatives.  This is a large departure from Intel's 2006 channel where we had some 65nm Cedar Mill and Presler processors, a few 90nm Prescott and Smithfield derivatives and all the Core 2 Duo SKUs.  2008 will really be the first year in several where Intel will only support two generations of processors: Penryn and Conroe.

Intel's guidance expects approximately 5% of its Q4 2007 desktop market to transition to quad-core, approximately 70% to transition to dual-core Core 2 Duo, 20% to transition to single-core Pentium E2000 and the rest to fill in the single-core Celeron 400, which is really just the same as Pentium E2000 with half the L2 cache.

For the mobile business, the transition guide is much murkier.  Intel's guidance suggests that the company will even support the 90nm Dothan CPU in Q4 2007, though Core 2 Duo will assume 90% of the company's mobile volume by that time.  The rest of the market will fill in with legacy Yonah processors.

Intel's guidance for Q4 2007 on servers is also very clear: the company expects a 70-30 split between quad-core Clovertown and dual-core Woodcrest.  Where quad-core will only consume a small portion of the desktop market, the server market will be almost entirely dominated by quad-core.

IF you dont believe me just a program you know to be single thread and watch how both cores shoot up to same number.

No it doesn't, I've got a Pentium Extreme Edition 955 in my second system and you can fully load one core and one core only. Actually try it out before you talk.
Hyper-threadings MAIN advantage with Netburst chips was in helping compensate for pipeline stalls by quickly bringing a second thread in rather than wasting clock cycles but in specific cases it could run 2 threads simulataniously, albiet not in the same manner as 2 discrete cores (each thread had to only using a certain amount of instruction resources).

Also pretty much no program uses only one thread, unless you want the GUI to freeze whenever you do ANYTHING.
Turn on the Threads column in Task Manager (View, Select Columns).
Right now Steam is sat idle and has 35 threads, the Vista Sidebar has 15, my IRC client is using 11, 43 for MSN Messenger. Even a Java application displaying "Hello World" uses 9 threads for the virtual machine alone.

The thing is these threads are all relatively 'light', they sit waiting and when they come into action don't take much CPU time, and its these that HT can run together. Compare a Pentium 4 to a Pentium 4 with HT and you'll notice the HT is slightly quicker to react to mouse inputs when the system is heavily loaded (eg. clicking the Start menu while running Prime 95).

As the number of execution units increases (such as in Core 2 with a 4-issue core, as opposed to the 3-issue of Netburst or K8) then Hyper-threading could show more benefits.
