Just a question on the new conroes

[ChRiZo]

As good as they are, are they hyper threading? If not.. why?

[Macaholic]

No HT. More about it here (http://www.theregister.co.uk/2005/08/23/intel_next_gen_architecture/).

[ChRiZo]

Ah, i see. Imagine if it did though..

[nd4spdbh2]

yes but who needs dual cores with HT... when you got a kentsfeild :beer:

[Vipasnipa]

Heh, imagine a Kentsfield with HT. 8 threads anyone?

:drool: :drool: :drool: :drool: :drool: :drool: :drool:

Lets see what happens.. who knows.. intel is unpredictable.. :)

[White_Pawn]

is kentsfield supposed to have HT? or is it going to be reserved for 45nm cpus?

[greenmaji]

HT works better on longer pipeline CPU's, that would be why they arn't using it.

Only works with applications that use HT. Otherwise, It slows everything down. HT is a virtual CPU. Please correct me if I'm wrong....

What I find funny is that Dell sold P4's with HT on XP home boxes... Now thats just stupid!

why is that stupid? xp home works just fine with HT. :)

Well, I'm getting a Pentium EE 965 within a week here (for free) so I'll just drop that into my current rig and be happy, 4 threads is enough for me :D

how long have you been talking about this FREE 965? are you ever going to actually get it? :)

[greenmaji]

IDK if I want to hear about it :rolleyes:
"I'm getting a 965D" is cool.. but how you got it.
I know that doesn't matter to me.

XP Home supports DualCore\HT. I use XP Home on my home machines.

Ummm...XP home cant see multiple CPU's... Single only...

EDIT: Found this information


While Windows XP Home does not support more than one physical processor, there's a lot of confusion about whether or not it supports multiple processor cores in a single physical processor. This is implemented in several ways, of which the most widely used is Intel's Hyper-Threading technology. Also, AMD is currently rolling out a series of 64-bit processors called the X2 dual core series, which features two processor cores per die.

How much of this is supported? The answer is all of it -- in XP Professional, and, surprisingly enough, in XP Home as well. If you install XP Home on a system that has a single processor with dual cores or hyper-threading (what is referred to as two logical processors—XP Home will recognize both of them, and will install the appropriate Hardware Abstraction Layer (HAL) to work with it.

However, if you have more than one physical processor (such as two dual-core or Hyper-Threading processors), XP Home will only recognize the first one. Note: If you enable hyper-threading on a machine on which Windows is already installed, the HAL will be automatically upgraded (if it hasn't been already) and you'll be prompted to reboot a second time to finalize those changes.

Microsoft's official word about multiple processors across all its products is that they are licensed by physical processor socket, not by the number of cores on each processor. For instance, if you buy a single-CPU license for SQL Server 2005, that license is valid no matter how many cores are in that one CPU. Likewise, Windows XP Home will only work with one socket at a time regardless of its cores or threading potential, and XP Professional will recognize up to two sockets.

Interesting...I was right and wrong...
