P4 Hyperthreaded seen as 2 processors? Is this Granite Bay performance #'s?

[DynaOne]

Sorry if this is old - I hadn't seen it. P4 with hyperthreading showing as 2 processors. See some performance numbers in the image. Is QDR Granite Bay?

Yes, hyperthreading will show as two processors in windows XP. No other version of windows (not even 2000) will support hyperthreading, and yes, XP home will support it too.

Granit bay is dual channel DDR not QDR.

Thanks Pink0 - was this a VIA chip set then? (QDR)

All P4's have a QDR Front Side Bus. That's why a physical 133MHz FSB is called 533MHz on the newer P4's (P4B's) and the 100MHz FSB is called 400MHz on the origonal P4's.

are you sure its only xp? and not 2000? its the same thing almost.. i dont want to run xp..

Yes. XP only. Microsoft has explicitly stated that windows 2000 will not have hyperthreading support but that both XP home and pro do.

Yes. That is what the screenie is referring to.

WinXP is the only MS OS that presently supports HT properly.
Granted, you can use and enable HT on Win2000 or even WinNT4, but the OS will view the processor as being two physical processors and will count both against the maximum # of processors supported.
WinXP on the other hand will properly recognize it as being 2 logical processors, but only one physical processor.

And of course with Win9X enabling HT will do absolutely nothing as WinXP won't recognize the difference between a logical processor and a physical processor, and hence will only support one logical processor.

Counting it against the maximum supported is one thing - but will the performance be there under Windows 2000 if it sees it as 2 physical processors? Thanks for all the other answers.

No. According to microsoft it won't work at all in windows 2000. I don't know what he's talking about. I'll try to find the press releases.

Wait a second.... I have Asus P4PE which natively support Hyper-Threading, but I still see only one processor in task manager P4, 2.53GHz. Is that because HT is not supported yet or am I missing something?

your processor doesn't support hyperthreading. It has been disabled at the fab. You will have to get a 3.06ghz p4 if you want hyperthreading.

he he, thanks! I guess I know now what's my next upgrade is going to be ;-)

3.06 with HT + GB = Crazy Benches... Hopefully

me hopes so!

Actually Windows 2000 will take advantage of HT.
The problem is that it will indeed see a HT enabeled CPU as two physical CPU's, so if you have a dual Xeon system and run Win2K Pro on it, only the first logical CPU in each of the physical CPU's will be used, since Win2K Pro is limited to 2 CPUs.

We've begun to see the 2x processor reports as well, turning up Dual Xeon 2.0ghz systems, reporting 4 processors.
