Wow those are two VERY confusing links.... A 2700+ running @ 3.3ghz????!!!!! ...and a P4 2.4 that has the HT enabled in the MOBO bios does not mean that HT is enabled in the cpu itself..... :confused:

Hmmm...I'm not sure about the HT thing. While I would normally expect VR-Zone to know their stuff, I've heard from several sources (including our own WingzNut) that its not possible to enable HT on existing CPUs - even if Sandra says you have. So, I'd basically need some benchmarks showing a performance difference to believe it. Thanks for the link tho :)

I agree. The P4 with HT is kinda, well yeah OK, how did you do it? That would be helpfull...

In order for HT to work....u need:

1) HT mobo (Asus P4T-533c w/1008c bios is what I have and it is HT ready)
2) HT cpu (Intel P4 3.06 < is only HT enabled CPU's period)
3) HT OS (MS WinXP pro is what I have and it is HT ready)
4) HT supported apps (It is questionable and argueable if any at all software exists today that is HT programed)

Actually I think it just needs the apps have support for multi-processors, since it will just 'see' it as 2 cpus

No HT needs more than just programmed apps, without platform support, cpu support, or OS support, HT will not float beyond a question of any doubt...

Well, I also have Item 1 and 3. I doubt it that I have Item 4! and I definately don't have Item 2. So I wonder what VR-Zone is on about. I do recall however that it was rumored that P4 (B) CPU's had HT integrated within, just not activated.

"I do not, have not, and will not work for Intel Corp." :p

I don't know how they might have done that with HT unless the Pentium 4 was an engineering sample.

But you definitely do not need threaded apps to take advantage of hyperthreading - you just need multiple threads. Ideally, you want the one program that you are working on to thread itself - ie. hyperthread enabled - but if that's not the case, then you can still see some benefit by working on two different threads from two non-threaded programs in parallel. For example, listening to MP3's while playing a game. Or downloading something from the internet while watching a movie. If you are only doing one thing at a time, then this may of less use, but I know that on my computer I am frequently doing several things at once (burning a CD while downloading something from the internet while listening to NPR on Real Audio while playing a game).

Patrick speaks the truth. What I was trying to impress upon others is that apps, in order to see the FULL benefit of HT, will need to be coded to take advantage of HT...

If a certain individual had an HT cpu, an HT mobo and bios, and an HT OS, then he or she would see improvemnt when they have multiple non HT coded apps running @ the same time as the OS would be juggling these non HT apps much more efficiently than without HT

Apparently, this P4 2.4(B) CPU @ VR-Zone was indeed an Engineering Sample. :(
