A Prestonia (Xeon .13 with Hyper Threading) Demo!

[Athlon4all]

VH found some shots of a Prestonia demo, go see em here!

Now we'll have to see if HyperThreading will make a big difference.

Is this a P4 Xeon or a P3 Xeon (I'm guessing a P4).... Also, what is hyperthreading?

A good simple explanation of HyperTheading can be found here: http://www.maximumpc.com/features/feature_2001-08-28a.html

HOw do poeple manage to crap these new stuff?

Cool 😎

Does anybody know if W2K and XP will have to be recompiled to take full advantage of this, or will it work out of the box? Clearly SMT ops have to be handled differently than SMP ops. Man, this could push the need for IA-64 out even further. I'm sure Intel is loving that...😉

Cool 🙂 They're running W2K on it too, wonder if some kind of service pack was needed to make the config recognizeable.

 

[ViRGE]

While I'm sure XP and probably 2K will be tweaked to really take advantage of it; as far as I've read into it, it can currently still be used as the OSs will use it like a 2 CPU system.

Since Hyperthreading occurs in the CPU - the system wouldn't need to be tweaked, right?

"This would give Hyper-Threading PCs an advantage over today's dual-processor machines, which require that applications be specifically written to take advantage of multi-threading. "

W2K and XP will work fine right out of the box because their SMP aware. If your using two SMT enabled procs you'll need a OS that can handle four processors which means you have to use Win2k Server, Win2k Advanced Server, Win2K DataCenter, Unix or BeOS.

Hmmm...talk about processors choked for bandwidth. That means that all four "processors" will be sharing the same bus...unlike the EV6 bus. Even with PC1200 things would be tight. Of course by the time this works its way down to the desktop P4 we'll have PC1600+.

You left out the line right before this one that gives you your answer:

"Intel says Hyper-Threading will require optimization of applications and operating systems to take full advantage of the technology. Jackson, in theory, will work with even single-threaded applications."
