P4 HT

[Daniel Siemens]

They work well.   Most kernels that I have played with will load up the
SMP kernel and treat the system as a multiprocessor system.   I don't
know if HT makes a big performance benefit.   I never did a timing with
HT on and with it off on the same system.

Subject: P4 HT

This is just a curiosity post. Has anyone had any experience with Linux
with a P4 HT processor? Is the thing pretty much the same as a "regular"
P4?

I have a old P3 running on what I think is a 100MHz board, and tried to
do some video capture from a DV camera (kid's 5th birthday). The capture
was crappy - dropped a bunch of frames and left the video choppy. So, I
read through the sys reqs and figured now would be a good time to
upgrade.

I went shopping today and ran into the P4 "HT." The salesman (working on
commission, of course) really talked it up and said it was the one for
me. The way he explained it made it sound like the processor worked
differently than other (older) P4s - something about the older P4s using
half the processor for "check sums" or something like that, and the
other half for actual processing. This P4 HT, then said he, used all of
the processor for processing, yadda yadda yadda... 

Pricey, too. $267.00 (US), just for the P4 (no motherboard, RAM or
donuts included). 

So, I'm kinda curious, and therefore will undoubtedly read a little
about
the HT. But, I thought I'd post to see if anyone is running one of these
things with Linux. Does it work okay?

Thanks.
