1 CPU That Runs Like 2?

ZDNet has some news on Intel's new chip technology called Hyper Threading. The new technology could allow for 1 chip to run almost as effectively as 2 by using idle registers inside the Pentium 4. Here are some details:
Technically, hyperthreading takes advantage of additional registers--circuits that help manage data inside a chip--that come on existing Pentium 4's but aren't used. Through these registers, the processor can handle more tasks at once by taking better advantage of its own resources. The chip can direct instructions from one application on its floating-point unit, which is where the heavy math is done, and run parts of another application through its integer unit.
Although still in it's early stages, an Intel tester has managed to gain a performance of 30% on a Xeon workstation. The ideal enhancements would allow computer users to easily multitask while running CPU intense programs. Read more here.

That article is a laugh and quite a bit of spin by Intel.
No wonder the Athlons outperform P4s at dissimilar speeds. Intel is trying to get the developers to use the "new" registers in the P4 that deviate from the i386 architecture. So, if they optimize their software for the P4, the software won't run on a P3 or AMD CPU.
They are calling it hyperthreading. Jeez... Programmers were doing that long ago on the Motorola 68xxx series of CPUs with its extended registers.
Hyperthreaded chips would also be cheaper than dual-processor computers. "You only need one heat sink, one fan, one cooling solution," he said, along with, of course, one chip.
ROFL
Quit it! Quit it! I can't get through reading the rest of the article!
Computers containing a single hyperthreaded chip differ from dual-processor computers in that two applications can't take advantage of the same processor substructure at the same time.
OMG! When could two applications ever use the same substructure on a single CPU?
Kdr Kane gets up off the floor.
"Only one gets to use the floating point at a single time," Poulin said.
Only one application? duh!
Kdr Kane falls back down on the floor.
I have to give this round to AMD. They are simply optimizing their CPUs better, versus Intel trying to ram another non-standard down our throats with a lot of spin.
Let me make a suggestion. Don't ever optimize for a P4. 64-bit CPUs will be here before the ink dries on your box of software.
They must be getting these spin doctors out of high-school now.

Oh boy, that was a good laugh! You want something that does true multitasking? Get an Amiga from the garbage bin!

I think Intel will take even more of a beating when they introduce their 64 bit processor. I hear it doesn't perform all that well on current 32 bit apps.
The Hammer however is supposed to operate both effectively. It will probably be slower on the 64 bit stuff than Intels offering, but I think most businesses would rather have their current applications run well as well as be able to run 64 bit applications.

Yeah, yeah, it's shakey...
I don't like to put negative comments up on the main page, so I try to only give the facts. Don't kill the messanger!

TR,
Wasn't aimed at you. I try to not comment on my news posts too much, also. I do some, but it makes me uncomfortable.
Actually, I had just drank a beer and the news item seemed hysterical. Still does.

Okay
Funny watching the silly steps AMD and Intel are taking to try and best each other.

Yes, it is quite entertaining. Did anyone bring the popcorn?
