Intel's 2 in 1

Wait.. are they saying that Willamette has SMT support built in already?...

Doh, no periods again!

bleh

Does anyone have a link to true technical details ?

2 Pipes is not gonna give ya twice the multithreading performance, you need to duplicate the register set and whatnot. I mean, there's no way they have 2 whole CPUs on the P4 die... so, they put in a few more circuits to build a small part of a full CPU and that will eliminate some tasks that need to be done on a standard single system when switching tasks.. right ? So they might optimize task switching which *is* good, however, the press release and the explanations are for 3 year olds. Also,

I've been running 10+ apps at all times for years, 's called multitasking. DOH !

booyaka

Intel innovation

HA, skimming the article it looks like they've just added duplicates of some parts of the chip to provide a sort of pseudo second proccessor. The idea of two CPUs on a single ship has been around for a while, in fact I believe IBM made a prototype of one some time ago. GG intel, and fire thoes bozos in your marketing department already.

"An individual could play games while simultaneously downloading multimedia files from the Internet with a computer containing the technology, Poulin predicted."

Isn't that what many of us do anyway? :D

--Valiance--
but not multiplayer games, lag = sux0r

Maybe they'll processors will eventually be as fast as AMDs with same clockrate..nah!

Sorry Intel... AMD 4 Life

what an amazing news post

This is why I dislike posting on Shacknews, the age level is about 12 years.

Jackson is multi-threading. When you have a dual CPU system, two threads can be executed at once. This does not mean a program runs faster by itself, only that TWO programs can be run at once without a significant performance penality - because each program has a CPU to itself, and they won't interfere with each other. In other words, each thread can have 100% CPU time, instead of 50% each on the same CPU.

In a nutshell, Jackson can execute two threads at once with just one CPU because Intel has somehow managed to split the pipeline into two logicaly seperate pipelines. Now, this does not magically create more than one CPU, but a program that can multithread (like my MPEG encoder) can take advantage of Jackson's ability to perform two full calculation strings AT ONCE, which is much faster than using the whole pipeline for a single transaction.

In practical terms, you would be able to perform two CPU-intensive tasks with little or no loss in performance in either. You could play Counter-Strike while encoding a DiVX with no problem.

lol
i played ra3 for 1hr and a buddy sent me an iso image.
i was playing then when i finished it was magically there!
2 in 1 huh.
lmao

"You only need one heat sink, one fan, one cooling solution,"

yeah, as if the most significant cost of a dual proc system is the goddamn fans. bullshit.

Intel gave a speech at my school a few years ago - they claimed that about 30%-40% of the price of a boxed Intel chip is the heatsink and fan. And that's why they're so expensive. Yeah, sure, we believe you, Intel.

An individual could play games while simultaneously downloading multimedia files from the Internet with a computer containing the technology, Poulin predicted.

isn't that called "multitasking, or did some marketing person change the buzzword to hyperthreading without notifying anyone?"

Hmm.. Unused Circuitry? Didn't anyone click on this? WHAT unused circuitry.. why are they putting in transistor logic that they didn't use previously? I never knew chip manufacturers made the die bigger then necessary, to keep costs HIGH of course. I guess the claims that the P4 is a half-backed next-gen chip that's overclocked to get performance is true.

Yah, and seriously, what a LAME example of multitasking. Who'd want to play games and d/l anyway when that could bring you down from 120fps to 111fps !

So are they promising TRUE multitasking with this? Or are they just trying to make it sound like true multitasking when it's really just the same old preemptive multitasking, only a little bit faster?

"An individual could play games while simultaneously downloading multimedia files from the Internet with a computer containing the technology..."

That's one of the most retarded examples of CPU technology I have ever heard.

yay! Go Intel! heh

This isn't just some marketing hype. For a while now, chip companies have been looking into on-chip multi-threading.

Most modern processors are designed to run multiple instructions in parallel, yet whether they're able to do depends on whether the thread they're running is amenable to parallel processing. If the thread is not amenable, then the parallel execution capabilities of the processor sit idle. In general, this happens often enough that modern processors are usually running far below their optimal efficiency.

On-chip multi-threading tries to alleviate the problem by instructions from multiple threads to run in parallel, thus significantly increasing the efficiency of the processor.

The next generation of Alpha processors are slated to receive a form of mult-threading called symmetric multi-threading, or SMT.

It is unknown whether what Intel's doing is true multi-threading and SMT in particular. If you have the stomach for it, you can head over to the technical forum at www.aceshardware.com where people who are much more technically knowledgeable than I am are debating the issue.

Yeah, and I bet that using hyperthreading conveniently de-optimizes for Athlon and Pentium III.

eat shit and die

sometimes I wish I was the average mook so I could be all "WOW! How's dey do dis hipershreading!" when this crap is fed to me.

I already have SMP. I don't need this boocrap.

[revolver]

Hardware multitasking?

(Yeah, and the CPU won't be waiting on I/O, etc, etc etc)

Intel sez: UR IntERNAT wEll g0 400X FasTar w/ PENFIUM 4!

Holly Nvidia!
