Intel Dual Core Performance Preview Part I: First Encounter

semi-Final Words
The verdict on dual core is far from in, but what we've presented here is a start. We have more coverage coming, including power consumption, overclocking potential and a look at the more economical dual core price points from Intel. We're also hard at work on creating new multitasking benchmarks with the hopes of eventually reaching the holy grail of being able to measure and quantify system response time accurately. To that effect, if you all have any suggestions for usage models that you'd like to see tested or any benchmarking suggestions in general, please let us know.
We're far from being able to make any conclusions about dual core or Intel's Pentium D/Extreme Edition, but there are some things that we can say at this point:
- In general use of the system, the Pentium Extreme Edition 840 felt just as fast as the 3.73GHz Pentium 4 Extreme Edition. In multitasking, there was no substitute for the dual core Pentium Extreme Edition.
- Hyper Threading made a decent impact on our usage, even on the dual core platform. However, the benchmarks show that Hyper Threading on dual core doesn't always result in a performance boost. That being said, we'd still opt for Hyper Threading as it just seems to make things smoother than without on the dual core chip. Although Intel has a desire to separate their Extreme Edition and Pentium D lines, we think that Hyper Threading is the wrong feature to use as a differentiator - all users could benefit from its presence on their dual core platforms.
- Intel's pricing strategy for dual core makes a lot of sense to force market adoption. In the near future, we will be looking at Intel's cheapest dual core offering to see how well it stacks up to AMD's similarly priced single core chips. The only way to make sure that developers crank out multithreaded desktop software is to ensure a large installed user base, and Intel appears to be committed to doing that.
- AMD should get an even larger boost from the move to dual core than Intel has, simply because AMD doesn't presently have the ability to execute more than one thread at a time. Intel's Hyper Threading on their single core chips does improve response time greatly as well as improves multitasking performance. For AMD, the move to dual core will give their users the benefits in response time that their Intel counterparts have enjoyed with Hyper Threading as well as the extra advantage offered by having two identical cores on a chip.
- When it comes to dual core vs. single core with Hyper Threading, there's a huge difference. While both improve system response time, dual core improves it more while also guaranteeing better overall system performance. Hyper Threading lets you multitask, dual core lets you actually get work done while multitasking.
That's all for now - we'll have much more dual core coverage later on this week and the next.

Only downside but I think a majorleague heat solution should make everything sweethaveblue128 - Wednesday, July 6, 2005 - link
Oh Please give us a break. If you want to be a purist, go live in the woods without clothes. I say that multitasking makes my day a breeze.Whats your dilemma??

Wow-I just purchased a new sys with an Intel Dual CPU setup. As a multitasking monster on my machine, I was always having crashes in the past.I think that is gone with George Bush in 2008. THe good news is the dual core pair is already hear and ready to run. Give them a try-no downside, albeit a good bit of heat. That is something I will need to work on, but....

I forgot to mention... gentoo linux ;)peufeu - Monday, May 9, 2005 - link
Dual CPUs to compensate for the inept MS Windows.Interesting.
I'm torturing a webserver I just wrote, on my laptop. It's in Python. Right now it's serving about 2000 requests per second with 1000 concurrent connections.
I don't even notice it's running. The CPU gauge is at 100%, so what ? Nothing special. As reactive as usual. It doesn't swap. The harddisk even put itself in standby....
Go, bill, go !

Making special tests just for these processors seems a bit contrived to me. In particular, comparing dual core processors to a Pentium 4 with HT disabled, in a multithreading/multitasking benchmark, is just plane lame.
I would have been a lot more interested in seeing how dual core compares in multitasking vs dual opterons or dual Xeons. Right now it looks like dual core is slower at doing one task at a time, suprisingly not that much faster at doing two tasks at a time than HT Pentium 4s. The only exceptions were the off the wall tests done at the end.
Since these new 'benchmarks' are made to simulate 'real life use', does that mean that all Anand's previous reviews were bogus?

I think I will want one of these for my next video editing & encoding workstation. Will come in handy for HDV post I am sure!BoBOh - Monday, April 11, 2005 - link
Where are the code compile tests. We're not all gamers, some are software developers! :)BoB

I can't wait to see 64-bit dual cores! :)WoodenPupa - Thursday, April 7, 2005 - link
Well, I'm not a tech whiz like everyone else here, but here's my 2 centavos...I can attest to the fact that every machine I ever buy, I bring it to its knees. I usually wait several generations before I upgrade in order to get a more profound effect. Yet that strategy doesn't seem to matter because no matter how fast my computer is, I find that my NORMAL computing habits end up crushing the CPU and everything else.
I use Cool Edit Pro and some other audio programs, and I am also a chess player, and like to anyalyze games in the background with Fritz or Chessbase, both of which allow for gigantic hash tables. So as a typical case I like to do wave transforms and chess analysis as background items while I compose e-mails or use Word for more serious writing. Naturally I like to listen to music at the same time, but usually I have to give that up. Needless to say, all of this stuff cripples my computer---I'm due for an upgrade, I know---my box is a 2.53 GHz P4, 1 GB of Rambus 800 (no groaning, please), a GF4 ti 4600, 120 GB HD, I'm not even sure what the cache on that is, I don't think it's 8 or 5 MB---feels more like 2.
I usually end up quitting the Chess program or the Mp3 player---once in a while I can do all of this stuff concurrently if the wave transforms on cool edit aren't too complex, and I minimize the hash tables on the chess program.
Ideally I want everything to be instantaneous, but...:) Anyway, from what it sounds like, I need a dual or even quad processor setup. Because even with all the above mentioned programs running, I can think of more I would like to add. I'm a monster multitasker and really like to kick a computer right in the face, to show it who's boss. I'm tired of winning, though---I'd love it if one day the computer just scoffed at everything I threw at it. Sadly, I don't think it'll happen in my lifetime.
Should I upgrade to a dual core, or should I save and get a true multi-CPU Mobo like a quad Xeon??
