I haven't read much about the intel cpu's.. but I had thought that hyperthreading was something along thelines of a duel core cpu.. Do you need a multi threaded application to get better benchmarks for a hyperthreaded cpu? What the the differences..?? advantages of either in a gaming environmet?

yes you do need a multithreaded application. In theory if you have a 'single thread' application it will produce the same benchmark score on a single and a dual core cpu (of the same GHz).

Dual core is very similar to hyperthreading. They differ where hyperthreading splits the cache on the cpu in half and assigns half to each processor. Proper dual core CPU will each have their own dedicated cache.

The processors are also addressed differently (complex to explain).

You can also get hyperthreaded dual core CPU, giving four logical processors. I believe would req four threads to see full performance.

Basically hyperthreading gives a small speed increase (5-15%) and dual core should give a much greater increase (80-90%).

At the moment dual core and hyperthreading is totally useless for gamers, as no games support more than one thread. But once people start buying dual core, the games will arrive.

Watch out for Microsofts XNA. It will undoubtably produce multithread games.

p.s. Games are mostly graphics card limited anyway. Then next big thing game-hardware wise will probably be physics processors.

It'd be nice to see usage of dual-core processors in games - one for physics, one for other things (AI routines, etc). Would that even be possible?

any thing is possible. that would be great if they did that thoe. one goes for phyics and other for AI.

Forget that man, physics processing cards are coming on the horizon....i wanna see them pci-e lanes filled up for more than jus my soundcard and my gfx card(s)....

Ive snapped:
An xbox360 and a 12" iBook....
And a kawasaki er-6n to mod instead

I'm sure there are some games out there that are multi threaded... Quake III comes to mind, but I've never heard of it being any faster/better with dual cpu..

A friend of mine loved having dual celeron 366's.. as he had a dual head vid card, he could watch a DVD through tv out, have an mp3 playing through headphones, and play half life on his computer monitor without anything ever having a glitch... It was really impressive at the time!..

I think the author is right that dual cores are clearly the future but wrong in that Intel will maintain control. This time, AMD has Intel's ticket punched.

If you check out the reviews of the dual A64x2 and the Opterons (like @ anand) the multi-tasking performance of the dual AMDs is simply amazing. In many of those tests, the dual cores maintained 90+% of their single thread tasks when playing games and running other significant apps in the background. That performance was head and shoulders above Intel's best.

The Prescott was underwhelming as a CPU, but Intel leaveraged its goodwill to sell millions of them, and that is in large part due to Intel's domination of corporate sales. With such a huge performance lead (and a significant price advantage when you consider no new motherboard is required for AMDs), I think AMD will finally win over the IT crowd. The masses will follow.

Yeah, the Athlon 64/Opteron were designed from the start to be dual core ready, while the Prescott wasn't. Plus heat is a major issue with Intel. If Intel could say make a dualcore 3.6ghz processor, well then that might be something. With a higher FSB 1200mhz, then that would be nice. But they can't. Heat limits the clock and the FSB is limited by who knows what.

Actually, I heard that AMD's duel core CPUs are designed in such a way that single thread apps will actually benefit. I don't think this will hurt AMD one bit.

Hmm single thread apps work fine....a 2.4 ghz dual core with 512 kb cache performs like a 2.4ghz 512kb cache single amd 66 should work.....since you pay considerably less for the 'second core' its quite good.....except its called an amd 4400+ and its outperformed by the 4000+ in single app:p


Hhough whiole running stuff in the background its whups the top intel extreme edition dual cores ass.......yay! only one benchmark did intel win! yay though 1001 dollars for the 4800+ is a bit odd....but a nice change from X99.95 dollars

I'm lookin' fwd for the reviews... We'll see a lot of advertisements for water cooling systems, hyper-vented cases and a lot of other gizmo's to keep that Intel dual core within reasonable temperatures... ( i was gonna say "in idle" but don't want people to accuse me :P )
So for now...the question for me, as end user and person not willing to spend huge amounts of money, still remains: "Why buy Intel's hot stuff, single or dual core, when the AMD doesn't force me to go buy the top cooling solutions?"
In the end, the masses (so to speak) don't spend on the latest models, but go for the best prices...am I wrong? And turning down the prices on the Intel doesn't turn down the requirements in cooling..

Alright, after some delay Intel shipped us a 3.2GHz (840) dual core processor and 955 chipset motherboard, before I let her go on a standard set of benchmarks that'll not do much for dual core, I'd like for you to tell me what you'd like to see. Keep in mind that we don't have time for elaborate testing schemes, as we're out to see if dual core can prove its worth on the desktop.

If you have any suggestions feel free to post them in the below thread, or email me directly at ssassen@hardwareanalysis.com.

Dual core benchmarking, we'd like your input
