Any Hyperthreading or dual core games?

HT does improve performance. They even gain performance in games that utilize smp patches, look here.

Hmm, well that's surprising.

An 18% increase for the P4 HT is impressive to say the least. Once multithreaded games becomes common I expect P4s to be be much more competitive with single-core A64s.

If you like flight sims, then Falcon 4 Allied Force sees about a 50-60% increase in frame-rate as it is multi-threaded. That is the main reason I ended up going with a dual-core, otherwise not a lot of use for me.

my uncle has the same rig my sig :
but with a 6800GS .
he scored 5040 3dmarks in 3dmark2005 .

afterwards he replaced it with Pentium D 820 .
the scored increased to 5140 , due to the increase in the CPU performance .

but a rather sluggish windos performance .
but excellent multi-tasking performance .

we created a Server on CS:S and then max it with 19 bots .
and norton scanning anti-virus in the background with Adaware scanning for spyware .

no bottlenecks .
but missed the HT until this excellent output .

Peace & ciao !!!

With SMP aware games, P4's can compete with A64's with a couple hundred PR points on them.

Oblivion uses dual core ??? OMG I was already hyper excited by the game, now I know that I won t sleep till tuesday... And then I won t sleep either after that because I ll be immersed in this world...

Hyperthreading of at least the Intel variety on the 478 pin and 775 as well at least is NOT dependant upon programming. contrary to popular belief, it does not take one application or program and run it exclusively on one side and the other on the other side. It takes whatever process string comes to it, regardless of what program it came from and deals it back and forth as they come side to side. that's why you'll see the CPU useage being the same side to side.

Hyperthreading is very flexible but to say that it is not dependent on programming is misleading. If you're multitasking, then yes, you'll benefit a lot from HT regardless of the program. With games you'll also see the same benefit if you multitask while playing. If you don't though, the game must be a multithreaded program for you to see a significant gain. Most games have a few low importance threads (for IO, network, sound, etc) but to see significant performance improvements, you'd need a multithreaded program.

It gives it more than one core of utilization....
I.e.; 2.5Ghz on each core, 5 Ghz collectively...
If the game isn't SMP aware, it'll only be able to utilize 2.5Ghz... If it is, it's like adding another 2.5Ghz to availible usage.

With HT isn't it more like:
2 2.5GHZ or
1 5GHZ?
Because when playing games with HT enabled it reads 50% cpu utilization on each side, disabled it reads 100% on one side.

I just bought a AMD X2. I m interested in performance increase in multiple core enabled games. Have you tried to bench Quake 4 Smartazz ?

Lmao, did you just finish reading the article about the future of CPUS cause your first sentence was almost a direct quote from my post lol. i agree though.

UT2007 is officially slated for a release in Winter 2006. Of course it could be delayed, but knowing Epic Games, it will probably come out right on time as a near perfect game. I am looking forward to it.

HT is more like having a 2.5GHz core and another 500MHz core.

I m sorry Tsuwamono but no i wasn t referring any article in particular. I m just an enthousiast working in the IT field (management) and for me it s obvious that the computing power paradigm will shift from increasing the number of transistors on a core to increasing the number of cores. The next step is for programmers to re-learn their way of thinking, because tasks synchronization will be tricky. But once again, it s just a gut feeling ans I may be entirely wrong.

GalCiv 2 runs the game on one thread, and the enemy AI on another, so should benefit, but not all that much given it is turn based anyway.

Neither. Hyperthreading doesn't give you any additional processing power, it just lets you use what you have more efficiently when multi-tasting. How much of a gain you get depends almost entirely on how inefficiently the processor was being used to start with.
