i dont know if this is a good idea, but i think it would be nice, to list Aplications and Games that suport multi-cpu.
why ? because it will be easier to people to know, with what Aplication they will get more performance with dual-core or dual-cpu system.

-------------------------------------------------------------------------

Aplications: Virtual dub , 3DSMax , Cinema4D: Cinebench 2003 , Xmpeg , TMPGEnc Plus , Vidomi , Mp3 Maker , GoGo MP3 Encoder , Windows Media Encoder, Adobe Premier , Visual C++ , Real Producer Plus , Maya , 3D Studio Max , Cine 4D , Truespace , KribiBench , AutoCAD , XSI , Lightwave , Adobe Photoshop (tnx to deathman20) , POV-Ray , ScienceMark ,

one list: http://www.denniskarlsson.com/smp/

-------------------------------------------------------------------------

Games:
Unreal Tournament 2003
Unreal engine 3 (2006 release date)
Quake III Arena
Wolfenstein: Enemy Territory



-------------------------------------------------------------------------


and it would be nice, to see what benefit it is from one to dual....
i cant test now, cause i dont have dual-cpu system.

ps: more apps will be added later.... this is only the begining...

ps2: the thread will be organized better...

ps3: THIS IS NOT A CPU - WAR THREAD, so please respect every one...

Almost all 3D Software packages benifit from it. 3D Studio Max, Maya, XSI, Lightwave, and some other ones. Also video composers use dual cores as well Premire and Combustion. Don't know of any others. But doesn't Photoshop utilize dual cores also?

There is quiet a bit of them that due support it. Server grade apps are a biggy.

Raw Divx encoding is largely a function of bandwidth and here we can see the double width CPU bus of the Dual Athlon system keeping it neck and neck with the Pentium4 system. The other systems struggle to keep up.


This is all good stuff but how about a real-world test? To simulate a realistic test we added a neutral bicubic resize filter in the .avs file and used the following CODEC parameters (including two popular Pro settings) which are designed to total 700MB (when the audio is muxed in):

The addition of computationally heavy filters put less emphasis on the memory bandwidth and more on raw CPU speed, changing the situation dramatically. The Dual MP2600+ is well in the lead due to the extra processing required for the filters and Pro settings making this the best Divx encoding machine we have reviewed so far.

Real Producer Plus: from developer:
karl_lillevold:
Re useThreads : With regards to hyper-threaded P4s : I detect this, and actually disable threading, due to cache contention causing slightly lower performance with two codec threads on hyper-threaded systems. True dual CPU systems rock though, almost twice the speed of single CPU systems.

Multi-Processing test:For this test we run Windows Movie Maker and Windows Media Player at the same time.

The workload is multitasked where Window Movie Maker encodes a DV-AVI video to a MPEG-4 Windows Media VIdeo 8 format while Windows Media Player plays a 57 second WMV 8 file. The input video is a 208MB DV-AVI. The encode rate is 768kbps, 320x240, 30fps. Prior to starting the video conversion and benchmarking WMP is started and set to high priority in Task Manager.

As in tests of this kind the shortest bar is the winner and here we can clearly see that the Dual Athlon system is clearly superior. Analysis shows that Hyper-Threading gives the P4 3.06GHz a boost but is nowhere near as good as two actual CPUs.

Multi-Processing Test 2: For this test we ran MusicMatch Jukebox 7.2 and the Novalogic Commanche 4 demo at the same time.

The workload for MusicMatch Jukebox 7.2 encodes into mp3 format a .wav file which is about 600MB. The .wav file contains about 60 minutes of music, has a 1411 kbps bit rate, 16-bit audio sample size and 44KHz audio sample rate. This .wav file is converted into an .mp3 file. To test Commanche 4, the built-in benchmark function was used, set at a screen resolution of 640x480 with 32-bit color depth.

Again the Dual Athlon MP2600+ wins by a substantial margin showing it is best for content creation.

Conclusion

Things have changed so much over the last 2-3 years that a Dual CPU system has become a compelling buy.

In virtually all computationally intensive benchmarks the Dual CPU system came out ahead and even in the gaming and multimedia benchmarks it was amongst the top scorers.

Most gamers prefer to play at 1024x768 and above and at these higher resolutions the Dual CPU machine beats all of the P4 Systems.

Unreal engine 3 (2006 release date)...

AnandTech: What kind of performance improvement (rough estimate) do you expect from a dual core CPU compared to a single core CPU with the same core? (A few percents, a bit more than 10%, tens of percents?) In other words, will a gamer "feel" the difference between a dual core and single core or between a single and dual CPU system running an Unreal 3 engine based game?

Tim Sweeney: It's too early to talk numbers, but we certainly expect Unreal Engine 3 titles to see significant gains on multi-core platforms.
