Which benchmarks relate to audio applications and harddisk recording?

[Ohsoflow]

Hi,

For the PC DAW I am going to build, I am trying to decide between Asus P4PE (Intel 845PE chipset, PC2700 DDRAM) and Asus P4G8X (Intel E7205, dual channel PC2100) or Asus P4SDX (SiS655, dual channel PC2700) mobo's.

In a lot of benchmarks the E7205 scores only slightly higher than the 845PE. The problem is that I don't know if that says anything about their performances in audio applications and harddisk recording. http://www.audioforums.com/forums/frown.gif

Can anybody tell me which of the benchmarks, used by Tom's Hardware and the like, do tell something about the performance of chipsets and motherboards in that area?

Especially concerning harddisk recording, which involves the (continuous) streaming of large ammounts of data to the HD('s). Does SiSoft Sandra give information about that?

I would also like to know which benchmarks could say something about the performance of programs like Reason and Cubase, and the performance of soft synths.

Thanx-a-lot!

Jipsa

Pay particular attention to FPU floating point calculation scores. Memory access scores are also important.

thanx mr D!
with memory acces scores I suppose you mean SiSoft Sandra type of scores (memory bandwith)?
but what are FPU floating point calculation scores?

strange thing is that according to AnandTech (http://www.anandtech.com/mb/showdoc.html?i=1748&p=18)Asus P4G8X performance rivals that of an i850E, RDRAM board...

but when OCWorkBench (http://www.ocworkbench.com/2002/asus/p4g8x/p4g8xp3.htm) tested the same board, only the memory bandwith rivaled i850E; the rest was only slightly higher than i845PE...

FPU (Floating point unit) scores are really the crux of the bisquit, as almost all audio software and plugins these days use floating point math as opposed to integer calculations. The place you'll see the biggest difference is in the number of plugins your system can support, but anything that you ask your DAW to do that takes time, like track bounces, batch processing, etc., will benefit from a higher FPU score.

thanx Robert!

seems that SiSoft Sandra benchmarks also say something about the floating point. i read this at Tom's hardware: Integer MMX/floating point SSE, SSE2, 3DNow!

Is this what you were talking about?
