Yes I did post about the performance loss with the dual core AMD 3800, but works well with the dual core box. It's Reason, FL Studio, and Orion Platinum that suffered and I assumed that it must be because none of them are able to make full use of the dual core processor and other reasons which I'll explain here.DevonB wrote:Weren't you the one who was having problems with performance with the off-the-shelf HP box though?

About Cubase SX. I noticed that steinberg advertises only SX 3.1 as being capable of handling dual core. My question is how much is it really an improvement over let's say an equivalent single core cpu?
And how does older versions (sx2 for example) handle dual core?

It doesn't seem to make sense, but there's something that I can point out that might shed some light on this situation. If you right click on "My Computer" and get properties, you can see the speed at which your processor is running. I have 3 machines close by. The Athlon 3200 single processor machine reads 1.99Ghz (All the time and doesn't change regardless of what I'm doing) which I believe is the actual speed of the processor. The iMac reads 2.0Ghz which is exactly the speed of the Intel Core Duo processor, again, all the time and doesn't fluctuate regardless of processor load. The Amd 3800 X2 box reads 994Mhz at the moment. What's also interesting is that this number fluctuates depending on what I'm doing on the machine. Yesterday it read 887Mhz or something close. When I tested it in the past, I got all kinds of different numbers as I loaded the processor with more tasks. I've also read that with these dual core boxes, the processor speed doesn't run at the full speed of the equivalent single processor because of heat problems. I'm not an expert in any of this, but I read this on the net somewhere. The Intel Core Duo is different in that it is the first chip built with this new 65 nanometor process that allows it to achieve better performance with less power consumption and less heat of course. Again, I'm no expert, but this does seem to sort of corroborate my story of loss of performance compared to my AMD 3200 box which has a single processor that's exactly one of the cores of the dual core box. So the way I'm seeing this is, if the single core of a dual core processor is running at 994Mhz instead of the full 2.0Ghz, and the program is only able to use a single core, then the performance of that application would understandably suffer greatly which is what I saw with Reason, FL and Orion.
