As I stated in this other thread http://www.steinberg.net/forum/viewtopic.php?f=81&t=859&p=8204#p8204, I recently found the top-of-the-line HP i7 box on sale for $1680 and snaped it up.
It has a 6-core i7 980x @ 3.33GHz
I installed a completely clean copy of Win7 Ultimate, hooked it up with my existing ProFire 2626, and ran some tests with and without hyperthreading. Got almost identical results using the DAW Bench Cubendo native test with the Cubase x64 multiband compressor:
i7 980x 6x 3.33GHz
64 samples latency: 152 Mband compressors
128 samples latency: 179 Mband compressors
256 samples latency: 207 Mband compressors
This is a little less than 3x the performance of my old Q6600 (a $600 PC two years ago). Based on the info I had been reading about how amazing the i7 was relative to my Q6600, I was a little underwhelmed. So I started looking around for optimizations that still applied to Win7 and found this
This covers probably most of the optimizations I’ve seen floating around the web. I tried some right out of the gate–turning off all of the nonessenial background services on boot, disabling my realtime antivirus protection (temporarily!), turning off all visual effects so it looks like Win NT, setting the PC for performance over visuals, and optimizing for background servies not UI. None of these really did anything to increase the number of multiband compressors I could enable before hearing the occasional glitch. I’m starting to think OSes and processors are advanced enough that these optimizations aren’t really doing much anymore… as my tests show. Is there something I’m missing that I should be doing?
