This is no scientific test!! Probably not relevant to anyone - so don't read on! Just a small comparison for my own sake to see if my old PC will perform better or just more reliable than my MBP bootcamp.
The old pc: 1 GHz AMD Athlon, 768 MB Ram, XP PRO SP3
First of all I've checked the DPC latency to see if there's any obvious differences between the machines.
I notice that my PC running for 10 minutes have a very steady latency about 170 mySec and the absolute maximum is 334 mySec!!
This is quite interesting compared to the MBP spikes mentioned ealier in my blog. Just sweet green colums stroling by on the old PC - and that's not even a clean install!
At first my little testrun seems fine - doing mono input 44,1/24 for a couple of minutes. I get greedy and change the project samplerate to 96kHz and try to playback. Then the program freezes and after a while the pc reboots automatically... wierd! Has never seen that before.
Next time I startup Sequoia I try to make a new VIP project in 96kHz but everything just freezes and I have to reset the pc.
Recording in 96/24 with my old Delta 66 PCI with buffer 256 samples ASIO buffer made:
- 2 "record errors" with 1 stereo track
- 4 "record errors" with 1 stereo tracks
- 6 "record errors" with 1 stereo tracks
- 8 "record errors" with 1 stereo tracks
Also when playing back the info bar yields "2 lost ASIO buffer" each time I stop playback.
I also tried recording with Fireface in 96/24 in another DAW and interestingly the pc froze and restarted like when I started out in Sequoia.
(after a little more testing jumping to the conclusion:)
Generally it seem, that I can record and playback a lot of 44/24 tracks on my old pc but as soon as I make the shift to 88,2 or 96 kHz I get in trouble and have bad response from the system.
It hasn't got a lot of horsepower but I stable when it only has to deal with projects within its league.
