I just found this video - an eee running supercollider and jack! http://www.mcld.co.uk/blog/blog.php?171 Also I found this benchmark: http://novosche.blogspot.com/2007/12/eee-pc-benchmark-test-asus-eee-pc-4g.html It's notated kind of inscrutably but I think it can be translated thusly. Each cell shows average percentage of CPU to run the given number of supercollider ugens / synth voices on the given platform. So lower is better. 128 ugens/ | 256 ugens/ | 384 ugens/ | 448 ugens/ 32 synths | 64 synths | 96 synths | 112 synths HARDWARE | | | ----------------------+------------+-------------+-------------- powerbook 22.2% | 43.5% | 64% | 81% G3 333Mhz | | | ----------------------+------------+-------------+-------------- powerbook 8% | 15% | 20% | 23% G4 1.67GHz | | | ----------------------+------------+-------------+-------------- EEE PC | | | 4G model 8% | 14% | 19.6% | 22.2% ----------------------+------------+-------------+-------------- macbook | | | pro intel 3.2% | 6.1% | 9% | 10.5% 1.84 GHz | | | ----------------------+------------+-------------+-------------- What this appears to show is that the EEE is roughly equivalent to a powerbook G4 1.67 GHz, for this particular benchmark. And almost half the speed of an intel macbook pro 1.84. That's not bad considering the G4 *still* costs more on ebay than the EEE does new. There's also a test of the number of synth voices at which the EEE and the macbook pro each reach 66% CPU. If I read it right, the MBP can do 800 voices (3200 ugens). The EEE can do 356 (1424 ugens). -- Paul Winkler http://www.slinkp.com _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
