Re: [LAU] Pre-configured Linux Audio laptop for US$499 gets some ink

Recently I measured the CPU load and battery run time of some low-delay audio DSP on an Asus Eee PC 701 (Intel Celeron M, 630 MHz), and on an Acer Aspire one (Intel Atom 1.6 GHz). The time spent in the CPU was pretty much the same for both systems, and the battery runtime was between 3 and 3 1/2 hours on the Asus (Celeron) and 2 1/2 hours on the Acer (Atom). Here is the data: algo1 Asus: 56.4% CPU, 3h14' battery Acer: 51.0% CPU, 2h28' battery P4: 20.5% CPU algo2 Asus: 49.8% CPU, 3h16' battery Acer: 47.5% CPU, 2h09' battery P4: 16.5% CPU algo3 Asus: 36.5% CPU, 3h22' battery Acer: 35.0% CPU, 2h27' battery P4: 13.0% CPU jackd Asus: 6.0% CPU Acer: 4.8% CPU P4: 2.2% CPU Sound card IRQ handler Asus: 4.5% CPU Acer: 4.2% CPU P4: 1.0% CPU (network interface with netjack) P4 is Intel Pentium 4 @ 3 GHz. I know this is no perfect benchmarking, but gives an idea of the processor performance.
