In this business we all need to know how to say I don't know and you taught me something as things change too fast to have our feet in concrete. Lionel is right ... I say it all the time. Maybe I don't know, but fortunately the members of this list are more than willing to share their knowledge

Other way around. Modern processors are in instructions per clock. On raw CPU power it doesn't just beat the mainframe - it steamrollers them. Your I/O bus is typically PCI however so you are limited to about 100Mbytes/second I/O throughput in the real world. I would regard 100Mb/sec as a

Lets take a real world benchmark. On $2000 of PC I can recompile the entire Linux kernel in 3 minutes, and the entirity of XFree86 in 30. I can saturate multiple 100Mbit links with web traffic. I can encode video in real time to mpeg and burn it to VideoCD as I go. I can render 1024x768 3D

Vendor provided comparisons between its own products. Comparisons by Ford between Ford cards don't tell you anything about whether its a Porsche or Bicycle equivalent. And *no* credible mainstream computing journalist will trust a vendor provided benchmark. They've seen enough such material,
