Intel says theirs is. Apple says the G4 is faster, and on, and on, and on... AMD is faster at one thing, Intel at another, and the G4 is blazing with Adobe Photoshop (no doubt because it was written for the Mac). I recall recently putting dual Athlons against dual Intel products here at CCC, and dual AMD machines weren't even close to the dual Intel machines. Intel was around 1.9x faster on a dual for Crafty, and AMD only around 1.6x. It all depends on what you're doing and how a program takes advantage of the hardware. Ex. Macs are usually slower at running just about everything, except Photoshop and maybe a few others. It's no coincidence that on Apple's website all they talk about is how Photoshop runs 90% faster on a Mac than a P4 2.5GHz machine. It's also no coincidence that what you read about AMD being faster comes from the AMD site. They certainly aren't going to tell you about the tests anyone ran that showed the Athlon to be slower now are they? I could play 1,000 games against Fritz and come up with 8 draws somewhere along the way and then I could post my 8 draws and say that I'm as good as Kramnik. Statistics can always be manipulated. Look at all of those magical games of Eduard Nemeth that you see him post here. He doesn't bother to post the 20 games he lost horribly for each incredible win he scores. Levels of truth... 4. (lowest level) What someone else tells you 3. What you read in a book (or magazine, or website in this case) 2. What you read in the product's documentation 1. (highest level) What it does when you run it. So this website is on level 3, what Vincent tells you about what he reads in the Intel and AMD manuals is level 2, and what Robert Hyatt does when he compares WHAT THEY DO is level 1 truth. In level 1 truth tests, Intel has won by a non-trivial margin. At least that has been my experience. YMMV... Russell
