A friend of mine today and I were discussing which mac offers the best CPU performance-per-dollar. It was started because we were discussing AppleTV as a cheapo machine for cluster setups and such. Now, let me first disclaim things: This was ONLY based on CPU score, and price of the Apple machine in stock form. The CPU data was all from SPEC.ORG, using thier CINT2000 scoring. Macs are generally not listed, so I used an equivalent machine from Dell or IBM (which shouldnt matter all that much, they all share the same intel chipset and basic architecture) The data is in "performance units per dollar" (Took the CPU score and divided it by the retail price) Is the data bulletproof? far from it. but at least its some sort of comparison. Here we go!: Apple TV - 1Ghz Pentium M - 2.29 Mac Mini Core Duo 1.66Ghz - 2.32 MacPro Quad 2.00Ghz - 2.13 MacPro Quad 2.66Ghz - 2.20 MacPro Quad 3.00Ghz - 2.04 It appears the Mini is the best performance for dollar, with AppleTV a close second. Granted, this comparison has nothing to do with useability, memory, graphics, etc etc. But for building a cheapo render farm, or a "folding farm" the mini appears pretty strong. Just figured I would share.
