MacWorld has posted the first Mac benchmarks for id Software's Doom 3.
The upcoming first person shooter has already been shipping for the PC, but will be coming to the Mac in mid-March. MacWorld was able to test the Gold Master version of Doom 3 and should represent the same performance as the shipping copy.
The testing configuration was a Power Mac G5 2.5GHz Dual processor with 2.5GB of RAM with the ATI Radeon X800 XT graphics card.
The demo really pushes the hardware, and it's not the same as what you'll go through in much of the game. There's a lot of movement, a lot of texture data and a lot of animation and complex geometry. When we ran Doom 3 itself with a frame counter, it often stayed in ranges much higher than these numbers suggest, and the game itself is throttled to 60 frames per second -- regardless of how fast the demo runs, 60 FPS is as fast as you'd ever see the actual game go.
Doom 3 will have a 1.5GHz G4 Minimum with an ATI Radeon 9600 or Nvidia GeForce FX 5200 card at a minimum.
