MacComparisonZone: G4/400 MHz Power Mac vs G4/1.25 GHz Power Mac - What Are The Performance, Feature And Price Differences

Specially prepared for Jim ... Request your own Custom Comparison

8/31/04

Introduction

This Buyer's Guide compares the G4/400 MHz Power Mac (with the DVD ROM optical drive), to the G4/1.25 GHz Power Mac (with the Combo optical drive).

The G4/400 MHz Power Mac was released in July of 2000. It was the low-end model of a family of three, which includes a 450 MHz machine in the middle, and 500 MHz machine on the high-end.

The G4/1.25 GHz Power Mac was released in June of 2003. It was released on its own, a holdover machine from the last generation, as the main Power Mac line moved on the G5 processors and a new design.

Major Technological Differences:

Notes

Note that the 1.25GHz machine's clock speed is 3.13x As Fast as the 400MHz one.

In basic processing power, the 1.25 GHz Power Mac appears to have between two and a half, and three and a half times the performance of the G4/400

Unfortunately due to the time gap between when these two machines were tested, we cannot compare hard drive performance

The Graphics card of the newer Tower turns in almost 4 times the performance of the older machine

In the General Interface test (measuring on-screen graphics), again the new machine turns in over two and a half times the G4/400 performance

Processor performance based on AltiVec Fractal program

Graphics Gaming (Card) Test is based on the game 4x4 EVO2 .. a racing game. All settings are at medium quality. This game is more graphics card dependent

The 'General Interface' test is based on Let1kWindowsBloom, which is freely available.

The Photoshop (Workflow) score is based on the BareFeats Photoshop Action Script, which you can download and run on your own machine, if you have Photoshop, or download the Trial version from Adobe
