Introduction Because of the goodwill of some friendly people, I was able to test various CPU upgrades during the past 3 weeks. The actual testing only took a few hours of course, but I had to wait for the test units, and also for the Blue & White G3 someone lended me for testing. As a matter of fact, I'm not entirely sure how I should best present you the results. After thinking about several possibilities, I decided to go for the following, breaking things up into these parts: Review of the XLR8 MAChSpeed G4z 500MHz MPe Review of the Met@box Joecard G4 450/466MHz Review of the Sonnet Encore G3 500MHz Review of the Sonnet Encore G4 500MHz Testing machines Tests conducted Comparative charts and tables of all units, including overclocks (2 pages) Final verdicts Before you proceed, please note: All these tests were conducted to show how the CPU upgrades compare on each test system, that doesn't mean that you'll get the same results on another machine. Benchmarks are only theoretical performance indicators and do often enough not represent the real-life performance of a given machine. Now you may carry on to the testing conditions: page2: Review: XLR8 MAChSpeed G4z 500 MPe>>>
