IMG Reviews CPU Upgrades from Giga Designs, Sonnet
12:25 PM | Lucian Fong | Comment on this story

As long as Apple's Power Macs had been stuck at 500 megahertz, the CPU upgrade market was stagnant for even longer. Back in late 1999, Motorola hit a brick wall with the PowerPC 7410 processor (aka G4), which interrupted the product cycles of Apple and CPU upgrade companies. Finally, three CPU upgrade companies hit the 1 gigahertz plateau: Giga Designs, Sonnet, and PowerLogix. Today, IMG takes an in-depth look at CPU upgrades from Giga Designs and Sonnet. Here is an excerpt from the article:

I was very surprised at the performance of the G-celerator 800. Even with a 50% increase in raw megahertz, it was not able to outperform the stock CPU in these benchmarks. When compared directly to the Encore/ST G4 800, you can see the effect that a large L3 cache can have in games. On the other end of the spectrum, the two 1 GHz upgrades offer practically identical performance.
If you're in the market for a processor upgrade, or if you just want to look at the nifty charts and graphs, read the rest of the article.
