Radeon HD 4830 512MB Review Part1

AMD (ATI) Radeon HD 4830 Review Part1:
Introduction & Specifications

Just-another-card from AMD to cover the price point vacuum between Radeon HD 4670 & HD 4850, as well as to battle with Nvidia's Geforce 9800 GT. This card is based on the RV770LE core, which has 1 cluster of shader processors (usually defective) disabled, bringing the magic number to 640. Where the fully functional RV770 (HD4850/4870) have all the 800.

An interesting to note, AMD confirmed that disabling the cluster is a hardware-cut, so chances are it is impossible for anyone to "revive" the card with a modded BIOS. Let aside the controversy surrounding its "missing shaders", let's take a look at this extracted review:
