One hundred and ninety-five Earth pounds for the finest graphics chip AMD currently produces? A GPU with no less than 1,600 stream shaders, support for DirectX 11, a triangle-mashing hardware tessellator and much, much more? That's got to be some deal, right? Yes and no. The Radeon HD 5830 chipset is indeed based on AMD's mighty Cypress chip. But in this guise it's been given a thorough pruning. First for the chop is that forest of 1,600 stream shaders, trimmed back to 1,120. The texture unit count also tumbles from 80 for the full-on 5870 chipset to just 56, while 16 of Cypress's 32 render outputs have also been hacked off.
