AnandTech had a meeting with ATI and got a look at the background story of the Radeon HD 4800 (RV770) GPU. You can check it out over here.
Normally when a manufacturer like AMD tells me they did something, I ask why. When Intel introduced me to Nehalem’s cache architecture, I asked why and later published my findings. And for the most part, with every aspect of the Radeon HD 4800’s architecture, we did the same. Derek Wilson and I spent several hours on the phone and in emails back and forth with AMD trying to wrap our heads around the RV770’s architecture so that we could do it justice in our reviews. But both of us all but ignored the biggest part of RV770: the decision that led to making GPU itself.
This is a tough article for me to write, there are no graphs, no charts, no architecture to analyze. I simply got to sit in that room and listen as these individuals, these engineers shared with me over the course of two hours the past three years of their lives. I want to do it justice, and I hope that I can, because what they conveyed to me in that room was the best meeting I’d ever had with AMD or ATI.
