This past Tuesday we did an article on the Diamond Viper Radeon HD 3870 1GB video card and it turns out some of the details in that article were incorrect. When the Diamond Multimedia launched the first 1GB ATI Radeon HD 3870 graphics card they had the memory interface incorrectly labeled as 512-bit. Legit Reviews contacted the Diamond Multimedia marketing department and they confirmed it was really just 256-bit.
