As you probably already know, the Radeon HD 4870 X2 employs two RV770 GPUs, each of which is complemented by 1GB of GDDR5 memory (for a total of 2GB frame buffer memory). The reference GPU clock speed for the 4870 X2 is 750 MHz, and the reference memory speed is 900 MHz. Diamond, however, boosted the XOC's clocks to 800 MHz and 950 MHz, respectively, making this one of the fastest 4870 X2 cards on the market. Click the link below and check it out...
Diamond Radeon HD 4870 X2 XOC Review
Marco Chiappetta
Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
