RV790 Could Hold Higher Core Clock Speeds
Conceived to be a successor to the RV770 graphics processor, the RV790 emerged out of various media-leaks as the next big thing for ATI, in its never-ending pursuit for market leadership. Information on this mysterious new GPU has been trickling in at leisure, and it has been shaping up to be a current-generation GPU built using newer manufacturing technologies that could make it cheaper to produce. What we do know about RV790XT based engineering samples so far, is that they carry faster memory chips that are rated to operate a higher frequencies, 1 GHz to be precise, but specified by AMD to run at 975 MHz.
Fresh details sourced by Hardware-Infos from internal sources point out to the possibility of AMD stepping up the core clock speeds by as much as 100 MHz, taking it to 850 MHz. The ramp in clock speeds however, come at the expense of increasing core voltage to 1.3 Volts. There have been several reports speculating the core voltage so far, on of which points at 1.23V for 750 MHz. Another grey-area for now is the RV790's shader domain, with a certain level of ambiguity surrounding stream processor count. All of this leads us to believe that AMD hasn't finalized the specifications of RV790 and could be racking its brains on this one. AMD is expected to make critical announcements on its new GPUs in March and might choose the CeBIT event as the ideal platform.
