Sapphire has announced two new models to the HD 7700 series of graphics cards which will deliver an even more affordable choice of graphics cards based off the Graphics Core Next architecture from AMD. Both models are HD 7730’s built on AMD’s 28nm process, but one model will feature 2GB of GDDR5 memory and the other model will feature only 1GB.
It looks like AMD is prepping a new lower-end graphics cards in their Radeon 7000 series. User Toppc from Coolaler forums has leaked images and well as benchmarks of a Radeon HD 7730 from MSI. Not much is known about the specifications of the card just yet, but we do know the card is clocked at 800 MHz core and 1125 MHz memory clock. We would assume it is also running 1 GB of GDDR5 memory. No official word on what core this card is running, our guess is a cut down version of either the Bonaire XT chip or Cape Verde chip.
