The Tech Report spotted a rumor that claims AMD will outfit its Radeon HD 6700 series with 256-bit memory interfaces.
The Juniper chip in existing Radeon HD 5700-series products, of course, has a 128-bit path to memory. Coupled with the high transfer rates of GDDR5 RAM, that interface width translates into a not-too-shabby 76.8GB/s of bandwidth for the 5770—but the figure pales in comparison to the Radeon HD 5870's 153.6GB/s. Memory isn't solely to blame for Juniper's relatively tame performance, though. Juniper also has about half the pixel-pushing resources of its big brother Cypress.
DonanimHaber's story doesn't seem to be all about memory, either. It says AMD wants to "raise the bar" in the mid-range market to make up for the beefier integrated graphics that will show up in next year's CPUs.
