Okay, so we already saw a leaked slide with some details about those AMD Barts GPUs earlier this month. A new slide posted earlier today by PCinlife reveals quite a bit more details, however—and compares key specs against today's 5700- and 5800-series Radeons.
First of all, this new document more or less confirms that Barts Pro and XT will be branded the Radeon HD 6750 and 6770. The comparison against the Radeon HD 5850 and 5870 is pretty interesting, though. From what I can see, the 6770 will have a higher fill rate, more memory bandwidth, and greater floating-point performance than the 5850. Talk about a quick mid-range card.
The 6750, meanwhile, will purportedly have the same memory bandwidth and pixel fill rate as the 5850, but with a lower texel fill rate and slower floating-point performance. No matter how you look at it, though, that card promises to be well ahead of the 5770—you know, provided this is a genuine AMD slide and not something put together by a homeless man high on cough syrup. Now all we need is some pricing information. (Thanks to TR reader Tyler for the link.)
