ATI Radeon HD 6870 and HD 6850 reviewed, deemed worthy of the midrange
AMD's Radeon HD 6870 and HD 6850 graphics cards are here, but they might not be what you expect -- though alphanumerics suggest they'd succeed the lauded Radeon HD 5870 and 5850, these new "Bart" chips are actually a pair of solid plays for the PC gaming mainstream. $180 buys you a Radeon HD 6850 with 960 stream processors, a 775MHz core clock and 1GB of GDDR5 memory at a 1GHz effective rate, and $240 nets the HD 6870 with 1120 stream processors and 900MHz / 1,050 MHz clocks respectively. On paper that puts them a good bit behind the finest, but a collection of reviews show they can keep up with the pack, as the 6870 consistently manages to surpass the framerates possible with NVIDIA's $200 GeForce GTX 460, and even the cheaper 6850 can do the same in certain games. Some reports indicate they run a good bit hotter than their predecessors, however, so despite the bevy of ports they're probably not right for your next HTPC. Hit up the reviews below for some promising benchmarks, and if you aren't turned away by AMD's lipsticking of the pig, you'll find ten varieties already for sale at our source link. PR after the break. Update: NVIDIA's GeForce GTX 460 768MB now sells for $170, so there's definitely still some mid-range muscle in the green camp.

AMD Radeon HD 6770 and 6750 spec sheets emerge, give NVIDIA cause for concern
Alright AMD, we still haven't forgiven you for burying the glorious name that was ATI, but if your next GPU refresh is as mighty as these numbers indicate, we might at least let you in from the doghouse. A slide detailing two flavors of the upcoming 40nm Barts chip has sprouted up from two independent sources online, and it shows some appreciable gains between generations. The new HD 67x0 cards appear manifestly speedier than their predecessors -- with faster clocks, more texture units, and more ROPs -- but the fun really gets going when you compare them to the HD 5870 and 5850, AMD's previous high-end cards. Memory bandwidth and pixel fillrate are identical between the HD 6750 and 5850, while the HD 6770 even manages to beat the formerly imperious 5870 in a couple of areas. Of course, this is all still unconfirmed information, but considering that Barts is only an "upper midrange" chip that's already stepping on the toes of last year's finest, we feel safe in expecting some pretty big things from the flagship Cayman silicon when it lands -- which will be soon if all these leaks and rumors are anything to go by.
