AMD launches the Radeon HD 6670, 6570, 6450
Next up we have the middle card, the Radeon HD 6570 which should be the replacement for the Radeon HD 5570. Once again we're looking at an increase in stream processors, although this time the increase doesn't double the shader count, but the Radeon HD 6570 still gains 80 shaders. Here AMD has also boosted the texture unit count from 20 to 24 over the Radeon HD 5570, but the ROPs and stencil buffers remain the same. The core clock speed hasn't been increased compared to the previous generation and neither has the memory clocks. The Radeon HD 6570 is expected to arrive with an MSRP of about $79 (S$99).
Once again AMD is promising playable frame rates at 1600×900 resolution and an average performance increase over a two year old Radeon HD 4650 by 40 percent, or 30 percent over an Nvidia GeForce GT 440. AMD is also promising Eyefinity gaming at above 30fps at 4800×900 resolution (three times 1600×900) as once again we're looking at a card with support for three simultaneous displays. Of course there's 3D stereoscopic support on offer here as well and here AMD claims support of resolutions of up to 1920×1080 for games.
Once again, looking at some real benchmarks we're not seeing quite the kind of numbers AMD is claiming, at least not unless the quality settings are reduced. That said, this time around we're looking at a much better card than the Radeon HD 6450, but it's still far from a great choice for an avid gamer.
