AMD Radeon HD 7750, 7770 GHz Edition hit entry level video

02/15, 12:30am

AMD unveils Radeon HD 7700 series

AMD took its Radeon HD 7000 series to the starter level quickly on Wednesday. The Radeon HD 7750 and 7750 GHz Edition step back in visual processor counts versus the 6700 line, from 720 and 800 cores to 512 and 640 respectively, but make up for it through more than a year's worth of technology. Both the new overall architecture and a shrink to a leaner 28 nanometer building process let the 7750 and 7770 climb to 800MHz and 1GHz core speeds (up from 700MHz and 850MHz).

AMD exec says DirectX getting in the way

03/19, 6:30am

Direct X API’s a barrier to performance

AMD worldwide developer relations manager of graphics Richard Huddy has blamed Microsoft’s DirectX and its APIs for limiting the potential of GPUs in PCs. 'We often have at least ten times as much horsepower as an Xbox 360 or a PS3 in a high-end graphics card, yet it's very clear that the games don't look ten times as good. To a significant extent, that's because…DirectX is getting in the way.'
