CHIP DESIGNER AMD has released its mainstream Radeon HD 7750 and Radeon HD 7770 graphics cards.
The AMD Radeon HD 7000 series got off to a flying start with the wider press praising the firm's 28nm Tahiti GPU chip in the Radeon HD 7970 and Radeon HD 7950. While the prices were high, the performance and overclockability were there and now the firm has tackled the price issue with the 512-core Radeon HD 7750 and the 640-core Radeon HD 7770.
For its mainstream follow-up cards AMD said there are no major cuts in features from the all-conquering Radeon 7900 series. So the Radeon HD 7700 series has DirectX 11.1 support, Eyefinity 2 and Zerocore power, plus an attempt to grab headlines by claiming that the Radeon HD 7770 is the first 1GHz+ GPU.
AMD's attempt to polish the Radeon HD 7770 with the 1GHz claim is really neither here nor there. Board vendors have been clocking their Radeon HD 7970s at 1GHz and there are countless forum posts and reviews around showing the Tahiti GPU can be overclocked well past 1.2GHz.
As for the Radeon HD 7750, the talk was about having all the next generation graphics core goodies at less than 75W. Of course at that TDP the GPU clock speed takes a dive down to 800MHz, but boards based on the Radeon HD 7750 will not require external power connectors and could have single-slot coolers.
AMD's graphics card vendors are pricing the Radeon HD 7770 cards at around the £120 to £130 mark. The Radeon HD 7750 can be had for less than £100. µ
