AMD has yet to officially launch its ATI Radeon HD 4730, but PowerColor isn't waiting around and has officially announced its own version of the forthcoming card.

PowerColor's derivative, the PCS HD 4730, pictured, sports an Arctic Cooling heatsink and fan, along with dual DVI outputs.

According to PowerColor, the card will land in stores on June 8th with a tantalising price tag of just $79.99 - not a bad number at all, considering that the card looks to be just a slower-clocked version of the impressive Radeon HD 4770.

The card's core will be clocked at 700MHz - down 50MHz from the Radeon HD 4770 - but its 512MB of GDDR5 memory will run quicker. PowerColor tells us to expect an effective memory speed of 3,600MHz - that's up 400MHz from the Radeon HD 4770's 3,200MHz - and the number of stream processors remains unchanged at 640.

If PowerColor's early numbers are right - and we've no reason to believe otherwise - the Radeon HD 4730 looks a solid mid-range solution and could bring an end to the older Radeon HD 4830 if its $80 US price tag is reflected by a sub-£70 asking price in the UK.
