AMD is planning to round off its Radeon HD 6000 series with the release of HD 6750 and HD 6770. These cards are already available for OEMs and offer nothing new – they are simply rebrands of the 18 month old HD 5700 cards – with the addition of HD3D and HDMI 1.4a. The immense gap between highest end Turks (6670) and lowest end Barts (6790) had left a hole in the HD 6000 line-up which AMD can only fill in with the rebrand.
The availability of the HD 6670 remains questionable, as does its price. HD 5750s are tending to the $100 mark and the HD 5770s are available in the $120 range. The HD 6790 is somewhat overpriced as well, at $150, considering HD 6850s can be had for as low as $165. Simply put, AMD will need to drop prices of the HD 6790 and HD 6670, to accomodate the "new" HD 6700 at slightly lower prices than its HD 5700 predecessors.
AMD has been in a hurry to complete the Radeon HD 6000 – with no less than 6 cards across 4 series releasing in April. The rumour mill is pushing hard for a Radeon HD 7000 series as early as Q3. Let's hope a true successor to the HD 5700 series is just around the corner.
