Reviews are flowing in for AMD's latest midrange 28nm GPUs, the Radeon HD 7770 GHz Edition and HD 7750, both based on the company's Southern Islands Cape Verde architecture. The new cards are focused on lower power performance, with the HD 7770 GHz using 25W less than the HD 6850 it can be seen to replace. AMD is also touting the HD 7770 GHz as being the first card to break the 1GHz barrier, though it said the same about the Radeon HD 4890 back in May 2009.

Anandtech, Tom's Hardware, Tech Report, TechPowerUp, PC Perspective, and Guru 3D have all reviewed the cards, and have reached very similar conclusions. All agree that while the low-power performance of the HD 7770 GHz is impressive, the feature benefits over the HD 6800 series it replaces — particularly the HD 6850 — are so slim that the older card might be a better purchase. Tom's Hardware also points to Nvidia's GeForce GTX 460 1GB as offering very similar performance to AMD's new range, despite being launched more than a year and a half ago.

One common theme is the recommendation of the HD 7750 as a potential HTPC card, though Guru 3D points out that the single-slot design with active cooling makes it noisier than you might like, and recommends that you look for a passive-cooled version. In benchmarks, the HD 7750 scored a respectable 193/210 on the HQV test, backing up its home theater credentials. Both cards are on sale today, with the HD 7770 GHz costing $159 and the HD 7750 running to $109.
