Introduction

Last year AMD released their new Radeon HD 5800 Series of graphics cards which quickly became a big success due to the numerous improvements made over previous generations. Over the course of the last months AMD has completed their DirectX 11 lineup quickly, the Radeon HD 5670 was unveiled on Jan 14. It is based on AMD's Redwood graphics processor which is made in a 40 nm process at TSMC Taiwan.
HD 5670 cards can be found around a $100 price point, which is a tough market that is crowded with other cards like the GeForce GT 240, 9600 GT and 9800 GT. AMD's own products here are HD 4770, HD 4830 and HD 4850.

AXLE, who is one of the few companies to make both NVIDIA and ATI cards, has designed a HD 5670 that uses a custom PCB design and own cooling solution. One major product highlight is certainly the 1 GB of GDDR5 memory, which is twice that of the reference design which comes only with 512 MB. Another interesting aspect is the cooler, which uses a fan by Arctic Cooling who provide low-noise, high-performance coolers.
