      The Redwood is manufactured on TSMC’s 40nm process and has 627 million transistors on a die that is 104mm2 in size. The 40nm process is used on all ATI Evergreen family chips and the HD 5670 has 400 Stream Processors, 20 Texturing units, and 8 ROPs (Outputted Pixels). In many respects, the HD 5670 is ½ of a HD 5770 or Juniper core with ½ of the SPs, ROPs, and TMUs.

      One spot where the HD 5670 is not ½ of a HD 5770 is in the clock speed. The HD 5670 from XFX has a clock speed of 775MHz, which is slower than that of the HD 5770 and faster than the HD 5750. Another spot where the card is more than ½ is the memory bandwidth. The HD 5670 has a 128-bit memory bus just like the HD 5770. With a memory clock of 1GHz or 4GHz effective with GDDR5 memory, the memory bandwidth on the card is 64GB/second.

      DirectX 11 is the latest graphics API from Microsoft which is the predominant graphics API on the market today with OpenGL a distant second in terms of the gaming uses. DirectX 11 brings three main things to the graphics cards: Tessellation, DirectCompute, and Multi-threading support. I’ll cover each of these features here. DirectCompute supports General-purpose computing on the graphics chip in Windows Vista and 7.

      Eyefinity is ATI’s multi-display utility that they have installed on all Evergreen family members including the HD 5670. The HD 5670 has a DVI-I connectors, an HDMI connector, and a DisplayPort connector. Eyefinity allows this card to run three displays simultaneously with the third display needing the DisplayPort to run. This solution is elegant compared to the NVIDIA version which requires two cards as you can drive three monitors on the least expensive card.
