Andrey Vorobiev; November 16, 2010.

On the example of AMD Radeon HD 5670 512MB DDR5 (775/775/4000 MHz).

Price: Newegg, Amazon.


  • GPU: Radeon HD 5670 (Redwood)
  • Memory: 512MB GDDR5 SDRAM in 4 chips on the front side of the PCB
  • Interface: PCIe x16
  • GPU clock rate (ROPs/Shaders): 775/775 MHz (standard)
  • Memory clock rate, physical (effective): 1000 (4000) MHz (standard)
  • Bus: 128-bit
  • Stream processors: 400
  • TMUs: 20
  • ROPs: 12
  • Size: 190x100x16 mm
  • PCB color: black
  • RAMDACs/TDMS: integrated into GPU
  • Outputs: DVI (Dual-Link/HDMI), Display Port, HDMI
  • Multi-GPU mode: software CrossFireX

This card features its own audio codec, so nothing else is required to output audio to HDMI.

This card can work with three monitors simultaneously.

Maximum resolutions and frequencies:

  • 240 Hz maximum refresh rate
  • 2560 x 1600 @ 60Hz Max via digital interface (all Dual-Link DVIs)

MPEG2 playback (DVD-Video) was analyzed back in 2002 and little has changed since that time. Modern graphics cards do not load CPUs during video playback by more than 25%.
