motionless it is unclear if this worth represents the chip alone or the whole mxm board including the reminiscence (which would include about 2x5 watt). simplified, the avivo hd applied Science handles all video tasks and enables the gpu to decode hd videos.Īmd published a current consumtion of about 2圆5 watt for the hd 4870 x2. in addition to this, it also supports dual video flow decoding and picture-in picture style which makes the uvd full bd-live compliant. this uvd 2 supports full bitstream decoding of h.264/mpeg-4 avc and vc-1 streams. The mobility radeon hd 4870 x2 includes the avivo hd called video applied Science including an onboard soundchip for 7.1 sound output over hdmi or displayport and the 2nd generation uvd (unified video decoder). each of the five directions of a vliw bundle has to be independent from the others and hence the operation depends upon the optimization of the driver.

the flow processors are also called alus and are grouped in five-way vliw units.

these cores execute the graphic drudgery of the shader- and pixel pipelines of older gpus. The mobility hd 4870 x2 is based upon two rv770 chips and features 2x800 flow processors (2x160 5-dimensional shader cores). plane demanding directx 10 games of 2008 (crysis warhead, far squall 2) may be played with elevated details. Because of the elevated amount of shaders (2x800) the gaming operation is very good and allows the gaming of all directx 9 games in elevated resolutions and details.
