ATI Mobility Radeon HD 4870 X2

Two mobility radeon hd 4870 in crossfire style (similar to sli). doubles the efficacy consumption but shows plainly 0-50% better operation (depends upon the game succor ,  drivers and settings).

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. plane demanding directx 10 games of 2008 (crysis warhead ,  far squall 2) may be played with elevated details.

The mobility hd 4870 x2 is based upon two rv770 chips and features 2x800 flow processors (2x160 5-dimensional shader cores). these cores execute the graphic drudgery of the shader- and pixel pipelines of older gpus. the flow processors are also called alus and are grouped in five-way vliw units. 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 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). this uvd 2 supports full bitstream decoding of h.264/mpeg-4 avc and vc-1 streams. in addition to this ,  it also supports dual video flow decoding and picture-in picture style which makes the uvd full bd-live compliant. simplified ,  the avivo hd applied Science handles all video tasks and enables the gpu to decode hd videos.


Amd published a current consumtion of about 2x65 watt for the hd 4870 x2. 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).

The card supports as the original mobile card gddr 5 graphic reminiscence. the implore is ,  if this expeditious reminiscence may be utilised by the card optimally (because of the slow core clock compared to the desktop counterpart). furthermore ,  the pricing is rather elevated ,  hence most cards volition feature frequent gddr 3 ram.

Compared to the desktop ati radeon hd 4870 x2 ,  the mobile 4870 x2 features a slower core clock and therfore should execute a scintilla slower than a desktop hd 4850 x2.

the czech website pctuning.cz own already published an immense inquiry of the  asus w90 with a intel c2d t9600 and 6 gb ram. the following gaming benchmarks stem from their inquiry.
