XFX 4870 X2
XFX package their 4870 X2 in a large box which gives away little information on the card specifications, other than memory amount which is listed twice. Inside the card is well protected and comes bundled with all of the cables and connectors we feel are standard in today’s market. This includes a CrossFire connector and DVI to HDMI dongle.
The XFX version of the 4870 X2 looks quite similar to the reference model due to the same dual slot cooler being used but the card has been subjected to a slight makeover with the use of black PCB and DVIs. Mixed with the stylish XFX artwork it makes for an impressive looking product.
As expected there are two R700 GPUs under the cooler, linked by a PCI-Express bus. These 55nm chips contain 16 ROPs and 800 Unified Shaders. Each GPU has access to 1024Mb of GDDR5 via a 256bit memory bus and XFX have chose clocks of 750MHz core, 900MHz memory.
Support for all of the standard Radeon features is present and includes PCI-Express 2.0, DirectX 10.1 and AvivoHD for acceleration of Blu-Ray content. AvivoHD is especially useful when we take into account that this card is capable of outputting high definition video over HDMI along with 7.1 audio.
