Various Brands Radeon HD 4870 X2 Roundup

SAPPHIRE Technology – the leading innovator of ATI-based graphics solutions
for the PC – is now introducing the HD 4870 X2 – a new DUAL GPU graphics
accelerator based on the successful HD 4870 and delivering the highest levels of
graphics and gaming performance ever.

The SAPPHIRE HD 4870 X2 comprises two complete HD 4870 graphics systems on a
single PCI-Express card connected by an on-board PCI Express Gen 2 bridge chip.
Each GPU has 1MB of GDDR5 memory, making a total of 2GB on-board memory. Two
Dual Link DVI outputs are provided as well as TV-Out. 3D applications such as
games use both on-board GPU’s together in CrossFire mode to deliver a single
accelerated output on the Primary display only. In this mode, the new SAPPHIRE
HD 4870 X2 delivers performance as good or better than two HD 4870 cards in
CrossFire mode, making it the fastest performing single card available.

The SAPPHIRE HD 4870 X2 is implemented on a single ATX format PCI-Express card,
with a fan assisted cooler making it a standard dual-slot configuration. This
solution will have immediate appeal to performance users with only a single
PCI-Express slot available. On a suitable PCI Express Gen 2.0 CrossFireX
mainboard it is also possible to use two SAPPHIRE HD 4870 X2 cards in CrossFireX
mode to provide even higher levels of performance.

The SAPPHIRE HD 4870 X2 incorporates the latest ATI Avivo™ HD Technology for
enhanced Video display and features a second generation built in UVD (Unified
Video decoder) for the hardware accelerated decoding of Blu-ray™ and HD DVD
content for both VC-1 and H.264 codecs, as well as mpeg files, reducing CPU
loading to a minimum. The SAPPHIRE HD 4870 X2 is HDCP ready and is compatible
with the latest High Definition displays. Like other HD 4800 series products it
also supports HDMI over the DVI interface with the correct HDMI Adapter.

All SAPPHIRE’s current graphics cards are Microsoft Windows Vista™ certified and
supported by the ATI Catalyst™ suite of software, ensuring customers have easy
and ongoing access to software updates for performance, stability and added
