ATI's Radeon 4870 X2 Review
Posted on 2008-08-12 14:28:05 by Thomas De MaesschalckAs with the 3870X2 and Nvidia's other dual GPU options the ATI Radeon 4870 X2 is two 4870s and as with the 3870 X2 are featured on the same PCB. This makes for a whopping 1600 stream processors but ATI have also gone further and bumped up the memory to 1GB GDDR5 per card standard bringing the total to 2GB of GDDR5 memory onboard which should easily handle resolutions of 1920x1200 and above with 8x anti-aliasing. As you'll see in our tests this extra RAM comes in handy and beats out two 4870s in Crossfire at the highest settings and resolutions. The 4870 X2 also does a better job communicating between the two GPUs with much more bandwidth available and unlike the 3870X2 uses a PCIe 2.0 switch. When those moments kick in where the card really needs the extra bandwidth this will certainly come in handy. The card is long and features a massive heatsink as you'd expect on a card like this but isn't larger than Nvidia's latest cards and is actually the same length as a regular 4870.
