Power Color 9800 Platinum Edition - Manipulated Radeon 9800 Pro
After doing a little digging, we quickly discovered that the 9800 Platinum Edition is nothing more than a Radeon 9800 Pro GPU which is cut-down a little to help reduce the retail price for consumers. The 9800 Platinum Edition only uses a 128-bit memory bus compared to the 256-bit on the "true" 9800 Pro and the memory speed is a little slower on the Platinum Edition by around 40MHz (80MHz DDR) which gives the "true" 9800 Pro the ability to push about 2GB more bandwidth per second.
