Most people don’t need 2GB of frame buffer—if they’re gamers. Palit’s GeForce GTX 460 Sonic 2GB card isn’t aimed solely at gamers, however. Like any GTX 460 card, it does a bang-up job in most modern 3D games. But at roughly $250, it’s about $20 more than the equivalent 1GB card from Palit—which also runs at a higher core clock.
Don’t think of that 2GB of RAM as just frame buffer, though. The card was designed for the emerging class of applications that take advantage of GPU compute.
The Palit Sonic 2GB offers a core clock speed of 700MHz—just 25MHz above the reference clock and 100MHz slower than the 1GB Palit Sonic Platinum card. The memory clock runs at the standard 900MHz—which is actually fairly impressive given the frame buffer size.
