The GPU wars certainly heated up in the past year or so, and they don't show any signs of cooling down. It's not just a game of playing leapfrog for the performance crown anymore, either. When all things are equal (or close to being equal), game bundles can be the nudge you need if you're on the fence. With that in mind, EVGA let us know that it's giving away copies of Ubisoft's Watch Dogs with the purchase of select GeForce GTX graphics cards.
The GTX 570 is the little brother of Nvidia’s current high-end GTX 580. Like the original GTX 480, the GTX 570 has 480 shader cores active, and 32 disabled. Since it’s based on the GTX 580 GPU, however, Nvidia’s able to run the GTX 570 at a higher clock rate than the GTX 480. On the other hand, the memory controller is 320 bits wide, versus the GTX 480’s 384-bit controller. That’s still wider than the 256-bit memory bus on the Radeon HD 6970.
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.
