Rene Haas, general manager of notebook products at Nvidia, predicted that the company's more efficient and powerful GeForce 600M GPUs "will be the most popular discrete GPUs used with Intel 's coming Ivy Bridge processor."
Integrating 1,536 Cores
Among other things, the new GTX680 card for desktop PCs integrates a staggering 1,536 cores running at a clock speed of just over 1GHz as well as 2GB of 256-bit GDDR5 memory . Moreover, clock speed can be slightly bumped to a higher boost frequency to maximize gaming performance.
"The most important thing to understand about GPU Boost is that it works through real-time hardware monitoring as opposed to application based profiles," wrote James Wang, GeForce.com editor-in-chief. "As an algorithm, it attempts to find what is the appropriate GPU frequency and voltage for a given moment in time."
Built using 28-nanometer process technology, Nvidia claims its GTX680 delivers twice the performance per watt of the GeForce GTX 580 while consuming 28 percent less power than rival AMD's Radeon HD7970 GPU. The GTX680 also integrates a block of new streaming SMX multiprocessors that collectively deliver twice the performance per watt of previous-generation products, Nvidia said.
Additionally, Nvidia had unleashed a new GeForce 301.10 WHQL driver designed for use with the company's GeForce GTX 680 GPU. The new driver improves upon the multisampling anti-aliasing technology for removing jagged lines, and enhancing overall fidelity in gaming applications.
"With the launch of the GeForce 301.10 driver, a high-speed, shader-based anti-aliasing technique can be enabled directly through the Nvidia control panel," Burnes wrote. "Called FXAA, this technique is up to 60 percent faster than 4xMSAA."
