From PC World: Nvidia said Tuesday that it has hit a true milestone for portable gaming with its new GeForce GTX 980 laptop GPU—true 1:1 performance with its desktop counterpart.
That’s right, there’s no ‘m.’ The new GPU is essentially the same as putting a desktop GeForce GTX 980 into a laptop. In fact, Nvidia said, the new laptop GPU is the exact same desktop chip. It has the same 2,048 CUDA cores, the same memory bandwidth, and the same 256-bit memory bus. With the laptop GeForce GTX 980, it says, a consumer can now buy a single-GPU laptop or desktop and get the same graphics performance.
Never before has single-GPU performance ever been at parity between laptops and desktops. That meant consumers who needed to take their gaming on the go have always had to compromise. That era ends with the new GPU.
So how do you take a ginormous GPU like the desktop GeForce GTX 980 with its 165-watt thermals and power requirements and jam it into a laptop? Very carefully.
Kaustubh Sanghani, a general manager with Nvidia, said to pull off such a feat, the chips are first sorted for power requirements. Known as “binning,” chips can be sorted like diamonds for certain characteristics. Sanghani said the chips with the best power characteristics make the GeForce GTX 980 what it is.
