The implementation of this boost mode is done in the BIOS, but it is ultimately dependent upon the manufacturer of the laptop. PCIe 3.0 is now supported by the mobile Kepler series and an optional Turbo mode can automatically overclock the Nvidia card by a theoretical 15 percent if the laptop cooling system allows it.

However, due to the missing hot clock of the shader domain, two shaders of a Kepler chip are about as fast as one shader of a Fermi chip (as the latter is clocked twice as fast).

Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are still expected to be up to twice as power efficient. The GK107 Kepler core offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores that are clocked at the same speed as the central core. The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. Due to a higher core clock of up to 850 MHz the GT 650M is noticably faster than the 640M. The graphics card uses a 128-Bit wide memory interface with either the more common but slower DDR3 for VRAM or the more expensive and faster GDDR5. It is a Kepler-based GPU built on the GK107 architecture and is manufactured in 28nm at TSMC. The NVIDIA GeForce GT 650M is a mid-range, DirectX 11.1 compatible graphics card that was announced in the first quarter of 2012 for laptops.
