Depending on the GPU Boost 2.0 up to 30 % better performance can be achieved (according to Nvidia). The graphics performance of the GeForce GTX 760M is clearly above the GTX 660M thanks to the higher amount of shaders. 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 of similar speed to one shader of a Fermi chip (as the latter is clocked twice as fast). Although the Kepler architecture can utilize more shader cores than a Fermi chip, its shaders can be up to twice as power efficient. ![]() In the GTX 760M, four blocks are active for a total of 768 CUDA cores. The GK106 Kepler core offers five shader blocks, called SMX, 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. Depending on the cooling headroom of the laptop and the application / game, up to 15 % performance gains are possible. However, the memory bus is still only 128 Bit wide.Īs a novelty, the GeForce 700M series implements GPU Boost 2.0 to automatically overclock the core clock rate. In contrast to the GTX 660M, the 760M now uses the GK106 chip and offers twice the amount of shaders at a slightly reduced core speed. The NVIDIA GeForce GTX 760M is a upper mid-range DirectX 11-compatible graphics card for laptops. NVIDIA GeForce GTX 760M ► remove from comparison
