In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 740M are significantly better than the Nvidia GeForce GT 635M.
The GeForce GT 740M has a 135 MHz higher core clock speed and 8 more Texture Mapping Units than the GeForce GT 635M. This results in the GeForce GT 740M providing 9.7 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GT 740M has a 135 MHz higher core clock speed than the GeForce GT 635M and the same number of Render Output Units. This results in the GeForce GT 740M providing 2.2 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GT 740M was released over a year more recently than the GeForce GT 635M, and so the GeForce GT 740M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 635M.
The GeForce GT 740M and the GeForce GT 635M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The memory bandwidth of the GeForce GT 740M and the GeForce GT 635M are the same, which means the GeForce GT 740M and the GeForce GT 635M have equal limitations when it comes to graphical data transfer.
The GeForce GT 740M has 384 Shader Processing Units and the GeForce GT 635M has 144. However, the actual shader performance of the GeForce GT 740M is 311 and the actual shader performance of the GeForce GT 635M is 194. The GeForce GT 740M having 117 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 740M delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GT 635M.
The GeForce GT 740M transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 635M. This means that the GeForce GT 740M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 635M.
The GeForce GT 740M requires 45 Watts to run and the GeForce GT 635M requires 35 Watts. The GeForce GT 740M requires 10 Watts more than the GeForce GT 635M to run. The difference is not significant enough for the GeForce GT 740M to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 635M.

|Mini Review||Overview |
GeForce GT 740M is a Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.
It equips a GPU Codenamed GK107-GT-740M which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 810MHz.
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Kepler Boost, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 45W, it is suited for average sized laptops.
GeForce GT 740M is essentially a fast GeForce GT 640M.
Gaming benchmarks indicate its Performance is around 3% worse than the older GeForce GT 650M.
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 740M.
GeForce GT 635M is a fast-middle-class Mobile Graphics Card based on the second revision of the Fermi Architecture.
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.
It equips a GPU Codenamed GF116 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 675MHz.
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 35W, it is suited for 15" or larger laptops.
GeForce GT 635M is essentially a renamed GeForce GT 555M v3.
Gaming benchmarks put its performance identical to a GeForce GT 555M v3.
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 635M.
