In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 650M are significantly better than the Nvidia GeForce GT 720M.
The GeForce GT 650M has a 225 MHz higher core clock speed and 16 more Texture Mapping Units than the GeForce GT 720M. This results in the GeForce GT 650M providing 17.2 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 650M has a 225 MHz higher core clock speed and 8 more Render Output Units than the GeForce GT 720M. This results in the GeForce GT 650M providing 8.6 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 720M was released over a year more recently than the GeForce GT 650M, and so the GeForce GT 720M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 650M.
The GeForce GT 720M and the GeForce GT 650M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The GeForce GT 650M has 14.4 GB/sec greater memory bandwidth than the GeForce GT 720M, which means that the memory performance of the GeForce GT 650M is slightly better than the GeForce GT 720M.
The GeForce GT 720M has 96 Shader Processing Units and the GeForce GT 650M has 384. However, the actual shader performance of the GeForce GT 720M is 180 and the actual shader performance of the GeForce GT 650M is 326. The GeForce GT 650M having 146 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 650M delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GT 720M.
The GeForce GT 720M requires 33 Watts to run and the GeForce GT 650M requires 45 Watts. The GeForce GT 650M requires 12 Watts more than the GeForce GT 720M to run. The difference is not significant enough for the GeForce GT 650M to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 720M.

|Mini Review||Overview |
GeForce GT 720M is a entry-level 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 GF117-N14M-GE which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is initially clocked at 625MHz and may reach up to 938MHz, in Turbo Mode.
Additionally, GF117 is built using a 28nm technology.
The GPU accesses a 1GB frame buffer of DDR3, through a 64-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 Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 33W, it is suited for average sized laptops.
GeForce GT 720M is essentially a fast GeForce GT 620M with the option for the Boost Clock which depends on the laptop's cooler.
Gaming benchmarks indicate its performance is slightly below the older GeForce GT 635M.
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 720M.
GeForce GT 650M is a Fast-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 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 850MHz.
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for 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.
Gaming benchmarks indicate its performance stands somewhere between GeForce GT 645M & GeForce GT 650M v2.
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 650M.
