In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 965M 2GB are massively better than the Nvidia GeForce GTX 660M.

The GTX 965M has a 89 MHz higher core clock speed and 32 more Texture Mapping Units than the GeForce GTX 660M. This results in the GTX 965M providing 32.4 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 GTX 965M has a 89 MHz higher core clock speed and 16 more Render Output Units than the GeForce GTX 660M. This results in the GTX 965M providing 16.2 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 GTX 965M was released over a year more recently than the GeForce GTX 660M, and so the GTX 965M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 660M.

The GeForce GTX 965M 2GB and the GeForce GTX 660M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 965M has 16 GB/sec greater memory bandwidth than the GeForce GTX 660M, which means that the memory performance of the GTX 965M is slightly better than the GeForce GTX 660M.

The GeForce GTX 965M 2GB has 1024 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the GTX 965M is 1017 and the actual shader performance of the GeForce GTX 660M is 365. The GTX 965M having 652 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 965M delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTX 660M.

The GeForce GTX 965M 2GB requires 70 Watts to run and the GeForce GTX 660M requires 50 Watts. The GTX 965M requires 20 Watts more than the GeForce GTX 660M to run. The difference is not significant enough for the GTX 965M to have a noticeably larger impact on your yearly electricity bills than the GeForce GTX 660M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 965M 2GB is a Performance Mobile Graphics Card based on the second revision of the Maxwell architecture.

Architecture
GeForce GTX 965M 2GB Equips the GPU Codenamed GM204-N16E-GS which is a Second Gen Maxwell GPU and has 8 SM activated. It offers 1024 Shader Processing Units, 64 TMUs and 32 ROPs.

GPU
The central unit runs at 924MHz and goes up to 950MHz, in Turbo Mode.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1253MHz.

Memory: Frame Buffer
The Frame Buffer was doubled to 2GB. This is adequate for 1080p Gaming in most Games.

Power Consumption
GeForce GTX 965M 2GB has a Rated Board TDP of 50W.

Performance
GeForce GTX 965M 2GB proves to be incredible fast at resolutions up to 1920x1080. In fact, even at 1920x1080 it matches the older GeForce GTX 870M.
Above 1920x1080, GeForce GTX 965M 2GB's performance decreases significantly and becomes further distant from the higher positioned GeForce GTX 970M.
Nevertheless, all modern games should run comfortably at 1080p. It can be said its performance lies somewhere between a desktop GeForce GTX 660 and a Radeon R9 270 which are both powerful Graphics Cards.

System Suggestions
We Recommend a High-End Processor and 8GB of RAM for Optimal Performance.
Overview
GeForce GTX 660M is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

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.

GPU
It equips a GPU Codenamed GK107-N13E-GE-A2 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is initially clocked at 835MHz and goes up to 950MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, 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 1000MHz.

Features
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

Power Consumption
With a rated board TDP of 45W, it is suited for average sized laptops.

Performance
Gaming benchmarks indicate its performance is not too far from the desktop GeForce GTX 650.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GTX 660M.
