In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 470M are very slightly better than the Nvidia GeForce GTX 660M.

The GeForce GTX 660M has a 300 MHz higher core clock speed but 16 fewer Texture Mapping Units than the GeForce GTX 470M. The lower TMU count doesn't matter, though, as altogether the GeForce GTX 660M manages to provide 1 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 GTX 660M has a 300 MHz higher core clock speed but 8 fewer Render Output Units than the GeForce GTX 470M. The lower ROP count doesn't matter, though, as altogether the GeForce GTX 660M manages to provide 0.6 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 GTX 660M was released over a year more recently than the GeForce GTX 470M, and so the GeForce GTX 660M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 470M.

The GeForce GTX 660M has 512 MB more video memory than the GeForce GTX 470M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 660M also has superior memory performance overall.

The GeForce GTX 660M has 4 GB/sec greater memory bandwidth than the GeForce GTX 470M, which means that the memory performance of the GeForce GTX 660M is marginally better than the GeForce GTX 470M.

The GeForce GTX 660M has 384 Shader Processing Units and the GeForce GTX 470M has 288. However, the actual shader performance of the GeForce GTX 660M is 365 and the actual shader performance of the GeForce GTX 470M is 308. The GeForce GTX 660M having 57 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 660M delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GTX 470M.

The GeForce GTX 660M transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 470M. This means that the GeForce GTX 660M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 470M.

The GeForce GTX 660M requires 50 Watts to run and the GeForce GTX 470M requires 75 Watts. The GeForce GTX 470M requires 25 Watts more than the GeForce GTX 660M to run. The difference is not significant enough for the GeForce GTX 470M to have a noticeably larger impact on your yearly electricity bills than the GeForce GTX 660M.

GPU Mini Review

Mini ReviewOverview
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.
Overview
GeForce GTX 470M is a High-End Mobile Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture was first 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.

GPU
It equips a GPU Codenamed GF104-N11E-GT which has 6 Stream Multiprocessors activated and thus offers 288 Shader Processing Units, 48 TMUs and 24 ROPs. The Central Unit is clocked at 550MHz.

Memory
The GPU accesses a 1.5GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 625MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 75W, it is only suited for large laptops.

Performance
Gaming benchmarks put its performance identical to a desktop GeForce GTS 450.

System Suggestions
We recommend a fast processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 470M.
