In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660M are massively better than the Nvidia GeForce 705M 1GB.

The GeForce GTX 660M has a 60 MHz higher core clock speed and 24 more Texture Mapping Units than the GeForce 705M 1GB. This results in the GeForce GTX 660M providing 20.5 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 60 MHz higher core clock speed and 12 more Render Output Units than the GeForce 705M 1GB. This results in the GeForce GTX 660M providing 10.3 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 705M 1GB was released over a year more recently than the GeForce GTX 660M, and so the GeForce 705M 1GB 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 660M has 1024 MB more video memory than the GeForce 705M 1GB, 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 49.6 GB/sec greater memory bandwidth than the GeForce 705M 1GB, which means that the memory performance of the GeForce GTX 660M is noticeably better than the GeForce 705M 1GB.

The GeForce 705M 1GB has 48 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the GeForce 705M 1GB is 74 and the actual shader performance of the GeForce GTX 660M is 365. The GeForce GTX 660M having 291 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 660M delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce 705M 1GB.

The GeForce GTX 660M transistor size technology is 12 nm (nanometers) smaller than the GeForce 705M 1GB. This means that the GeForce GTX 660M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 705M 1GB.

The GeForce 705M 1GB requires 15 Watts to run and the GeForce GTX 660M requires 50 Watts. The GeForce GTX 660M requires 35 Watts more than the GeForce 705M 1GB to run. The difference is significant enough that the GeForce GTX 660M may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce 705M 1GB.

GPU Mini Review

Mini ReviewOverview
GeForce 705M is a entry-level Mobile Graphics Card based on the second revision of the Fermi Architecture.

Architecture
GeForce 705M equips a GPU Codenamed GF119-B1 which is a Second Generation Fermi GPU.
Still built on 40nm Technology, it has 1 Stream Multiprocessor activated and thus offers 48 Shader Processing Units, 8 TMUs and 4 ROPs.

GPU
The Speed of the Central Unit Varies from Laptop to Laptop. Usually, it is clocked at up to 775MHz.

Memory: Speed
The GPU is equipped with DDR3 and Accesses the Frame Buffer through a 64-bit Memory Interface. The Memory Clock Operates at 900MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 1GB.

Power Consumption
With a rated board TDP of 15W, it is suited for small laptops.

Performance
GeForce 705M is essentially a renamed GeForce 610M.
Therefore, AMD's and Intel's Recent Powerful Integrated Graphics are still more powerful.

System Suggestions
GeForce 705M is best suited for resolutions up to and including 1366x768. We recommend a Middle-Class Processor and 4GB 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.
