In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660M are massively better than the Nvidia GeForce Go 7950 GTX.

The GeForce GTX 660M was released over three years more recently than the Go 7950, and so the GeForce GTX 660M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Go 7950 when running the latest games.

The GeForce GTX 660M has 1536 MB more video memory than the Go 7950, 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 19.2 GB/sec greater memory bandwidth than the Go 7950, which means that the memory performance of the GeForce GTX 660M is slightly better than the Go 7950.

The GeForce GTX 660M has 384 Shader Processing Units but the Go 7950 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce GTX 660M requires 50 Watts to run and the GeForce Go 7950 GTX requires 45 Watts. The GeForce GTX 660M requires 5 Watts more than the Go 7950 to run. The difference is not significant enough for the GeForce GTX 660M to have a noticeably larger impact on your yearly electricity bills than the Go 7950.

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.
GeForce Go 7950 GTX is a high-end-class level GPU.
It can use up to 512MB of dedicated video memory, and it's only available with a DDR3 memory type + a 256 bits Memory Bus Width.
Due to its features and unlike the previous GeForce Go models, it should be able to play today's games, that use DirectX 9 (e.g. Sims 3, Anno 1404 and even Crysis) at the low or medium settings.
