In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660M are massively better than the Nvidia Quadro FX 770M.

The GeForce GTX 660M was released over three years more recently than the Quadro FX 770M, 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 Quadro FX 770M when running the latest games.

The GeForce GTX 660M has 1536 MB more video memory than the Quadro FX 770M, 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 38.4 GB/sec greater memory bandwidth than the Quadro FX 770M, which means that the memory performance of the GeForce GTX 660M is noticeably better than the Quadro FX 770M.

The Quadro FX 770M has 32 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the Quadro FX 770M is 16 and the actual shader performance of the GeForce GTX 660M is 365. The GeForce GTX 660M having 349 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 Quadro FX 770M.

The Quadro FX 770M requires 35 Watts to run and the GeForce GTX 660M requires 50 Watts. The GeForce GTX 660M requires 15 Watts more than the Quadro FX 770M 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 Quadro FX 770M.

GPU Mini Review

Mini ReviewQuadro FX 770M is a professional GPU for mobile workstations optimized for professional applications and openGL features.
Its gaming performance is beyond a GeForce GT 230M but it has no gaming driver support and so it's not recommended for gaming purposes.
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.
