In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro K3100M are noticeably better than the Nvidia GeForce GTX 660M.

The GeForce GTX 660M has a 129 MHz higher core clock speed than the Quadro K3100M, but the Quadro K3100M has 32 more Texture Mapping Units than the GeForce GTX 660M. As a result, the Quadro K3100M exhibits a 18.5 GTexel/s better Texture Fill Rate than the GeForce GTX 660M. 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 129 MHz higher core clock speed than the Quadro K3100M, but the Quadro K3100M has 16 more Render Output Units than the GeForce GTX 660M. As a result, the Quadro K3100M exhibits a 9.2 GPixel/s better Pixel Fill Rate than the GeForce GTX 660M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Quadro K3100M was released over a year more recently than the GeForce GTX 660M, and so the Quadro K3100M 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 Quadro K3100M has 2048 MB more video memory than the GeForce GTX 660M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Quadro K3100M also has superior memory performance overall.

The Quadro K3100M has 38.4 GB/sec greater memory bandwidth than the GeForce GTX 660M, which means that the memory performance of the Quadro K3100M is noticeably better than the GeForce GTX 660M.

The Quadro K3100M has 768 Shader Processing Units and the GeForce GTX 660M has 384. However, the actual shader performance of the Quadro K3100M is 542 and the actual shader performance of the GeForce GTX 660M is 365. The Quadro K3100M having 177 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro K3100M delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce GTX 660M.

The Quadro K3100M requires 75 Watts to run and the GeForce GTX 660M requires 50 Watts. The Quadro K3100M requires 25 Watts more than the GeForce GTX 660M to run. The difference is not significant enough for the Quadro K3100M to have a noticeably larger impact on your yearly electricity bills than the GeForce GTX 660M.

GPU Mini Review

Mini ReviewQuadro K3100M is a high-end business card based on the 28nm, Kepler architecture.
Technically the successor to the previous Quadro 3000M, it's based on the Kepler GK104 (despite the SPU count) and offers 768 Shader Processing Units, 64 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 706MHz and the memory clock operates at up to 800MHz.
Quadro K3000M's drivers are certified for professional applications only. Its gaming performance is comparable to GeForce GTX 760M.
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.
