In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 are significantly better than the Nvidia GeForce GTX 850M 2GB.
The GeForce GTX 660 has a 44 MHz higher core clock speed and 40 more Texture Mapping Units than the GTX 850M. This results in the GeForce GTX 660 providing 41 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 660 has a 44 MHz higher core clock speed and 8 more Render Output Units than the GTX 850M. This results in the GeForce GTX 660 providing 8.5 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 GTX 850M was released over a year more recently than the GeForce GTX 660, and so the GTX 850M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 660.
The GeForce GTX 850M 2GB and the GeForce GTX 660 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The GeForce GTX 660 has 112.2 GB/sec greater memory bandwidth than the GTX 850M, which means that the memory performance of the GeForce GTX 660 is massively better than the GTX 850M.
The GeForce GTX 850M 2GB has 640 Shader Processing Units and the GeForce GTX 660 has 960. However, the actual shader performance of the GTX 850M is 937 and the actual shader performance of the GeForce GTX 660 is 992. The GeForce GTX 660 having 55 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 850M.
The GeForce GTX 850M 2GB requires 45 Watts to run and the GeForce GTX 660 requires 140 Watts. We would recommend a PSU with at least 450 Watts for the GeForce GTX 660, but we do not have a recommended PSU wattage for the GTX 850M. The GeForce GTX 660 requires 95 Watts more than the GTX 850M to run. The difference is significant enough that the GeForce GTX 660 may have an adverse affect on your yearly electricity bills in comparison to the GTX 850M.

| Mini Review | PLEASE NOTE THAT THIS GRAPHICS CARD HAS 2 VARIANTS: DDR3 AND GDDR5. THIS IS THE DDR3 VARIANT. GeForce GTX 850M 2GB is a fast-middle-class mobile graphics card. It is based on 28nm GM107 Core of the Maxwell architecture. The Maxwell architecture features many improvements and amongst them is the extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient. GeForce GTX 850M 2GB DDR3 comes with a full variant of the GM107 Core and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit of standard DDR3. While the central unit runs at 936MHz and goes up to 1084MHz, in Turbo Mode, the memory clock operates at 1000MHz. It has a rated TDP board of around 45W. The DDR3 variant is better suited for 720p but it comes higher clocked. Thus it proves to be way faster than GeForce GTX 750M and surpasses slightly the higher positioned GeForce GTX 760M. In fact, it should be pretty close to the desktop GeForce GTX 750. This card should be paired with a Very Strong Dual Core Processor or a Decent Quad Core and at least 8GB of RAM. | Overview GeForce GTX 660 is a Performance Graphics Card based on 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 GK106-400-A1 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 24 ROPs. The Central Unit is initially clocked at 980MHz and goes up to 1033MHz, in Turbo Mode. Memory The GPU accesses a 2GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz. Power Consumption With a rated board TDP of 140W, it requires at least a 450W PSU with one available 6-pin connector. Performance GeForce GTX 660 competes with Radeon HD 7850. At 1920x1080, the best suited resolution for GeForce GTX 660, benchmarks indicate its performance is a little over the older GeForce GTX 570 and quite superior to Radeon HD 7850. System Suggestions GeForce GTX 660 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance. | |||
