In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 are noticeably better than the Nvidia GeForce GTX 860M 2GB.

The GTX 860M has a 49 MHz higher core clock speed than the GeForce GTX 660, but the GeForce GTX 660 has 40 more Texture Mapping Units than the GTX 860M. As a result, the GeForce GTX 660 exhibits a 37.2 GTexel/s better Texture Fill Rate than the GTX 860M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 860M has a 49 MHz higher core clock speed than the GeForce GTX 660, but the GeForce GTX 660 has 8 more Render Output Units than the GTX 860M. As a result, the GeForce GTX 660 exhibits a 7 GPixel/s better Pixel Fill Rate than the GTX 860M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 860M was released over a year more recently than the GeForce GTX 660, and so the GTX 860M 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 860M 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 64 GB/sec greater memory bandwidth than the GTX 860M, which means that the memory performance of the GeForce GTX 660 is much better than the GTX 860M.

The GeForce GTX 860M 2GB has 640 Shader Processing Units and the GeForce GTX 660 has 960. However, the actual shader performance of the GTX 860M is 948 and the actual shader performance of the GeForce GTX 660 is 992. The GeForce GTX 660 having 44 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 860M.

The GeForce GTX 860M 2GB requires 60 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 860M. The GeForce GTX 660 requires 80 Watts more than the GTX 860M 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 860M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 860M 2GB is a Performance Mobile Graphics Card based on the First Generation of the Maxwell Architecture.

Architecture
GeForce GTX 860M 2GB Features a GPU Codenamed GM107-N15P-GX-A1 which is a First Gen Maxwell GPU and is Identical to the GM107-400-A2 GPU used on the Desktop GeForce GTX 750 Ti.
It has 6 Stream Multiprocessors activated and offers 640 Shader Processing Units, 40 TMUs and 16 ROPs.

GPU
The central unit runs at 1029MHz and goes up to 1097MHz, in Turbo Mode.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1253MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB.

Power Consumption
GeForce GTX 860M 2GB Consumes between 60W and 75W depending on the Scenario.

Performance
Benchmarks Indicate Similar Performance to the older GeForce GTX 770M, using the best suited Resolution - 1600x900.
As a Result, GeForce GTX 860M provides a decent experience at 900p, in most Modern Demanding Games.

System Suggestions
GeForce GTX 860M 2GB is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
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.
