GeForce GTX 660M Review

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.

It is better than the GT750M but slightly behind the GT755m. It can be OCed and it will outperform the 755m.

im not sure about the bandwidth but 1250Mhz is normal mem speed for the 660m.

I'd say medium-high with 1366x768 resolution, if you are running 1080p probably a solid medium.

I don't think we will get a solid medium at 1080p.
It is a pretty big jump from BF3.

I believe it will be possible. With a 15 percent overclock on this card you can play bf 3 in ultra so ya i think a medium is possible.

Texture filtering and mesh quality on Ultra, reso 900p will give me FPS 90+ on every map.

Use MSI Afterburner and clock your core clock to 970MHz, that is 14% performance boost. I use 660m and i get 60 fps at 1080p with Ultra Texture and Mesh quality, no AA and everything else medium. Ambience should be turned off.

Can strongly recomend this card! It runs Battlefield smoothly with high, almost ultra graphic settings and a full resolution of 1920x1080 when playing campaign.
Online i can play with medium/high graphics whitout any problem.
Good value for money! :)

I'm not sure about my twin brother's. He has a 3720QM, he has a GTX660M in a package, and he is changing out his Radeon HD6990M. Will it run well?
