GeForce GTX 660M is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler 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.
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.
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.
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
With a rated board TDP of 45W, it is suited for average sized laptops.
Gaming benchmarks indicate its performance is not too far from the desktop GeForce GTX 650.
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GTX 660M.
what is both different ? GTX 660 and GTX 660M ?? Um.. Maybe same
Im stable at 1235/3000, temps while gaming never over 78 celcius, really nice card :D
There is some wrong info on here.
Memory data rate:5000 / Speed: 2000
Mem Banwidth: 80gb
total ava graphics memory :4096
Shared memory: 2048
can i run the sim 4 ultra high setting with 1920*1080p an how fps i get?
How is this worse than the gt750m? It consistently has better GPS?
Can anyone tell me why Game Debate has the memory bandwidth at 64GB/s and the memory speed at 1000Mhz for the gtx660m? GPU-Z and Nvidia control panel says my bandwidth is 80.0GB/s and mem speed is 1250Mhz and i have never OC'ed? thx
Battlefield 4 :
Any predictions on how well bf4 will run on the 660m?
Can someone please drop a report on average FPS?
And Medium settings?
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 just got this gpu in my laptop and this is a beast
