Overview
GeForce GTX 670MX is a Performance 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 Kepler GK104-N13E-GR-A2 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 24 ROPs. The Central Unit is clocked at 601MHz.

Memory
The GPU accesses a 3GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 700MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 75W, it is suited for large sized laptops.

Performance
Gaming benchmarks indicate is not too far from the desktop GeForce GTX 650 Ti.

System Suggestions
We recommend a Power Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 670MX.
