GeForce GTX 680MX is a High-End 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 Kepler Kepler GK104-N13E-GTX-A2 which has 8 Stream Multiprocessors activated and thus offers 1536 Shader Processing Units, 128 TMUs and 32 ROPs. The Central Unit is clocked at 719MHz.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1250MHz.
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
With a rated board TDP of 122W, it is suited for very large sized laptops.
Gaming benchmarks indicate is not too far from the desktop GeForce GTX 660 Ti.
We recommend a Power Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 680MX.
i have this on my msi gt70 0ne ! superb graphics card ! perfect for nfsmw 2 and crysis 3 !! very impressive :) thanx nvidia xD
This is not a laptop GPU. While it is listed as a mobile gpu is not and only avaiable in all-in-one mac's. The highest in a laptop is a 680m which is a underclocked gtx 670. The 680mx is a underclocked 680. SO yes you over clock these like i have and you can achieve a higher core clock than the stock desktop versions but not a higher memory clock.
And they say you can't game on a Mac
only better 1% than my GPu?lol
Does it fit in my laptop?
266% better than my gpu, well that's embarrassing :D
o ho hoo…..122W for laptop ??=Đ
Allright, and if NVIDIA GeForce GTX 685MX 2GB GDDR5 releases, it would be awesome!
NVIDIA GeForce GTX 680 2GB GDDR5 is only 22% faster than NVIDIA GeForce GTX 680MX 2GB GDDR5… I'm going to jizz right now!
