In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670M 3GB are significantly better than the Nvidia GeForce GT 445M v2.

The GTX 670M was released over a year more recently than the GT 445M, and so the GTX 670M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 445M.

The GTX 670M has 2048 MB more video memory than the GT 445M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 670M also has superior memory performance overall.

The GTX 670M has 32 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the GTX 670M is noticeably better than the GT 445M.

The GeForce GT 445M v2 has 144 Shader Processing Units and the GeForce GTX 670M 3GB has 336. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the GTX 670M is 402. The GTX 670M having 238 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 670M delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 445M.

The GeForce GT 445M v2 requires 35 Watts to run and the GeForce GTX 670M 3GB requires 75 Watts. The GTX 670M requires 40 Watts more than the GT 445M to run. The difference is significant enough that the GTX 670M may have a slight adverse affect on your yearly electricity bills in comparison to the GT 445M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 445M v2 is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Fermi Architecture.

The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

It equips a GPU Codenamed GF106-N11E-GE-A1 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 570MHz.

The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 625MHz.

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

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Gaming benchmarks put its performance almost on level with the desktop GeForce GT 450 v4.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 445M v2.
GeForce GTX 670M 3GB is a high-end mobile GPU still based on the 2010 Fermi architecture.
It's based on the Fermi GF114 Core which offers 336 Shader Processing Units, 56 TMUs and 24 ROPs on a 192-bit memory interface of 3GB GDDR5 (which is a gimmick since this GPU does not benefit from a 2GB frame buffer, let alone 3GB). The central clock runs at 598MHz and the memory clock operates at 750MHz. Expect a power consumption of up to 75 Watts.
It's essentially a tweaked GeForce GTX 570M with a slightly higher clocked central unit that consumes the same power and so expect modern demanding games to be playable at 1080p with fluent frame rates (30+).
