Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 765M are marginally better than the Nvidia GeForce GTX 670MX.
The GeForce GTX 765M has a 197 MHz higher core clock speed but 16 fewer Texture Mapping Units than the GeForce GTX 670MX. The lower TMU count doesn't matter, though, as altogether the GeForce GTX 765M manages to provide 3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GTX 765M has a 197 MHz higher core clock speed than the GeForce GTX 670MX, but the GeForce GTX 670MX has 8 more Render Output Units than the GeForce GTX 765M. As a result, the GeForce GTX 670MX exhibits a 1.6 GPixel/s better Pixel Fill Rate than the GeForce GTX 765M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GTX 765M was released less than a year after the GeForce GTX 670MX, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GTX 765M and the GeForce GTX 670MX have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The GeForce GTX 670MX has 3.1 GB/sec greater memory bandwidth than the GeForce GTX 765M, which means that the memory performance of the GeForce GTX 670MX is marginally better than the GeForce GTX 765M.
The GeForce GTX 765M has 768 Shader Processing Units and the GeForce GTX 670MX has 960. However, the actual shader performance of the GeForce GTX 765M is 663 and the actual shader performance of the GeForce GTX 670MX is 576. The GeForce GTX 765M having 87 better shader performance is not particularly notable, as altogether the GeForce GTX 670MX performs better when taking into account other relevant data.
The GeForce GTX 765M requires 75 Watts to run and the GeForce GTX 670MX requires 75 Watts. We would recommend a PSU with at least 120 Watts for the GeForce GTX 670MX, but we do not have a recommended PSU wattage for the GeForce GTX 765M. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

| Mini Review | GeForce GTX 770M is a high-end mobile graphics card based on the 28nm, Kepler architecture.
It's based on the Kepler GK106 Core and offers an identical core configuration to the desktop, GeForce GTX 650 Ti. Therefore, it offers 768 Shader Processing Units, 64 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5.
While the central unit runs at 850MHz and goes up to XXXMHz, in Turbo Mode, the memory clock operates at 1000MHz. Its power consumption is around 75W and thus only suited for average to large notebooks.
Its at heart just a higher-clocked GeForce GTX 760M.
Paired with a strong Quad Core, all demanding games will run at the highest settings, using a 1680x1050 resolution. | | | | GeForce GTX 670MX is a high-end GPU based on the 28nm, Kepler architecture.
It's based on the Kepler GK106 Core and offers 960 Shader Processing Units, 80 TMUs and 24 ROPs on a 192-bit memory interface of fast GDDR5. The central unit runs at 600MHz and the memory clock operates at up to 700MHz.
Despite its huge 3D Mark 11 score, its gaming performance is still quite inferior to the Fermi based GeForce GTX 675M and only about 10% better than GeForce GTX 670M.
Its performance should, however, be slightly better than GeForce GTX 675M in DirectX 11 based games and much worse at 1080p resolutions due to the limited memory bandwidth. |
