In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675MX Mac Edition are significantly better than the Nvidia GeForce GTX 765M.

The GeForce GTX 765M has a 131 MHz higher core clock speed than the GTX 675MX, but the GTX 675MX has 48 more Texture Mapping Units than the GeForce GTX 765M. As a result, the GTX 675MX exhibits a 26.1 GTexel/s better Texture Fill Rate than the GeForce GTX 765M. 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 131 MHz higher core clock speed than the GTX 675MX, but the GTX 675MX has 16 more Render Output Units than the GeForce GTX 765M. As a result, the GTX 675MX exhibits a 9.4 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 GTX 675MX, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 765M has 1024 MB more video memory than the GTX 675MX, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 675MX has superior memory performance.

The GTX 675MX has 95.9 GB/sec greater memory bandwidth than the GeForce GTX 765M, which means that the memory performance of the GTX 675MX is massively better than the GeForce GTX 765M.

The GeForce GTX 675MX Mac Edition has 1344 Shader Processing Units and the GeForce GTX 765M has 768. However, the actual shader performance of the GTX 675MX is 966 and the actual shader performance of the GeForce GTX 765M is 653. The GTX 675MX having 313 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 675MX delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GTX 765M.

The GeForce GTX 675MX Mac Edition requires 100 Watts to run and the GeForce GTX 765M requires 65 Watts. The GTX 675MX requires 35 Watts more than the GeForce GTX 765M to run. The difference is significant enough that the GTX 675MX may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GTX 765M.

GPU Mini Review

Mini ReviewThis is the iMac version of GeForce GTX 675MX.

It also comes with a Kepler GK104 GPU but identical to the one used on GeForce GTX 680M. In fact, the core-clock even runs at the same speed but the operating memory clock is clocked 1250MHz, increasing its bandwidth.

As a result, the card is over 15% faster than its regular version but GeForce GTX 680MX is still faster.
GeForce GTX 760M is a Performance 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 GK106-N14E-GE-B-A1 which has 4 Stream Multiprocessors activated and thus offers 768 Shader Processing Units, 64 TMUs and 16 ROPs. The Central Unit is clocked at 850MHz.

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 1002MHz.

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

Power Consumption
With a rated board TDP of 65W, it is suited for large laptops.

Despite being underclocked, when compared to GeForce GTX 650 Ti, GeForce GTX 765M ends up performing better in most cases as fast since the Kepler Boost 2.0 Technology allows an even higher Central Unit Speed, which most times exceeds the 950MHz.
Gaming benchmarks indicate its performance is on average with the desktop GeForce GTX 650 Ti.

System Suggestions
We recommend a Powerful Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 765M.
