The GT 750M has a 151 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GTX 560M. This results in the GT 750M providing 4.8 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 GT 750M has a 151 MHz higher core clock speed than the GeForce GTX 560M, but the GeForce GTX 560M has 8 more Render Output Units than the GT 750M. As a result, the GeForce GTX 560M exhibits a 3.8 GPixel/s better Pixel Fill Rate than the GT 750M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards. The GT 750M was released over a year more recently than the GeForce GTX 560M, and so the GT 750M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 560M. The GeForce GT 750M Mac Edition has 384 Shader Processing Units and the GeForce GTX 560M has 192. However, the actual shader performance of the GT 750M is 356 and the actual shader performance of the GeForce GTX 560M is 298. The GT 750M having 58 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 750M delivers a slightly smoother and more efficient experience when processing graphical data than the GeForce GTX 560M.
The GT 750M transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 560M. This means that the GT 750M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 560M. While they exhibit similar graphical performance, the GT 750M should consume less power than the GeForce GTX 560M.
GPU Mini Review Mini Review Overview GeForce GT 750M Mac Edition is a Mac only, Fast-Middle-Class 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 GK107-N14P-GT which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs.
The Central Unit is clocked at 926MHz. Memory 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 1253MHz. Features 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 50W, it is suited for average sized laptops.
Performance Gaming benchmarks indicate its performance is on average with the older GeForce GTX 660M. System Suggestions We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 750M Mac Edition. Overview GeForce GTX 560M is a Performance Mobile Graphics Card based on the second revision of the Fermi Architecture. 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. GPU It equips a GPU Codenamed GF116 which has 4 Stream Multiprocessors activated and thus offers 192 Shader Processing Units, 32 TMUs and 24 ROPs.
The Central Unit is clocked at 775MHz. Memory The GPU accesses a 1.5GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 625MHz. Features DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies Power Consumption With a rated board TDP of 75W, it is suited for large laptops.
Performance Gaming benchmarks put its performance identical to a desktop GeForce GTs 450. System Suggestions We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GTX 560M. Recommended CPU Possible GPU Upgrades N/A N/A GPU Variants.
