* GeForce GT 730M Overview
GeForce GT 730M is a 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 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 725MHz.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

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

Power Consumption
With a rated board TDP of 33W, it is suited for small laptops.

Performance
GeForce GT 730M is essentially a fast GeForce GT 645M.
Gaming benchmarks indicate its performance stands somewhere between GeForce GT 645M & GeForce GT 650M.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 730M.

* GeForce GTX 560M  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.

Nvidia GeForce GTX 560M are significantly better than the Nvidia GeForce GT 730M

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560M are significantly better than the Nvidia GeForce GT 730M.

The GeForce GTX 560M has a 50 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GT 730M. This results in the GeForce GTX 560M providing 1.6 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 560M has a 50 MHz higher core clock speed and 8 more Render Output Units than the GeForce GT 730M. This results in the GeForce GTX 560M providing 7 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 730M was released over a year more recently than the GeForce GTX 560M, and so the GeForce GT 730M is likely to have better driver support, meaning it will be more optimized for running the latest games.

The GeForce GT 730M has 512 MB more video memory than the GeForce GTX 560M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GTX 560M has superior memory performance.

The GeForce GTX 560M has 31.2 GB/sec greater memory bandwidth than the GeForce GT 730M, which means that the memory performance of the GeForce GTX 560M is noticeably better than the GeForce GT 730M.

The GeForce GT 730M has 384 Shader Processing Units and the GeForce GTX 560M has 192. However, the actual shader performance of the GeForce GT 730M is 278 and the actual shader performance of the GeForce GTX 560M is 298. The GeForce GTX 560M having 20 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 560M delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GT 730M.

The GeForce GT 730M transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 560M. This means that the GeForce GT 730M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 560M.

The GeForce GT 730M requires 33 Watts to run and the GeForce GTX 560M requires 75 Watts. The GeForce GTX 560M requires 42 Watts more than the GeForce GT 730M to run. The difference is significant enough that the GeForce GTX 560M may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GT 730M.

Reasons to consider the MSI GeForce GTX 560 Ti

Higher memory bandwidth	134.4 GB/s	vs	40 GB/s	More than 3.2x higher memory bandwidth
