* 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.

Nvidia GeForce GT 730M are very slightly better than the Nvidia GeForce GT 640M

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 730M are very slightly better than the Nvidia GeForce GT 640M.

The GeForce GT 730M has a 100 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GT 640M. This results in the GeForce GT 730M providing 3.2 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 GT 730M has a 100 MHz higher core clock speed than the GeForce GT 640M and the same number of Render Output Units. This results in the GeForce GT 730M providing 1.6 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 less than a year after the GeForce GT 640M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 730M and the GeForce GT 640M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The memory bandwidth of the GeForce GT 730M and the GeForce GT 640M are the same, which means the GeForce GT 730M and the GeForce GT 640M have equal limitations when it comes to graphical data transfer.

Both the GeForce GT 730M and the GeForce GT 640M have 384 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the GeForce GT 730M has 3.2 GTexel/s better Texture Fill Rate and 1.6 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the GeForce GT 730M takes the edge.

The GeForce GT 730M requires 33 Watts to run and the GeForce GT 640M requires 32 Watts. The GeForce GT 730M requires 1 Watts more than the GeForce GT 640M to run. The difference is not significant enough for the GeForce GT 730M to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 640M.

 

But, Nvidia GeForce GT 650M are better than Nvidia GeForce GT 730M.
