In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7730M are significantly better than the Nvidia GeForce GT 630M.
The GeForce GT 630M has a 85 MHz higher core clock speed than the Radeon HD 7730M, but the Radeon HD 7730M has 16 more Texture Mapping Units than the GeForce GT 630M. As a result, the Radeon HD 7730M exhibits a 7.8 GTexel/s better Texture Fill Rate than the GeForce GT 630M. 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 630M has a 85 MHz higher core clock speed than the Radeon HD 7730M, but the Radeon HD 7730M has 12 more Render Output Units than the GeForce GT 630M. As a result, the Radeon HD 7730M exhibits a 6.6 GPixel/s better Pixel Fill Rate than the GeForce GT 630M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The Radeon HD 7730M was released less than a year after the GeForce GT 630M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The Radeon HD 7730M has 1024 MB more video memory than the GeForce GT 630M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 7730M also has superior memory performance overall.
The memory bandwidth of the Radeon HD 7730M and the GeForce GT 630M are the same, which means the Radeon HD 7730M and the GeForce GT 630M have equal limitations when it comes to graphical data transfer.
The Radeon HD 7730M has 512 Shader Processing Units and the GeForce GT 630M has 96. However, the actual shader performance of the Radeon HD 7730M is 294 and the actual shader performance of the GeForce GT 630M is 127. The Radeon HD 7730M having 167 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7730M delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GT 630M.
The Radeon HD 7730M transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 630M. This means that the Radeon HD 7730M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 630M.
The Radeon HD 7730M requires 25 Watts to run and the GeForce GT 630M requires 33 Watts. The GeForce GT 630M requires 8 Watts more than the Radeon HD 7730M to run. The difference is not significant enough for the GeForce GT 630M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7730M.

|Mini Review||Overview |
Radeon HD 7750M is a Fast-Middle-Class Mobile Graphics Card based on the First revision of the GCN Architecture.
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.
It equips a GPU codenamed Chelsea LE which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit Initially Operates at 575MHz and goes up to 675MHz, in Turbo Mode.
The GPU accesses a 1GB frame buffer of fast DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.
With a rated board TDP of 32W, it is suited for 15" or larger laptops.
Gaming benchmarks put its on average with NVIDIA's GeForce GT 640M.
We recommend a Modest Processor (Intel Core i3 Mobile) and 4GB of RAM for a system with Radeon HD 7730M.
GeForce GT 630M is a Middle-Class Mobile Graphics Card based on the first revision of the Fermi 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.
It equips a GPU Codenamed GF108 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 660MHz.
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 33W, it is suited for small laptops.
GeForce GT 630M is essentially a GeForce GT 540M.
Gaming benchmarks indicate its performance is on average with the older GeForce GT 540M.
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 630M.
