Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7730M are significantly better than the Nvidia GeForce GT 630M 2GB DDR3.
The 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 GT 630M. As a result, the Radeon HD 7730M exhibits a 7.8 GTexel/s better Texture Fill Rate than the 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 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 GT 630M. As a result, the Radeon HD 7730M exhibits a 6.6 GPixel/s better Pixel Fill Rate than the 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 GT 630M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 630M 2GB DDR3 and the Radeon HD 7730M 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 630M 2GB DDR3 and the Radeon HD 7730M are the same, which means the GT 630M and the Radeon HD 7730M have equal limitations when it comes to graphical data transfer.
The GeForce GT 630M 2GB DDR3 has 96 Shader Processing Units and the Radeon HD 7730M has 512. However, the actual shader performance of the GT 630M is 192 and the actual shader performance of the Radeon HD 7730M is 460.8. The Radeon HD 7730M having 268.8 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 GT 630M.
The GeForce GT 630M 2GB DDR3 requires 33 Watts to run and the Radeon HD 7730M requires 25 Watts. The GT 630M requires 8 Watts more than the Radeon HD 7730M to run. The difference is not significant enough for the GT 630M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7730M.

|Mini Review||GeForce GT 630M 2GB DDR3 is a variant of the middle-class GeForce GT 630M. |
Based on the Fermi GF108, it offers 96 Shader Processing Units, 16 TMUs and 4 ROPs on a 128-bit interface of DDR3.
The central unit runs at 660MHz and will go up to 800MHz in Turbo Mode while the memory clock operates at 900MHz. A 1GB version which will offer the same performance, since this GPU does not benefit from a 2GB frame buffer and most likely cost less, is also available.
Its overall performance is clearly superior to previous GeForce GT 620M/625M and also above previous GeForce GT 540M and slightly above GeForce GT 550M and so most modern demanding games can be played at medium settings smoothly using a 1366x768 (most common) resolution while modern games are playable using the high preset smoothly.
|Radeon HD 7730M, codenamed 'Chelsea LP', is a fast-middle-class GPU part of the Mobility HD 7000M Series released by AMD in 2012. |
It's based on the new GCN (Graphics Core Next) architecture and therefore not related to any of the previous AMD GPUs. The core-clock will range from 575MHz to 675MHz, and will be decided by the laptop manufacturer, probably according to the cooling system.
Very Demanding games, like Metro 2033, The Witcher II and Max Payne 3, should run smoothly at medium settings, while less demanding games, such as Crysis 2 and Skyrim V, might be playable with high settings and attractive resolutions.
