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 720M.

The GeForce GT 720M has a 363 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 720M. As a result, the Radeon HD 7730M exhibits a 3.4 GTexel/s better Texture Fill Rate than the GeForce GT 720M. 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 720M has a 363 MHz higher core clock speed than the Radeon HD 7730M, but the Radeon HD 7730M has 8 more Render Output Units than the GeForce GT 720M. As a result, the Radeon HD 7730M exhibits a 1.7 GPixel/s better Pixel Fill Rate than the GeForce GT 720M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 720M was released less than a year after the Radeon HD 7730M, 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 720M, 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 GeForce GT 720M and the Radeon HD 7730M are the same, which means the GeForce GT 720M and the Radeon HD 7730M have equal limitations when it comes to graphical data transfer.

The GeForce GT 720M has 96 Shader Processing Units and the Radeon HD 7730M has 512. However, the actual shader performance of the GeForce GT 720M is 192 and the actual shader performance of the Radeon HD 7730M is 332.8. The Radeon HD 7730M having 140.8 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 GeForce GT 720M.

The Radeon HD 7730M requires 25 Watts to run but there is no entry for the GeForce GT 720M.

GPU Mini Review

Mini ReviewGeForce GT 720M is an entry-level GFX still based on the Fermi architecture.
It's based on the Fermi GF117 Core, which is manufactured with a 28nm technology, does comes optimized for lower power consumption and is expect to produce less heat and offers 96 Shader Processing Units, 16 TMUs and 8 ROPs, on a 64-bit memory interface of DDR3. The central unit runs at 938MHz and the memory clock operates at 900MHz.
Its performance lies, therefore, somewhere between GeForce GT 625M and GeForce GT 630M. In smaller resolutions, it should perform considerably better but the 64-bit bus width will become a bottleneck for superior resolutions (720p+).
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.
