Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7670M are noticeably better than the Nvidia GeForce GT 540M.
The GeForce GT 540M has a 72 MHz higher core clock speed than the Radeon HD 7670M, but the Radeon HD 7670M has 8 more Texture Mapping Units than the GeForce GT 540M. As a result, the Radeon HD 7670M exhibits a 3.6 GTexel/s better Texture Fill Rate than the GeForce GT 540M. 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 540M has a 72 MHz higher core clock speed than the Radeon HD 7670M, but the Radeon HD 7670M has 12 more Render Output Units than the GeForce GT 540M. As a result, the Radeon HD 7670M exhibits a 6.9 GPixel/s better Pixel Fill Rate than the GeForce GT 540M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The Radeon HD 7670M was released over a year more recently than the GeForce GT 540M, and so the Radeon HD 7670M is likely to have better driver support, meaning it will be more optimized for running the latest games.
The Radeon HD 7670M and the GeForce GT 540M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The Radeon HD 7670M has 28.8 GB/sec greater memory bandwidth than the GeForce GT 540M, which means that the memory performance of the Radeon HD 7670M is slightly better than the GeForce GT 540M.
The Radeon HD 7670M has 480 Shader Processing Units and the GeForce GT 540M has 96. However, the actual shader performance of the Radeon HD 7670M is 158 and the actual shader performance of the GeForce GT 540M is 129. The Radeon HD 7670M having 29 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7670M delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GT 540M.
The GeForce GT 540M requires 35 Watts to run but there is no entry for the Radeon HD 7670M.

|Mini Review||Radeon HD 7670M is an upper middle-class level GPU part of the 7000M Series released by AMD. |
It's technically the successor of the middle-class Radeon HD 6650M. However, due to the fast GDDR5 memory type, the performance should be clearly better so Very Demanding games like Metro 2033 might be playable at medium settings (depending on the resolution + DirectX Version used) while demanding games like Crysis 2 are probably playable at high settings. Old and less demanding games like COD: Black Ops should be playable at max settings easily.
|GeForce GT 540M is a middle-class mobile GPU still based on the 2010 Fermi architecture. |
It's based on the Fermi GF108 Core and offers 96 Shader Processing Units, 16 TMUs and 4 ROPs on a 128-bit memory interface of 1GB DDR3. The central clock runs at 672MHz and the memory clock operates at 900MHz. Expect a power consumption of up to 35 Watts.
GeForce GT 540M is essentially a higher clocked GeForce GT 525M and so expect to only be able to play most modern demanding games at medium settings but with very fluent frame rates (40+) using a 720p resolution.
