In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7670M are marginally 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 memory bandwidth of the Radeon HD 7670M and the GeForce GT 540M are the same, which means the Radeon HD 7670M and the GeForce GT 540M have equal limitations when it comes to graphical data transfer.

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 144 and the actual shader performance of the GeForce GT 540M is 129. The Radeon HD 7670M having 15 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7670M delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GT 540M.

The Radeon HD 7670M requires 20 Watts to run and the GeForce GT 540M requires 35 Watts. The GeForce GT 540M requires 15 Watts more than the Radeon HD 7670M to run. The difference is not significant enough for the GeForce GT 540M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7670M.

GPU Mini Review

Mini ReviewOverview
Radeon HD 7670M is a Middle-Class Mobile Graphics Card based on the second revision of the Terascale Architecture.

Architecture
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

GPU
It equips a GPU codenamed Thames XT which has 6 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit runs at 600MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The memory clock operates at 900MHz. The size of the frame buffer is adequate.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

Power Consumption
With a rated board TDP of 20W, it is suited for average sized laptops.

Performance
Gaming benchmarks put its performance somewhere between GeForce GT 540M and GeForce GT 550M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7670M.
Overview
GeForce GT 540M is a middle-class Mobile Graphics Card based on the first revision of the Fermi Architecture.

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.

GPU
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 672MHz.

Memory
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.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Performance
GeForce GT 540M is essentially a fast GeForce GT 435M.
Gaming benchmarks put its performance only slightly below a desktop GeForce GT 430.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 540M.
