In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7490M are significantly better than the Nvidia GeForce 320M.

The Radeon HD 7490M has a 350 MHz higher core clock speed than the GeForce 320M, but the GeForce 320M has 8 more Texture Mapping Units than the Radeon HD 7490M. As a result, the GeForce 320M exhibits a 0.8 GTexel/s better Texture Fill Rate than the Radeon HD 7490M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 7490M has a 350 MHz higher core clock speed than the GeForce 320M, but the GeForce 320M has 4 more Render Output Units than the Radeon HD 7490M. As a result, the GeForce 320M exhibits a 0.4 GPixel/s better Pixel Fill Rate than the Radeon HD 7490M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 7490M was released over a year more recently than the GeForce 320M, and so the Radeon HD 7490M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 320M.

The Radeon HD 7490M has 1024 MB video memory, but the GeForce 320M does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 7490M has 160 Shader Processing Units and the GeForce 320M has 48. However, the actual shader performance of the Radeon HD 7490M is 64 and the actual shader performance of the GeForce 320M is 45. The Radeon HD 7490M having 19 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7490M delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 320M.

The Radeon HD 7490M requires 9 Watts to run and the GeForce 320M requires 23 Watts. The GeForce 320M requires 14 Watts more than the Radeon HD 7490M to run. The difference is not significant enough for the GeForce 320M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7490M.

GPU Mini Review

Mini ReviewOverview
Radeon HD 7490M is an Entry-Level 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 Seymour XTX which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit runs at 800MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 64-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 950MHz.

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

Power Consumption
With a rated board TDP of 9W, it is suited for smaller laptops.

Performance
Gaming benchmarks put its performance somewhat below a GeForce GT 420M.

System Suggestions
We recommend a Modest Processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7490M.
Overview
GeForce 320M is an Integrated Mobile Graphics Card based on the Second Revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed Tesla MCP89 which has 4 Stream Multiprocessors activated and thus offers 48 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is clocked at 450MHz.

Memory
The GPU also Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 256MB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Features
DirectX 10.1 Support (10.0 Hardware Default) and support for NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Power Consumption
With a rated board TDP of 14W, it may be used on very small notebooks.

Performance
Gaming benchmarks put its performance considerably above the desktop GeForce 210.
