In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7400G are very slightly better than the Nvidia GeForce 320M.

The Radeon HD 7400G was released over a year more recently than the GeForce 320M, and so the Radeon HD 7400G 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 7400G and the GeForce 320M 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 7400G and the GeForce 320M are the same, which means the Radeon HD 7400G and the GeForce 320M have equal limitations when it comes to graphical data transfer.

The Radeon HD 7400G has 192 Shader Processing Units and the GeForce 320M has 48. However, the actual shader performance of the Radeon HD 7400G is 63 and the actual shader performance of the GeForce 320M is 45. The Radeon HD 7400G having 18 better shader performance is not particularly notable, as altogether the GeForce 320M performs better when taking into account other relevant data.

The Radeon HD 7400G requires 17 Watts to run and the GeForce 320M requires 23 Watts. The GeForce 320M requires 6 Watts more than the Radeon HD 7400G 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 7400G.

GPU Mini Review

Mini ReviewRadeon HD 7400G is an integrated GPU on the entry-level ULV Trinity CPUs.
It's based on the 32nm Terascale 3 architecture and offers 192 Shader Processing Units, 12 TMUs and 4 ROPs. The memory interface will depend on whether or not the laptop's system RAM is dual channelled (128-bit if so, 64-bit, if not) and the operating memory clock can be up to 667MHz (max speed supported by the CPU). The central unit runs at 327MHz and will go up to 424MHz in Turbo Mode. Expect a TDP of up to 17 Watt.
Its performance is below Intel HD 4000 Graphics but is slightly above next in series - Radeon HD 7420G, despite the naming, due to the extra Shaders which prove useful in most of today's modern games.
Most of today's modern games will have to be played at the lowest settings, while extremely demanding games (e.g. Crysis 3) are most likely unplayable.
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.
