In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 320M are very slightly better than the AMD Radeon HD 6450M.

The Radeon HD 6450M has a 150 MHz higher core clock speed than the GeForce 320M, but the GeForce 320M has 8 more Texture Mapping Units than the Radeon HD 6450M. As a result, the GeForce 320M exhibits a 2.4 GTexel/s better Texture Fill Rate than the Radeon HD 6450M. 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 6450M has a 150 MHz higher core clock speed than the GeForce 320M, but the GeForce 320M has 4 more Render Output Units than the Radeon HD 6450M. As a result, the GeForce 320M exhibits a 1.2 GPixel/s better Pixel Fill Rate than the Radeon HD 6450M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 6450M was released less than a year after the GeForce 320M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 6450M 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 6450M has 160 Shader Processing Units and the GeForce 320M has 48. However, the actual shader performance of the Radeon HD 6450M is 48 and the actual shader performance of the GeForce 320M is 45. The Radeon HD 6450M having 3 better shader performance is not particularly notable, as altogether the GeForce 320M performs better when taking into account other relevant data.

The Radeon HD 6450M requires 11 Watts to run and the GeForce 320M requires 23 Watts. The GeForce 320M requires 12 Watts more than the Radeon HD 6450M 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 6450M.

GPU Mini Review

Mini ReviewRadeon HD 6450M is an entry-level GPU based on the 40nm Terrascale 2 architecture.
It's based on the Caicos Core (therefore related to Radeon HD 6450) and offers 160 Shader Processing Units, 8 TMUs and 4 ROPs on a 64-bit memory interface of standard DDR3. Its central clock runs at up to 600MHz and the memory clock operates at 800MHz.
Compared to Radeon HD 6470M, it should perform considerably worse due to being heavily underclocked.
Using a 720p resolution, almost all of today's games are only playable at low settings but with fluent frame rates (30+).
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.
