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.
