Technical specs

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Pipelines / CUDA cores	32	16
Core clock speed	450 MHz	450 MHz
Number of transistors	486 million	282 Million
Manufacturing process technology	40 nm	65 nm
Thermal design power (TDP)	23 Watt	12 Watt
Texture fill rate	7.200	no data

Compatibility, dimensions and requirements

Information on GeForce 320M and GeForce 9400M (G) / ION (LE) compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

Interface

PCIe 2.0 x16

Memory

Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM.

Video outputs and ports

Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.

Display Connectors

No outputs

no data

API support

APIs supported, including particular versions of those APIs.

DirectX	11.1 (10_1)	10.0
Shader Model	4.1	no data
OpenGL	3.3	no data
OpenCL	N/A	no data
Vulkan	N/A	no data

Benchmark performance

Non-gaming benchmark performance comparison. Note that overall benchmark performance is measured in points in 0-100 range.
