NVIDIA GeForce 315M
The Nvidia GeForce 315M is an entry level graphics card for laptops and technically a sligthly lower clocked GeForce 310M. It is also based on the GT218 core that was introduced with the G 210M.
The performance of the 315M is similar to the GeForce 310M / G 210M and therefore located in the entry level class. Modern 3D games like COD Modern Warfare 2 run only in low details and resolutions fluently. Some demanding games like NFS Shift or GTA4 wont run fluently at all. Less demanding games like SIMS 3 run in medium details and resolutions fluently. Therefore, the graphics card can not be recommended for gamers.
The card supports DirectX 10.1 and all the features of the G 210M. Therefore PureVideo HD to decode HD videos with the graphics card is supported. The used Video Processor 4 (VP4) is able to fully decode H.264, VC-1, MPEG-2, and also MPEG-4 ASP (DivX or xVID) in hardware to minimize CPU load. MPEG-1 is not supported but can be easily handled by every modern CPU.
As the 315M supports CUDA, DirectX Compute 10.1, and OpenCL, the shaders of the graphics processor can be used for other tasks than rendering images (e.g. faster encoding of videos).
The used GT218 core is manufactured in 40nm and based on the desktop GTX 200 architecture. Therefore, the shaders have been reworked compared to the old GeForce G110M for an improved performance and battery runtime.
