In conjunction with a chipset from Nvidia with integrated graphics (e.g. MPEG-1 still wont be supported, but the decoding of this codec is quite trivial on a CPU.
The Video Processor 4 (VP4) supports the full decoding of H.264, VC-1, and now also MPEG-4 ASP (e.g. The mobile graphics card has a built in video decoder called PureVideo HD with VP4. For these special tasks, the GPU can be noticeably faster than current CPUs. The GeForce GT240M also supports CUDA, DirectX Compute, OpenCL, and PhysiX to use the shaders for other tasks than rendering images (like encoding videos, calculating the physics of a game or mathematical tasks). The unified shaders of Nvidia are 1-dimensional (AMD has 5-dimensional shaders which leads to the higher number of shaders). Therefore, the performance per shader unit should be slightly improved compared to the previous generation.Īs the GeForce 9700M GTS, the GT 240M features 48 stream processors that do the work of the former dedicated pixel- and vertex-shaders. Furthermore, Nvidia has improved the micro-architecture for further power saving and performance increases. The core of the GT230M is internally called GT216 and according to Nvidia based on the current high-end desktop architecture (GTX 200 series). The GT240M was later succeeded by the very similar GT330M (slightly higher clocked). Because of the 48 shader cores, it should perform noticeably better than the GT 130M and due to the 40nm production process the power consumption should stay the same. It is the successor of the GT 130M and technically a higher clocked GT 230M. – GLSL (OpenGL Shading Language) Version: 3.The Nividia GeForce GT 240M is a DirectX 10.1 graphics adapter for notebooks based on the GT216 core. – Clocks level #2: Core: 550MHz – Memory: 790MHz – Shader: 1340MHz – Clocks level #1: Core: 405MHz – Memory: 324MHz – Shader: 810MHz – Clocks level #0: Core: 135MHz – Memory: 135MHz – Shader: 270MHz – OpenGL Renderer: GeForce GT 240/PCI/SSE2 Here are sone additional information from GPU Caps Viewer: The difference comes from the GPU architecture: the GeForce GT 240 is a DX10.1 GPU while GTX 2xx are based on a DX10 GPU.Īnyway, the GeForce GT 240 exposes a total of 218 OpenGL extensions. Why the GT 240 exposes OpenGL 4.0 extensions and not other high end cards such as the GTX 260, GTX 280 or GTX 295 ? I have currently no answer…
My test bed runs with Windows 7 64-bit and the graphics drivers used are the R197.15.Ī GTX 2xx exposes 212 OpenGL extensions (the complete list is available HERE).Īfter a quick inspection, it turns out that these extra extensions are OpenGL 4.0 ones. I recently received a Zotac GeForce GT 240 and I was surprised to discover that this model of GeForce exposes more OpenGL extensions that a GeForce GTX 2xx (GTX 260 or GTX 280).
