GDDR5 is not supported according to Nvidia.Ī low power version of the GT 330M is also available for laptop manufacturers featuring a minimal slower clock rate and less power consumption (Codename N11P-LP).Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: Usually the GT 330M is paired with cheap and relatively fast DDR3 memory. With slow DDR2, the card can be up to 20% slower than with faster memory. In conjunction with an Core i5-520M, the GT 330M decoded H.264 with 1-6%, VC1 in 5-10%, and WMV with 3-9% CPU load (1080p over HDMI on a Sony Vaio Z11).Īs with the GT 230M, the performance depends on the used graphics memory. Hardware decoding of MPEG-1 encoded videos is not supported, but this can be handled by every CPU without high load. The integrated VP4 video processor is able to fully decode H.264, VC-1, MPEG-2, and MPEG-4 ASP (e.g., DivX, xVID). The GT330M supports the hardware decoding of HD videos using the integrated PureVideo HD engine. For example encoding videos using the stream processors is considerably faster than using a fast CPU. To use the calculation performance of the GeForce GT 330M for other applications, the card supports CUDA, OpenCL, and Direct Compute. The stream processors / shaders are 1-dimensional (1D) and can therefore not directly compared to the 5D shaders of current AMD / ATI cards like the Mobility Radeon HD 5650. According to Nvidia, the micro architecture was improved regarding battery runtime and performance. The 48 shader cores of the GT216 are based on the desktop GTX 200 architecture and are therefore a bit improved compared to the 48 cores of the GeForce 9700M GTX. See the gaming list below for detailed benchmarks. Less demanding games like Sims 3 run in high details and resolutions.

Modern and demanding DirectX 10 and 11 games (like Crysis or Risen) can only be played fluently with medium detail settings and resolution settings. The modern ATI Radeon HD 5650 offers DirectX 11 effects and performs better. The card supports DirectX 10.1 and all the features of the GT 230M / 240M (as it is based on the same GT216 core). The performance of the GT 330M is similar to the GeForce GT 240M and therefore located in the range of the Mobility Radeon HD 4650. Therefore, the GT330M is a mid-range laptop graphics card that offers DirectX 10.1 effects. The Nvidia GeForce GT 330M is the successor of the GT 230M and technically a faster clocked GT 240M (but it should still maintain the power envelope of the GT 230M as the naming suggests).
