Nvidia geforce gt 630m


TheNVIDIA GeForce GT 630Mis a relatively fast middle-class graphics card for laptops. Currently, it can be based on three different chips with different specifications và performance values. TheGF108 version(a renamed GT 540M) features 96 shaderswhile theGF106/GF116 version(a renamed GT 550M) features 144 shaders. Furthermore, the newer 28nm Fermi-based GF117 variant will be available as well with significantly reduced power consumption.All models feature a 128 Bit memory interface for DDR3 graphics memory. As part of the Fermày architecture, the cards tư vấn DirectX 11 and OpenGL 4.0.

More details on the GF108 & GF106/116 architecture can be found on the dedicated pages of theGeForce GT 435MandGeForce GT 555M. Details on the GF117 can be found on theGeForce GT 620M page.


The performance of the 96 shader version should be exactly lượt thích theGeForce GT 540Mvà the 144 shader version like theGeForce GT 555M(see both gaming benchmark pages). Demanding games of 2010 should therefore run fluently in medium to high details. However, certain 2011 games like Anno 2070 or Skyrlặng may need reduced detail settings for fluent framerates. The GF117 version can be clocked up lớn 800 MHz and therefore performs similar lớn the average GT 555M. However, exact clock rates differ between máy tính models & manufacturers; the overall performance is somewhere between a GT 540M & GT 555M.


A novelty of the GF104, GF106 và GF108 chips is the tư vấn forBitstream HD Audio(Blu-Ray) via HDXiaoMi MI. Similar to the Radeon HD 5730, the GT 630M can transfer Dolby True HD and DTS-HD bitstream without chất lượng loss to a HiFi receiver.

The GT 630M offersPureVideo HDcông nghệ for video clip decoding using the GPU. The integrated Video Processor 4 (VP4) supports feature mix C và is able khổng lồ fully decode MPEG-1, MPEG-2, MPEG-4 Part 2 (MPEG-4 ASP - e.g., DivX or Xvid), VC-1/WMV9, and H.264 (VLD, IDCT, Motion Compensation, & Deblocking). Furthermore, the GPU is able to lớn decode two 1080p streams simultaneously (e.g., for Blu-Ray Picture-in-Picture).

ThroughCUDA, OpenCL, and DirectCompute 2.1support, the GeForce GT 630M can assist in general calculations. For example, the stream processor can encode videos considerably faster than can a modern CPU. Furthermore, physics calculations can be done by the GPU usingPhysX(supported in Mafia 2 & Metro 2033). However, the GPU is not powerful enough to tư vấn both PhysX and high detail game settings at reasonable frame rates.

Following the current 3 chiều trend, the 630M supports3D Vision. This enables the laptop to send 3D content (3D games, 3 chiều Web Streaming, 3D photos, 3D Blu-Rays) to lớn a built-in 3 chiều enabled screen or an external 3 chiều TV if supported by the máy vi tính manufacturer. This feature is disabled if the notebook includes Optimus.

Thepower consumptionof the GeForce GT 630M should be similar khổng lồ the GeForce GT 435M or Radeon HD 5730 and is therefore suited for 15" or larger laptops. If idle or not under load, the chip is clocked at approximately 50/101/137 MHz (chip/shader/memory, respectively) in 2D mode và at 202/405/324 MHz in 3 chiều mode khổng lồ save sầu power. Furthermore, the 600M series supportsOptimuslớn automatically switch between the integrated Intel graphics thẻ & the Nvidia GPU. The implementation of Optimus, however, is dependent on the máy tính manufacturer.
