![]() However, as most laptops will feature Optimus, the integrated GPU will likely have direct control over the display ports and may limit the feature set available by the Nvidia Kepler cards. HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. Furthermore, high resolution monitors of up to 3840x2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. The feature set includes support for up to 4 active displays. In older titles, there are also reserves for additional quality features like AA and AF. Current games (as of 2013) can be played fluently in medium to high settings. Models with GDDR5 memory are usually slightly faster than models with DDR3. This feature is available on any notebook with a graphics card of the 700M series.ĭepending on clock speed and memory configuration, the GT 745M performs just below the GT 650M or GTX 660M. PCIe 3.0 is now supported by the mobile Kepler series and GPU Boost 2.0 can automatically overclock the card if the laptop cooling system allows it. However, due to the missing hot clock of the shader domain, two shaders of a Kepler chip are as fast as one shader of a Fermi chip, even though Fermi shaders are clocked at twice the speed. Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are expected to be up to two times more power efficient. The GK107 Kepler core offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores that are clocked at the same speed as the processor core. The GK107 chip (384 shaders) is clocked at up to 837 MHz plus boost and has a 128 bit memory interface (usually DDR3, but GDDR5 also possible). It is based on the Kepler architecture and manufactured by TSMC in a 28-nanometer process. The NVIDIA GeForce GT 745M is a DirectX 11 graphics card of the middle class. NVIDIA GeForce GT 745M ► remove from comparison The implementation of Optimus, however, is dependent on the laptop manufacturer. Furthermore, the 600M series supports Optimus to automatically switch between the integrated Intel graphics card and the Nvidia GPU. If idle or not under load, the chip is clocked at approximately 50/101/137 MHz (chip/shader/memory, respectively) in 2D mode and at 202/405/324 MHz in 3D mode to save power. The power consumption of the GeForce GT 630M should be similar to the GeForce GT 435M or Radeon HD 5730 and is therefore suited for 15" or larger laptops. ![]() This feature is disabled if the notebook includes Optimus. This enables the laptop to send 3D content (3D games, 3D Web Streaming, 3D photos, 3D Blu-Rays) to a built-in 3D enabled screen or an external 3D TV if supported by the laptop manufacturer. However, the GPU is not powerful enough to support both PhysX and high detail game settings at reasonable frame rates.įollowing the current 3D trend, the 630M supports 3D Vision. Furthermore, physics calculations can be done by the GPU using PhysX (supported in Mafia 2 and Metro 2033). For example, the stream processor can encode videos considerably faster than can a modern CPU. Through CUDA, OpenCL, and DirectCompute 2.1 support, the GeForce GT 630M can assist in general calculations. Furthermore, the GPU is able to decode two 1080p streams simultaneously (e.g., for Blu-Ray Picture-in-Picture). The integrated Video Processor 4 (VP4) supports feature set C and is able to 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, and Deblocking). The GT 630M offers PureVideo HD technology for video decoding using the GPU. ![]() Similar to the Radeon HD 5730, the GT 630M can transfer Dolby True HD and DTS-HD bitstream without quality loss to a HiFi receiver. However, exact clock rates differ between laptop models and manufacturers the overall performance is somewhere between a GT 540M and GT 555M.Ī novelty of the GF104, GF106 and GF108 chips is the support for Bitstream HD Audio (Blu-Ray) via HDMI. The GF117 version can be clocked up to 800 MHz and therefore performs similar to the average GT 555M. However, certain 2011 games like Anno 2070 or Skyrim may need reduced detail settings for fluent framerates. Demanding games of 2010 should therefore run fluently in medium to high details. The performance of the 96 shader version should be exactly like the GeForce GT 540M and the 144 shader version like the GeForce GT 555M (see both gaming benchmark pages). Details on the GF117 can be found on the GeForce GT 620M page. More details on the GF108 and GF106/116 architecture can be found on the dedicated pages of the GeForce GT 435M and GeForce GT 555M.
