NVIDIA GeForce GTX 675M

NVIDIA GeForce GTX 675M

The NVIDIA GeForce GTX 675M is a the fastest single-GPU laptop graphics card as of March 2012. It is based on the GF114 Fermi core and is essentially a renamed version of th GeForce GTX 580M but with higher core clock rates. Therefore, it is still manufactured in 40nm at TSMC.

GF114 architecture

The GF114 core is a power-optimized version of the GF104 used in the GTX 470M, but with no major architectural changes. Therefore, the performance per MHz of the GF114 stays the same even though Nvidia was able to clock the shaders higher while still remaining in the same power scale. The GTX 675M offers 384 cores at a clock speed of 620 MHz. More informations on the similar GF104 architecture can be found on the GeForce GTX 485M page.

Performance

Due to similar clock speeds, the GeForce GTX 675M is as fast as the old GTX 580M and is this noticeably more powerful than the GTX 670M and AMD Radeon HD 6970M. Current games as of 2011 should therefore run fluently in Full HD resolution and maximum details. Only a few very demanding games, such as Metro 2033, may need slightly reduced graphical settings for smoother gameplay.

Features

Similar to the older GF104 chip, the GF114 supports Blu-Ray Bitstream HD Audio output via HDMI. This means the GPU can transfer, for example, Dolby True HD or DTS-HD bitstream without quality loss to a HiFi receiver.

The GTX 670M offers PureVideo HD technology for video decoding. The included 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). 

Furthermore, the GPU is able to decode two 1080p streams simultaneously (e.g., Blu-Ray Picture-in-Picture).

Through CUDA, OpenCL, and DirectCompute 2.1 support, the GeForce GTX 675M can be used for general calculations. For example, the stream processor can encode videos considerably faster than can many modern CPUs. Furthermore, physics calculations can be done by the GPU using PhysX if supported (e.g., in Mafia 2 or Metro 2033).

3D Vision 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.

The power consumption of the GeForce GTX 675M should be the same as of the old GTX 580M, which is rumored to be about 100 Watt (TDP including the MXM board and memory). If not under load, the chip is clocked at 50/100 MHz (chip/shader) and 200/400 MHz in 2D and 3D mode, respectively, for power-saving purposes. Furthermore, the 600M series supports Optimus to automatically switch between the Intel integrated graphics card and the Nvidia GPU. Whether or not a laptop includes this feature is dependent on the manufacturer.
