NVIDIA GeForce 705M

The NVIDIA GeForce 705M or GeForce GT 705M is an entry level dedicated laptop graphics card and based on the same GF119 chip like the Geforce GT 520MGeForce GT 520MX and GeForce GT 610M. The clock speed of the chip is currently rumored to be 775 MHz but as with the 610M, they may vary from laptop to laptop.

Architecture

The GF119 offers 48 ALUs, 8 texture units and a 64 Bit memory interface for DDR3-VRAM. Therefore, it is similar to a half GF108 (GeForce GT 540M) but is manufactured with optimized transistors. As a difference the amount of raster-operation-processors (ROP) stayed the same at 4. The GF119 is the smallest chip of the Fermi generation and is used for low-end laptops.

Performance

As an entry level card, the (GT) 705M has to compete against the HD Graphics 4000. The performance depends on the chip clock speeds and therefore ranges between the GeForce GT 520M and GT 520MX (see links for gaming benchmarks). Therefore demanding games like Crysis 2 or Mafia 2 run fluently only in the lowest detail and resolutions. Less demanding games like Fifa 12 or Sims 3 should be playable even in high detail settings.

Features

Like 500M series chips, the 705M supports Bitstream HD Audio (Blu-Ray) output via HDMI. That means the card is able to transfer Dolby True HD and DTS-HD bitstream-wise to a HiFi receiver without quality loss.

The 705M offers the PureVideo HD technology for video decoding. The included Video Processor 5 (VP5) supports feature set D and therefore the GPU 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). Compared to the older VP4, the VP5 offers faster decodes at lower power, HD-to-SD transcodes and 4K x 4K resolution H.264 decode support.

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

Through CUDA, OpenCL, and DirectCompute 2.1 support, the GeForce GT 705M can be of help in general calculations. For example, the stream processor can encode videos considerably faster than a fast CPU can. Furthermore, physics calculations can be theoretically done by the GPU using PhysX (e.g. supported by Mafia 2 or Metro 2033) but the performance will not be sufficient for this.

The power consumption should be similar to the GeForce 610M and therefore suited for small laptops.
