NVIDIA GeForce 610M The NVIDIA GeForce 610M is an entry level dedicated laptop graphics card and technically a renamed GeForce GT 520MX. It is based on the GF119 like the GT 520M, but features a higher core and shader clock rate. Using DDR3, the 64 Bit memory bus may become a bottleneck for the graphics card. 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) 610M has to compete against the Intel HD Graphics 3000 in the current Sandy Bridge processors. Due to the higher clock speeds, the MX should be faster than the GT 520M which was only slightly faster than the HD 3000 but clearly still behind the faster GT 525M. Therefore demanding games like Crysis 2 or Mafia 2 run fluently only in the lowest detail and resolutions. Less demanding games like Fifa 11 or Sims 3 should be playable even in high detail settings. Features Like 500M series chips, the 610M 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 610M 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 610M 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.
