NVIDIA Quadro M520 vs NVIDIA Quadro 3000M

The Nvidia Quadro M520 is a DirectX 12 (FL 11_0) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a Maxwell-based GPU built on the GM108 chip with 384 shader cores and manufactured in 28 nm by TSMC. That means its similar to the Quadro M500M (DDR3) but uses faster GDDR5 memory. The GeForce 940MX with GDDR5 memory is the consumer variant of the Quadro M520.
The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD or DCC. OpenGL performance, for example, should be significantly better than with GeForce graphics cards of similar specifications.
Compared to Kepler, Maxwell has been optimized in several details to increase power efficiency. Smaller Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an optimized scheduler should lead to better utilization of the shaders. Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90% of the performance of a Kepler SMX with 192 ALUs. GM108 features 3 SMMs and thus 384 shader cores, 24 TMUs and 8 ROPs (64-bit interface).
Another optimization is the massively enlarged L2 cache. The larger size can reduce some of the memory traffic to allow for a relatively narrow memory interface without significantly hurting performance.
GM108 supports DirectX 11.2 (feature level 11.0 only) as well as DirectX 12.
Currently the clock speeds are not known of the M520 variant. They should be similar to the consumer 940 MX with GDDR5. Therefore, the performance should be similar to the Quadro K620M.
The feature set should include support for up to four active displays. High-resolution monitors of up to 3840x2160 pixels can be connected using DisplayPort 1.2 or HDMI 1.4a (HDMI 2.0 not supported). HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. 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.
Using CUDA or OpenCL, the cores of the Quadro M520 can be used for general calculations.
GM108 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Of course, VP6 supports all features of previous generations (4K support, PIP, video encoding via NVENC API).
The power consumption of the Quadro M520 is rated at 25 Watt TGP (max power consumption including memory and board). That is slightly below the M500M that is rated at 30 Watt. Therefore, the GPU is best suited for laptops 13 - 14-inches in size and above. The M500M also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU.

The NVIDIA Quadro 3000M is a professional workstation graphics card based on the Fermi architecture (probably GF104 like the GeForce GTX 470M). Compared to the 5010M, the 3000M does not support ECC memory and DP floating point calculations.
The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD, DCC, medicine, or visualisation areas. The OpenGL performance for example should be significantly better than similar specified GeForce graphics cards.
The shader / CUDA cores can be accessed using DirectX 11, OpenGL 4.1 for graphic rendering and DirectCompute, OpenCL, AXE, and CUDA for general purpose calculations. Due to the new Fermi core, the 3000M should offer a high performance in general purpose calculations.
Furthermore, the Nvidia Quadro 3000M is compatible with the new stereoscopic solution by Nvidia called: NVIDIA 3D Vision Pro.
To automatically switch between the processor graphics card and the Quadro, the 3000M supports Nvidia Optimus (if the laptop vendor chooses to integrate it).
As the GeForce GTX 470M, the Quadro 3000M is specified at 75 Watt TDP and therefore only suited for large laptops with 17 inch displays.
