The Nvidia Quadro M4000M is a high-end, DirectX 12 (FL_12_1) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a Maxwell-based GPU built on the GM204 chip with all 1280 of the 1536 shader cores activated and is manufactured in 28 nm at TSMC. Therefore, the GPU is similar to the consumer Nvidia GeForce GTX 970M. The Quadro M4000M is built for the Intel Skylake generation and is a successor to the Quadro K4100M (Kepler-based). The M4000M usually comes with 4 GB GDDR5 VRAM clocked at 1250 MHz (5000 MHz effective, 160 GB/s opposed to 102.4 GB/s of the K4100M).
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 compared to GeForce graphics cards of similar specifications.
Performance
The clock speeds of the Quadro M4000M are very similar to the GTX 970M based on the same chip. The base clock is slightly higher with 975 versus 924 MHz but the Boost speed is lower at 1013 versus 1038 MHz. Therefore, with good cooling the GTX 970M should be slightly faster. Compared to the Quadro line-up, it is the second fastest Quadro card in 2015 and therefore clearly faster than the old Quadro K4100M.
Using CUDA (Compute Capability 5.2) or OpenCL 1.2, the cores of the Quadro M4000M can be used for general calculations.
Power Consumption
The power consumption of the Quadro M4000M is rated at the same TGP of 100 Watt as the M5000M and older K5100M/K4100M (including the board and memory components). Therefore, the card is suited for large notebooks with 17-inch displays or greater.
The NVIDIA Quadro 4000M is a professional workstation graphics card based on the Fermi architecture (or more specifically, probably the GF104). Unlike the 5010M, the 4000M does not support ECC memory and dual-precision (DP) floating point calculations.
The Quadro series offers certified drivers that are optimized for stability and performance in professional applications such as CAD or DCC. As a result, multiple scientific or business disciplines can make use of the workstation GPU. The OpenGL performance, for example, should be significantly better than consumer-oriented GeForce graphics cards of similar specifications.
The shader / CUDA cores can be accessed using DirectX 11 or OpenGL 4.1 for graphics rendering or DirectCompute, OpenCL, AXE, and CUDA for general purpose calculations. Due to the new Fermi core, the 4000M should offer higher performance in general purpose calculations compared to its predecessors.
Furthermore, the Nvidia Quadro 4000M is compatible with 3D Vision Pro, a new software solution by Nvidia for stereoscopic output.
The 4000M supports Nvidia Optimus in order to automatically switch between the integrated graphics card and the Quadro for power-saving purposes. Whether or not this feature is supported on a laptop, however, is dependent on the laptop manufacturer.
Similar to the GeForce GTX 480M, the Quadro 4000M is specified at 100 Watt TDP and is therefore only found in large laptops such as the Clevo D901F.
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.
Architecture
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.
Performance
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.
Features
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).
Power Consumption
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.
