NVIDIA Quadro K4100M
The NVIDIA Quadro K4100M is a high-end, DirectX 11 and OpenGL 4.3 compatible graphics card for mobile workstations. It is a Kepler-based GPU built on the GK104 chip with 1152 out of 1536 shader cores active and is manufactured in 28nm at TSMC. The Quadro K4100M is built for the Intel Shark Bay generation (Haswell) and is a successor to the Quadro K4000M (Chief River platform). As a new feature, PCIe 3.0 is supported for the first time. The K4100M usually comes with 4 GB GDDR5 VRAM clocked at 800 MHz (3200 MHz effective, 102.4 GB/s).
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.
The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. The GK104 Kepler core offers eight shader blocks, called SMX, that are clocked at the same speed as the central core. In the K4100M, 6 of 8 blocks are active leading to the 1152 CUDA cores. Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are still expected to be up to twice as power efficient. However, due to the missing hot clock of the shader domain, two shaders of a Kepler chip offer similar performance to just one shader of a Fermi chip (as the latter is clocked twice as fast).
The performance is clearly above the old Quadro K4000M and similar to the Quadro K5000M. In 3D games, the K4100M offers a performance slightly above the consumer GeForce GTX 770M. Therefore, most demanding games of 2013 will run fluently with maxed out details.
The improved feature set now includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840 x 2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. 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 1.2, the cores of the Quadro K4100M can be used for general calculations.
The 5th generation PureVideo HD video processor (VP5) is also integrated in the GK104 core and offers hardware decoding of HD videos. Common codecs such as MPEG-1/2, MPEG-4 ASP, H.264 and VC1/WMV9 are fully supported up to 4K resolutions while VC1 and MPEG-4 are supported up to 1080p. Two streams can be decoded in parallel for features such as Picture-in-Picture. Another novelty is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed by the NVENC API.
The power consumption of the Quadro K4100M is rated at a TGP of 100 W including the board and memory components. Therefore, the card is only suited for large notebooks with 17-inch displays or greater.
