NVIDIA NVS 5400M vs NVIDIA Quadro K2000M

NVIDIA NVS 5400M

The NVIDIA NVS 5400M is a middle-class graphics card for laptops and is based on the consumer GeForce GT 630M / 540M chip but with lower clock rates. At its core, the NVS 5400M is a 40nm GF108 Fermi chip with DirectX 11 support. The NVS series of mobile graphics cards is optimized for business applications (such as CAD or DCC) and stability.

NVIDIA Quadro K2000M

The NVIDIA Quadro K2000M (or K2100M due to an internal code name) is a mid-range, DirectX 11.1-compatible graphics card for mobile workstations. It is a Kepler-based GPU built using the GK107 chip and is manufactured in 28nm at TSMC.

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 GeForce graphics cards of similar specifications.

Architecture

The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. The GK107 Kepler core offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores that are clocked at the same speed as the central core. 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 are about as fast as one shader of a Fermi chip (as the latter is clocked twice as fast).

PCIe 3.0 is now supported by the mobile Kepler series and an optional Turbo mode can automatically overclock the Nvidia card by a theoretical 15 percent if the laptop cooling system allows it. The implementation of this boost mode is done in the BIOS, but it is ultimately dependent upon the manufacturer of the laptop.

Performance

Depending on the clock speeds,  the gaming performance should be similar or slower than the consumer GeForce GT 650M equipped with DDR3 graphics memory. Games of 2012 will run fluently on medium or high settings.

Features

The improved feature set now includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840x2160 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.

The 5th generation PureVideo HD video processor (VP5) is also integrated in the GK107 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 K2000M is rated at 55 Watt (TGP according to Nvidia) and therefore suited for medium-sized notebooks of 15-inches or greater.
