NVIDIA Quadro K1100M vs NVIDIA Quadro M600M

NVIDIA Quadro K1100M

The NVIDIA Quadro K1100M is a DirectX 11 and OpenGL 4.3 compatible graphics card for mobile workstations. It is a Kepler-based GPU built on the GK107 chip with all 384 shader cores activated and manufactured in 28nm at TSMC. The Quadro K1100M is built for the Intel Shark Bay generation (Haswell) and is a successor to the Quadro K1000M (Chief River platform). As a new feature, PCIe 3.0 is supported for the first time. The K1100M usually comes with 2 GB GDDR5 VRAM clocked at 700 MHz (2800 MHz effective, 44.8 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.

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, that are clocked at the same speed as the central core. In the K1100M, both blocks are active leading to the 384 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).

Performance

The performance is similar to the old Quadro K2000M and clearly superior to the Quadro K1000M. This places the K1100M in range of the consumer GeForce GT 740M and GT 645M GPUs. Most demanding games of 2013 will run fluently with medium details and resolutions.

Features

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 K1100M can be used for general calculations.

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 Quadro K1100M is rated at a TGP of 45 W including the board and memory components. Therefore, the card is suited for medium-sized notebooks with 15-inch displays or greater.

NVIDIA Quadro M600M

The 28nm NVIDIA Quadro M600M is an entry-level DirectX 12 (FL 11_0) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a 1st generation Maxwell GPU that is most likely built on the GM107 architecture with 384 of the 640 shader cores activated. Compared to the older Quadro K620M and consumer GeForce 940M, the GPU offers a 128-Bit memory bus that separates it from the GM108-based K620M. The M600M typically comes with 2 GB GDDR5 VRAM clocked at 1250 MHz (5000 MHz effective at 80 GB/s instead of 16 GB/s on the K620M). 

In the Lenovo Thinkpad P70 the M600M is clocked at 837 - 876 MHz (Boost) for the shaders, and 1253 MHz (5012 MHz effektive) for the 2 GB GDDR5 from Samsung (thanks to our reader John for the GPU-Z screenshot).

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 Quadro M600M is about 20% faster than the previous Quadro K620M thanks to the wider 128-bit memory interface and pretty much right between the siblings Quadro M500M & Quadro M1000M. The consumer GPU GeForce 940MX is beaten by ~10-15%, while the GeForce GTX 950M is another 20% faster.

Using CUDA (Compute Capability 5.0) or OpenCL 1.2, the cores of the Quadro M600M can be used for general calculations.

Power Consumption

The power consumption of the Quadro M600M is rated at the same 30 Watt TGP as the K620M including the board and memory components. Therefore, the card is also suited for thin and light notebooks.
