NVIDIA Quadro K3000M vs Intel HD Graphics 610

NVIDIA Quadro K3000M

The NVIDIA Quadro K3000M is a performance-class, DirectX 11.1-compatible graphics card for mobile workstations. It is a Kepler-based GPU built on the GK104 chip (but using only 576 shader cores) and is manufactured in 28nm at TSMC. The Quadro K3000M is built for the Intel Chief River generation (Ivy Bridge) and is the successor to the Fermi-based Quadro 3000M (Huron River platform).

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 GK104 Kepler core offers eight shader blocks, called SMX, that are clocked at the same speed as the central core. In the K3000M, 3 blocks are active leading to the 576 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 provide similar performance to just 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

The performance is slightly above the older Quadro 4000M based on the fermi architecture. Compared to consumer cards, the K3000M performs similar to the GeForce GT 750M. Games of 2013 can be played fluently in medium or high detail and resolution 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 K3000M is rated at 75 Watt (TGP according to Nvidia) and is therefore suited for medium-sized notebooks 17-inches or greater.

Intel HD Graphics 610

The Intel HD Graphics 610 (GT1) is an integrated graphics unit, which can be found in low-end ULV (Ultra Low Voltage) processors of the Kaby-Lake generation. This "GT1" version of the Skylake GPU offers 12 Execution Units (EUs) clocked at up to 950 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 610 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

The successor of the HD 610 is the renamed UHD Graphics 610 in the Whisky-Lake and Comet-Lake Pentium CPUs.

Performance

Depending on various factors like memory configuration, the HD Graphics 610 should similar to the old Skylake HD Graphics 510 and therefore can only handle non demanding games. E.g. Farming Simulator 17, World of Warships or Dota 2 Reborn can be played on low settings.

Features

The revised video engine now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The Pentium chips should already support HDCP 2.2 and therefore Netflix 4K. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The HD Graphics 610 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
