Intel HD Graphics 515 vs NVIDIA Quadro K4000M vs NVIDIA Quadro K610M

Intel HD Graphics 515

The Intel HD Graphics 515 (GT2) is a low-end integrated graphics unit, which can be found in the Core m-series of the Skylake generation. This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1000 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 515 has to access the main memory (2x 64bit DDR3L-1600 / LPDDR3-1866).

Performance

According to Intel, the HD Graphics 515 is up to 41 percent faster than the previous HD Graphics 5300 (Broadwell). Nevertheless, the GPU will handle only simple games like Counter-Strike or Dota with decent frame rates. Depending on the specific CPU model, memory configuration and TDP (4.5 W, configurable), performance may vary substantially.

Features

The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4a (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.

Power Consumption

The HD Graphics 515 can be found in Core m processors with 4.5 W TDP (3.5/3.8 W cTDP down, 7 W cTDP up) and is therefore suited for very thin, mostly passively cooled 2-in-1 notebooks and tablets.

NVIDIA Quadro K4000M

The NVIDIA Quadro K4000M is a high-end, DirectX 11.1 compatible graphics card for mobile workstations. It is a Kepler-based GPU built on the GK104 chip (but using only 960 shader cores) and is manufactured in 28nm at TSMC. The Quadro K4000M is built for the Intel Chief River generation (Ivy Bridge) and is the successor to the Fermi-based Quadro 4000M (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 K4000M, 5 blocks are active leading to the 960 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). 

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 significantly above the level of the older Quadro 5010M and also beats the GeForce GTX 675M. Therefore, the card will manage both CAD software and demanding 3D games of 2013 in high quality 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 K4000M is rated at 100 Watt (TGP according to Nvidia) and is therefore suited for large-sized notebooks 17-inches or greater.

NVIDIA Quadro K610M

The NVIDIA Quadro K610M 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 192 out of 384 shader cores activated and is manufactured in 28nm at TSMC. The Quadro K610M is built for the Intel Shark Bay generation (Haswell) and is a successor to the Quadro K500M (Chief River platform). As a new feature, PCIe 3.0 is supported for the first time. The K610M usually comes with 1 GB GDDR5 VRAM clocked at 650 MHz (2600 MHz effective, 20.8 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 K610M, only one block is active leading to the 192 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 clearly above the old Quadro K500M (which has only DDR3 memory) and similar to the consumer GeForce GT 720M. However, most demanding games of 2013 will run fluently only in low detail settings.

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. Please note: The K610M does not supprt 3D Vision Pro.

Using CUDA or OpenCL 1.2, the cores of the Quadro K610M 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 K610M is rated at a TGP of 30 W including the board and memory components. Therefore, the card is suited for medium-sized notebooks with 15-inch displays or greater.
