Intel HD Graphics 520

► remove from comparison

*
TheIntel HD Graphics 520(GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Skylake generation. This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 520 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 520 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model. The fastest versions (Core i7-6600U) should perform similar to a dedicatedGeForce 820Mand will handle modern games (as of 2015) in low settings.

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


NVIDIA GeForce 920M

*
TheNVIDIA GeForce 920M(sometimes also NVIDIA GeForce GT 920M) is an entry level DirectX 12 graphics card. It is based on the 28 nm Kepler architecture and uses the same GK208 chip as theGeForce GT 730M, 825Mand740M. The 384 shaders are clocked at 954 MHz, while the memory (64-bit DDR3 interface) runs at 900 MHz (1800 MHz effective).

Architecture

GK208is based on the Kepler architecture and offers two shader blocks, calledSMX, each with 192 shaders for a total of384 shader cores.The shaders are clocked at the same speed as the rest of the chip. Furthermore, the GK208 chip has 16 TMUs and 8 ROPs on a 64-bit memory interface.

PCIe 3.0is now supported by the mobile Kepler series and GPU Boost 2.0 mode can automatically overclock the card if the laptop cooling system allows it.This feature is available on any notebook with a graphics card from the 800M series.

Performance

The GeForce 920M offers a performance similar to the AMD Radeon R7 M260 or R7 M360 and will handle modern games (as of 2014/2015) in low settings only. For comparison, a GeForce 930M is about 20 to 30 percent faster than the 920M.

Features

The feature set of the 920M corresponds to the GT 730M and 825M. This 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) 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 feature is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed via the NVENCI API.

Power Consumption

The power consumption of the GeForce 920M is similar to the 825M and suited for 13-inch laptops and above.


NVIDIA GeForce 945M

► remove from comparison

TheNVIDIA GeForce 945Mis a mid-range, DirectX 12-compatible graphics card for laptops unveiled in March 2015.It is based on Nvidia"s Maxwell architecture (GM107 chip) and manufactured in 28 nm. The 945M offers 512 shaders (compared to the 640 of the GTX 950M) clocked at 928 MHz. The dedicated DDR3 graphics memory is connected with a 128 Bit bus clocked at 1000 MHz (effective 2000, 32 GB/s).

Architecture

Compared to Kepler, Maxwell has been optimized in several details to increase power efficiency. Smaller Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an optimized scheduler should lead to better utilization of the shaders.Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90 percent of the performance of a Kepler SMX with 192 ALUs.GM107 features 5 SMMs and thus 640 shader cores, 40 TMUs and 16 ROPs (128-bit interface).

Another optimization is the massively enlarged L2 cache (GM107: 2 MB). The increased size can handle some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing the performance.

GM107 supports DirectX 12 with feature level 11_0 only.

Performance

The performance of the 945M is slightly worse than the GTX 950M but clearly faster than the 940M. The DDR3 variant of the GTX 950M is about 10 percent faster for example. Therefore, it is most suited for medium details of demanding games in 2015 (see below for benchmarks).

Features

GM107 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Of course, VP6 supports all features of previous generations (4K support, PIP, video encoding via NVENC API).Unfortunately,HDMI 2.0 is still not supported.

Power Consumption

The power consumption of the GeForce 945M should be somewhere around 40 Watt. Therefore it is most suited for bigger laptops from 14-inch and up.
