However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously. 3840 x 2160 60 Hz), whereas HDMI is limited to the older version 1.4a (max. Displays can be connected via DP 1.2 / eDP 1.3 (max. The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. The fastest versions ( Core i7-6600U) should perform similar to a dedicated GeForce 820M and will handle modern games (as of 2015) in low settings. The exact performance of the HD Graphics 520 depends on various factors like 元 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific 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). This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). The Intel HD Graphics 520 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Skylake generation.

The 900M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU.ĭirectX 12 (FL 11_0), Shader 5.0, OpenGL 4.5 Therefore, the GPU is best suited for laptops 13 - 14 inches in size and above. The power consumption of the GeForce 940M should be about 30 Watts or lower. 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. GM108 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. However, very demanding games such as Assassin's Creed Unity will require lower resolutions and/or details. Similar to Fermi and Kepler, the GM107/GM108 support DirectX 12 with feature level 11_0 only.ĭue to its just 5 percent higher core clock, the GeForce 940M is only marginally faster than the previous GeForce 840M and similar to the older GeForce GT 750M (DDR3 version). Many games of 2014/2015 can be played fluently in WXGA resolution (1366 x 768) and medium detail settings. The larger size can process some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing performance. 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. GM108 features 3 SMMs and thus 384 shader cores, 24 TMUs and 8 ROPs (64-bit interface).Īnother optimization is the massively enlarged L2 cache. The 940M offers 384 shader units as well as 2 GB of DDR3 memory (64 bit, 2000 MHz effective).Ĭompared to the previous and technically very similar GeForce 840M, the GeForce 940M is clocked just slightly higher.Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The NVIDIA GeForce 940M is a mid-range DirectX 11-compatible graphics card for laptops unveiled in March 2015. It is based on Nvidia's Maxwell architecture (GM108 chip) and manufactured in 28 nm.
