General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked. Show

GeForce 940MX 3.90 +61.8% GeForce 940MX outperforms HD Graphics 620 by 62% in our combined benchmark results. PassmarkThis is the most ubiquitous GPU benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities. Benchmark coverage: 25% GeForce 940MX 1513 +61.8% GeForce 940MX outperforms HD Graphics 620 by 62% in Passmark. 3DMark Vantage Performance3DMark Vantage is an outdated DirectX 10 benchmark using 1280x1024 screen resolution. It taxes the graphics card with two scenes, one depicting a girl escaping some militarized base located within a sea cave, the other displaying a space fleet attack on a defenseless planet. It was discontinued in April 2017, and Time Spy benchmark is now recommended to be used instead. Benchmark coverage: 17% GeForce 940MX 8549 +47.3% GeForce 940MX outperforms HD Graphics 620 by 47% in 3DMark Vantage Performance. 3DMark 11 Performance GPU3DMark 11 is an obsolete DirectX 11 benchmark by Futuremark. It used four tests based on two scenes, one being few submarines exploring the submerged wreck of a sunken ship, the other is an abandoned temple deep in the jungle. All the tests are heavy with volumetric lighting and tessellation, and despite being done in 1280x720 resolution, are relatively taxing. Discontinued in January 2020, 3DMark 11 is now superseded by Time Spy. Benchmark coverage: 17% GeForce 940MX 2556 +69.4% GeForce 940MX outperforms HD Graphics 620 by 69% in 3DMark 11 Performance GPU. 3DMark Fire Strike GraphicsFire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic graphics and is quite taxing on hardware. Benchmark coverage: 14% GeForce 940MX outperforms HD Graphics 620 by 114% in 3DMark Fire Strike Graphics. 3DMark Cloud Gate GPUCloud Gate is an outdated DirectX 11 feature level 10 benchmark that was used for home PCs and basic notebooks. It displays a few scenes of some weird space teleportation device launching spaceships into unknown, using fixed resolution of 1280x720. Just like Ice Storm benchmark, it has been discontinued in January 2020 and replaced by 3DMark Night Raid. Benchmark coverage: 14% GeForce 940MX outperforms HD Graphics 620 by 49% in 3DMark Cloud Gate GPU. 3DMark Ice Storm GPUIce Storm Graphics is an obsolete benchmark, part of 3DMark suite. Ice Storm was used to measure entry level laptops and Windows-based tablets performance. It utilizes DirectX 11 feature level 9 to display a battle between two space fleets near a frozen planet in 1280x720 resolution. Discontinued in January 2020, it is now superseded by 3DMark Night Raid. Benchmark coverage: 8% GeForce 940MX 147706 +86.8% GeForce 940MX outperforms HD Graphics 620 by 87% in 3DMark Ice Storm GPU.
