Iris Plus Graphics 640 outperforms UHD Graphics G1 (Ice Lake 32 EU) by 27% based on our aggregated benchmark results.
3DMark 11 Performance GPU
3DMark 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 Discontinued in January 2020, 3DMark 11 is now superseded by Time Spy.

Iris Plus Graphics 640 outperforms UHD Graphics G1 (Ice Lake 32 EU) by 12% in 3DMark 11 Performance GPU.
3DMark Fire Strike Graphics
Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic graphics and is quite taxing on hardware.
Benchmark coverage: 14%
UHD Graphics G1 (Ice Lake 32 EU) outperforms Iris Plus Graphics 640 by 9% in 3DMark Fire Strike Graphics.
3DMark Cloud Gate GPU
Cloud Gate is an outdated DirectX 11 feature level 10 benchmark that was used for home PCs and basic notebooks.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.

Iris Plus Graphics 640 outperforms UHD Graphics G1 (Ice Lake 32 EU) by 1% in 3DMark Cloud Gate GPU.
3DMark Ice Storm GPU
Ice 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 Discontinued in January 2020, it is now superseded by 3DMark Night Raid.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%
Iris Plus Graphics 640 outperforms UHD Graphics G1 (Ice Lake 32 EU) by 53% in 3DMark Ice Storm GPU.
