Technical specs
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.

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 Discontinued in January 2020, 3DMark 11 is now superseded by Time Spy.
Benchmark coverage: 16%
Iris Plus Graphics 645 outperforms UHD Graphics (Jasper Lake 24 EU) by 105% in 3DMark 11 Performance GPU.
3DMark Fire Strike Score
Benchmark coverage: 13%
Iris Plus Graphics 645 outperforms UHD Graphics (Jasper Lake 24 EU) by 66% in 3DMark Fire Strike Score.
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 seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic enough graphics and is quite taxing on hardware.
Benchmark coverage: 13%
Iris Plus Graphics 645 outperforms UHD Graphics (Jasper Lake 24 EU) by 71% in 3DMark Fire Strike Graphics.
