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.

Video outputs and ports

Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.

Advantages of Intel HD Graphics 400

Lower power consumption (6W vs 15W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

Advantages of Intel UHD Graphics G4

Much newer (28 May 2020 vs 1 April 2015)

More pipelines (384 vs 96)

Finer manufacturing process technology (10 vs 14 nm)
