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 NVIDIA GeForce RTX 3080 Mobile

Somewhat newer (12 January 2021 vs 1 September 2020)

Wider memory bus (256 vs 192 bit)

More pipelines (6144 vs 2304)

Lower power consumption (115W vs 180W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

Advantages of AMD Radeon RX 6700M

Finer manufacturing process technology (7 vs 8 nm)
