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.

Compatibility, dimensions and requirements

Information on GeForce RTX 3080 Mobile and GeForce 6800 GT DDL compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

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

Much newer (12 January 2021 vs 14 April 2004)

Higher memory bandwidth (384 vs 32 GB/s)

Finer manufacturing process technology (8 vs 130 nm)

Advantages of NVIDIA GeForce 6800 GT DDL

Lower power consumption (80W vs 115W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

So, which one is the better GPU?

Technical City couldn't decide between NVIDIA GeForce RTX 3080 Mobile and NVIDIA GeForce 6800 GT DDL. We've got no test results to judge.

Be aware that GeForce RTX 3080 Mobile is a notebook card while GeForce 6800 GT DDL is a desktop one.
