NVIDIA GeForce GTX 1080 Mobile vs NVIDIA GeForce GTX 680MX (Mac Edition)

The NVIDIA GeForce GTX 1080 Mobile is an end-of-life mobile graphics card that released in Q3 2016. It is built on the Pascal GPU microarchitecture (codename GP104B) and is manufactured on a 16 nm process.

Memory

The GTX 1080 Mobile has 8 GB of GDDR5X memory, with a 1,251 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 320.3 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The GTX 1080 Mobile includes 2,560 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,557 MHz and can dynamically boost its clock speed up to 1,734 MHz. Complementing the processing units are 160 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 150 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GTX 1080 Mobile has the 82nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 27.27% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
