NVIDIA GeForce RTX 4080 Mobile vs NVIDIA GeForce GTX 1660 Ti Mobile

The NVIDIA GeForce RTX 4080 Mobile is a mobile graphics card that launched in Q1 2023. It is built on the Ada Lovelace GPU microarchitecture (codename AD104) and is manufactured on a 5 nm process.

Memory

The RTX 4080 Mobile has 12 GB of GDDR6 memory, with a 2,250 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 432 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 RTX 4080 Mobile includes 7,424 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,290 MHz and can dynamically boost its clock speed up to 1,665 MHz. Complementing the processing units are 232 texture mapping units (TMUs) for efficient texture filtering and 80 render output units (ROPs) for pixel processing. Additionally, the GPU features 232 tensor cores optimized for AI-accelerated workloads and 58 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 110 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RTX 4080 Mobile has the 20th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 54.28% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
