NVIDIA GeForce RTX 2080 Mobile vs AMD Radeon R9 M390 (Mac Edition)

The NVIDIA GeForce RTX 2080 Mobile is a mobile graphics card that launched in Q1 2019. It is built on the Turing GPU microarchitecture (codename TU104) and is manufactured on a 12 nm process.

Memory

The RTX 2080 Mobile has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 448 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 2080 Mobile includes 2,944 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,380 MHz and can dynamically boost its clock speed up to 1,590 MHz. Complementing the processing units are 184 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 368 tensor cores optimized for AI-accelerated workloads and 46 RT cores dedicated to real-time ray tracing calculations.

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 RTX 2080 Mobile has the 60th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 33.36% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
