AMD Radeon HD 7870M vs NVIDIA RTX A2000 Mobile (8 GB)

The RTX A2000 Mobile (8 GB) is a graphics card by NVIDIA. It is built on the Ampere GPU microarchitecture and is manufactured on a 8 nm process.

Memory

The RTX A2000 Mobile has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 192 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 A2000 Mobile includes 2,560 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 893 MHz and can dynamically boost its clock speed up to 1,687 MHz. Complementing the processing units are 80 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing. Additionally, the GPU features 80 tensor cores optimized for AI-accelerated workloads and 20 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 95 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RTX A2000 Mobile has the 120th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 17.26% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
