NVIDIA A2

The NVIDIA A2 is an end-of-life workstation graphics card that released in Q4 2021. It is built on the Ampere GPU microarchitecture (codename GA107) and is manufactured on a 8 nm process.

Memory

The A2 has 16 GB of GDDR6 memory, with a 1,563 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 200.1 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 A2 includes 1,280 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,440 MHz and can dynamically boost its clock speed up to 1,770 MHz. Complementing the processing units are 40 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing. Additionally, the GPU features 40 tensor cores optimized for AI-accelerated workloads and 10 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The A2 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. NVIDIA recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 60 W.
