About the NVIDIA A100 (80 GB) GPU

The NVIDIA A100 (80 GB) is a workstation graphics card that launched in Q2 2021. It is built on the Ampere GPU microarchitecture (codename GA100) and is manufactured on a 7 nm process.

Memory

The A100 has 80 GB of HBM2e memory, with a 1,512 MHz memory clock and a 5,120 bit interface. This gives it a memory bandwidth of 1.94 Tb/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 A100 includes 6,912 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,065 MHz and can dynamically boost its clock speed up to 1,410 MHz. Complementing the processing units are 432 texture mapping units (TMUs) for efficient texture filtering and 160 render output units (ROPs) for pixel processing. Additionally, the GPU features 432 tensor cores optimized for AI-accelerated workloads.

Compatibility & Power Consumption

The A100 occupies 2 PCIe expansion slots. NVIDIA recommends a power supply of at least 700 W to handle the GPU's thermal design power (TDP) of 300 W.

About the NVIDIA A100 (40 GB) GPU

The NVIDIA A100 (40 GB) is a workstation graphics card that launched in Q2 2020. It is built on the Ampere GPU microarchitecture (codename GA100) and is manufactured on a 7 nm process.

Memory

The A100 has 40 GB of HBM2e memory, with a 1,215 MHz memory clock and a 5,120 bit interface. This gives it a memory bandwidth of 1.56 Tb/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 A100 includes 6,912 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 765 MHz and can dynamically boost its clock speed up to 1,410 MHz. Complementing the processing units are 432 texture mapping units (TMUs) for efficient texture filtering and 160 render output units (ROPs) for pixel processing. Additionally, the GPU features 432 tensor cores optimized for AI-accelerated workloads.

Compatibility & Power Consumption

The A100 occupies 2 PCIe expansion slots. NVIDIA recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.
