AMD Instinct MI100

The AMD Instinct MI100 is an end-of-life workstation graphics card that released in Q4 2020. It is built on the CDNA 1.0 GPU microarchitecture (codename Arcturus) and is manufactured on a 7 nm process.

Memory

The Instinct MI100 has 32 GB of HBM2 memory, with a 1,200 MHz memory clock and a 4,096 bit interface. This gives it a memory bandwidth of 1.23 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 Instinct MI100 includes 7,680 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,000 MHz and can dynamically boost its clock speed up to 1,502 MHz. Complementing the processing units are 480 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The Instinct MI100 occupies 2 PCIe expansion slots. AMD recommends a power supply of at least 700 W to handle the GPU's thermal design power (TDP) of 300 W.
