Intel Data Center GPU Flex 170

The Intel Data Center GPU Flex 170 is an end-of-life workstation graphics card that released in Q3 2022. It is built on the Xe-HPG GPU microarchitecture (codename DG2-512) and is manufactured on a 6 nm process.

Memory

The Data Center GPU Flex 170 has 16 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 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 Data Center GPU Flex 170 includes 4,096 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,950 MHz and can dynamically boost its clock speed up to 2,050 MHz. Complementing the processing units are 256 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 32 ray tracing units dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The Data Center GPU Flex 170 occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 2.0 display connections. Intel recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 150 W.
