NVIDIA GeForce RTX 3080 Ti (20 GB)

The NVIDIA GeForce RTX 3080 Ti (20 GB) is an end-of-life desktop graphics card that released in Q1 2022 with a MSRP of $1,199. It is built on the Ampere GPU microarchitecture (codename GA102) and is manufactured on a 8 nm process.

Memory

The RTX 3080 Ti has 20 GB of GDDR6X memory, with a 1,188 MHz memory clock and a 320 bit interface. This gives it a memory bandwidth of 760.3 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 3080 Ti includes 10,240 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,335 MHz and can dynamically boost its clock speed up to 1,665 MHz. Complementing the processing units are 320 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 320 tensor cores optimized for AI-accelerated workloads and 80 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RTX 3080 Ti occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 750 W to handle the GPU's thermal design power (TDP) of 350 W.
