Here are the Elgato 4K X System Requirements.

Using 4K X in recording and streaming software other than 4K Capture Utility software, such as OBS Studio, XSplit, StreamLabs Desktop, and others, will have different system requirements. 

System Requirements

Operating System

Windows:

• Windows 10 (64-bit)
• CPU: 6th generation Intel Core i5 CPU (i5-6xxx) / AMD Ryzen 5 (3600) or better
• GPU: NVIDIA GeForce GTX 10xx (or better)
• USB: 3.2 Gen 2 port (USB 3.2 Gen 1 works with reduced capture resolution)
• RAM: 8 GB RAM

macOS:

• macOS 11 Big Sur or later
• CPU: Apple M1 Chip or 4th generation quad‑core Intel Core i5 CPU (i5-4xxx or comparable)
• Graphics: Apple M1 integrated graphics or dedicated GPU (NVIDIA)
• USB: 3.2 Gen 2 port (USB 3.2 Gen 1 works with reduced capture resolution)
• RAM: 8 GB RAM

iPadOS:

• iPad with USB-C Port
  • List of iPads with USB-C
• iPadOS 17 or newer
  
  • List of iPads that support iPadOS 17
• Internet connection

*A processor with a suffix like "U" (Ultra-low voltage) or "M" is not recommended since it will have significantly lower performance.  For example, the i7-4510U might seem powerful, but the U suffix indicates that it performs much less than other i7 processors.

Intel Pentium and Celeron processors do not meet the minimum specifications.

Windows GPU requirements

These GPU requirements are based on video encoding acceleration in the Elgato 4K Capture Utility software. Encoding support in software such as OBS Studio will differ. 

NVIDIA

• 4K60 HDR - GeForce 10xx (GTX 1050) or better
• 4K60 SDR - GeForce GTX 9xx (GTX 950) or better

AMD

• 4K60 SDR or 1080p60 SDR - Radeon RX Vega or better

Windows RAM requirements

• 8GB or more 
• Memory operating in dual-channel (This requires two or more physical sticks of RAM installed)
