Positioned in the enthusiast tier, it exists to give creators more cores and memory bandwidth than mainstream desktop chips. It’s a good fit for streaming, video editing, 3D rendering, and 1440p gaming with a discrete GPU. It’s unlocked for overclocking and has no integrated graphics. The i9‑9900X is discontinued; Intel’s PCN set last orders for January 22, 2021 and final shipments by July 9, 2021 (ARK lists status as discontinued).
