40series

40series is a branding term used by several manufacturers to denote a generation of products within a family, typically following a 30-series or earlier generation. It is not a single product line, and there is no universal standard linking 40-series products across companies. The designation is common in consumer electronics and computer hardware, where manufacturers use numeric series to signal iteration, performance tier, or generation.

The most widely recognized 40-series is Nvidia GeForce RTX 40 Series of graphics processing units, introduced as the successor to the RTX 30 Series. Built on the Ada Lovelace architecture, the RTX 40 Series aims to deliver higher rendering performance, improved ray tracing, and enhanced AI-powered features. The lineup has included flagship models such as the RTX 4090 and RTX 4080 at launch, followed by mid-range cards like the RTX 4070 Ti and RTX 4060 Ti, with additional variants released over time. Availability and exact specifications vary by geography and product revision.

Beyond Nvidia, other manufacturers may use the 40-series branding for different generations of devices, including smartphones, peripherals, or enterprise hardware. In each case, the '40-series' label signals a generation step but does not guarantee a uniform set of capabilities.
