Framework Modular Laptop Intel Raptor AMD Ryzen 7040 motherboard

Framework modular laptop adds Intel Raptor Lake, AMD Ryzen motherboards, 16-inch laptop frame

When we first covered the Framework modular laptop in 2021 it came with a choice of 11th generation Intel Tiger Lake Core processors, up to 64GB RAM, up to 4TB SSD storage, a 13.5-inch display, a Full HD webcam, and a 55Wh battery. Modular electronic devices have been worked on by several companies over the years, but such endeavors usually result in failure due to costs and other difficulties. Remember Google’s Project Ara?  But Framework may have found something that works, as they’ve now launched 13th Generation Intel Raptor Lake motherboards, AMD Ryzen 7040-series motherboards, updated the 13.5-inch display with a Matte finish, and even unveiled the Framework Laptop 16 with a 16-inch display that should become available in Q3 2023. Intel Raptor Lake and AMD Ryzen 7040 motherboards The Framework modular laptop now supports additional Intel Raptor Lake and AMD Ryzen motherboards with the following processors and key options. […]
