Switch Lite primarily a handheld system, but otherwise compatible with most of the Switch's library of games. Other eighth generation hardware Virtual reality systems appeared during the eighth generation, with three main systems: the PlayStation VR headset that worked with PlayStation 4 hardware, the Oculus Rift and the HTC Vive which ran off a personal computer. Ninth generation (2020–present) Both Microsoft and Sony released successors to their home consoles in November 2020. Consoles in this generation also launched with lower-cost models lacking optical disc drives, targeting those who would prefer to purchase games exclusively through digital downloads. Both console families target 4K and 8K resolution televisions at high frame rates, support for real-time ray tracing rendering, 3D spatial audio, variable refresh rates, the use of high-performance solid-state drives (SSD) as internal high-speed memory to make delivering game content much faster than reading from optical disc or standard hard drives, which can eliminate loading times and support in-game streaming. With features that were commonly standard in PCs, and the move to higher performance APUs, consoles in the ninth generation now have capabilities comparable to high-end personal computers, often making cross-platform development easier and more widely available than previously, further converging and blurring the line between video game consoles and personal computers. Microsoft released the fourth generation of Xbox with the Xbox Series X and Series S on November 10, 2020. The Series X has a base performance target of 60 frames per second at 4K resolution to be four times as powerful as the Xbox One X. One of Microsoft's goals with both units was to assure backward compatibility with all games supported by the Xbox One, including those original Xbox and Xbox 360 titles that are backward compatible with the Xbox One, allowing the Xbox Series X and Series S to support four generations of games. Sony's PlayStation 5 was released on November 12, 2020, and also is a similar performance boost over the PlayStation 4. The PlayStation 5 uses a custom SSD solution with much higher input/output rates that are almost comparable to RAM chip speeds, significantly improving rendering and data streaming speeds. The chip architecture is comparable to the PlayStation 4, allowing backwards compatible with most of the PlayStation 4 library while select games will need chip timing tweaking to make them compatible. In terms of handhelds, Sony has announced no further plans for handhelds after discontinuing the
