For Mac users, Das offers a similar model, the Das Keyboard 4 Professional for Mac that fully supports macOS including custom keycaps and full function key and media control support. Whilst it is not the cheapest mechanical keyboard available, it will outlast your PC and potentially your next one as well. The root Edition is a variant of the popular and highly rated Das Keyboard 4 Professional and offers the same full-size keyboard layout, solid and robust construction and Cherry MX key switches. Das keyboard makes a wide range of solid and reliable mechanical keyboards with a focus on typing experience and build quality. The Das Keyboard 4 root Edition is one of my favourite mechanical keyboards.

Replaces the USB 3.0 hub of the Professional model with USB 2.0.

We hope that Luu gets to test some of the PS/2 keyboards so that we can get a better picture of latencies across brands and interfaces. USB being a polling-based protocol unlike PS/2, which is an interrupt based protocol, has inherent limitations on the number of data packets that can send interrupt requests and the acknowledgement (ACK) these packets receive from the USB controller.

Keyboard aficionados have long argued that PS/2 offers the least response time and supports N-key rollover better than USB. Luu plans to extend this study with a larger sample size and test the entire key press pipeline to better understand the factors contributing to high latency. One more limitation of this study is that all keyboards tested use the USB protocol. This study is a proof-of-concept to prove that many gaming and professional keyboards are actually not as fast compared to the conventional keyboards available. Practically speaking, it might not be possible for everyone to do latency testing.

Keyboard latency is an oft ignored aspect of building a PC.
