The Lenovo Flex 5 16 and Razer Book 13 are both only fair for gaming and AI.
The Lenovo Flex 5 16 and the Razer Book 13 are both equipped with integrated Iris Xe graphics and have modest screen refresh rates of 60 Hz, which are limitations for gaming and 3D applications that benefit from more powerful dedicated GPUs and higher refresh rates. While both have capable processors and quality IPS displays for general use, these components do not fully meet the demands of high-end gaming or professional 3D rendering tasks.

How the Lenovo Flex 5 16 and the Razer Book 13 compare to other laptops
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
"The Razer Book is like an XPS 13, but faster. The Book 13 combines the design philosophy and performance of a Blade Stealth with the 16:10 display of a Dell XPS 13 for an impressive piece of hardware. Office users who want something more stylish than the typical Dell, HP or Lenovo will certainly find themselves drawn to this Razer subnotebook. If your priorities are to have the best-looking and fastest 13-inch laptop in the office over auxiliary features, however, then the Book 13 proudly fulfills that niche."
