The Eluktronics Mech-15 G3R, with its premium price, offers top-notch performance for engineering, 3D rendering, and gaming due to its powerful processor and high-end graphics card, but it has moderate portability and battery life. On the other hand, the Lenovo Flex 5 16, more affordable, and with a touchscreen and a slightly larger screen, offers better battery life, lighter weight, and is very suitable for general use and tasks like drawing or casually consuming media, but it doesn’t match the Mech-15 G3R’s performance for demanding tasks or gaming.

The Eluktronics Mech-15 G3R has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, engineering and design, software development, and content creation.
The Eluktronics Mech-15 G3R offers a display with high resolution and brightness, making it pleasing for everyday tasks and detailed enough for engineering and design work, thanks to a color-accurate panel. However, its relatively lower refresh rate compared to gaming-centric laptops makes fast-paced visuals in gaming and 3D applications less smooth. Conversely, the Lenovo Flex 5 16 provides an adequate display for general computing and professional design with good brightness and acceptable color coverage but falls short for gaming and 3D due to a lower refresh rate and less emphasis on the fast panel response required by those applications.

Aaron Ritchie | September 2022
"Everything considered, the XMG Neo 15 (Mech-15 G3R) with RTX 3070 Ti is a great gaming performer. The combination of the Ti graphics card with the new Intel 12th gen CPU is enough to go toe-to-toe, and even slightly pull ahead of the RTX 3080 in most titles, though on games with Ray-Tracing enabled, particularly with graphics set to the maximum and on higher resolutions, the additional VRAM of the RTX 3080 makes a big impact, and the 8GB RTX 3070 Ti machine simply can’t compete, even with the more powerful processor."

"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."
