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 midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."
