The Lenovo LOQ 15i offers a balance of performance and value, suitable for general use and engineering tasks with its capable processor and dedicated graphics card. It's also more affordable and has a longer battery life, making it a practical choice for everyday tasks and moderate gaming. However, its screen resolution is lower, and it's less portable due to its size and weight. On the other hand, the Razer Blade 15 is a high-end option with superior performance for gaming, 3D rendering, and machine learning, thanks to its more powerful graphics card and high refresh rate display. It's also more compact and has a higher quality build, with a better screen and color accuracy, which is great for creative professionals. But, it comes at a premium price and has a shorter battery life, which might not be as suitable for general productivity tasks throughout a full day without charging. Consider the Razer Blade 15 if you prioritize top-tier performance and portability, and are willing to pay more and charge more frequently. Opt for the Lenovo LOQ 15i if you want a more cost-effective solution with solid performance for everyday use and longer battery life. Give Feedback

PCMag
Mark Knapp | August 2023
"Even after a short time with the LOQ 15, you'll find it has a lot going for it, but ultimately it's just "good"—not quite a star. The performance is respectable for the hardware it’s running, but Lenovo had to make some design sacrifices to trim the price. One of the better aspects is the keyboard, making it one of the better low-cost gaming laptops to actually put your hands on."

Allen Ngo | March 2022
"The 2022 Blade 15 offers roughly 15 to 25 percent faster graphics performance and 20 percent faster CPU performance over last year's Core i7-11800H and RTX 3080 model. Thankfully, the system doesn't need to run noticeably louder or warmer to achieve faster results, but both power consumption and battery life take a hit. The higher consumption in particular appears to be a trend amongst many 12th gen Core laptops including the Schenker Uniwill Technology GM7AG8P or MSI Vector GP66 when compared to their previous generation counterparts. We're also glad to not see below-average CPU performance which was the case for the 10th gen Core i7-10875H model."
