If you prioritize portability and longer battery life while handling general tasks or occasional creative work on a touchscreen, the Lenovo Flex 5 with its more affordable price may suit you well. However, the Razer Blade 17, despite being less portable and more expensive, offers superior performance for graphically intensive tasks like 3D rendering, machine learning, or gaming, thanks to a more powerful processor and high-end graphics card. The larger, higher-resolution screen of the Razer Blade will also benefit those tasks but at the cost of shorter battery life. Give Feedback

The Razer Blade 17 is very good for gaming and AI, while the Lenovo Flex 5 14 is only fair.
The Lenovo Flex 5 14's Vega 8 GPU and screen refresh rate of 60 Hz make it fair for gaming and 3D applications, while the Razer Blade 17, featuring a high-end Nvidia RTX 3080 Ti GPU and a faster 144 Hz refresh rate, provides excellent performance for such demanding tasks. Additionally, the Razer Blade 17's superior CPU and screen quality further contribute to its capability to handle intense gaming and 3D workloads compared to the Lenovo Flex 5 14.

The Razer Blade 17 is excellent for engineering and design, while the Lenovo Flex 5 14 is good.
The Razer Blade 17 offers superior performance for engineering and design through its more powerful CPU and GPU, twice the RAM, and a higher resolution screen than the Lenovo Flex 5 14, which makes it excellent for demanding tasks but less portable due to its larger size and weight. However, the Lenovo Flex 5 14's portability, touchscreen, and lower operating noise could make it a good fit for users who prioritize flexibility and quieter work environments.

The Razer Blade 17 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo Flex 5 14's screen might not have the high resolution or peak brightness that makes it stand out for general use, and it may lack the wide color gamut essential for professional engineering and design work. The Razer Blade 17's display, with its higher resolution and brightness, could be more suited for sharp and vibrant viewing in everyday tasks and detail-oriented work like engineering and design, thanks to its broader color range. However, due to a lower refresh rate, both the Lenovo and the Razer Blade might fall short for 3D applications and gaming, where smooth motion is crucial.

"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
"Our test configuration of the Blade 17 targets gamers and creative professionals. A Core i9-12900H processor, GeForce RTX 3080 Ti Laptop GPU (175 watts TGP after the BIOS update, 16 GB of VRAM), and 32 GB of working memory equip the laptop for video processing, rending, and 4k gaming at the highest level. In addition, a fast PCIe-4 SSD (1 TB) ensures short load and storage times. With the Blade 17 (Early 2022), Razer delivers a successful and powerful work device for creative professionals. But this also has its price."
