The HP Omen 15 is good for gaming and AI, while the Lenovo Flex 5 14 is only fair.
The HP Omen 15 is better suited for gaming and 3D tasks because it features a powerful Nvidia RTX 3070 GPU and a higher screen refresh rate of 144 Hz, compared to the Lenovo Flex 5 14's integrated AMD Vega 8 graphics and 60 Hz refresh rate. The Omen 15's GPU enables better handling of graphically intensive tasks and smoother visuals, while the higher refresh rate contributes to a more fluid gaming experience, making it more capable for those specific requirements than the Flex 5 14.

The HP Omen 15 and Lenovo Flex 5 14 are both good for engineering and design, though the HP Omen 15 is somewhat better.
The HP Omen 15 is well-suited for engineering and design due to its powerful AMD Ryzen CPU, ample RAM, high-end Nvidia RTX GPU, and good screen quality, but is less portable given its larger size and weight. Conversely, the Lenovo Flex 5 14 offers a newer AMD Ryzen CPU with integrated graphics suitable for less demanding tasks, a touch-enabled screen with a higher resolution for sharper imagery, in a more portable 2-in-1 form factor, though its graphics performance and screen color coverage are more modest.

The HP Omen 15 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, and content creation.
For general use, the HP Omen 15's superior resolution and brightness make it more suitable for daily tasks and multimedia consumption, while the Lenovo Flex 5 offers an adequate display that does a fair job for routine activities. In the field of engineering and design, the HP Omen 15's wider color gamuts ensure more precise color representation which is crucial for professionals working on detailed projects, but the Lenovo Flex 5 still provides acceptable color accuracy for less demanding design work. However, for gaming and 3D applications, the HP Omen 15 falls short due to its lower refresh rate, which can affect the smoothness and responsiveness of the visuals, a domain where neither laptop excels, as both prioritize other display attributes over high refresh rates.

"We consider around 1,260 Euros (~$1530) for a Ryzen 7 4800H, a GeForce RTX 2060, a 512 GB SSD and 16 GB dual-channel RAM to be a good offer that appeals to price-conscious gamers. Very high details are rarely a problem in the native resolution of 1,920 x 1,080. Buyers will also be spoiled with a top-notch battery life that even beats most other notebook classes. If HP now improves the speed of the WLAN module, the stability of the case and the repeatedly criticized picture quality, the competition will have to dress extra warmly."

"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."
