There is one 8mm heat pipe and two 6mm heat pipes to assist in heat dissipation. There is also a heat pipe on the back dedicated to memory cooling. Coupled with a large area of heat plates, the heat dissipation efficiency is quite impressive. Overall, the laptop weighs 2.4 kg, which seems satisfactory for a gaming laptop, but we would say that it is not very portable.
Nowadays, battery life is one of the most important factors for buyers to consider before purchasing any electronic device. This gaming laptop comes with an 80Wh battery, which is officially claimed to have a battery life of up to 8.1 hours. Another exciting thing is that the laptop comes with a 300W charger. It’s unclear why Lenovo uses such a powerful charger. Other competitors are offering 180W chargers in this segment.
It has also been reported that there are M.2 slots on both sides above the battery, with the metal cover on the left side removed, and only one M.2 port is available. The right side comes with a pre-installed SSD and wireless card. The SSD is an SN730 with sequential read speeds of 3312 MB/s, sequential write speeds of 2693 MB/s, 4K read speeds of 48.11 MB/s, and 4K write speeds of 151.7 MB/s. It has a 512GB SSD. The Wi-Fi card is an Intel AX200NGW, which supports Wi-Fi 6 networks, with a maximum speed of 2400 Mbps.
In addition, phase change silicone grease is pre-installed inside the metal cover at the corresponding location of the SSD for better heat conduction. It is also revealed to come with two 8GB DDR4 RAM pre-installed. The measured bandwidth is 47,116 MB/s, the write speed is 45,288 MB/s, the copy speed is 42,044 MB/s, and the latency is 93 ns. Both SSD and RAM can be upgraded.
In terms of performance, the Ryzen 7 5800H is very similar to the Ryzen 9 5900HX (which we have seen before). It is based on the Zen 3 architecture and adopts an 8-core, 16-thread design. It only differs in frequency. The base frequency, acceleration frequency, and thermal power consumption of 5900HX are slightly higher. Under the premise that the heat dissipation module is crucial, if there is no power consumption limit, the actual performance of the two processors will not differ too much.
The benchmark scores for the Ryzen 7 5800H are as follows:
- CPU-Z: the chipset has scored 591 points in the single-core test and 5887.4 in the multi-core test.
- CineBench R15: it has a single-core score of 232 CB and a multi-core score of 2149 CB.
- CineBench R20: it has a single-core score of 555 CB and a multi-core score of 5010 CB
- CineBench R23: it has a single-core score of 1373 CB and a multi-core score of 11736 CB.
- Chess: The relative performance multiple of chess is 69.55, and the score is 33385.
- wPrime: It took 31.2 seconds to run 32M data with a single core and 99.9 seconds to run 1024M data with a multi-core.
- X264 FHD Benchmark: Encode FHD X264 video, up to 61.01 frames per second.
- X265 FHD Benchmark: Encode X265 video can complete 63.57 frames per second.
Compared to the Ryzen 9 5900HX, the Ryzen 7 5800H on the Legion 5 Pro has almost the same performance, with single-core performance by less than 3% and multi-core performance by less than 6%. However, both processors are tested at different temperatures, and room temperature can have a special effect. The experience won’t make much difference.
Compared to several other processors, the Ryzen 7 5800H is the pinnacle without suspense. All models in the Lenovo Legion 2021 series support direct connection to a discrete graphics card. To switch between standalone display and blend mode, you must restart after selecting the desired mode. After the shutdown and restart, change the power supply circuit to change the output mode. In general, the hybrid output method is more flexible.
When a discrete graphics card is not required for rendering, use the lower-power integrated graphics card to handle all tasks, thereby reducing the average power consumption of the gaming notebook and extending its battery life. In discrete graphics mode, images are output directly to the screen from the discrete graphics card. In high-frame games, the integrated graphics performance doesn’t get worse, but the frame rate is limited.
The Lenovo Legion 5 Pro screen is also excellent, satisfying our quest for high refresh rates and high resolutions, and supports HDR displays, FreeSync, and many other features. It is ideal for laptops. The screen has 100% sRGB color gamut coverage. This color gamut is also well-suited for casual users who browse the web, watch videos, view images, and play games. It ensures accurate color mapping without distortion, such as oversaturation.
The display has a Gamma value of 2.2, which is also the most common choice. In default mode, the screen can reach 509.7 nits of brightness, which meets HDR400 certification requirements. The contrast ratio can reach 1190:1, which is lower than typical for IPS screens. The color temperature of the screen is around 6400 K. Usually, we adjust the color temperature and use this value as a standard.
The average color accuracy is 1.11, which meets the requirement of less than 2. At this value, the average person will not be able to see the color difference. In addition to its excellent quality, the Legion 5 Pro’s screen supports HDR and OD acceleration to eliminate smearing. The measurement is also noticeable, which can further enhance the gaming experience.
The Legion 5 Pro is arguably the most high-end, affordable, and well-stocked of all variants. Although the laptop is currently only available with RTX 3060 and RTX 3070, its performance has exceeded our expectations.
The Legion 5 Pro features a top-of-the-line screen with a 2.5K resolution, 165Hz refresh rate, HDR, FreeSync, and more, instantly surpassing the 1080P screens on the market. What’s more, you won’t pay extra for it on the Legion 5 Pro. It’s an excellent laptop for the price. This laptop is also quite affordable.
After all, a gaming laptop with the same performance has an absolute value for money compared to a desktop computer. The Lenovo Legion 5 Pro has an absolute performance advantage in the same configuration. The Legion 5 Pro is priced at $999, with prices varying in different regions.
