The Lenovo IdeaPad 3 15 (2021) and the Microsoft Surface Laptop 3 15 (2019) are both thin and light Windows laptops. The Surface Laptop 3 provides a better user experience for the most part because it has a sharper, brighter, and more color-accurate display, its keyboard feels better to type on, and its touchpad is larger and more responsive. The Surface Laptop 3 also has a better webcam and microphone for video calls. However, the IdeaPad 3 has a wider port selection, longer battery life, and its AMD Ryzen 5000 CPUs perform significantly better than the AMD Ryzen 3000 processors on the Surface Laptop 3.
The Lenovo IdeaPad 3 15 is a basic-looking laptop that shouldn't stick out in a professional environment. As it's a 15.6-inch device, it has enough room on the deck for a full-size keyboard with a Numpad on the right side. The exhaust vents are on the bottom near the back, while the speakers are near the front. It's available in four color schemes: Sand, Abyss Blue, Arctic Gray, and Galaxy Blue.
The Lenovo IdeaPad 3 has good build quality. The keyboard deck is a mix of plastic and metal, but the display and the bottom are mostly plastic. There aren't any obvious gaps in the construction, and it feels fairly solid overall, although the display flexes a lot.
The Lenovo IdeaPad 3's hinge is sub-par. It has a wide range and a good amount of resistance; however, the screen wobbles a bit when typing or moving around.
The Lenovo IdeaPad 3 15 is relatively thin and light for a 15.6-inch device, and its included power adapter is compact. Both fit easily into most bags.
The serviceability is good. To access the internals, you have to remove ten Philips screws and pry open the panel with a pick or prying tool. The model with 8GB of memory has 4GB soldered onto the motherboard and the other 4GB in the form of a user-replaceable SO-DIMM module. Lenovo's specifications indicate that you can upgrade the SO-DIMM module up to 8GB for a maximum of 12GB. The laptop comes with an M.2 2242 SSD, but the slot also supports longer M.2 2280 SSDs.
The Lenovo IdeaPad 3 is available with the following displays:
A 1080p resolution looks decently sharp on a 15.6-inch screen. You can see the individual pixels at normal viewing distances, but it's not too bad. Its 16:9 aspect ratio is great for media consumption since most videos are in the same format, although a 16:10 or 3:2 aspect ratio would have been better for productivity, as the increased vertical space lets you see more text when reading a document or website, meaning you won't have to scroll as much. For the best viewing experience, it's best to get a model with an IPS panel because TN panels usually have worse viewing angles and color reproduction.
The Lenovo IdeaPad 3 is only available with 60Hz displays. The IPS panel has a slow response time causing visible ghosting, which isn't ideal for viewing fast-moving content or gaming. The TN panel will likely perform similarly.
The contrast ratio is decent and within the typical range of most IPS panels. However, blacks still look gray in dim settings. The TN panel's contrast is likely worse, between 700 to 1000:1.
The display gets reasonably bright, just slightly above the advertised 300 cd/m². It's bright enough to combat glare in most settings, but not for outdoors in broad daylight. It gets very dim at the lowest brightness setting, which is great for dark room viewing, as it causes less eye strain. The TN panel is advertised to have a maximum brightness of 250 cd/m². If you need a laptop with a brighter display, check out the Acer Swift 3 14 (2022).
The Lenovo IdeaPad 3 15 has decent reflection handling. Its matte anti-reflective coating does a good job of diffusing bright lights and reducing their intensity. However, it's still possible to see some reflections even with the screen at maximum brightness.
The black uniformity is okay. The whole screen is more dark blue than black. There's some clouding here and there, as well as some backlight bleed along the top and bottom edges of the screen. The TN panel's uniformity will likely be much worse due to the TN panel's narrow viewing angles.
The Lenovo IdeaPad 3 has an okay horizontal viewing angle. The image looks noticeably darker from the sides, so you have to be close or directly in front of the screen to get the best accuracy. The TN panel will have a significantly worse viewing angle.
The Lenovo IdeaPad 3 has an okay vertical viewing angle. There's some color shift and darkening of the image when viewing from above or below. However, you still have a bit of play to tilt the screen before image accuracy degrades. The TN panel's viewing angle will be worse.
The display's overall accuracy is only decent. Most colors look inaccurate due to the panel's narrow color gamut; however, the white balance is outstanding, and the color temperature is very close to the standard 6500K target. The gamma doesn't quite follow the sRGB curve, causing dark scenes to appear darker than they should and bright scenes to be over-brightened.
The Lenovo IdeaPad 3 has a poor color gamut. It doesn't even have full coverage of the commonly-used sRGB color space, so most content looks washed out. It also has poor coverage of wider color spaces like Adobe RGB, DCI P3, and Rec. 2020. This display isn't suitable for any color-critical work or viewing HDR content. The TN panel will perform similarly.
The Lenovo IdeaPad 3 15 has a flicker-free backlight, which helps reduce eye strain. The line at maximum brightness isn't completely flat, but it seems to be just noise.
The Lenovo IdeaPad 3 has a decent keyboard. The size and key spacing are alright, though the Numpad feels a bit more cramped. The keys have a good amount of travel and provide tactile feedback, but they require a lot of force to actuate, which might cause fatigue over an extended period. They also feel unstable and somewhat cheap. You can adjust the backlight brightness or turn it off completely using FN and the spacebar. Unfortunately, the backlight only lights up around the keys, not through the key legends. Also, backlighting is an optional feature, so some models don't have it. If you want a similar laptop with a better keyboard, check out the Lenovo IdeaPad 5 15 (2021).
The Lenovo IdeaPad 3 15 has an okay touchpad. It's a bit small and doesn't feel smooth, and you can only click near the bottom of the touchpad, making dragging and dropping over long distances hard. Palm rejection is usually okay, but there are some instances where it would register a movement or tap. If you want a laptop with a better touchpad, check out the ASUS Vivobook 16 M1605 (2023).
The Lenovo IdeaPad 3 has decent speakers. They sound clear but slightly unnatural, with almost no bass whatsoever. There's very little dynamic compression at max volume, although these speakers don't get very loud, to begin with.
The webcam's video quality is decent. It captures some fine details like the writing on the bottle or the cards, but the whole image is overexposed, making colors appear washed out. The microphone sounds good overall; however, it's a bit quiet, and there's some static in the background. The privacy cover is only a physical switch and doesn't deactivate the camera at the software level, so it can still record audio when shut. Lastly, Lenovo's specifications indicate there's a Windows Hello-compatible IR camera to log in via facial recognition, but the feature isn't available when we tried activating it in Windows.
The Lenovo IdeaPad 3 has a decent port selection. There are two USB-A ports; the one on the left supports USB 3.2 Gen 1 standard (up to 5Gbps data transfer), while the one on the right supports only USB 2.0 standard (up to 480Mbps). The USB-C port also supports USB 3.2 Gen 1 data transfer rate. Unfortunately, you can't use the USB-C to charge the laptop or connect an external display.
The Lenovo IdeaPad 3 laptop's wireless adapter is a Realtek 8822CE. Lenovo advertises Wi-Fi 6 and Bluetooth 5.1 support on some models; however, they don't specify which wireless adapter those models use.
The Lenovo IdeaPad 3 is available with the following CPUs:
All three options are low-power CPUs designed for general productivity tasks like text processing, video playback, and web browsing. For most people with such a light workload, the Ryzen 3 5300U is likely more than powerful enough. If you have a heavier workload or need to run heavily multi-threaded applications, it's best to go with the AMD Ryzen 5 5500U or the Ryzen 7 5700U, as their increased core count and faster clock speeds will result in a smoother experience.
The Lenovo IdeaPad 3 is only available with integrated graphics. The AMD Ryzen 3 5300U CPU has Radeon RX Vega 6 graphics, the AMD Ryzen 5 5500U has Radeon RX Vega 7 graphics, and the AMD Ryzen 7 5700 has Radeon RX Vega 8 graphics. All three GPUs can only handle light tasks, not for demanding workloads like gaming or video editing. Although there's some difference in graphical performance between the three GPUs, the difference is extremely minimal.
You can configure the Lenovo IdeaPad 3 with 4, 8, 12, or 16GB of memory. It's best to get at least 8GB because 4GB is only barely enough for the operating system and may cause some slowdowns or stutters when multitasking.
The Lenovo IdeaPad 3 is available with 128GB, 256GB, 512GB, or 1TB of storage. You can also configure it with only a 5400 RPM 1TB hard drive or in combination with an SSD; however, it's best to avoid these models as the physical drive is significantly slower, and to make space for the drive, these models have a smaller 38Wh battery.
The Lenovo IdeaPad 3 scores reasonably well in the Geekbench 5 benchmarks. These scores indicate that the AMD Ryzen 3 5300U can provide a smooth experience in light workloads like text formatting, web browsing, and video playback. However, it'll struggle if you push it too hard with demanding tasks like video editing. The AMD Ryzen 5 5500U and Ryzen 7 5700U have better single-thread performance than the Ryzen 3 5300U, but it's mainly in multi-thread performance that you'll see the most gains, so they're better suited for people who perform heavy multitasking or use heavily multi-threaded applications. As for GPU computing tasks, none of the integrated graphics are powerful enough to handle such tasks. If you need to perform GPU-intensive tasks, it's best to get a laptop with a dedicated GPU.
The Lenovo IdeaPad 3 with an AMD Ryzen 3 5300U performs well in Cinebench R23's CPU rendering test. That said, if you do rendering work professionally, there are much faster CPUs on the market that are more suitable, like the Intel and AMD H-series processors and Apple's in-house ARM-based silicon. Upgrading to the AMD Ryzen 5 5500U or the Ryzen 7 5700U will give you better performance overall, but they still won't match the H-series CPUs found in mobile workstations and gaming laptops.
The Lenovo IdeaPad 3 laptop performs poorly in Blender. The CPU takes a long time to render the simple bmw27 scene, and it takes even longer with the integrated GPU. The AMD Ryzen 5 and 7 can complete this task faster, as Blender scales well with core count, but they'll likely still be too slow for professional workloads.
Like most systems with integrated graphics, the Lenovo IdeaPad 3 performs poorly in the Basemark GPU benchmark. This means it can only handle simple puzzle-like games, not graphically demanding AAA titles. The AMD Ryzen 5 5500U and the Ryzen 7 5700U will only perform slightly better, not enough to make much of a difference in most games.
The Lenovo IdeaPad 3's storage drive performance is excellent. Its fast read and write speeds mean the system can boot up, launch apps, and transfer large files quickly. Some models have a 2.5 inch physical hard drive as the primary or secondary drive. It's best to avoid models with a physical hard drive as the main drive because it's significantly slower than SSDs, and these variants have a smaller battery, which means you're trading battery life for storage. The speed of the SSD may vary depending on the size, as larger SSDs tend to perform better.
The Lenovo IdeaPad 3 15 has good battery life. You can get through a typical 8-hour day of light productivity with a bit of charge to spare. Video playback drains the battery faster; however, it still lasts long enough to get through a couple of movies and TV show episodes. Battery life is very short for gaming but much better than most gaming laptops with a dedicated GPU. The AMD Ryzen 5 5500U and Ryzen 7 5700U models will likely have shorter battery life due to their higher CPU core count and faster clock speeds. Models with a 2.5-inch hard drive or space to add one have a smaller 38Wh battery. Battery life can vary greatly depending on your usage.
Borderlands 3 runs terribly on the Lenovo IdeaPad 3 15. It's near unplayable even at the lowest graphical settings due to low frame rates and stutters. The AMD Ryzen 7 5700U can likely reach an average of 30fps with low settings, but you'll still see a lot of stutters.
Civilization VI runs poorly on the Lenovo IdeaPad 3 with an AMD Ryzen 3 5300U. It's a bit choppy at high graphical settings due to low frame rates, but it's much smoother if you turn down some settings. The turn time is okay and within the same ballpark as other AMD Ryzen 5000 and Intel 11th Gen. U-series CPUs. The AMD Ryzen 5 5500U and the AMD Ryzen 7 5700U will perform only slightly better.
The performance in CS:GO is middling. It doesn't quite reach 60fps at 1080p with high settings, and the frame rate frequently drops into the 20s, causing noticeable stutters. However, you can get much smoother gameplay if you turn the graphical settings down to minimum. The AMD Ryzen 5 5500U and the Ryzen 7 5700U will perform better, but not by much.
Shadow of the Tomb Raider runs awfully on the Lenovo IdeaPad 3 with an AMD Ryzen 3 5300U. The average frame rate doesn't even reach 30 fps at the lowest graphical settings, and there are lots of stutters. The AMD Ryzen 5 5500U and the AMD Ryzen 7 5700U models will only perform slightly better, not enough to make the game playable.
The Lenovo IdeaPad 3's keyboard deck is cool at idle and only gets slightly warm under load. However, the fans kick in pretty quickly, which explains the low temperature, and they get fairly loud. There's some space between the keyboard and the motherboard keeping the two parts separate, which also helps keep the keyboard cool.
The Lenovo IdeaPad 3's performance over time is outstanding. Neither the CPU nor GPU gets hot under load, and although there's a little bit of throttling on the CPU, the average amount of performance loss is extremely minimal and isn't noticeable. The AMD Ryzen 5 5500U or Ryzen 7 5700U will likely perform similarly.
The Lenovo IdeaPad 3 has a few pre-installed applications, including:
The Lenovo IdeaPad 3 has a fingerprint sensor built into the power button, allowing you to log into Windows quickly. The fingerprint sensor is an optional feature, so some models don't have it.
