Lenovo IdeaPad 14" 81X20002US 2021, Ryzen 7 4700U, 8GB, 512GB SSD, Graphite Gray

The Lenovo IdeaPad Flex 5 14ARE05 pairs an 8-core Ryzen 7 with a touchscreen 2-in-1 design, but 8GB of RAM and a dim 250-nit display hold it back. Prices range from USD 600 to USD 891, so shop carefully. It's a decent budget pick for students and casual users, but power users should look elsewhere.

The Ryzen 7 4700U is the star here. Eight cores and a 2.0GHz base clock give this thing real muscle for multitasking and CPU-heavy tasks like spreadsheets, coding, or running multiple browser tabs without choking. In our database, the CPU lands in the 39th percentile for this category, which sounds mediocre, but for a budget 2-in-1 it's actually a decent showing. You're getting a processor that can handle more than the rest of the machine can keep up with.

The problem is everything around it. 8GB of DDR4 RAM is the bottleneck. That's in the 13th percentile, and it means you'll feel the squeeze if you try to run a bunch of apps at once or keep 30 Chrome tabs open. The integrated Radeon Graphics are fine for video playback and light photo editing, but gaming performance is the weakest area by far, scoring just 11.6 out of 100 in our gaming category. Don't expect to play anything beyond older or very lightweight titles. The 512GB NVMe SSD is about average for storage, which is fine, but the port selection is also below average at the 35th percentile. You get three USB-A ports and one HDMI, but no USB-C, which feels dated in 2025.

Stacked against the competition, this IdeaPad Flex 5 is fighting an uphill battle. The Apple MacBook Pro M5 is in a completely different league on performance, battery life, and screen quality, but it also costs way more. The ASUS Zenbook UX3405CA and Microsoft Surface Laptop 7th Edition both offer better displays, more RAM options, and modern connectivity like USB-C and Wi-Fi 6. If you can stretch your budget, those are meaningfully better machines.

The HP OmniBook X Flip 14 is probably the closest direct competitor in terms of form factor and price. It's also a 2-in-1 with a touchscreen, but it tends to come with more RAM and a brighter panel. The MSI Creator A13V is aimed at creators and has a dedicated GPU, which makes it a better pick if you need any kind of graphics horsepower. The Lenovo's main advantage is that Ryzen 7 CPU at a lower price, but the 8GB RAM cap really limits how much that processor can shine.

Pricing on this thing is all over the place. We're seeing it listed between USD 600 and USD 891 across three US listings, which is a spread of USD 291. That's a huge gap for the same machine. If you're paying USD 600, this is a reasonable deal for a touchscreen 2-in-1 with an 8-core CPU and 512GB SSD. At USD 891, you're getting into territory where better options exist with more RAM, brighter screens, and modern ports.

Newegg has the best price in our database right now, so if you're set on this model, that's where you should look. But honestly, the value proposition depends entirely on what you pay. At the low end, the compromises make sense. At the high end, they don't. Shop around before you commit.

The Lenovo IdeaPad Flex 5 14ARE05 is a 2-in-1 that tries to do a little bit of everything without asking for a huge pile of cash. You get a Ryzen 7 4700U, a 14-inch 1080p touchscreen, and a 512GB NVMe SSD in a convertible chassis that weighs 1.77kg. On paper, that's a pretty tempting mix for students, remote workers, or anyone who wants a laptop that can occasionally pretend to be a tablet.

But here's the thing. The spec sheet tells two different stories. The CPU is an 8-core Ryzen 7, which sounds impressive until you realize it's paired with just 8GB of RAM and integrated Radeon Graphics. That RAM sits in the 13th percentile for this category, which is rough. And the screen, while 1080p and IPS, only hits 250 nits, putting it in the bottom third for brightness. So you're getting a capable processor in a body that holds it back in a few key ways.

Who is this actually for? Someone who needs a compact, touchscreen laptop for everyday tasks like web browsing, document editing, video calls, and light photo work. It's not a gaming machine, not a video editing workstation, and not a great choice if you like working outside in bright sunlight. But for basic productivity and media consumption, it's a solid budget-friendly option with a few compromises you'll want to know about before you buy.

Skip this if you need more than 8GB of RAM. That's the big one. Anyone who runs virtual machines, edits video, does heavy photo work, or just likes keeping 40 browser tabs open will hit the ceiling fast. The RAM is likely soldered, so you can't fix it later. Look at the ASUS Zenbook UX3405CA or Microsoft Surface Laptop 7th Edition instead, both of which offer 16GB configurations.

Also skip it if you care about screen quality. 250 nits is dim by modern standards, and the 32nd percentile screen ranking means you're getting a below-average panel. If you work in bright environments or just appreciate a vibrant display, the HP OmniBook X Flip 14 or even a used MacBook Air will serve you much better. And if you need USB-C for docking or modern accessories, this laptop's port selection will drive you nuts.

If you're a student or casual user who needs a compact touchscreen laptop for notes, web browsing, and streaming, and you can find this under USD 650, it's worth a look. The Ryzen 7 4700U gives you enough CPU headroom for everyday multitasking, and the 512GB SSD means you won't run out of space immediately. The backlit keyboard and 2-in-1 hinge are genuinely useful for late-night study sessions or couch browsing.

But if you're a power user, a gamer, or someone who works with lots of open applications, skip this. 8GB of RAM is a dealbreaker in 2025, and the dim 250-nit screen will frustrate you if you work near windows or outdoors. The lack of USB-C is also annoying if you have modern peripherals. For most people, spending a bit more on something with 16GB of RAM and a brighter display will pay off every single day.
