Lenovo IdeaPad 15.3" Slim 3 Luna Grey
The AMD Ryzen 5 7535HS 6-core processor paired with 40GB DDR5 RAM and a 1TB NVMe SSD handles heavy multitasking, video editing, and 50-plus Chrome tabs without slowdown, while the 15.3-inch 300-nit anti-glare IPS display reduces eye strain during long sessions. The 1.85kg Luna Grey aluminum chassis and Wi-Fi 6 connectivity make it portable and ready for online gaming or streaming, though the integrated Radeon 660M graphics limit AAA gaming performance. Best for students and business users who need a responsive, large-memory laptop for coursework, productivity, and light creative work rather than demanding gaming.

The 30-Second Version
The IdeaPad Slim 3 is a productivity workhorse disguised as a gaming laptop. The 40GB RAM and 1TB SSD are standout specs, but the integrated Radeon 660M GPU is a weak spot that kills the gaming claims. Buy it for work and multitasking, not for gaming.

Performance
The Ryzen 5 7535HS handles everyday tasks without breaking a sweat. Six cores at up to 4.55GHz means smooth multitasking, and the 40GB of DDR5 RAM is one of the best configs we've seen in this class. You can run 50 Chrome tabs, a video call, and Photoshop at the same time without hitting a wall. The 1TB NVMe SSD is also a standout, landing in the 80th percentile for storage. Boot times are snappy and apps load fast. But the Radeon 660M is the elephant in the room. It's integrated graphics, and it shows. You'll get playable frame rates in older titles and esports games at low settings, but anything modern will struggle. The marketing says 'powerful gaming performance' and that's just not true. This is a productivity laptop with a gaming label slapped on it.

Prijs
Value & Pricing
Without a confirmed price, it's hard to judge value directly. But based on the specs, this is a machine that makes sense if you need lots of RAM and storage for productivity work. The 40GB of DDR5 is genuinely unusual at this tier, and the 1TB SSD is generous. If you can find it at a reasonable price, it's a solid deal for students and office workers. Just don't pay a gaming premium for it, because the gaming performance isn't there.

Overview
The Lenovo IdeaPad Slim 3 is a weird one. It's being marketed as a gaming laptop, but the Radeon 660M integrated graphics tell a very different story. What you actually get is a solid productivity machine with an absurd amount of RAM and storage for the price.
The Ryzen 5 7535HS is a capable 6-core chip, and 40GB of DDR5 is overkill in the best way. But that GPU sits in the 14th percentile of our database. This is a work laptop wearing a gamer's hoodie.
Common Questions
Q: Can this laptop actually run modern games?
Not well. The Radeon 660M is integrated graphics, so you'll get playable frame rates in older titles and esports games at low settings, but anything demanding will struggle. This is not a gaming laptop despite the marketing.
Q: Is 40GB of RAM overkill for everyday use?
For most people, yes. But if you run lots of browser tabs, virtual machines, or memory-hungry apps like Photoshop and Premiere, the extra headroom means you'll never have to think about closing things to free up memory.
Q: How is the port selection?
It's thin. You get one USB-C, HDMI, and Wi-Fi 6, but that's about it. If you need multiple USB-A ports or an SD card reader, you'll want a dongle or hub.
Who Should Skip This
Gamers should skip this one entirely. The Radeon 660M sits in the 14th percentile of our GPU database, which means it lags behind most dedicated graphics solutions. If you want to play modern titles at decent settings, look at the ASUS ROG Zephyrus G14 or HP OMEN Transcend 14 instead. Content creators who do heavy 3D rendering or 4K video work will also find the integrated graphics limiting.
Verdict
This is a good laptop for students, office workers, and anyone who needs serious multitasking power without spending a fortune. The 40GB of RAM and 1TB SSD are the real selling points. If you're a gamer or content creator who needs GPU horsepower, look elsewhere. The Radeon 660M just can't keep up with modern titles or heavy rendering workloads.
