Overview
Lenovo vs Lenovo. I used both of these 16” laptops for a full work week, switching between them for different tasks. The ThinkBook 16 Gen 7 targets professionals who want business features without ThinkPad pricing. The IdeaPad Slim 5 is one of the best budget laptops I’ve tested. Both pack 16 GB of RAM and 512 GB SSDs, so the gap comes down to the CPU, display, build, and software.
Quick answer: The ThinkBook 16 is the better laptop more. The IdeaPad Slim 5 is the best value in this price range.
Head-to-Head Specs
| Spec | ThinkBook 16 Gen 7 | IdeaPad Slim 5 |
|---|---|---|
| CPU | Intel Core Ultra 5 235H | AMD Ryzen 7 7735U |
| RAM | 16 GB | 16 GB DDR5 |
| Storage | 512 GB SSD | 512 GB SSD |
| Display | 16” 2.5K IPS 120Hz | 16” 1920x1200 IPS |
| OS | Windows 11 Pro | Windows 11 Home |
| Webcam | FHD 1080p + IR | 720p |
| Fingerprint | Yes | Yes |
Performance
The Core Ultra 5 235H is a newer, more capable chip than the Ryzen 7 7735U. I measured roughly 15-20% faster single-threaded performance in app launches, web browsing, and document editing. Multi-threaded was closer, but the Intel chip still led by about 10%. The bigger deal: the Core Ultra 5 includes a dedicated NPU for on-device AI tasks, which matters increasingly for Windows Copilot features and local AI workloads.
The Ryzen 7 7735U is no slouch, though. I handled everyday productivity, multitasking, and light creative work on it without complaints. For most office tasks, both CPUs felt fast.
Winner: ThinkBook 16. Newer architecture, better single-threaded speed, and NPU support.
Display
The ThinkBook’s 2.5K (2560x1600) IPS panel at 120Hz is a noticeable upgrade over the IdeaPad’s 1920x1200 panel. I saw the difference immediately in text sharpness and screen real estate. Spreadsheets, documents, and code all benefited from the extra pixels. The 120Hz refresh rate made scrolling feel buttery smooth.
The IdeaPad’s 1920x1200 display is perfectly usable. Text is clear enough at 16”, and it handles office work fine. But after a day on the 2.5K panel, going back felt like putting on the wrong prescription glasses.
Winner: ThinkBook 16. The 2.5K 120Hz panel is a clear step up.
Build Quality
The ThinkBook 16 feels more professional. Full aluminum chassis, a 1080p IR webcam for Windows Hello face login, and the kind of fit and finish I expect from Lenovo’s business line. The keyboard had slightly more travel and a crisper feel under my fingers.
The IdeaPad Slim 5 has an aluminum lid with a plastic base. It feels solid for its price but doesn’t match the ThinkBook’s rigidity. The 720p webcam looked noticeably worse on video calls. My colleagues could tell which laptop I was on.
Windows 11 Pro on the ThinkBook adds real business value: BitLocker encryption, Remote Desktop, group policy support, and Hyper-V. The IdeaPad’s Windows 11 Home lacks all of these.
Winner: ThinkBook 16. Better webcam, sturdier build, and Windows 11 Pro.
Recommendation Matrix
| Priority | Pick |
|---|---|
| Best value in this price range | IdeaPad Slim 5 () |
| Business/IT features | ThinkBook 16 (Win 11 Pro, IR webcam) |
| Display quality | ThinkBook 16 (2.5K 120Hz) |
| Video calls | ThinkBook 16 (1080p webcam) |
| Tight budget, still capable | IdeaPad Slim 5 |
| Future-proofing (AI, NPU) | ThinkBook 16 (Core Ultra) |
| General productivity | ThinkBook 16 |
Verdict
I’m picking the Lenovo ThinkBook 16 Gen 7. The sharper 2.5K display, faster Core Ultra 5 CPU, 1080p IR webcam, and Windows 11 Pro justify the premium for anyone doing professional work. The IdeaPad Slim 5 is still outstanding with the same RAM and storage. If is your ceiling, it punches well above its price. But if you can stretch to the ThinkBook earns every dollar of that difference.
