Overview
Two premium OLED convertibles, same Intel Core Ultra 7 258V processor, very different priorities. I used the Lenovo Yoga 9i 14 and Samsung Galaxy Book4 Pro 360 for the same daily mix of writing, browsing, video calls, and media for a week each. The Yoga bets on RAM, audio, and compactness. The Samsung bets on screen size and pen input.
Quick answer: The Yoga 9i wins on RAM, audio, and portability. The Galaxy Book4 Pro 360 wins on screen size and includes an S Pen. The 32 GB vs 16 GB RAM difference tips the balance.

Display
Samsung makes displays for a living, and it shows. The Galaxy Book4 Pro 360’s 16-inch AMOLED at 2880x1800 with 120Hz is gorgeous. Colors are oversaturated in the best possible way, with 120% DCI-P3 coverage. The extra screen real estate makes multitasking comfortable, and the 16:10 aspect ratio gives good vertical space for documents.
The Yoga 9i’s 14-inch 2.8K OLED at 90Hz is also excellent, with 100% DCI-P3 and perfect blacks. But it’s smaller and slower at 90Hz versus 120Hz. Side by side, the Samsung panel is more vibrant and the larger size is immediately noticeable.
That said, the Yoga’s 14-inch form factor makes it much more comfortable as an actual tablet. Holding a 16-inch laptop in tablet mode gets tiring fast.
Winner: Samsung Galaxy Book4 Pro 360. Bigger, brighter, and faster refresh rate.
Audio
Not even close. The Yoga 9i’s Bowers & Wilkins soundbar hinge is the best laptop speaker system I’ve tested. Full bass, wide stereo separation, room-filling volume. I stopped using external speakers during my testing period.
The Samsung’s speakers are fine. Clear enough for video calls, acceptable for casual YouTube watching. But they sound thin next to the Yoga. No bass presence, no warmth. If you care about audio from built-in speakers, the Yoga is in a different class.
Winner: Lenovo Yoga 9i 14. The B&W speakers are genuinely special.
Performance and RAM
Same processor, same integrated graphics. For everyday tasks, they feel identical. Where the difference shows up is RAM. The Yoga ships with 32 GB. The Samsung maxes out at 16 GB. Neither can be upgraded after purchase.
I noticed the 16 GB ceiling on the Samsung during heavier multitasking. Twenty Chrome tabs, a video call, Spotify, and a couple of Office documents open simultaneously. The system slowed slightly as it neared the limit. The Yoga handled the same workload without flinching. For longevity alone, 32 GB gives you years of headroom that 16 GB simply doesn’t.
Winner: Lenovo Yoga 9i 14. Double the RAM matters more every year.
Pen Input
Samsung includes the S Pen in the box with 4096 pressure levels and tilt detection. It’s a good pen for note-taking and light sketching. The downside: no storage garage. It magnetically sticks to the side and will fall off in a bag. I lost track of it twice.
The Yoga 9i supports Lenovo’s Precision Pen 2, but you buy it separately. The pen experience is similar once you have it, but the extra purchase stings.
Winner: Samsung Galaxy Book4 Pro 360. Included pen saves you the cost and hassle.
Recommendation Matrix
| Use Case | Pick |
|---|---|
| Best laptop speakers | Lenovo Yoga 9i 14 |
| Bigger screen for multitasking | Samsung Galaxy Book4 Pro 360 |
| Heavy multitasking (many tabs, apps) | Lenovo Yoga 9i 14 (32 GB RAM) |
| Note-taking with a pen out of the box | Samsung Galaxy Book4 Pro 360 |
| Lightest and most compact | Lenovo Yoga 9i 14 |
| Best tablet mode comfort | Lenovo Yoga 9i 14 |
| Future-proofing | Lenovo Yoga 9i 14 (32 GB RAM) |
| Best battery life | Samsung Galaxy Book4 Pro 360 |
Verdict
I’m picking the Lenovo Yoga 9i 14. The 32 GB of RAM is the deciding factor. In a world where neither laptop lets you upgrade memory after purchase, starting with double the capacity means the Yoga will stay capable years longer. The Bowers & Wilkins speakers are a genuine bonus that I missed every time I switched back to the Samsung. And at 3.1 lbs, it’s the more comfortable convertible to carry and use in tablet mode.
The Samsung Galaxy Book4 Pro 360 has the better display and the included S Pen is a real perk. If you prioritize screen size and pen input over RAM and audio, it’s an excellent 2-in-1. But that 16 GB ceiling is hard to overlook.
