ASUS Vivobook S 15.6" S5507QA-CB91-CB Silver 2026

A 99th percentile CPU and a gorgeous 3K OLED in a 0.89kg body for $670. Skip it if you need to game, buy it if you need to work.

The Snapdragon X Elite X1E 78 100 sits in the 99th percentile for CPU performance in our database, which is wild for a laptop this thin and light. Twelve cores at 3.4GHz chew through browser tabs, code compilation, and photo edits without breaking a sweat. The integrated Adreno GPU is the weak link, landing in the 28th percentile, so don't expect to game on this thing. But for the developer and productivity crowd, the CPU is genuinely best-in-class right now. The 16GB of LPDDR5X is fine for most workflows, though power users will feel the ceiling. The 512GB SSD is about average, which is a bit stingy for a machine this capable.

Against the Apple MacBook Pro M5, the Vivobook S 15 wins on price and display quality but loses on GPU performance and app compatibility. The Samsung Galaxy Book5 Pro is the closest Windows competitor, with a similar OLED panel but a less impressive CPU in our testing. The Microsoft Surface Laptop 7th Edition is the other ARM option worth considering, but its display doesn't match this ASUS. If you need real graphics power, the Lenovo Legion Pro 7i Gen 10 is the obvious choice, but it's twice the weight and a completely different class of machine.

At $670 refurbished, this is a steal. You're getting a 99th percentile CPU and a 92nd percentile display for less than half what a MacBook Pro M5 costs. The compromises, mainly the GPU and soldered RAM, are easier to swallow at this price. If you need a workhorse for coding, writing, or media consumption, this is one of the best value plays we've seen in months.

The ASUS Vivobook S 15 is one of those rare laptops that gets the fundamentals so right you almost forget it's running on ARM. That Snapdragon X Elite chip is an absolute monster for everyday work, and ASUS paired it with a 3K OLED panel that makes everything look stupidly good. At 0.89kg, this thing is lighter than most tablets with keyboards attached. The headline here is simple: flagship-level screen and CPU performance in a body you'll forget is in your bag.

If you're looking for a gaming laptop or anything that needs real GPU horsepower, this isn't it. The integrated Adreno graphics land in the 28th percentile, which means even older titles will struggle. Go get a Lenovo Legion Pro 7i Gen 10 or something with a discrete RTX card instead. Also skip this if you rely on niche x86 software that hasn't been ported to ARM yet, the compatibility headaches aren't worth it.

The ASUS Vivobook S 15 is the best ARM-based Windows laptop we've tested for the money. The Snapdragon X Elite delivers flagship CPU performance, the OLED display is stunning, and the 0.89kg weight makes it a joy to carry. The integrated GPU and soldered RAM are real limitations, but at $670 refurbished, those trade-offs are easy to justify. This is the laptop to beat for productivity-focused buyers who don't need discrete graphics.
