The HP 15’s Intel Core i3-1215U has two performance cores and four efficiency cores, delivering meaningfully faster single-threaded performance than the Aspire Go’s all-efficiency-core N305. In benchmarks consistently reported across review sites, the 1215U pulls ahead by 25–40% in single-core tasks. For everyday productivity, both are capable—but the HP handles heavier multitasking with less strain.

This is the Aspire Go’s biggest weakness. Its 128GB of Universal Flash Storage is phone-grade memory—slower than a true SSD and leaving only ~47GB free after Windows installation. The HP 15’s 256GB PCIe NVMe SSD is both faster and double the capacity. That said, the Aspire Go has an empty M.2 slot, so you can add your own NVMe drive for ~$25–$40.

Battery is where the Aspire Go 15 dominates. NotebookCheck measured 11 hours 33 minutes in their standardized WLAN test—the best in its comparison field. Multiple reviewers confirmed 10+ hours of real-world mixed use. The HP 15 manages a respectable 7.5–9 hours. If you need a laptop that lasts all day without hunting for outlets, the Aspire Go is the clear winner.

Both are plastic-bodied budget laptops, but the Aspire Go 15 surprised multiple reviewers with its premium-looking silver finish and comfortable, well-spaced keyboard. PCVarge called the keyboard “surprisingly spacious and comfy.” The HP 15’s keyboard is adequate but unremarkable.

The Aspire Go 15 edges ahead with a faster USB-C 3.2 Gen 2 port (10Gbps) with DisplayPort alt mode, plus HDMI 2.1 and Wi-Fi 6. The HP 15 counters with an SD card reader—handy for photographers—but its USB-C is only Gen 1, HDMI is older 1.4b, and base models ship with Wi-Fi 5.
