Quick Answers

So, is Core i3-8145UE better than A8-5500B?

It depends on what you want from the system. For gaming, A8-5500B is ahead with a 5.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-8145UE pulls ahead with 1.4% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i3-8145UE is the stronger fit. You are getting 1.4% better PassMark, backed by 2 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i3-8145UE is the better buy right now. Core i3-8145UE comes in at an unclear MSRP at $281 MSRP versus unclear MSRP, and it still gives you 1.4% better PassMark. The compromise is that A8-5500B is still the better pure gaming CPU with a 5.5% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (14.3 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

Which one is more future-proof for 2026 and beyond?

Core i3-8145UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
