Quick Answers

So, is Atom E3826 better than Sempron 145?

It depends on what you want from the system. For gaming, Sempron 145 is ahead with 90.5% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Atom E3826 pulls ahead with 0.2% better PassMark.

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

For streaming, content creation, and heavier multitasking, Atom E3826 is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 2 threads.

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

Atom E3826 still makes the most sense overall. Atom E3826 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark.

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

Atom E3826 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2010) and more multi-core headroom with 2 cores / 2 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
