Quick Answers

So, is Atom x7433RE better than Core i3-8145UE?

It depends on what you want from the system. For gaming, Core i3-8145UE is ahead with 14.7% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Atom x7433RE pulls ahead with 0.7% better PassMark. Atom x7433RE also has the bigger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).

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

For streaming, content creation, and heavier multitasking, Atom x7433RE is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).

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

Atom x7433RE is the easy recommendation for a fresh desktop build. Atom x7433RE comes in at an unclear MSRP at unclear MSRP versus $281 MSRP, and it still gives you 0.7% better PassMark. Core i3-8145UE only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Atom x7433RE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2018), a healthier platform with FCBGA1264 and DDR5 instead of FCBGA1528, 50% larger total L3 cache (6 MB vs 4 MB), and more multi-core headroom with 4 cores / 4 threads instead of 2/4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
