Quick Answers

So, is Core i5-8305G better than Atom x7835RE?

Yes. Core i5-8305G is the better all-around CPU here. It gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data and 0.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-8305G is the better pick. According to our tests, it delivers 1.4% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i5-8305G is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-8305G is the easy recommendation for a fresh desktop build. Core i5-8305G comes in 175.6% more expensive on MSRP at $350 MSRP versus $127 MSRP, and it still gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data. Atom x7835RE 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, especially when the gap is already 1.4% in the shared gaming data.

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

Atom x7835RE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2018) and a healthier platform with FCBGA1264 and DDR5 instead of FCBGA2270. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
