Quick Answers

So, is Atom C3758 better than Core i3-1115GRE?

Yes. Atom C3758 is the better all-around CPU here. It gives you a 22.7% average FPS lead across 50 shared CPU game tests in our data, 7.5% better Geekbench multi-core, and 0.6% higher PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Atom C3758 is the better pick. According to our tests, it delivers 22.7% 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, Atom C3758 is the stronger fit. You are getting 7.5% better Geekbench multi-core, backed by 8 cores and 8 threads. It also has the larger cache pool with 166.7% larger total L3 cache (16 MB vs 6 MB).

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

Atom C3758 is the easy recommendation for a fresh desktop build. Atom C3758 comes in at an unclear MSRP at unclear MSRP versus $338 MSRP, and it still gives you a 22.7% average FPS lead across 50 shared CPU game tests in our data. Core i3-1115GRE 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 22.7% in the shared gaming data.

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

Core i3-1115GRE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2017). That makes it the safer long-term bet.
