Quick Answers

So, is Core i3-10300 better than Core i5-1145G7?

Yes. Core i3-10300 is the better all-around CPU here. It gives you a 8.9% average FPS lead across 50 shared CPU game tests in our data, 0.3% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i3-10300 is the better pick. According to our tests, it delivers 8.9% 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 i3-10300 is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads.

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

Core i3-10300 still makes the most sense overall. Core i3-10300 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 8.9% average FPS lead across 50 shared CPU game tests in our data.

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

Core i3-10300 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
