Quick Answers

So, is Core i5-1135G7 better than Core i3-10300?

It depends on what you want from the system. For gaming, Core i3-10300 is ahead with a 15.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-1135G7 pulls ahead with 1.3% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-1135G7 is the stronger fit. You are getting 1.3% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-1135G7 still makes the most sense overall. Core i5-1135G7 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1.3% better PassMark.

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

Core i5-1135G7 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.
