Quick Answers

So, is Core i5-1135G7 better than Core i5-9400F?

It depends on what you want from the system. For gaming, Core i5-1135G7 is ahead with a 2.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-9400F pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-9400F is the stronger fit. You are getting 0.5% better PassMark, backed by 6 cores and 6 threads.

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

Core i5-1135G7 is still the faster CPU overall, but Core i5-9400F is easier to justify if budget matters more than peak performance. Core i5-1135G7 comes in at an unclear MSRP at unclear MSRP versus $182 MSRP, and it still gives you a 2.9% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-9400F is still stronger for heavier multi-core work with 0.5% better PassMark. Core i5-9400F is also 100.0% better value on MSRP (52.0 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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 a newer CPU generation (2020 vs 2019). That makes it the safer long-term bet.
