Quick Answers

So, is Core 5 120U better than Core i5-1240P?

Yes. Core 5 120U is the better all-around CPU here. It gives you a 8.1% average FPS lead across 50 shared CPU game tests in our data, 0% 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 5 120U is the better pick. According to our tests, it delivers 8.1% 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 5 120U is the stronger fit. You are getting 0% better PassMark, backed by 10 cores and 12 threads.

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

Core 5 120U is the easy recommendation for a fresh desktop build. Core 5 120U comes in at an unclear MSRP at unclear MSRP versus $309 MSRP, and it still gives you a 8.1% average FPS lead across 50 shared CPU game tests in our data. Core i5-1240P 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 8.1% in the shared gaming data.

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

Core 5 120U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2022) and more multi-core headroom with 10 cores / 12 threads instead of 12/16. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
