Quick Answers

So, is Core i5-5350U better than Core i5-7Y54?

Yes. Core i5-5350U is the better all-around CPU here. It gives you a 3.2% average FPS lead across 50 shared CPU game tests in our data and 0.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-5350U is the better pick. According to our tests, it delivers 3.2% 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 i5-5350U is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-5350U is the easy recommendation for a fresh desktop build. Core i5-5350U comes in 12.1% more expensive on MSRP at $315 MSRP versus $281 MSRP, and it still gives you a 3.2% average FPS lead across 50 shared CPU game tests in our data. Core i5-7Y54 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 3.2% in the shared gaming data.

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

Core i5-7Y54 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2015) and 33.3% larger total L3 cache (4 MB vs 3 MB). That makes it the safer long-term bet.
