Quick Answers

So, is Ryzen 5 1400 better than Core i7-5775C?

It depends on what you want from the system. For gaming, Core i7-5775C is ahead with a 1.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen 5 1400 pulls ahead with 0.6% better PassMark. Ryzen 5 1400 also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

For streaming, content creation, and heavier multitasking, Ryzen 5 1400 is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Ryzen 5 1400 is the better buy right now. Ryzen 5 1400 comes in $197 cheaper on MSRP at $169 MSRP versus $366 MSRP, and it still gives you 0.6% better PassMark. The compromise is that Core i7-5775C is still the better pure gaming CPU with a 1.7% average FPS lead across 50 shared CPU game tests in our data. It is also 117.8% better value on MSRP (45.7 vs 21.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Ryzen 5 1400 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2015), 33.3% larger total L3 cache (8 MB vs 6 MB), and 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.
