Quick Answers

So, is Core i7-5775R better than Ryzen 3 2300X?

Yes. Core i7-5775R is the better all-around CPU here. It gives you a 7.4% average FPS lead across 50 shared CPU game tests in our data and 0.4% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-5775R is the better pick. According to our tests, it delivers 7.4% 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 i7-5775R is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).

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

Core i7-5775R is still the better call for a fresh build. Core i7-5775R comes in at an unclear MSRP at unclear MSRP versus $129 MSRP, and it still gives you a 7.4% average FPS lead across 50 shared CPU game tests in our data. Ryzen 3 2300X only looks stronger on raw value math because it is so cheap, but its absolute performance tier is too low to be the better recommendation now. At roughly 7,564 PassMark with 4 cores and 4 threads, it only really makes sense as a bare-minimum stopgap or a very constrained existing-platform upgrade.

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

Ryzen 3 2300X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2015). That makes it the safer long-term bet.
