Quick Answers

So, is Core i5-7640X better than Core i7-5850EQ?
Yes. Core i5-7640X is the better all-around CPU here. It gives you a 5.4% average FPS lead across 50 shared CPU game tests in our data, 0.3% 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 i5-7640X is the better pick. According to our tests, it delivers 5.4% 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 i5-7640X is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-7640X is the better buy right now. Core i5-7640X comes in $186 cheaper on MSRP at $249 MSRP versus $435 MSRP, and it still gives you a 5.4% average FPS lead across 50 shared CPU game tests in our data. It is also 75.3% better value on MSRP (28.4 vs 16.2 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core i5-7640X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2015) and more multi-core headroom with 4 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
