Quick Answers

So, is Core i7-7820X better than Ryzen 7 PRO 2700X?

Yes. Core i7-7820X is the better all-around CPU here. It gives you a 2.4% average FPS lead across 50 shared CPU game tests in our data and 1.3% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-7820X is the better pick. According to our tests, it delivers 2.4% 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 i7-7820X is the stronger fit. You are getting 1.3% better PassMark, backed by 8 cores and 16 threads.

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

Core i7-7820X is still the faster CPU overall, but Ryzen 7 PRO 2700X is easier to justify if budget matters more than peak performance. Core i7-7820X comes in 82.1% more expensive on MSRP at $599 MSRP versus $329 MSRP, and it still gives you a 2.4% average FPS lead across 50 shared CPU game tests in our data. Ryzen 7 PRO 2700X is also 79.8% better value on MSRP (51.5 vs 28.7 PassMark/$), which is why it can still make sense for tighter-budget builds on paper. That said, if you already own a compatible AM4 + DDR4 setup, Ryzen 7 PRO 2700X can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

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

Ryzen 7 PRO 2700X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2017) and 45.5% larger total L3 cache (16 MB vs 11 MB). That makes it the safer long-term bet.
