Quick Answers

So, is Core i5-13420H better than Core i7-7820X?

Yes. Core i5-13420H is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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 i5-13420H is the better pick. According to our tests, it delivers 0.2% 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 i5-13420H is the stronger fit. You are getting 0.2% better PassMark, backed by 8 cores and 12 threads.

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

Core i5-13420H is still the much better call for a fresh build. Core i5-13420H comes in at an unclear MSRP at unclear MSRP versus $599 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Core i7-7820X only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (28.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2066.

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

Core i5-13420H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017), a healthier platform with FCBGA1744 and DDR5 instead of LGA2066, and more multi-core headroom with 8 cores / 12 threads instead of 8/16. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
