Quick Answers

So, is Core i7-6820HK better than Core i7-6700T?

Yes. Core i7-6820HK is the better all-around CPU here. It gives you a 0.9% 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?

For gaming, this matchup is basically a tie in the data we have.

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

For streaming, content creation, and heavier multitasking, Core i7-6820HK is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-6820HK is still the much better call for a fresh build. Core i7-6820HK comes in 24.8% more expensive on MSRP at $378 MSRP versus $303 MSRP, and it still gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data. Core i7-6700T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 24.4% better value on paper (23.1 vs 18.6 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i7-6820HK makes more sense long term for 2026 and beyond. You are getting 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.
