Quick Answers

So, is Core i7-6820HK better than Core i7-4790S?
It depends on what you want from the system. For gaming, Core i7-4790S is ahead with a 11.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-6820HK pulls ahead with 0.6% better PassMark.
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 0.6% 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 21.2% more expensive on MSRP at $378 MSRP versus $312 MSRP, and it still gives you 0.6% better PassMark. Core i7-4790S only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 20.5% better value on paper (22.3 vs 18.6 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.
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 a newer CPU generation (2015 vs 2014) and 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.
