    Quick Answers

    So, is Core i7-4870HQ better than Core i5-6600K?
    Yes. Core i7-4870HQ is the better all-around CPU here. It gives you a 8.2% average FPS lead across 50 shared CPU game tests in our data and 0.3% better PassMark, which is enough to make it the stronger overall pick.
    Which one is better for gaming?
    If gaming is the priority, Core i7-4870HQ is the better pick. According to our tests, it delivers 8.2% 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 i7-4870HQ is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Core i7-4870HQ is still the much better call for a fresh build. Core i7-4870HQ comes in at an unclear MSRP at unclear MSRP versus $242 MSRP, and it still gives you a 8.2% average FPS lead across 50 shared CPU game tests in our data. Core i5-6600K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (26.0 vs 0.0 PassMark/$), 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 i5-6600K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014). That makes it the safer long-term bet.
