Quick Answers

So, is Core i7-10810U better than Core i7-6700?

It depends on what you want from the system. For gaming, Core i7-10810U is ahead with a 22.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-6700 pulls ahead with 0.8% better PassMark. Core i7-10810U also has the bigger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Core i7-6700 is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-10810U is still the much better call for a fresh build. Core i7-10810U comes in at an unclear MSRP at unclear MSRP versus $303 MSRP, and it still gives you a 22.8% average FPS lead across 50 shared CPU game tests in our data. Core i7-6700 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (26.6 vs 0.0 PassMark/$), 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 i7-10810U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2015) and 50% larger total L3 cache (12 MB vs 8 MB). That makes it the safer long-term bet.
