Quick Answers

So, is Core i7-875K better than Core i3-6100TE?

Yes. Core i7-875K is the better all-around CPU here. It gives you a 11.5% average FPS lead across 50 shared CPU game tests in our data and 0.8% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-875K is the better pick. According to our tests, it delivers 11.5% 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 i7-875K is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

Core i7-875K is still the much better call for a fresh build. Core i7-875K comes in 41.2% more expensive on MSRP at $353 MSRP versus $250 MSRP, and it still gives you a 11.5% average FPS lead across 50 shared CPU game tests in our data. Core i3-6100TE only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 40.1% better value on paper (12.6 vs 9.0 PassMark/$), 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 i3-6100TE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2010). That makes it the safer long-term bet.
