Quick Answers

So, is Core i5-4670K better than Core i5-6600T?

Yes. Core i5-4670K is the better all-around CPU here. It gives you a 4.4% 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 i5-4670K is the better pick. According to our tests, it delivers 4.4% 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 i5-4670K is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 4 threads.

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

Core i5-4670K is still the much better call for a fresh build. Core i5-4670K comes in 54.0% more expensive on MSRP at $328 MSRP versus $213 MSRP, and it still gives you a 4.4% average FPS lead across 50 shared CPU game tests in our data. Core i5-6600T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 53.5% better value on paper (26.1 vs 17.0 PassMark/$), 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 i5-6600T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013). That makes it the safer long-term bet.
