Quick Answers

So, is A10-7800 better than Core i7-875K?

Yes. A10-7800 is the better all-around CPU here. It gives you a 0.5% average FPS lead across 30 shared CPU game tests in our data, 1.1% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, A10-7800 is the better pick. According to our tests, it delivers 0.5% more average FPS across 30 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, A10-7800 is the stronger fit. You are getting 1.1% better PassMark, backed by 4 cores and 4 threads.

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

A10-7800 is still the much better call for a fresh build. A10-7800 comes in at an unclear MSRP at unclear MSRP versus $353 MSRP, and it still gives you a 0.5% average FPS lead across 30 shared CPU game tests in our data. Core i7-875K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (9.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.

Which one is more future-proof for 2026 and beyond?

A10-7800 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
