Quick Answers

So, is Core i7-9700K better than Athlon X4 845?

Yes. Core i7-9700K is the better all-around CPU here. It gives you a 176.0% average FPS lead across 50 shared CPU game tests in our data, 282.1% 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, Core i7-9700K is the better pick. According to our tests, it delivers 176.0% 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 i7-9700K is the stronger fit. You are getting 282.1% better PassMark, backed by 8 cores and 8 threads.

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

Core i7-9700K is still the much better call for a fresh build. Core i7-9700K comes in 450.0% more expensive on MSRP at $385 MSRP versus $70 MSRP, and it still gives you a 176.0% average FPS lead across 50 shared CPU game tests in our data. Athlon X4 845 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2016 platform. Even with 43.9% better value on paper (53.8 vs 37.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM2+.

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

Core i7-9700K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2016) and more multi-core headroom with 8 cores / 8 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
