Quick Answers

So, is A6-6400K better than Core 2 Duo SU7300?

Yes. A6-6400K is the better all-around CPU here. It gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data, 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, A6-6400K is the better pick. According to our tests, it delivers 5.5% 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, A6-6400K is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

A6-6400K is the easy recommendation for a fresh desktop build. A6-6400K comes in at an unclear MSRP at unclear MSRP versus $289 MSRP, and it still gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo SU7300 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 5.5% in the shared gaming data.

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

A6-6400K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
