Quick Answers

So, is Core i5-13600K better than Ryzen 5 PRO 7645?

Yes. Core i5-13600K is the better overall CPU here. You are getting a 1.7% average FPS lead across 4 shared CPU game tests in our data and 36.6% better PassMark, which makes it the stronger all-around choice.

Which one is better for gaming?

For gaming, the two CPUs are effectively a wash in the available data.

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

For streaming, content creation, and heavier multitasking, Core i5-13600K is the better fit. You are getting 36.6% better PassMark, backed by 14 cores and 20 threads.

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

Core i5-13600K is still the faster CPU overall, but Ryzen 5 PRO 7645 makes more sense if price matters more than absolute performance. Core i5-13600K is 43.7% more expensive on MSRP at $329 MSRP versus $229 MSRP, and it gives you a 1.7% average FPS lead across 4 shared CPU game tests in our data. Ryzen 5 PRO 7645 is also 5.2% better value on MSRP (120.4 vs 114.5 PassMark/$), which is why it is easier to justify for price-conscious builds on paper. That said, if you already own a compatible AM5 + DDR5 setup, Ryzen 5 PRO 7645 can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

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

Ryzen 5 PRO 7645 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022) and 33.3% larger total L3 cache (32 MB vs 24 MB). That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.
