Quick Answers

So, is EPYC 4245P better than Core i7-9700K?

Not really, because they are built for different jobs. EPYC 4245P makes more sense for workstation-style multi-core throughput, while Core i7-9700K is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, EPYC 4245P is the better pick. According to our tests, it delivers 1.3% 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, EPYC 4245P is the stronger fit. You are getting 116.3% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 166.7% larger total L3 cache (32 MB vs 12 MB).

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

EPYC 4245P is still the much better call for a fresh build. EPYC 4245P comes in at an unclear MSRP at unclear MSRP versus $385 MSRP, and it still gives you a 1.3% average FPS lead across 50 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (37.4 vs 0.0 PassMark/$), 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?

EPYC 4245P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2018), a healthier platform with AM5 and DDR5 instead of LGA1151, 166.7% larger total L3 cache (32 MB vs 12 MB), more multi-core headroom with 6 cores / 12 threads instead of 8/8, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
