Quick Answers

So, is EPYC 7663 better than Core i7-9700K?
Not in a simple one-size-fits-all way. EPYC 7663 makes more sense for workstation-style multi-core throughput, while Core i7-9700K is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.
Which one is better for gaming?
If gaming is the priority, EPYC 7663 is the better pick here. According to our tests, it delivers 16.7% more average FPS across 3 shared CPU game tests. It also has a big cache advantage at 256 MB vs 12 MB.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, EPYC 7663 is the better fit. You are getting 470.4% better PassMark, backed by 56 cores and 112 threads. It also carries the larger cache pool with 2033.3% larger total L3 cache (256 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
EPYC 7663 is the smarter buy by a wide margin for a fresh build. EPYC 7663 is 1553.5% more expensive on MSRP at $6,366 MSRP versus $385 MSRP, and it gives you a 16.7% average FPS lead across 3 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 189.9% better value on paper (37.4 vs 12.9 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.
Which one is more future-proof for 2026 and beyond?
EPYC 7663 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2018), 3D V-Cache and a much larger 256 MB L3 cache instead of 12 MB, and more multi-core headroom with 56 cores / 112 threads instead of 8/8. That extra cache should hold up really well in CPU-limited games and high-refresh builds.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
