Quick Answers

So, is EPYC 7763 better than EPYC 7663?

Yes. EPYC 7763 is the better overall CPU here. You are getting a 7.9% average FPS lead across 4 shared CPU game tests in our data, 2.8% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.

Which one is better for gaming?

If gaming is the priority, EPYC 7763 is the better pick here. According to our tests, it delivers 7.9% more average FPS across 4 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, EPYC 7763 is the better fit. You are getting 2.8% better PassMark, backed by 64 cores and 128 threads.

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

EPYC 7763 is still the faster CPU overall, but EPYC 7663 makes more sense if price matters more than absolute performance. EPYC 7763 is 23.9% more expensive on MSRP at $7,890 MSRP versus $6,366 MSRP, and it gives you a 7.9% average FPS lead across 4 shared CPU game tests in our data. EPYC 7663 is also 20.5% better value on MSRP (12.9 vs 10.7 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

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

EPYC 7763 is the more future-proof choice for 2026 and beyond. You are getting more multi-core headroom with 64 cores / 128 threads instead of 56/112. That extra cache should hold up really well in CPU-limited games and high-refresh builds.

Games Benchmarks

Paired with RTX 4090
