Core i9-9920X

2018

Why buy it

Trade-offs

❌Smaller total L3 cache (19 MB vs 64 MB).
❌Less compelling for workstation-style loads than EPYC 7501, which brings 32 cores / 64 threads.
❌Launch MSRP is still $1,189 MSRP, while EPYC 7501 mostly shows up through inconsistent older-market listings.

EPYC 7501

2017

Why buy it

✅+232.5% larger total L3 cache (64 MB vs 19 MB).
✅Better for workstations and heavier parallel workloads: 32 cores / 64 threads.
✅Draws 155W instead of 165W, a 10W reduction.

Trade-offs

❌Lower PassMark (24,925 vs 24,974).

Quick Answers

So, is Core i9-9920X better than EPYC 7501?

Not really, because they are built for different jobs. EPYC 7501 makes more sense for workstation-style multi-core throughput, while Core i9-9920X is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i9-9920X is the better pick. According to our tests, it delivers 0.0% 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, Core i9-9920X is the stronger fit. You are getting 0.2% better PassMark, backed by 12 cores and 24 threads.

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

Core i9-9920X is the better buy right now. Core i9-9920X comes in at an unclear MSRP at $1,189 MSRP versus unclear MSRP, and it still gives you a 0.0% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (21.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i9-9920X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2017) and more multi-core headroom with 12 cores / 24 threads instead of 32/64. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
