EPYC 7451

2017

Why buy it

✅+100% larger total L3 cache (64 MB vs 32 MB).
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 5 7600X across 45 shared CPU benchmark tests.
❌Lower PassMark (26,639 vs 28,325).
❌71.4% higher power demand at 180W vs 105W.
❌Older platform position on TR4 with DDR4, while Ryzen 5 7600X moves to AM5 and DDR5.
❌No integrated graphics, while Ryzen 5 7600X can still boot and troubleshoot without a discrete GPU.

Ryzen 5 7600X

2022

Why buy it

✅Better for gaming: +6.2% higher average FPS across 45 shared CPU benchmark tests.
✅Draws 105W instead of 180W, a 75W reduction.
✅Newer platform on AM5 with DDR5 support instead of TR4 and DDR4.
✅100+% more PCIe lanes (28 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with AMD Radeon Graphics (2-core), while EPYC 7451 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (32 MB vs 64 MB).
❌Less compelling for workstation-style loads than EPYC 7451, which brings 24 cores / 48 threads.
❌Launch MSRP is still $299 MSRP, while EPYC 7451 mostly shows up through inconsistent older-market listings.

Quick Answers

So, is Ryzen 5 7600X better than EPYC 7451?

Not in a simple one-size-fits-all way. EPYC 7451 makes more sense for workstation-style multi-core throughput, while Ryzen 5 7600X 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, Ryzen 5 7600X is the better pick here. According to our tests, it delivers 6.2% more average FPS across 45 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 5 7600X is the better fit. You are getting 6.3% better PassMark, backed by 6 cores and 12 threads.

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

Ryzen 5 7600X is the smarter buy today. Ryzen 5 7600X is at an unclear MSRP at $299 MSRP versus unclear MSRP, and it gives you a 6.2% average FPS lead across 45 shared CPU game tests in our data. It is also 100.0% better value on MSRP (94.7 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

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

Ryzen 5 7600X is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017), a healthier platform with AM5 and DDR5 instead of TR4, more multi-core headroom with 6 cores / 12 threads instead of 24/48, and AVX-512 support for heavier modern compute workloads. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

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.
