✅Better for workstations and heavier parallel workloads: 48 cores / 96 threads, plus 128 PCIe lanes vs 24.
✅Newer platform on SP5 with DDR5 support instead of AM4 and DDR4.
✅433.3% more PCIe lanes (128 vs 24) for storage and expansion-heavy builds.

Trade-offs

❌Lower Geekbench multi-core (1,898 vs 9,715).
❌Lower PassMark per dollar, at 24.3 vs 89.0 PassMark/$ ($4,819 MSRP vs $299 MSRP).
❌361.5% higher power demand at 300W vs 65W.

Ryzen 7 5700X

2022

Why buy it

✅+411.9% higher Geekbench multi-core.
✅Costs $4,520 less on MSRP ($299 MSRP vs $4,819 MSRP).
✅Delivers 266.8% more PassMark for each dollar spent, at 89.0 vs 24.3 PassMark/$ ($299 MSRP vs $4,819 MSRP).
✅Draws 65W instead of 300W, a 235W reduction.

Trade-offs

❌No 3D V-Cache or similar L3 advantage, which matters in CPU-limited gaming (32 MB vs 256 MB).
❌Less compelling for workstation-style loads than EPYC 9455P, which brings 48 cores / 96 threads and 128 PCIe lanes.
❌Older platform position on AM4 with DDR4, while EPYC 9455P moves to SP5 and DDR5.

Quick Answers

So, is Ryzen 7 5700X better than EPYC 9455P?

Not in a simple one-size-fits-all way. EPYC 9455P makes more sense for workstation-style multi-core throughput, while Ryzen 7 5700X is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

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

For streaming, content creation, and heavier multitasking, Ryzen 7 5700X is the better fit. You are getting 411.9% better Geekbench multi-core, backed by 8 cores and 16 threads.

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

Ryzen 7 5700X is the smarter buy today. Ryzen 7 5700X is $4,520 cheaper on MSRP at $299 MSRP versus $4,819 MSRP, and it gives you 411.9% better Geekbench multi-core. The trade-off is that EPYC 9455P is still the better pure gaming CPU with a 0.9% average FPS lead across 50 shared CPU game tests in our data. It is also 266.8% better value on MSRP (89.0 vs 24.3 PassMark/$), 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?

EPYC 9455P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2022), a healthier platform with SP5 and DDR5 instead of AM4, and 3D V-Cache and a much larger 256 MB L3 cache instead of 32 MB. 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.
