About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

EPYC 9845

2024

Why buy it

  • Massive L3 cache advantage with 320 MB vs 32 MB, which is a real win in CPU-limited gaming.
  • Better for workstations and heavier parallel workloads: 160 cores / 320 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 PassMark per dollar, at 11.3 vs 61.7 PassMark/$ ($13,564 MSRP vs $449 MSRP).
  • 271.4% higher power demand at 390W vs 105W.

Ryzen 7 5800X

2020

Why buy it

  • Costs $13,115 less on MSRP ($449 MSRP vs $13,564 MSRP).
  • Delivers 447.2% more PassMark for each dollar spent, at 61.7 vs 11.3 PassMark/$ ($449 MSRP vs $13,564 MSRP).
  • Draws 105W instead of 390W, a 285W reduction.

Trade-offs

  • No 3D V-Cache or similar L3 advantage, which matters in CPU-limited gaming (32 MB vs 320 MB).
  • Lower PassMark (27,712 vs 152,985).
  • Less compelling for workstation-style loads than EPYC 9845, which brings 160 cores / 320 threads and 128 PCIe lanes.
  • Older platform position on AM4 with DDR4, while EPYC 9845 moves to SP5 and DDR5.

Quick Answers

So, is EPYC 9845 better than Ryzen 7 5800X?
Not in a simple one-size-fits-all way. EPYC 9845 makes more sense for workstation-style multi-core throughput, while Ryzen 7 5800X 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 9845 is the better pick here. According to our tests, it delivers 0.9% more average FPS across 2 shared CPU game tests. It also has a big cache advantage at 320 MB vs 32 MB.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, EPYC 9845 is the better fit. You are getting 452.1% better PassMark, backed by 160 cores and 320 threads. It also carries the larger cache pool with 900% larger total L3 cache (320 MB vs 32 MB).
Which one is the smarter buy today, not just the cheaper CPU?
EPYC 9845 is still the faster CPU overall, but Ryzen 7 5800X makes more sense if price matters more than absolute performance. EPYC 9845 is 2920.9% more expensive on MSRP at $13,564 MSRP versus $449 MSRP, and it gives you a 0.9% average FPS lead across 2 shared CPU game tests in our data. Ryzen 7 5800X is also 447.2% better value on MSRP (61.7 vs 11.3 PassMark/$), 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 9845 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2020), a healthier platform with SP5 and DDR5 instead of AM4, 3D V-Cache and a much larger 320 MB L3 cache instead of 32 MB, and more multi-core headroom with 160 cores / 320 threads instead of 8/16. 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.
