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.

Ryzen 7 5800X

2020

Why buy it

  • Better for gaming: +6.7% higher average FPS across 2 shared CPU benchmark tests.
  • +100% larger total L3 cache (32 MB vs 16 MB).
  • 100+% more PCIe lanes (24 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Lower PassMark (27,712 vs 27,832).
  • Launch MSRP is still $449 MSRP, while Ryzen 7 7840H mostly shows up through inconsistent older-market listings.
  • 200% higher power demand at 105W vs 35W.
  • Older platform position on AM4 with DDR4, while Ryzen 7 7840H moves to FP8 and DDR5.

Ryzen 7 7840H

2023

Why buy it

Quick Answers

So, is Ryzen 7 7840H better than Ryzen 7 5800X?
It depends on what matters more to you. For gaming, Ryzen 7 5800X is ahead with a 6.7% average FPS lead across 2 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen 7 7840H pulls ahead with 0.4% better PassMark. Ryzen 7 5800X also has the bigger cache pool with 100% larger total L3 cache (32 MB vs 16 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Ryzen 7 7840H is the better fit. You are getting 0.4% better PassMark, backed by 8 cores and 16 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 7 7840H is still the faster CPU overall, but Ryzen 7 5800X makes more sense if price matters more than absolute performance. Ryzen 7 7840H is at an unclear MSRP at unclear MSRP versus $449 MSRP, and it gives you 0.4% better PassMark. The trade-off is that Ryzen 7 5800X is still the better pure gaming CPU with a 6.7% average FPS lead across 2 shared CPU game tests in our data. Ryzen 7 5800X is also 100.0% better value on MSRP (61.7 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.
Which one is more future-proof for 2026 and beyond?
Ryzen 7 7840H is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020), a healthier platform with FP8 and DDR5 instead of AM4, and more multi-core headroom with 8 cores / 16 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.
