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 7800X3D

2023

Why buy it

  • Better for gaming: +41.1% higher average FPS across 4 shared CPU benchmark tests.
  • 100+% more PCIe lanes (28 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with AMD Radeon Graphics (2-core), while Ryzen 7 8840U needs a discrete GPU.

Trade-offs

  • Launch MSRP is still $449 MSRP, while Ryzen 7 8840U mostly shows up through inconsistent older-market listings.
  • 328.6% higher power demand at 120W vs 28W.

Ryzen 7 8840U

2023

Why buy it

  • Draws 28W instead of 120W, a 92W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Ryzen 7 7800X3D across 4 shared CPU benchmark tests.
  • Lower PassMark (23,415 vs 34,293).
  • No integrated graphics, while Ryzen 7 7800X3D can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Ryzen 7 7800X3D better than Ryzen 7 8840U?
Yes. Ryzen 7 7800X3D is the better overall CPU here. You are getting a 41.1% average FPS lead across 4 shared CPU game tests in our data, 46.5% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.
Which one is better for gaming?
If gaming is the priority, Ryzen 7 7800X3D is the better pick here. According to our tests, it delivers 41.1% more average FPS across 4 shared CPU game tests. It also has a big cache advantage at 96 MB vs 16 MB.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Ryzen 7 7800X3D is the better fit. You are getting 46.5% better PassMark, backed by 8 cores and 16 threads. It also carries the larger cache pool with 500% larger total L3 cache (96 MB vs 16 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 7 7800X3D is the smarter buy today. Ryzen 7 7800X3D is at an unclear MSRP at $449 MSRP versus unclear MSRP, and it gives you a 41.1% average FPS lead across 4 shared CPU game tests in our data. It is also 100.0% better value on MSRP (76.4 vs 0.0 PassMark/$), 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 7 7800X3D is the more future-proof choice for 2026 and beyond. You are getting 3D V-Cache and a much larger 96 MB L3 cache instead of 16 MB 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.
