Pentium 3805U vs Ryzen 5 5600X: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Pentium 3805U

2015

Why buy it

  • Integrated graphics onboard with HD Graphics (Broadwell), while Ryzen 5 5600X needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Ryzen 5 5600X across 50 shared CPU benchmark tests.
  • Lower PassMark (1,196 vs 21,845).
  • Smaller total L3 cache (2 MB vs 32 MB).
  • 687.7% higher power demand at 512W vs 65W.

Ryzen 5 5600X

2020

Why buy it

  • Better for gaming: +606.4% higher average FPS across 50 shared CPU benchmark tests.
  • +1500% larger total L3 cache (32 MB vs 2 MB).
  • Draws 65W instead of 512W, a 447W reduction.
  • 100% more PCIe lanes (24 vs 12) for storage and expansion-heavy builds.

Trade-offs

  • Launch MSRP is still $299 MSRP, while Pentium 3805U mostly shows up through inconsistent older-market listings.
  • No integrated graphics, while Pentium 3805U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Ryzen 5 5600X better than Pentium 3805U?
Yes. Ryzen 5 5600X is the better all-around CPU here. It gives you a 606.4% average FPS lead across 50 shared CPU game tests in our data, 1726.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Ryzen 5 5600X is the better pick. According to our tests, it delivers 606.4% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Ryzen 5 5600X is the stronger fit. You are getting 1726.5% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 1500% larger total L3 cache (32 MB vs 2 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 5 5600X is the better buy right now. Ryzen 5 5600X comes in at an unclear MSRP at $299 MSRP versus unclear MSRP, and it still gives you a 606.4% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (73.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Ryzen 5 5600X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2015), 1500% larger total L3 cache (32 MB vs 2 MB), and more multi-core headroom with 6 cores / 12 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
