Ryzen 5 240 vs Ryzen 7 3800X: Pros, Cons & Final Verdict

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

Ryzen 5 240

2025

Why buy it

  • +0.7% higher PassMark.
  • Draws 45W instead of 105W, a 60W reduction.
  • Newer platform on FP8 with DDR5 support instead of AM4 and DDR4.

Trade-offs

  • Worse for gaming: lower average FPS than Ryzen 7 3800X across 50 shared CPU benchmark tests.
  • Smaller total L3 cache (16 MB vs 32 MB).

Ryzen 7 3800X

2019

Why buy it

  • Better for gaming: +10.0% higher average FPS across 50 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 (23,008 vs 23,167).
  • Launch MSRP is still $399 MSRP, while Ryzen 5 240 mostly shows up through inconsistent older-market listings.
  • 133.3% higher power demand at 105W vs 45W.
  • Older platform position on AM4 with DDR4, while Ryzen 5 240 moves to FP8 and DDR5.

Quick Answers

So, is Ryzen 5 240 better than Ryzen 7 3800X?
It depends on what you want from the system. For gaming, Ryzen 7 3800X is ahead with a 10.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen 5 240 pulls ahead with 0.7% better PassMark. Ryzen 7 3800X 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 5 240 is the stronger fit. You are getting 0.7% better PassMark, backed by 6 cores and 12 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 5 240 is still the faster CPU overall, but Ryzen 7 3800X is easier to justify if budget matters more than peak performance. Ryzen 5 240 comes in at an unclear MSRP at unclear MSRP versus $399 MSRP, and it still gives you 0.7% better PassMark. The compromise is that Ryzen 7 3800X is still the better pure gaming CPU with a 10.0% average FPS lead across 50 shared CPU game tests in our data. Ryzen 7 3800X is also 100.0% better value on MSRP (57.7 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
Ryzen 5 240 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2019), a healthier platform with FP8 and DDR5 instead of AM4, and more multi-core headroom with 6 cores / 12 threads instead of 8/16. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
