Core i3-10305 vs Ryzen 5 3400G: Pros, Cons & Final Verdict

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

Core i3-10305

2021

Why buy it

  • +0.1% higher PassMark.
  • +100% larger total L3 cache (8 MB vs 4 MB).
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Ryzen 5 3400G needs a discrete GPU.
  • Includes a boxed cooler (Yes), unlike Ryzen 5 3400G.

Trade-offs

  • Worse for gaming: lower average FPS than Ryzen 5 3400G across 50 shared CPU benchmark tests.

Ryzen 5 3400G

2019

Why buy it

  • Better for gaming: +7.4% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

  • Lower PassMark (9,201 vs 9,210).
  • Smaller total L3 cache (4 MB vs 8 MB).
  • No integrated graphics, while Core i3-10305 can still boot and troubleshoot without a discrete GPU.
  • No boxed cooler included, unlike Core i3-10305.

Quick Answers

So, is Core i3-10305 better than Ryzen 5 3400G?
It depends on what you want from the system. For gaming, Ryzen 5 3400G is ahead with a 7.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-10305 pulls ahead with 0.1% better PassMark. Core i3-10305 also has the bigger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i3-10305 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-10305 is the better buy right now. Core i3-10305 comes in in basically the same MSRP band at $149 MSRP versus $149 MSRP, and it still gives you 0.1% better PassMark. The compromise is that Ryzen 5 3400G is still the better pure gaming CPU with a 7.4% average FPS lead across 50 shared CPU game tests in our data. It is also 0.1% better value on MSRP (61.8 vs 61.8 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible AM4 + DDR4 setup, Ryzen 5 3400G can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.
Which one is more future-proof for 2026 and beyond?
Core i3-10305 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2019), 100% larger total L3 cache (8 MB vs 4 MB), and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
