Athlon PRO 300U vs Pentium Gold G6400: Pros, Cons & Final Verdict

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

Athlon PRO 300U

2019

Why buy it

✅Draws 15W instead of 58W, a 43W reduction.
✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with AMD Radeon Vega 3, while Pentium Gold G6400 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Pentium Gold G6400 across 50 shared CPU benchmark tests.
❌Lower PassMark (4,080 vs 4,106).

Pentium Gold G6400

2020

Why buy it

✅Better for gaming: +4.1% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

❌286.7% higher power demand at 58W vs 15W.
❌No integrated graphics, while Athlon PRO 300U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium Gold G6400 better than Athlon PRO 300U?

Yes. Pentium Gold G6400 is the better all-around CPU here. It gives you a 4.1% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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, Pentium Gold G6400 is the better pick. According to our tests, it delivers 4.1% 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, Pentium Gold G6400 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Pentium Gold G6400 still makes the most sense overall. Pentium Gold G6400 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 4.1% average FPS lead across 50 shared CPU game tests in our data.

Which one is more future-proof for 2026 and beyond?

Pentium Gold G6400 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2019) and more multi-core headroom with 2 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
