Quick Answers

So, is Ryzen 7 3700X better than Pentium Gold G6405T?
Yes. Ryzen 7 3700X is the better all-around CPU here. It gives you a 278.2% average FPS lead across 50 shared CPU game tests in our data and 624.7% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Ryzen 7 3700X is the better pick. According to our tests, it delivers 278.2% 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 7 3700X is the stronger fit. You are getting 624.7% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 700% larger total L3 cache (32 MB vs 4 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 7 3700X is the better buy right now. Ryzen 7 3700X comes in at an unclear MSRP at $329 MSRP versus unclear MSRP, and it still gives you a 278.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (68.2 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible LGA1200 + DDR4 setup, Pentium Gold G6405T 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?
Pentium Gold G6405T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2019). That makes it the safer long-term bet.
