Quick Answers

So, is Ryzen 3 3300U better than Xeon E3-1205 v6?

Not really, because they are built for different jobs. Xeon E3-1205 v6 makes more sense for workstation-style multi-core throughput, while Ryzen 3 3300U is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Ryzen 3 3300U 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, Ryzen 3 3300U is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads.

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

Ryzen 3 3300U still makes the most sense overall. Ryzen 3 3300U 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?

Ryzen 3 3300U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017) and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
