Quick Answers

So, is Ryzen 3 PRO 3300U better than Phenom II X6 1100T BE?

Yes. Ryzen 3 PRO 3300U is the better all-around CPU here. It gives you a 4.7% average FPS lead across 50 shared CPU game tests in our data, 1.5% 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, Ryzen 3 PRO 3300U is the better pick. According to our tests, it delivers 4.7% 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 PRO 3300U is the stronger fit. You are getting 1.5% better PassMark, backed by 4 cores and 4 threads.

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

Ryzen 3 PRO 3300U is still the much better call for a fresh build. Ryzen 3 PRO 3300U comes in at an unclear MSRP at unclear MSRP versus $265 MSRP, and it still gives you a 4.7% average FPS lead across 50 shared CPU game tests in our data. Phenom II X6 1100T BE only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (21.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

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

Ryzen 3 PRO 3300U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 6/6. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
