Quick Answers

So, is Atom C3338 better than Pentium B950?

Yes. Atom C3338 is the better all-around CPU here. It gives you a 0.3% average FPS lead across 16 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, Atom C3338 is the better pick. According to our tests, it delivers 0.3% more average FPS across 16 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Atom C3338 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

Atom C3338 is still the much better call for a fresh build. Atom C3338 comes in at an unclear MSRP at unclear MSRP versus $134 MSRP, and it still gives you a 0.3% average FPS lead across 16 shared CPU game tests in our data. Pentium B950 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (7.6 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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

Atom C3338 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2011), 100% larger total L3 cache (4 MB vs 2 MB), and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
