Yes. Atom C3338 is the better all-around CPU here. It gives you a 0.7% average FPS lead across 50 shared CPU game tests in our data, 0.8% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

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 0.8% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

Atom C3338 still makes the most sense overall. Atom C3338 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.7% average FPS lead across 50 shared CPU game tests in our data.

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 2013), 33.3% larger total L3 cache (4 MB vs 3 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.
