It depends on what you want from the system. For gaming, Core i5-430UM is ahead with a 0.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 3755U pulls ahead with 25% better Geekbench multi-core. Core i5-430UM also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron 3755U is the stronger fit. You are getting 25% better Geekbench multi-core, backed by 2 cores and 2 threads.

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

Celeron 3755U still makes the most sense overall. Celeron 3755U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 25% better Geekbench multi-core.

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

Celeron 3755U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2010) and more multi-core headroom with 2 cores / 2 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
