Quick Answers

So, is Sempron LE-1100 better than Celeron 2.40?

It depends on what you want from the system. For gaming, Celeron 2.40 is ahead with 26.3% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Sempron LE-1100 pulls ahead with 9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Sempron LE-1100 is the stronger fit. You are getting 9% better PassMark, backed by 1 cores and 1 threads.

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

Sempron LE-1100 is still the much better call for a fresh build. Sempron LE-1100 comes in at an unclear MSRP at unclear MSRP versus $69 MSRP, and it still gives you 9% better PassMark. Celeron 2.40 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2003 platform. Even with 100.0% better value on paper (5.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

Sempron LE-1100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2007 vs 2003) and more multi-core headroom with 1 cores / 1 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
