Quick Answers

So, is Celeron J4115 better than Core 2 Duo T7800?

It depends on what you want from the system. For gaming, Core 2 Duo T7800 is ahead with a 1.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron J4115 pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron J4115 is the stronger fit. You are getting 0.9% better PassMark, backed by 4 cores and 4 threads.

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

Celeron J4115 still makes the most sense overall. Celeron J4115 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.9% better PassMark.

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

Celeron J4115 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2007) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
