Quick Answers

So, is Core 2 Duo SU9300 better than Core Duo T2300?

It depends on what you want from the system. For gaming, Core Duo T2300 is ahead with a 0.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo SU9300 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, Core 2 Duo SU9300 is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo SU9300 still makes the most sense overall. Core 2 Duo SU9300 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?

Core 2 Duo SU9300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2006) 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.
