Yes. Core 2 Duo T8300 is the better all-around CPU here. It gives you a 2.6% average FPS lead across 50 shared CPU game tests in our data and 1.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core 2 Duo T8300 is the better pick. According to our tests, it delivers 2.6% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core 2 Duo T8300 is the stronger fit. You are getting 1.2% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

Core 2 Duo T8300 is still the much better call for a fresh build. Core 2 Duo T8300 comes in at an unclear MSRP at unclear MSRP versus $450 MSRP, and it still gives you a 2.6% average FPS lead across 50 shared CPU game tests in our data. Phenom X4 9450e only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (3.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM2+.

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

Phenom X4 9450e is the safer long-term CPU choice because it gives you more room to grow and a better platform outlook.
