See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Celeron G465

2012

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Sandy Bridge), while Core 2 Duo T9800 needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,185 vs 1,189).
❌Smaller total L3 cache (1.5 MB vs 6 MB).
❌Launch MSRP is still $70 MSRP, while Core 2 Duo T9800 mostly shows up through inconsistent older-market listings.
❌483.3% higher power demand at 35W vs 6W.

Core 2 Duo T9800

2009

Why buy it

✅+300% larger total L3 cache (6 MB vs 1.5 MB).
✅Draws 6W instead of 35W, a 29W reduction.

Trade-offs

❌No integrated graphics, while Celeron G465 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core 2 Duo T9800 better than Celeron G465?

Yes. Core 2 Duo T9800 is the better all-around CPU here. It gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data and 0.3% 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 T9800 is the better pick. According to our tests, it delivers 0.3% 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 T9800 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 300% larger total L3 cache (6 MB vs 1.5 MB).

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

Core 2 Duo T9800 is still the much better call for a fresh build. Core 2 Duo T9800 comes in at an unclear MSRP at unclear MSRP versus $70 MSRP, and it still gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data. Celeron G465 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (16.9 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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

Celeron G465 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2009). That makes it the safer long-term bet.
