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

3015Ce

2020

Why buy it

✅+100% larger total L3 cache (4 MB vs 2 MB).
✅Draws 1W instead of 2W, a 1W reduction.
✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon Graphics (2-Core), while Core 2 Duo T6400 needs a discrete GPU.

Trade-offs

❌Lower PassMark (2,099 vs 2,115).
❌Launch MSRP is still $150 MSRP, while Core 2 Duo T6400 mostly shows up through inconsistent older-market listings.

Core 2 Duo T6400

2009

Why buy it

✅+0.8% higher PassMark.

Trade-offs

❌Smaller total L3 cache (2 MB vs 4 MB).
❌100% higher power demand at 2W vs 1W.
❌No integrated graphics, while 3015Ce can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is 3015Ce better than Core 2 Duo T6400?

It depends on what you want from the system. For gaming, 3015Ce is ahead with a 0.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo T6400 pulls ahead with 0.8% better PassMark. 3015Ce also has the bigger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Core 2 Duo T6400 is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 2 threads.

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

3015Ce is the better buy right now. 3015Ce comes in at an unclear MSRP at $150 MSRP versus unclear MSRP, and it still gives you a 0.8% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core 2 Duo T6400 is still stronger for heavier multi-core work with 0.8% better PassMark. It is also 100.0% better value on MSRP (14.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

3015Ce makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2009) and 100% larger total L3 cache (4 MB vs 2 MB). That makes it the safer long-term bet.
