Trade-offs

❌Worse for gaming: lower average FPS than Xeon X5667 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (6 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon X5667, which brings 4 cores / 8 threads.
❌Launch MSRP is still $117 MSRP, while Xeon X5667 mostly shows up through inconsistent older-market listings.

Xeon X5667

2010

Why buy it

✅Better for gaming: +12.4% higher average FPS across 50 shared CPU benchmark tests.
✅+100% larger total L3 cache (12 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

❌Lower PassMark (4,697 vs 4,764).
❌171.4% higher power demand at 95W vs 35W.
❌No integrated graphics, while Core i5-6500T can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-6500T better than Xeon X5667?

Not really, because they are built for different jobs. Xeon X5667 makes more sense for workstation-style multi-core throughput, while Core i5-6500T is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Core i5-6500T is the stronger fit. You are getting 1.4% better PassMark, backed by 4 cores and 4 threads.

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

Core i5-6500T is the better buy right now. Core i5-6500T comes in at an unclear MSRP at $117 MSRP versus unclear MSRP, and it still gives you 1.4% better PassMark. The compromise is that Xeon X5667 is still the better pure gaming CPU with a 12.4% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (40.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i5-6500T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
