✅+100% larger total L3 cache (12 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.

Trade-offs

❌Lower PassMark (4,942 vs 5,016).
❌Launch MSRP is still $294 MSRP, while Processor N150 mostly shows up through inconsistent older-market listings.
❌Older platform position on LGA1366, while Processor N150 moves to FCBGA1264 and DDR5.

Quick Answers

So, is Xeon E5645 better than Processor N150?

Not really, because they are built for different jobs. Xeon E5645 makes more sense for workstation-style multi-core throughput, while Processor N150 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, Processor N150 is the stronger fit. You are getting 1.5% better PassMark, backed by 4 cores and 4 threads.

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

Xeon E5645 is the better buy right now. Xeon E5645 comes in at an unclear MSRP at $294 MSRP versus unclear MSRP, and it still gives you a 20.0% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Processor N150 is still stronger for heavier multi-core work with 1.5% better PassMark. It is also 100.0% better value on MSRP (16.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Processor N150 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2010), a healthier platform with FCBGA1264 and DDR5 instead of LGA1366, and more multi-core headroom with 4 cores / 4 threads instead of 6/12. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
