❌Less compelling for workstation-style loads than Opteron 3320 EE, which brings 4 cores / 4 threads.

Opteron 3320 EE

2012

Why buy it

✅+166.7% larger total L3 cache (8 MB vs 3 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

❌Lower PassMark (1,918 vs 1,943).
❌38.9% higher power demand at 25W vs 18W.
❌No integrated graphics, while Core i5-520UM can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-520UM better than Opteron 3320 EE?

Not really, because they are built for different jobs. Opteron 3320 EE makes more sense for workstation-style multi-core throughput, while Core i5-520UM 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 i5-520UM is the stronger fit. You are getting 1.3% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-520UM still makes the most sense overall. Core i5-520UM comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1.3% better PassMark.

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

Opteron 3320 EE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2010) and 166.7% larger total L3 cache (8 MB vs 3 MB). That makes it the safer long-term bet.
