Celeron M 575

2008

Why buy it

✅Draws 1W instead of 25W, a 24W reduction.

Trade-offs

❌Lower PassMark (1,917 vs 1,918).
❌Less compelling for workstation-style loads than Opteron 3320 EE, which brings 4 cores / 4 threads.
❌Launch MSRP is still $86 MSRP, while Opteron 3320 EE mostly shows up through inconsistent older-market listings.

Opteron 3320 EE

2012

Why buy it

✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

❌2400% higher power demand at 25W vs 1W.

Quick Answers

So, is Opteron 3320 EE better than Celeron M 575?

Not really, because they are built for different jobs. Opteron 3320 EE makes more sense for workstation-style multi-core throughput, while Celeron M 575 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Opteron 3320 EE is the better pick. According to our tests, it delivers 1.5% 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, Opteron 3320 EE is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads.

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

Opteron 3320 EE is still the much better call for a fresh build. Opteron 3320 EE comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you a 1.5% average FPS lead across 50 shared CPU game tests in our data. Celeron M 575 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (22.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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 2008) and more multi-core headroom with 4 cores / 4 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
