Celeron B800 vs Opteron 3320 EE: Pros, Cons & Final Verdict

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

Celeron B800

2011

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Sandy Bridge), while Opteron 3320 EE needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,910 vs 1,918).
❌Smaller total L3 cache (2 MB vs 8 MB).
❌Less compelling for workstation-style loads than Opteron 3320 EE, which brings 4 cores / 4 threads.
❌Launch MSRP is still $80 MSRP, while Opteron 3320 EE mostly shows up through inconsistent older-market listings.
❌40% higher power demand at 35W vs 25W.

Opteron 3320 EE

2012

Why buy it

✅+300% larger total L3 cache (8 MB vs 2 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.
✅Draws 25W instead of 35W, a 10W reduction.

Trade-offs

❌No integrated graphics, while Celeron B800 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Opteron 3320 EE better than Celeron B800?

Not really, because they are built for different jobs. Opteron 3320 EE makes more sense for workstation-style multi-core throughput, while Celeron B800 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 0.7% 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 0.4% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 300% larger total L3 cache (8 MB vs 2 MB).

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 $80 MSRP, and it still gives you a 0.7% average FPS lead across 50 shared CPU game tests in our data. Celeron B800 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (23.9 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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 2011), 300% larger total L3 cache (8 MB vs 2 MB), and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
