Pentium G2120 vs PRO A6-8550B: Pros, Cons & Final Verdict

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

Pentium G2120

2012

Why buy it

✅Draws 55W instead of 65W, a 10W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Ivy Bridge), while PRO A6-8550B needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than PRO A6-8550B across 50 shared CPU benchmark tests.
❌Lower PassMark (1,876 vs 1,882).
❌Launch MSRP is still $86 MSRP, while PRO A6-8550B mostly shows up through inconsistent older-market listings.

PRO A6-8550B

2015

Why buy it

✅Better for gaming: +3.4% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

❌18.2% higher power demand at 65W vs 55W.
❌No integrated graphics, while Pentium G2120 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is PRO A6-8550B better than Pentium G2120?

Yes. PRO A6-8550B is the better all-around CPU here. It gives you a 3.4% average FPS lead across 50 shared CPU game tests in our data, 0.3% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, PRO A6-8550B is the better pick. According to our tests, it delivers 3.4% 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, PRO A6-8550B is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads.

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

PRO A6-8550B is still the much better call for a fresh build. PRO A6-8550B comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you a 3.4% average FPS lead across 50 shared CPU game tests in our data. Pentium G2120 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (21.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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

PRO A6-8550B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
