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

Celeron G3900

2015

Why buy it

✅Draws 51W instead of 95W, a 44W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics 510, while Phenom II X4 B93 needs a discrete GPU.
✅Includes a boxed cooler (Intel Stock), unlike Phenom II X4 B93.

Trade-offs

❌Lower PassMark (2,155 vs 2,159).
❌Smaller total L3 cache (4 MB vs 6 MB).
❌Launch MSRP is still $42 MSRP, while Phenom II X4 B93 mostly shows up through inconsistent older-market listings.

Phenom II X4 B93

2009

Why buy it

✅+0.2% higher PassMark.
✅+50% larger total L3 cache (6 MB vs 4 MB).

Trade-offs

❌86.3% higher power demand at 95W vs 51W.
❌No integrated graphics, while Celeron G3900 can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Celeron G3900.

Quick Answers

So, is Phenom II X4 B93 better than Celeron G3900?

Yes. Phenom II X4 B93 is the better all-around CPU here. It gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data and 0.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Phenom II X4 B93 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).

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

Phenom II X4 B93 is still the much better call for a fresh build. Phenom II X4 B93 comes in at an unclear MSRP at unclear MSRP versus $42 MSRP, and it still gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data. Celeron G3900 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (51.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Celeron G3900 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009). That makes it the safer long-term bet.
