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

Celeron G3900TE

2015

Why buy it

✅Draws 35W instead of 80W, a 45W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics 510, while Pentium 1403 needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,850 vs 1,851).
❌Smaller total L3 cache (2 MB vs 5 MB).
❌Launch MSRP is still $42 MSRP, while Pentium 1403 mostly shows up through inconsistent older-market listings.

Pentium 1403

2012

Why buy it

✅+150% larger total L3 cache (5 MB vs 2 MB).

Trade-offs

❌128.6% higher power demand at 80W vs 35W.
❌No integrated graphics, while Celeron G3900TE can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium 1403 better than Celeron G3900TE?

Yes. Pentium 1403 is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data and 0.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium 1403 is the better pick. According to our tests, it delivers 0.2% 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, Pentium 1403 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 150% larger total L3 cache (5 MB vs 2 MB).

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

Pentium 1403 is still the much better call for a fresh build. Pentium 1403 comes in at an unclear MSRP at unclear MSRP versus $42 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Celeron G3900TE only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (44.0 vs 0.0 PassMark/$), 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 G3900TE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012). That makes it the safer long-term bet.
