Celeron G1820

2013

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Haswell), while Pentium G2100T needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (2 MB vs 3 MB).
❌Lower PassMark per dollar, at 15.4 vs 22.5 PassMark/$ ($110 MSRP vs $75 MSRP).
❌54.3% higher power demand at 54W vs 35W.

Pentium G2100T

2012

Why buy it

✅+50% larger total L3 cache (3 MB vs 2 MB).
✅Costs $35 less on MSRP ($75 MSRP vs $110 MSRP).
✅Delivers 46.2% more PassMark for each dollar spent, at 22.5 vs 15.4 PassMark/$ ($75 MSRP vs $110 MSRP).
✅Draws 35W instead of 54W, a 19W reduction.

Trade-offs

❌Lower PassMark (1,691 vs 1,696).

Quick Answers

So, is Celeron G1820 better than Pentium G2100T?

Yes. Celeron G1820 is the better all-around CPU here. It gives you a 1.1% 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, Celeron G1820 is the better pick. According to our tests, it delivers 1.1% 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, Celeron G1820 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?

Celeron G1820 is still the much better call for a fresh build. Celeron G1820 comes in 46.7% more expensive on MSRP at $110 MSRP versus $75 MSRP, and it still gives you a 1.1% average FPS lead across 50 shared CPU game tests in our data. Pentium G2100T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 46.2% better value on paper (22.5 vs 15.4 PassMark/$), 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?

Celeron G1820 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 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.
