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

Celeron 3955U

2015

Why buy it

✅+0.9% higher PassMark.
✅Draws 15W instead of 35W, a 20W reduction.
✅100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 510, while Pentium G2020T needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (2 MB vs 3 MB).

Pentium G2020T

2013

Why buy it

✅+50% larger total L3 cache (3 MB vs 2 MB).

Trade-offs

❌Lower PassMark (1,430 vs 1,443).
❌Launch MSRP is still $64 MSRP, while Celeron 3955U mostly shows up through inconsistent older-market listings.
❌133.3% higher power demand at 35W vs 15W.
❌No integrated graphics, while Celeron 3955U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron 3955U better than Pentium G2020T?

It depends on what you want from the system. For gaming, Pentium G2020T is ahead with a 0.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 3955U pulls ahead with 0.9% better PassMark. Pentium G2020T also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron 3955U is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 2 threads.

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

Celeron 3955U is still the much better call for a fresh build. Celeron 3955U comes in at an unclear MSRP at unclear MSRP versus $64 MSRP, and it still gives you 0.9% better PassMark. Pentium G2020T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 100.0% better value on paper (22.3 vs 0.0 PassMark/$), 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?

Celeron 3955U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) 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.
