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

Celeron G555

2012

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Sandy Bridge), while E1-2100 needs a discrete GPU.
✅Includes a boxed cooler (Intel Stock), unlike E1-2100.

Trade-offs

❌Lower PassMark (1,427 vs 1,435).
❌Launch MSRP is still $52 MSRP, while E1-2100 mostly shows up through inconsistent older-market listings.
❌622.2% higher power demand at 65W vs 9W.

E1-2100

2013

Why buy it

✅+0.6% higher PassMark.
✅Draws 9W instead of 65W, a 56W reduction.

Trade-offs

❌No integrated graphics, while Celeron G555 can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Celeron G555.

Quick Answers

So, is E1-2100 better than Celeron G555?

It depends on what you want from the system. For gaming, Celeron G555 is ahead with a 1.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, E1-2100 pulls ahead with 0.6% better PassMark.

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

For streaming, content creation, and heavier multitasking, E1-2100 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

E1-2100 is still the much better call for a fresh build. E1-2100 comes in at an unclear MSRP at unclear MSRP versus $52 MSRP, and it still gives you 0.6% better PassMark. Celeron G555 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (27.4 vs 0.0 PassMark/$), 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?

E1-2100 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.
