Atom E3827

2013

Why buy it

✅Draws 8W instead of 10W, a 2W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while Pentium SU4100 needs a discrete GPU.

Trade-offs

❌Lower PassMark (665 vs 685).

Pentium SU4100

2009

Why buy it

✅+3% higher PassMark.

Trade-offs

❌Launch MSRP is still $289 MSRP, while Atom E3827 mostly shows up through inconsistent older-market listings.
❌25% higher power demand at 10W vs 8W.
❌No integrated graphics, while Atom E3827 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom E3827 better than Pentium SU4100?

It depends on what you want from the system. For gaming, Atom E3827 is ahead with a 0.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium SU4100 pulls ahead with 3% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium SU4100 is the stronger fit. You are getting 3% better PassMark, backed by 2 cores and 2 threads.

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

Atom E3827 is the easy recommendation for a fresh desktop build. Atom E3827 comes in at an unclear MSRP at unclear MSRP versus $289 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Pentium SU4100 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 0.1% in the shared gaming data.

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

Atom E3827 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009). That makes it the safer long-term bet.
