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

Atom E3827

2013

Why buy it

✅Draws 8W instead of 95W, a 87W 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 D 915 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Pentium D 915 across 49 shared CPU benchmark tests.
❌Lower PassMark (665 vs 705).

Pentium D 915

2006

Why buy it

✅Better for gaming: +5.8% higher average FPS across 49 shared CPU benchmark tests.

Trade-offs

❌Launch MSRP is still $74 MSRP, while Atom E3827 mostly shows up through inconsistent older-market listings.
❌1087.5% higher power demand at 95W vs 8W.
❌No integrated graphics, while Atom E3827 can still boot and troubleshoot without a discrete GPU.
