Celeron N4505

2021

Why buy it

✅Draws 10W instead of 120W, a 110W reduction.

Trade-offs

❌Lower PassMark (2,037 vs 2,039).
❌Smaller total L3 cache (4 MB vs 8 MB).
❌Less compelling for workstation-style loads than Xeon X5355, which brings 4 cores / 4 threads.

Xeon X5355

2006

Why buy it

✅+0.1% higher PassMark.
✅+100% larger total L3 cache (8 MB vs 4 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

❌Launch MSRP is still $4,491 MSRP, while Celeron N4505 mostly shows up through inconsistent older-market listings.
❌1100% higher power demand at 120W vs 10W.

Quick Answers

So, is Celeron N4505 better than Xeon X5355?

Not really, because they are built for different jobs. Xeon X5355 makes more sense for workstation-style multi-core throughput, while Celeron N4505 is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Xeon X5355 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

Celeron N4505 is still the faster CPU overall, but Xeon X5355 is easier to justify if budget matters more than peak performance. Celeron N4505 comes in at an unclear MSRP at unclear MSRP versus $4,491 MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon X5355 is still stronger for heavier multi-core work with 0.1% better PassMark. Xeon X5355 is also 100.0% better value on MSRP (0.5 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Celeron N4505 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2006). That makes it the safer long-term bet.
