Pentium 1403 v2

2014

Why buy it

✅Draws 80W instead of 95W, a 15W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon X3350 across 50 shared CPU benchmark tests.
❌Lower PassMark (2,284 vs 2,291).
❌Smaller total L3 cache (6 MB vs 12 MB).
❌Launch MSRP is still $150 MSRP, while Xeon X3350 mostly shows up through inconsistent older-market listings.

Xeon X3350

2008

Why buy it

✅Better for gaming: +7.1% higher average FPS across 50 shared CPU benchmark tests.
✅+100% larger total L3 cache (12 MB vs 6 MB).

Trade-offs

❌18.8% higher power demand at 95W vs 80W.

Quick Answers

So, is Xeon X3350 better than Pentium 1403 v2?

Not really, because they are built for different jobs. Xeon X3350 makes more sense for workstation-style multi-core throughput, while Pentium 1403 v2 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon X3350 is the better pick. According to our tests, it delivers 7.1% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon X3350 is the stronger fit. You are getting 0.3% better PassMark. It also has the larger cache pool with 100% larger total L3 cache (12 MB vs 6 MB).

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

Xeon X3350 is still the much better call for a fresh build. Xeon X3350 comes in at an unclear MSRP at unclear MSRP versus $150 MSRP, and it still gives you a 7.1% average FPS lead across 50 shared CPU game tests in our data. Pentium 1403 v2 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 100.0% better value on paper (15.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1356.

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

Pentium 1403 v2 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2008). That makes it the safer long-term bet.
