Quick Answers

So, is Xeon W3505 better than Pentium E6800?

Not really, because they are built for different jobs. Xeon W3505 makes more sense for workstation-style multi-core throughput, while Pentium E6800 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 W3505 is the better pick. According to our tests, it delivers 2.2% 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 W3505 is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 2 threads.

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

Xeon W3505 is still the much better call for a fresh build. Xeon W3505 comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you a 2.2% average FPS lead across 50 shared CPU game tests in our data. Pentium E6800 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (13.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Pentium E6800 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009). That makes it the safer long-term bet.
