Quick Answers

So, is Xeon E5420 better than Celeron B710?

Not really, because they are built for different jobs. Xeon E5420 makes more sense for workstation-style multi-core throughput, while Celeron B710 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 E5420 is the better pick. According to our tests, it delivers 3.5% 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 E5420 is the stronger fit. You are getting 349.5% better Geekbench multi-core, backed by 4 cores and 4 threads. It also has the larger cache pool with 700% larger total L3 cache (12 MB vs 1.5 MB).

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

Xeon E5420 is still the much better call for a fresh build. Xeon E5420 comes in 8288.4% more expensive on MSRP at $7,214 MSRP versus $86 MSRP, and it still gives you a 3.5% average FPS lead across 50 shared CPU game tests in our data. Celeron B710 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 8317.1% better value on paper (23.8 vs 0.3 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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

Celeron B710 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2007). That makes it the safer long-term bet.
