Quick Answers

So, is FX-8320E better than Xeon E5-2420?

Not really, because they are built for different jobs. Xeon E5-2420 makes more sense for workstation-style multi-core throughput, while FX-8320E 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 E5-2420 is the stronger fit. You are getting 1% better PassMark, backed by 6 cores and 12 threads.

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

FX-8320E is the better buy right now. FX-8320E comes in at an unclear MSRP at $147 MSRP versus unclear MSRP, and it still gives you a 8.5% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E5-2420 is still stronger for heavier multi-core work with 1% better PassMark. It is also 100.0% better value on MSRP (33.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

FX-8320E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012). That makes it the safer long-term bet.
