Athlon X4 950 vs Xeon E5620: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Athlon X4 950

2017

Why buy it

✅Draws 65W instead of 80W, a 15W reduction.
✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.
✅Includes a boxed cooler (Yes), unlike Xeon E5620.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5620 across 50 shared CPU benchmark tests.
❌Lower PassMark (3,576 vs 3,621).
❌Less compelling for workstation-style loads than Xeon E5620, which brings 4 cores / 8 threads.
❌Launch MSRP is still $58 MSRP, while Xeon E5620 mostly shows up through inconsistent older-market listings.

Xeon E5620

2010

Why buy it

✅Better for gaming: +8.4% higher average FPS across 50 shared CPU benchmark tests.
✅Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

❌23.1% higher power demand at 80W vs 65W.
❌No boxed cooler included, unlike Athlon X4 950.

Quick Answers

So, is Xeon E5620 better than Athlon X4 950?

Not really, because they are built for different jobs. Xeon E5620 makes more sense for workstation-style multi-core throughput, while Athlon X4 950 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 E5620 is the better pick. According to our tests, it delivers 8.4% 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 E5620 is the stronger fit. You are getting 1.3% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E5620 is still the better call for a fresh build. Xeon E5620 comes in at an unclear MSRP at unclear MSRP versus $58 MSRP, and it still gives you a 8.4% average FPS lead across 50 shared CPU game tests in our data. Athlon X4 950 only looks stronger on raw value math because it is so cheap, but its absolute performance tier is too low to be the better recommendation now. At roughly 3,576 PassMark with 4 cores and 4 threads, it only really makes sense as a bare-minimum stopgap or a very constrained existing-platform upgrade.

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

Athlon X4 950 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2010). That makes it the safer long-term bet.
