2011

Why buy it

Trade-offs

❌Worse for gaming: lower average FPS than Xeon L5638 across 50 shared CPU benchmark tests.
❌Lower PassMark (3,686 vs 3,707).
❌Smaller total L3 cache (8 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon L5638, which brings 6 cores / 12 threads.
❌Launch MSRP is still $165 MSRP, while Xeon L5638 mostly shows up through inconsistent older-market listings.

Xeon L5638

2010

Why buy it

✅Better for gaming: +9.9% higher average FPS across 50 shared CPU benchmark tests.
✅+50% larger total L3 cache (12 MB vs 8 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.
✅Draws 60W instead of 95W, a 35W reduction.

Quick Answers

So, is Xeon L5638 better than FX-6100?

Not really, because they are built for different jobs. Xeon L5638 makes more sense for workstation-style multi-core throughput, while FX-6100 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 L5638 is the better pick. According to our tests, it delivers 9.9% 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 L5638 is the stronger fit. You are getting 0.6% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Xeon L5638 is still the much better call for a fresh build. Xeon L5638 comes in at an unclear MSRP at unclear MSRP versus $165 MSRP, and it still gives you a 9.9% average FPS lead across 50 shared CPU game tests in our data. FX-6100 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (22.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3+.

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

FX-6100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010). That makes it the safer long-term bet.
