Quick Answers

So, is Xeon E5-2628L V3 better than Xeon E5-2689?

Yes. Xeon E5-2628L V3 is the better all-around CPU here. It gives you a 4.1% average FPS lead across 28 shared CPU game tests in our data, 0.3% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon E5-2628L V3 is the better pick. According to our tests, it delivers 4.1% more average FPS across 28 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon E5-2628L V3 is the stronger fit. You are getting 0.3% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 25% larger total L3 cache (25 MB vs 20 MB).

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

Xeon E5-2628L V3 is still the faster CPU overall, but Xeon E5-2689 is easier to justify if budget matters more than peak performance. Xeon E5-2628L V3 comes in at an unclear MSRP at unclear MSRP versus $1,800 MSRP, and it still gives you a 4.1% average FPS lead across 28 shared CPU game tests in our data. Xeon E5-2689 is also 100.0% better value on MSRP (5.5 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Xeon E5-2628L V3 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012), 25% larger total L3 cache (25 MB vs 20 MB), and more multi-core headroom with 10 cores / 20 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
