Quick Answers

So, is Xeon E5-2628L v4 better than Xeon E5-2640 v3?

It depends on what you want from the system. For gaming, Xeon E5-2640 v3 is ahead with a 2.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon E5-2628L v4 pulls ahead with 0.2% better PassMark. Xeon E5-2628L v4 also has the bigger cache pool with 50% larger total L3 cache (30 MB vs 20 MB).

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

For streaming, content creation, and heavier multitasking, Xeon E5-2628L v4 is the stronger fit. You are getting 0.2% better PassMark, backed by 12 cores and 24 threads. It also has the larger cache pool with 50% larger total L3 cache (30 MB vs 20 MB).

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

Xeon E5-2628L v4 is still the faster CPU overall, but Xeon E5-2640 v3 is easier to justify if budget matters more than peak performance. Xeon E5-2628L v4 comes in at an unclear MSRP at unclear MSRP versus $939 MSRP, and it still gives you 0.2% better PassMark. The compromise is that Xeon E5-2640 v3 is still the better pure gaming CPU with a 2.4% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-2640 v3 is also 100.0% better value on MSRP (11.8 vs 0.0 PassMark/$), 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 v4 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2014), 50% larger total L3 cache (30 MB vs 20 MB), and more multi-core headroom with 12 cores / 24 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
