Quick Answers

So, is Xeon E5-2637 v4 better than Xeon D-1537?

Yes. Xeon E5-2637 v4 is the better all-around CPU here. It gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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 E5-2637 v4 is the better pick. According to our tests, it delivers 0.6% 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 E5-2637 v4 is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 566.7% larger total L3 cache (10 MB vs 1.5 MB).

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

Xeon E5-2637 v4 is the easy recommendation for a fresh desktop build. Xeon E5-2637 v4 comes in at an unclear MSRP at unclear MSRP versus $470 MSRP, and it still gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data. Xeon D-1537 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Xeon E5-2637 v4 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2015), 566.7% larger total L3 cache (10 MB vs 1.5 MB), and more multi-core headroom with 4 cores / 8 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
