Quick Answers

So, is Xeon E5-2637 v4 better than Xeon E3-1505M v6?

Yes. Xeon E5-2637 v4 is the better all-around CPU here. It gives you a 6.7% average FPS lead across 50 shared CPU game tests in our data and 0.3% better PassMark, 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 6.7% 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 0.3% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 25% larger total L3 cache (10 MB vs 8 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 $434 MSRP, and it still gives you a 6.7% average FPS lead across 50 shared CPU game tests in our data. Xeon E3-1505M v6 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, especially when the gap is already 6.7% in the shared gaming data.

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

Xeon E3-1505M v6 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2016). That makes it the safer long-term bet.
