Quick Answers

So, is Xeon D-1587 better than Xeon E5-2670 v3?

It depends on what you want from the system. For gaming, Xeon E5-2670 v3 is ahead with a 2.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon D-1587 pulls ahead with 1% better PassMark. Xeon E5-2670 v3 also has the bigger cache pool with 1900% larger total L3 cache (30 MB vs 1.5 MB).

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

For streaming, content creation, and heavier multitasking, Xeon D-1587 is the stronger fit. You are getting 1% better PassMark, backed by 16 cores and 32 threads.

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

Xeon D-1587 is the better buy right now. Xeon D-1587 comes in at an unclear MSRP at $1,652 MSRP versus unclear MSRP, and it still gives you 1% better PassMark. The compromise is that Xeon E5-2670 v3 is still the better pure gaming CPU with a 2.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (8.3 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon D-1587 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2014) and more multi-core headroom with 16 cores / 32 threads instead of 12/24. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
