Quick Answers

So, is Xeon E5-2623 v4 better than Xeon D-1528?

Yes. Xeon E5-2623 v4 is the better all-around CPU here. It gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data, 0.7% 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 E5-2623 v4 is the better pick. According to our tests, it delivers 0.5% 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 E5-2623 v4 is the stronger fit. You are getting 0.7% 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 E5-2623 v4 still makes the most sense overall. Xeon E5-2623 v4 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data.

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

Xeon E5-2623 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 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
