Quick Answers

So, is Xeon D-1577 better than Xeon E5-4628L v4?

It depends on what you want from the system. For gaming, Xeon E5-4628L v4 is ahead with a 5.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon D-1577 pulls ahead with 1.2% better PassMark. Xeon E5-4628L v4 also has the bigger cache pool with 2233.3% larger total L3 cache (35 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-1577 is the stronger fit. You are getting 1.2% better PassMark, backed by 16 cores and 32 threads.

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

Xeon D-1577 still makes the most sense overall. Xeon D-1577 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1.2% better PassMark.

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

Xeon D-1577 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 16 cores / 32 threads instead of 14/28. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
