Quick Answers

So, is Xeon D-2146NT better than Xeon E5-4657L v2?

It depends on what you want from the system. For gaming, Xeon E5-4657L v2 is ahead with a 9.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon D-2146NT pulls ahead with 1.1% better PassMark. Xeon E5-4657L v2 also has the bigger cache pool with 172.7% larger total L3 cache (30 MB vs 11 MB).

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

For streaming, content creation, and heavier multitasking, Xeon D-2146NT is the stronger fit. You are getting 1.1% better PassMark, backed by 8 cores and 16 threads.

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

Xeon D-2146NT still makes the most sense overall. Xeon D-2146NT comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1.1% better PassMark.

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

Xeon D-2146NT makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2014) and more multi-core headroom with 8 cores / 16 threads instead of 12/24. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
