Quick Answers

So, is Xeon D-1726 better than Xeon E5-4667 v3?

It depends on what you want from the system. For gaming, Xeon E5-4667 v3 is ahead with a 23.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon D-1726 pulls ahead with 0.7% better PassMark. Xeon E5-4667 v3 also has the bigger cache pool with 300% larger total L3 cache (40 MB vs 10 MB).

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

For streaming, content creation, and heavier multitasking, Xeon D-1726 is the stronger fit. You are getting 0.7% better PassMark, backed by 6 cores and 12 threads.

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

Xeon D-1726 is still the faster CPU overall, but Xeon E5-4667 v3 is easier to justify if budget matters more than peak performance. Xeon D-1726 comes in at an unclear MSRP at unclear MSRP versus $128 MSRP, and it still gives you 0.7% better PassMark. The compromise is that Xeon E5-4667 v3 is still the better pure gaming CPU with a 23.7% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-4667 v3 is also 100.0% better value on MSRP (120.3 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Xeon D-1726 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2015) and more multi-core headroom with 6 cores / 12 threads instead of 16/32. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
