Quick Answers

So, is Xeon E3-1235L v5 better than Xeon E5-1607 v3?

It depends on what you want from the system. For gaming, Xeon E5-1607 v3 is ahead with a 8.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon E3-1235L v5 pulls ahead with 1.6% better PassMark. Xeon E5-1607 v3 also has the bigger cache pool with 25% larger total L3 cache (10 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Xeon E3-1235L v5 is the stronger fit. You are getting 1.6% better PassMark, backed by 4 cores and 4 threads.

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

Xeon E3-1235L v5 still makes the most sense overall. Xeon E3-1235L v5 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1.6% better PassMark.

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

Xeon E3-1235L v5 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014) and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
