Quick Answers

So, is Xeon E5-1620 v3 better than Xeon E5-4607?

It depends on what you want from the system. For gaming, Xeon E5-1620 v3 is ahead with a 7.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon E5-4607 pulls ahead with 0.4% better PassMark. Xeon E5-4607 also has the bigger cache pool with 50% larger total L3 cache (15 MB vs 10 MB).

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

For streaming, content creation, and heavier multitasking, Xeon E5-4607 is the stronger fit. You are getting 0.4% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (15 MB vs 10 MB).

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

Xeon E5-1620 v3 is the better buy right now. Xeon E5-1620 v3 comes in at an unclear MSRP at $294 MSRP versus unclear MSRP, and it still gives you a 7.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E5-4607 is still stronger for heavier multi-core work with 0.4% better PassMark. It is also 100.0% better value on MSRP (23.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon E5-1620 v3 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012) and AVX-512 support for heavier modern compute workloads. That makes it the safer long-term bet.
