Quick Answers

So, is Xeon Gold 5122 better than Xeon E3-1240 v6?

It depends on what you want from the system. For gaming, Xeon E3-1240 v6 is ahead with a 2.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon Gold 5122 pulls ahead with 1.6% better PassMark. Xeon Gold 5122 also has the bigger cache pool with 106.3% larger total L3 cache (17 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Xeon Gold 5122 is the stronger fit. You are getting 1.6% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 106.3% larger total L3 cache (17 MB vs 8 MB).

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

Xeon Gold 5122 still makes the most sense overall. Xeon Gold 5122 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 Gold 5122 makes more sense long term for 2026 and beyond. You are getting 106.3% larger total L3 cache (17 MB vs 8 MB) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
