Quick Answers

So, is Xeon L5640 better than Xeon E3-1220 v2?
It depends on what matters more to you. For gaming, Xeon L5640 is ahead with a 5.6% average FPS lead across 5 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon E3-1220 v2 pulls ahead with 0.5% better PassMark. Xeon L5640 also has the bigger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Xeon E3-1220 v2 is the better fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon L5640 is the smarter buy today. Xeon L5640 is at an unclear MSRP at $996 MSRP versus unclear MSRP, and it gives you a 5.6% average FPS lead across 5 shared CPU game tests in our data. The trade-off is that Xeon E3-1220 v2 is still stronger for heavier multi-core work with 0.5% better PassMark. It is also 100.0% better value on MSRP (4.7 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.
Which one is more future-proof for 2026 and beyond?
Xeon E3-1220 v2 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 6/12. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
