Quick Answers

So, is Xeon E3-1240L v5 better than Xeon E7340?

Yes. Xeon E3-1240L v5 is the better all-around CPU here. It gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data, 0% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon E3-1240L v5 is the better pick. According to our tests, it delivers 0.9% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon E3-1240L v5 is the stronger fit. You are getting 0% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E3-1240L v5 is still the faster CPU overall, but Xeon E7340 is easier to justify if budget matters more than peak performance. Xeon E3-1240L v5 comes in at an unclear MSRP at unclear MSRP versus $213 MSRP, and it still gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data. Xeon E7340 is also 100.0% better value on MSRP (30.7 vs 0.0 PassMark/$), 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 E3-1240L v5 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2007). That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
