Quick Answers

So, is Xeon E3-1270 better than Xeon E3-1245?

Yes. Xeon E3-1270 is the better all-around CPU here. It gives you a 0.3% average FPS lead across 46 shared CPU game tests in our data, 0.6% 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 E3-1270 is the better pick. According to our tests, it delivers 0.3% more average FPS across 46 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon E3-1270 is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E3-1270 is the better buy right now. Xeon E3-1270 comes in at an unclear MSRP at $330 MSRP versus unclear MSRP, and it still gives you a 0.3% average FPS lead across 46 shared CPU game tests in our data. It is also 100.0% better value on MSRP (16.3 vs 0.0 PassMark/$), 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 E3-1270 makes more sense long term for 2026 and beyond. You are getting 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.
