Quick Answers

So, is Xeon E-2144G better than Xeon E5-4655 v3?

Yes. Xeon E-2144G is the better all-around CPU here. It gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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 E-2144G is the better pick. According to our tests, it delivers 0.3% 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 E-2144G is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E-2144G is still the faster CPU overall, but Xeon E5-4655 v3 is easier to justify if budget matters more than peak performance. Xeon E-2144G comes in 235.5% more expensive on MSRP at $2,090 MSRP versus $623 MSRP, and it still gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-4655 v3 is also 234.8% better value on MSRP (15.1 vs 4.5 PassMark/$), 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 E-2144G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2015) and more multi-core headroom with 4 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
