Xeon E-2174G

2018

Why buy it

✅Draws 71W instead of 112W, a 41W reduction.

Trade-offs

❌Lower PassMark (9,604 vs 9,678).

Quick Answers

So, is Xeon E-2174G better than Core i7-7740X?

Not really, because they are built for different jobs. Xeon E-2174G makes more sense for workstation-style multi-core throughput, while Core i7-7740X is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Core i7-7740X is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E-2174G is still the much better call for a fresh build. Xeon E-2174G comes in at an unclear MSRP at unclear MSRP versus $339 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Core i7-7740X only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (28.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2066.

Which one is more future-proof for 2026 and beyond?

Xeon E-2174G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2017). That makes it the safer long-term bet.
