Quick Answers

So, is Xeon E-2104G better than Core i5-8265U?

Not really, because they are built for different jobs. Xeon E-2104G makes more sense for workstation-style multi-core throughput, while Core i5-8265U 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, Xeon E-2104G is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Xeon E-2104G is the better buy right now. Xeon E-2104G comes in at an unclear MSRP at $193 MSRP versus unclear MSRP, and it still gives you 0.8% better PassMark. The compromise is that Core i5-8265U is still the better pure gaming CPU with a 13.0% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (30.4 vs 0.0 PassMark/$), 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 E-2104G is the safer long-term CPU choice because it gives you more room to grow and a better platform outlook.
