Quick Answers

So, is Xeon E3-1225 v3 better than Core i3-8100T?

Not really, because they are built for different jobs. Xeon E3-1225 v3 makes more sense for workstation-style multi-core throughput, while Core i3-8100T is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon E3-1225 v3 is the better pick. According to our tests, it delivers 0.8% 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 E3-1225 v3 is the stronger fit. You are getting 1.3% 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 E3-1225 v3 is still the much better call for a fresh build. Xeon E3-1225 v3 comes in 91.5% more expensive on MSRP at $224 MSRP versus $117 MSRP, and it still gives you a 0.8% average FPS lead across 50 shared CPU game tests in our data. Core i3-8100T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 89.0% better value on paper (44.9 vs 23.8 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i3-8100T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2013). That makes it the safer long-term bet.
