Quick Answers

So, is Xeon E3-1285 v4 better than Core i5-8500T?

Not really, because they are built for different jobs. Xeon E3-1285 v4 makes more sense for workstation-style multi-core throughput, while Core i5-8500T 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 E3-1285 v4 is the better pick. According to our tests, it delivers 12.6% 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 E3-1285 v4 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.

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

Xeon E3-1285 v4 is still the much better call for a fresh build. Xeon E3-1285 v4 comes in 189.6% more expensive on MSRP at $556 MSRP versus $192 MSRP, and it still gives you a 12.6% average FPS lead across 50 shared CPU game tests in our data. Core i5-8500T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 189.4% better value on paper (40.3 vs 13.9 PassMark/$), 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 i5-8500T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2015) and 50% larger total L3 cache (9 MB vs 6 MB). That makes it the safer long-term bet.
