Quick Answers

So, is Xeon X5687 better than Core i3-8300T?

Not really, because they are built for different jobs. Xeon X5687 makes more sense for workstation-style multi-core throughput, while Core i3-8300T 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 X5687 is the better pick. According to our tests, it delivers 15.6% 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 X5687 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Xeon X5687 is still the much better call for a fresh build. Xeon X5687 comes in 300.0% more expensive on MSRP at $552 MSRP versus $138 MSRP, and it still gives you a 15.6% average FPS lead across 50 shared CPU game tests in our data. Core i3-8300T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 299.4% better value on paper (39.0 vs 9.8 PassMark/$), 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 i3-8300T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2011). That makes it the safer long-term bet.
