Core i3-8300 vs Xeon W3670: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i3-8300

2018

Why buy it

  • Costs $112 less on MSRP ($138 MSRP vs $250 MSRP).
  • Delivers 79.6% more PassMark for each dollar spent, at 46.2 vs 25.7 PassMark/$ ($138 MSRP vs $250 MSRP).
  • Draws 62W instead of 130W, a 68W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Xeon W3670 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon W3670 across 50 shared CPU benchmark tests.
  • Lower PassMark (6,370 vs 6,424).
  • Smaller total L3 cache (8 MB vs 12 MB).
  • Less compelling for workstation-style loads than Xeon W3670, which brings 6 cores / 12 threads.

Xeon W3670

2010

Why buy it

  • Better for gaming: +5.8% higher average FPS across 50 shared CPU benchmark tests.
  • +50% larger total L3 cache (12 MB vs 8 MB).
  • Better for workstations and heavier parallel workloads: 6 cores / 12 threads.

Trade-offs

  • Lower PassMark per dollar, at 25.7 vs 46.2 PassMark/$ ($250 MSRP vs $138 MSRP).
  • 109.7% higher power demand at 130W vs 62W.
  • No integrated graphics, while Core i3-8300 can still boot and troubleshoot without a discrete GPU.
  • No boxed cooler included, unlike Core i3-8300.

Quick Answers

So, is Xeon W3670 better than Core i3-8300?
Not really, because they are built for different jobs. Xeon W3670 makes more sense for workstation-style multi-core throughput, while Core i3-8300 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 W3670 is the better pick. According to our tests, it delivers 5.8% 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 W3670 is the stronger fit. You are getting 0.8% better PassMark, backed by 6 cores and 12 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 W3670 is still the much better call for a fresh build. Xeon W3670 comes in 81.2% more expensive on MSRP at $250 MSRP versus $138 MSRP, and it still gives you a 5.8% average FPS lead across 50 shared CPU game tests in our data. Core i3-8300 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 79.6% better value on paper (46.2 vs 25.7 PassMark/$), 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 i3-8300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2010). That makes it the safer long-term bet.
