Quick Answers

So, is Core i7-4820K better than Xeon W3670?
Not really, because they are built for different jobs. Xeon W3670 makes more sense for workstation-style multi-core throughput, while Core i7-4820K is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
If gaming is the priority, Core i7-4820K is the better pick. According to our tests, it delivers 3.0% 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, Core i7-4820K is the stronger fit. You are getting 1.4% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-4820K is still the faster CPU overall, but Xeon W3670 is easier to justify if budget matters more than peak performance. Core i7-4820K comes in 32.8% more expensive on MSRP at $332 MSRP versus $250 MSRP, and it still gives you a 3.0% average FPS lead across 50 shared CPU game tests in our data. Xeon W3670 is also 30.9% better value on MSRP (25.7 vs 19.6 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
Core i7-4820K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2010) and more multi-core headroom with 4 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
