Quick Answers

So, is Xeon W-3345 better than Core i7-9700K?

Not in a simple one-size-fits-all way. Xeon W-3345 makes more sense for workstation-style multi-core throughput, while Core i7-9700K is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

Which one is better for gaming?

If gaming is the priority, Xeon W-3345 is the better pick here. According to our tests, it delivers 58.8% more average FPS across 4 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon W-3345 is the better fit. You are getting 234.4% better PassMark, backed by 24 cores and 48 threads. It also carries the larger cache pool with 200% larger total L3 cache (36 MB vs 12 MB).

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

Xeon W-3345 is the smarter buy by a wide margin for a fresh build. Xeon W-3345 is 549.1% more expensive on MSRP at $2,499 MSRP versus $385 MSRP, and it gives you a 58.8% average FPS lead across 4 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 94.1% better value on paper (37.4 vs 19.3 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Xeon W-3345 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2018), 200% larger total L3 cache (36 MB vs 12 MB), more multi-core headroom with 24 cores / 48 threads instead of 8/8, and AVX-512 support for heavier modern compute workloads. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
