Not in a simple one-size-fits-all way. Xeon W-3375 makes more sense for workstation-style multi-core throughput, while Core i5-10400F 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-3375 is the better pick here. According to our tests, it delivers 75.1% more average FPS across 6 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon W-3375 is the better fit. You are getting 206.3% better Geekbench multi-core, backed by 38 cores and 76 threads. It also carries the larger cache pool with 375% larger total L3 cache (57 MB vs 12 MB).

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

Xeon W-3375 is still the faster CPU overall, but Core i5-10400F makes more sense if price matters more than absolute performance. Xeon W-3375 is 2994.4% more expensive on MSRP at $4,951 MSRP versus $160 MSRP, and it gives you a 75.1% average FPS lead across 6 shared CPU game tests in our data. Core i5-10400F is also 582.3% better value on MSRP (81.4 vs 11.9 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

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

Xeon W-3375 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2020), 375% larger total L3 cache (57 MB vs 12 MB), more multi-core headroom with 38 cores / 76 threads instead of 6/12, 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.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
