Quick Answers

So, is Xeon 6357P better than Core i5-10400F?

Not in a simple one-size-fits-all way. Xeon 6357P 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 6357P is the better pick here. According to our tests, it delivers 23.7% more average FPS across 45 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon 6357P is the better fit. You are getting 119.8% better Cinebench R23 multi-core, backed by 8 cores and 16 threads. It also carries the larger cache pool with 100% larger total L3 cache (24 MB vs 12 MB).

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

Xeon 6357P is the smarter buy by a wide margin for a fresh build. Xeon 6357P is at an unclear MSRP at unclear MSRP versus $160 MSRP, and it gives you a 23.7% average FPS lead across 45 shared CPU game tests in our data. Core i5-10400F only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2020 platform. Even with 100.0% better value on paper (81.4 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1200.

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

Xeon 6357P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2020), a healthier platform with LGA1700 and DDR5 instead of LGA1200, 100% larger total L3 cache (24 MB vs 12 MB), more multi-core headroom with 8 cores / 16 threads instead of 6/12, and AVX-512 support for heavier modern compute workloads. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

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.
