Core i7-7820X

2017

Why buy it

    Trade-offs

    • Worse for gaming: lower average FPS than Xeon W-1270 across 50 shared CPU benchmark tests.
    • Lower PassMark (17,171 vs 17,456).
    • Smaller total L3 cache (11 MB vs 16 MB).
    • Launch MSRP is still $599 MSRP, while Xeon W-1270 mostly shows up through inconsistent older-market listings.
    • 75% higher power demand at 140W vs 80W.

    Xeon W-1270

    2020

    Why buy it

    Quick Answers

    So, is Xeon W-1270 better than Core i7-7820X?
    Not really, because they are built for different jobs. Xeon W-1270 makes more sense for workstation-style multi-core throughput, while Core i7-7820X 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 W-1270 is the better pick. According to our tests, it delivers 4.7% 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 W-1270 is the stronger fit. You are getting 1.7% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 45.5% larger total L3 cache (16 MB vs 11 MB).
    Which one is the smarter buy today, not just the cheaper CPU?
    Xeon W-1270 is still the much better call for a fresh build. Xeon W-1270 comes in at an unclear MSRP at unclear MSRP versus $599 MSRP, and it still gives you a 4.7% average FPS lead across 50 shared CPU game tests in our data. Core i7-7820X only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (28.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2066.
    Which one is more future-proof for 2026 and beyond?
    Xeon W-1270 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2017), 45.5% larger total L3 cache (16 MB vs 11 MB), and more multi-core headroom with 8 cores / 16 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
