Quick Answers

So, is Xeon Platinum 8481C better than Xeon D-1577?

Yes. Xeon Platinum 8481C is the better all-around CPU here. It gives you a 10.0% average FPS lead across 50 shared CPU game tests in our data, 0.3% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon Platinum 8481C is the better pick. According to our tests, it delivers 10.0% more average FPS across 50 shared CPU game tests. It also has a clear cache advantage at 105 MB versus 1.5 MB.

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

For streaming, content creation, and heavier multitasking, Xeon Platinum 8481C is the stronger fit. You are getting 0.3% better PassMark, backed by 56 cores and 112 threads. It also has the larger cache pool with 6900% larger total L3 cache (105 MB vs 1.5 MB).

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

Xeon Platinum 8481C still makes the most sense overall. Xeon Platinum 8481C comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 10.0% average FPS lead across 50 shared CPU game tests in our data.

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

Xeon Platinum 8481C makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2016), a healthier platform with LGA4677 and DDR5 instead of FCBGA1667, 3D V-Cache and a much larger 105 MB L3 cache instead of 1.5 MB, and more multi-core headroom with 56 cores / 112 threads instead of 16/32. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
