✅60% more PCIe lanes (128 vs 80) for storage and expansion-heavy builds.

Trade-offs

❌Lower PassMark (69,432 vs 70,292).
❌Lower PassMark per dollar, at 12.4 vs 19.2 PassMark/$ ($5,590 MSRP vs $3,658 MSRP).
❌Older platform position on SP3 with DDR4, while Xeon Gold 6448H moves to LGA4677 and DDR5.

Xeon Gold 6448H

2023

Why buy it

✅+1.2% higher PassMark.
✅Costs $1,932 less on MSRP ($3,658 MSRP vs $5,590 MSRP).
✅Delivers 54.7% more PassMark for each dollar spent, at 19.2 vs 12.4 PassMark/$ ($3,658 MSRP vs $5,590 MSRP).
✅Draws 250W instead of 280W, a 30W reduction.

Quick Answers

So, is Xeon Gold 6448H better than EPYC 7573X?

It depends on what you want from the system. For gaming, EPYC 7573X is ahead with a 1.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon Gold 6448H pulls ahead with 1.2% better PassMark. EPYC 7573X also has the bigger cache pool with 1180% larger total L3 cache (768 MB vs 60 MB).

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

For streaming, content creation, and heavier multitasking, Xeon Gold 6448H is the stronger fit. You are getting 1.2% better PassMark, backed by 32 cores and 64 threads.

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

Xeon Gold 6448H is the better buy right now. Xeon Gold 6448H comes in $1,932 cheaper on MSRP at $3,658 MSRP versus $5,590 MSRP, and it still gives you 1.2% better PassMark. The compromise is that EPYC 7573X is still the better pure gaming CPU with a 1.5% average FPS lead across 50 shared CPU game tests in our data. It is also 54.7% better value on MSRP (19.2 vs 12.4 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon Gold 6448H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2022), a healthier platform with LGA4677 and DDR5 instead of SP3, more multi-core headroom with 32 cores / 64 threads instead of 32/64, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
