Xeon Gold 6530 vs Xeon Gold 6338
The Xeon Gold 6530 and the Xeon Gold 6338 are both server processors we supply tested from Hong Kong, and the figures below are the same ones published on each product page. They share 1 listed specification row and separate on tdp, cache, memory, so the decision is less about "which is better" and more about which of those differences your platform or workload can actually use.
Nothing on this page is a price: component pricing moved too fast in 2026 for a printed figure to stay honest, so both are quoted on request against confirmed stock with the date the quote holds until. If you are replacing a part, send the platform and we will confirm the population before you commit.

Rows that differ are highlighted. Figures are the same ones published on each product page; where a figure is community-sourced rather than vendor-published it is stated on that page. Confirm every part against your build sheet when ordering.
Where they differ
- ·Xeon Gold 6338 is the better figure for power draw (270 W / Intel 7 vs 205W).
- ·Xeon Gold 6530 has the higher cache (160 vs 48); Xeon Gold 6338 trades that for something else.
- ·Memory — Xeon Gold 6530: DDR5 @ 4800 MT/s (1 DPC), 8 channels; Xeon Gold 6338: 8-channel DDR4-3200, ECC, up to 4,096GB per socket.
- ·PCIe — Xeon Gold 6530: PCIe 5.0, up to 80 lanes / up to 3 UPI links; Xeon Gold 6338: PCIe 4.0, 64 lanes.
- ·Xeon Gold 6530 lists the higher base clock (2.1 GHz base / 4 GHz max turbo vs 2.0GHz base).
What they share
Cores / Threads: 32 cores / 64 threads.
Decision
Which one to buy
For processors the useful split is throughput versus frequency. More cores per socket wins on virtualisation density, parallel batch work and multi-tenant hosting, where the scheduler can keep every core busy; higher base and boost clocks win where the workload is latency-sensitive or licensed per core, and the extra cores would sit idle. Check the socket and the platform's memory generation before anything else: a CPU is only useful in a board that takes it, and the two models above are interchangeable only when the socket matches. TDP also sets the cooling and power budget per node.
Choose the Xeon Gold 6530 if
- ·You need more cache — the Xeon Gold 6530 lists 160 MB against 48MB L3 on the Xeon Gold 6338.
- ·Memory: DDR5 @ 4800 MT/s (1 DPC), 8 channels
- ·PCIe: PCIe 5.0, up to 80 lanes / up to 3 UPI links
Choose the Xeon Gold 6338 if
- ·You need lower power draw — the Xeon Gold 6338 lists 205W against 270 W / Intel 7 on the Xeon Gold 6530.
- ·Memory: 8-channel DDR4-3200, ECC, up to 4,096GB per socket
- ·PCIe: PCIe 4.0, 64 lanes

Frequently asked questions
How much do the Xeon Gold 6530 and the Xeon Gold 6338 cost?
We do not publish prices for either: DRAM and CPU pricing moved too fast in 2026 for a printed figure to stay honest. Send the quantity, the platform and the condition you want and we quote both against confirmed stock, with the date the figure holds until.
What is the main difference between the Xeon Gold 6530 and the Xeon Gold 6338?
TDP (Xeon Gold 6530: 270 W / Intel 7; Xeon Gold 6338: 205W); Cache (Xeon Gold 6530: 160 MB; Xeon Gold 6338: 48MB L3); Memory (Xeon Gold 6530: DDR5 @ 4800 MT/s (1 DPC), 8 channels; Xeon Gold 6338: 8-channel DDR4-3200, ECC, up to 4,096GB per socket).
Can I use the Xeon Gold 6530 and the Xeon Gold 6338 in the same system?
No. They use different sockets (see spec vs LGA4189 (Socket P+)), so they need different server platforms and cannot share a board.
Which one should I buy?
Buy the one whose strong points match the job: see the "Choose" section above. If you are replacing an existing part, send the platform or the old part number and we will confirm compatibility before you order.
What condition are they in, and do you ship worldwide?
Both are supplied tested with a 1-year written warranty. Condition is stated line by line before you order — new, decommissioned pull or OEM tray — and we ship worldwide from the Hong Kong warehouse with full export documentation, typically 3–7 days by air.
