AMD SP7 vs Intel LGA9324: server sockets built for 1,400W CPUs

Key Takeaways

• AMD's SP7 socket can deliver up to 1,400W peak power for 256-core EPYC Venice processors arriving late 2026
• Intel's LGA9324-1 socket uses 9,324 pins for Diamond Rapids Xeons with up to 192 cores, launching 2027
• Both platforms support 16-channel memory and PCIe 6.0, requiring liquid cooling for AI server deployments

AMD and Intel showed their next-generation server sockets at Computex 2026, and both are enormous. AMD's SP7 socket will support 256-core EPYC Venice processors with peak power delivery of 1,400W. Intel's competing LGA9324-1, with 9,324 contact points, will power Diamond Rapids Xeons starting 2027. These sockets are not incremental upgrades. They represent a fundamental shift in how server processors handle power and I/O for AI workloads.

What does AMD's SP7 socket actually support?

The SP7 is AMD's socket for 6th-generation EPYC Venice processors. According to information from cooling vendor Auras, the socket handles CPUs consuming up to 1,400W at peak. That figure alone explains why liquid cooling is mandatory, not optional, for these chips.

The platform supports 16 DDR6 memory channels using 12.8 GT/s MRDIMMs and up to 96 PCIe 6.0 lanes with CXL protocol support. Venice processors will pack up to 256 cores. The socket is physically massive, covering most of an adult palm, but it remains compact enough for dual-socket server designs. That means systems with 512 x86 cores become possible when Venice ships later this year.

AMD is also preparing a smaller SP8 platform for customers who do not need the full core count or memory bandwidth. Auras is building water blocks for SP8 as well, suggesting these chips will still draw substantial power despite the reduced specifications.

How does Intel's 9,324-pin socket compare?

Intel's LGA9324-1 socket is larger than AMD's SP7. Physically, it extends beyond the length of a human palm. The socket will support Xeon Diamond Rapids processors with up to 192 cores, a 16-channel DDR5 memory subsystem using MRDIMMs, and PCIe Gen6 lanes.

Intel has not announced official power specifications for Diamond Rapids. Based on Auras preparing water blocks for these processors, Tom's Hardware estimates processor base power between 300W and 500W, with peak consumption exceeding 1kW. The socket's size suggests it could also support Coral Rapids processors, which are expected around 2028 or 2029.

Why are these sockets so large?

The socket dimensions are a direct consequence of power delivery and I/O requirements. Supporting 16 memory channels and dozens of PCIe 6.0 lanes requires physical space for the electrical traces. Delivering over 1kW of power to a processor requires substantial contact area to manage current flow without overheating.

This is not overengineering. AI training and inference workloads demand memory bandwidth that DDR5 systems cannot provide at scale. Both AMD and Intel are building platforms that treat the CPU as a central hub for massive data movement, not just computation. The socket becomes the bottleneck if it cannot supply enough power or route enough signals.

What does this mean for AI server infrastructure?

Data center operators will need to upgrade cooling infrastructure significantly. Liquid cooling is not optional for either platform at full power draw. The 1,400W peak for AMD Venice and estimated 1kW+ for Diamond Rapids exceed what air cooling can handle efficiently.

Power delivery to racks becomes a serious constraint. A dual-socket AMD Venice server at full load could draw nearly 3kW just for the CPUs, before accounting for memory, storage, and networking. Data centers designed for 10-15kW per rack will need substantial upgrades to deploy these systems at density.

The timeline favors AMD. Venice arrives late 2026, giving AMD roughly a year head start over Intel's Diamond Rapids. For enterprises planning AI infrastructure buildouts, that gap matters. Waiting for Intel means delaying deployments; committing to AMD means potential vendor lock-in if Intel delivers compelling price-performance in 2027.

Frequently Asked Questions
