AMD OSP8216GAA6CR Dual Core HE Server Processor

The OSP8216GAA6CR is an AMD Opteron Model 8216 dual-core processor built for the 940-pin micro PGA socket, with a 68W thermal design power that positions it as the HE (High Efficiency) variant of the 8000 series — a relevant distinction if you're planning density in a multi-socket server chassis with tight thermal or power budgets.

Key Features

• 68W Thermal Design Power: The HE designation matters here — 68W is meaningfully lower than standard Opteron 8000-series parts, which reduces per-socket cooling load in dense 4P/8P server builds where thermal headroom is often the limiting factor.
• 940-Pin micro PGA Package, 1.27mm Pin Pitch: Defines your socket and motherboard compatibility requirements directly — confirm your board's socket revision before ordering, since pin pitch and package size (40mm x 40mm substrate) are not interchangeable across Opteron generations.
• Dual Core Architecture: Two physical cores on a single die for workloads that benefit from parallel execution without the power draw of higher core-count parts in the same family.
• 1024KB (1MB) L2 Cache: A full megabyte of L2 sitting close to the cores reduces main-memory round trips on cache-sensitive workloads, which matters more on older-generation memory subsystems than raw clock speed alone.
• 64KB L1 Data + 64KB L1 Instruction Cache: Split L1 design keeps instruction fetch and data access from contending for the same cache lines — standard practice for predictable per-core latency.
• HyperTransport at 2000 MT/s: Governs inter-socket and chipset communication bandwidth in multi-processor Opteron platforms — a factor if this CPU is going into a 2P or 4P board alongside other 8000-series parts.
• 200MHz DDR SDRAM Speed: Sets the memory controller's supported DDR clock — plan your DIMM selection around this ceiling rather than assuming compatibility with newer, faster memory.

Integration & Compatibility

Socket and platform compatibility for the OSP8216GAA6CR is defined entirely by the 940-pin micro PGA package and 40mm x 40mm substrate — verify your server board's socket revision and BIOS support before purchasing, since Opteron 8000-series boards are not universally cross-compatible across sub-generations.

Frequently Asked Questions

Ted Perry

The OSP8216GAA6CR is one I'd flag specifically for its 68W TDP — that's the HE variant of the Opteron 8216, and in a 4-socket or 8-socket chassis that thermal delta adds up fast across sockets.

Technical Highlights:

• 68W TDP: Lower per-socket heat load than standard Opteron 8000-series parts, which matters directly for cooling design in multi-socket density builds.
• 1024KB L2 Cache: A full megabyte of L2 per core pairing reduces memory latency exposure on cache-sensitive workloads running on this platform.
• 2000 MT/s HyperTransport: Sets the ceiling on inter-socket bandwidth in multi-processor Opteron configurations — relevant if you're pairing multiple 8216 units on one board.

Deployment Considerations:

• Confirm your motherboard's 940-pin socket revision and BIOS microcode support before ordering — Opteron 8000-series compatibility is not universal across board generations.
• The 200MHz DDR SDRAM speed ceiling means your memory selection needs to match this controller's supported clock rather than assuming forward compatibility with newer DIMMs.

This part fits a legacy 4P/8P Opteron server rebuild or maintenance replacement where matching the existing platform's socket and thermal envelope matters more than raw throughput — not a fit for new build-outs where current-generation platforms make more sense.
