AMD Opteron 8222

The AMD Opteron 8222 is a dual-core server processor from the Santa Rosa generation, built on the K8 architecture at a 90 nm process node. It operates at a base clock of 3.00, with a TDP of 95, and targets the server/workstation segment. The processor is end-of-life, with a launch MSRP of $1514. The part number is OSA8222GAA6CY.

Benchmark Performance

The benchmark data for the Opteron 8222 is minimal, with an average benchmark score of 0 and a percentile versus all CPUs of 50. This combination indicates that the database has no recorded benchmark results for this part. The zero average score is a placeholder, not a measured value, and the 50th percentile is the neutral median position. Because the benchmarks array is empty, there are no synthetic or real-world test scores to analyze. The nearestRivals field is also empty, meaning no rival names, scores, or deltaPct values are available for comparison. Consequently, the performance analysis must be derived from the architectural parameters.

The processor has 2 cores and 2 threads, indicating a symmetric dual-core design without simultaneous multithreading. The base clock is fixed at 3.00, with no boost clock listed, so the processor operates at a constant frequency under load. The cache hierarchy includes a 128 KB L1 cache per core and a 1 MB L2 cache per core. This cache size is substantial for a dual-core part, potentially improving performance in cache-sensitive workloads. The memory bandwidth is 10.7 GB/s over a dual-channel DDR2 bus, which provides a moderate data transfer rate for the era.

The 50th percentile placement suggests that, in the context of the entire CPU database, this processor is positioned exactly in the middle. However, this is an artifact of the missing data rather than a performance verdict. Without measured scores, the actual performance relative to other CPUs cannot be quantified. The data shows a dual-core processor with a high clock for its time, but the lack of benchmarks leaves its practical performance unverified. The 90 nm process node and 227 million transistors suggest a mature design, but the performance implications are speculative. The absence of a boost clock means the processor's performance is predictable and consistent, but it also caps peak throughput at the base frequency. The 2 MB total L2 cache (1 MB per core) provides a large working set for each core, which can mitigate some memory latency penalties. The dual-channel memory bus, while standard, delivers a fixed bandwidth of 10.7 GB/s that could become a bottleneck for memory-intensive workloads. In summary, the benchmark section provides no actionable performance numbers, and the 50th percentile is a neutral placeholder.

Platform and Compatibility

The Opteron 8222 is designed for the AMD Socket F, a socket that was used for high-end server processors in the K8 era. Memory support is limited to DDR2, operating in a dual-channel configuration, which yields a theoretical memory bandwidth of 10.7 GB/s. The inclusion of ECC memory support is a critical feature for server reliability, allowing error correction in memory-heavy workloads. The processor exposes a PCIe Gen 1 interface, which is the first generation of the PCIe standard, providing a baseline for expansion cards and controllers. The processor does not include integrated graphics, so a discrete GPU or a server management controller is necessary for display output. The market segment is explicitly Server/Workstation, confirming its intended use. The production status is end-of-life, meaning it is no longer manufactured or actively supported. The release date is recorded as 2007-08-04, placing it in the third quarter of 2007. The part number OSA8222GAA6CY identifies the specific SKU.

The architecture is K8, codenamed Santa Rosa, and the generation is listed as Opteron (Santa Rosa). The process node is 90 nm, with a die size of 235 mm² and a transistor count of 227 million. These physical characteristics are typical for a mid-2000s server chip. The socket F platform is a legacy platform, so upgrade paths are limited to other Socket F processors, though none are listed in the nearestRivals field. The dual-channel memory bus is a standard configuration for the time, and the 10.7 GB/s bandwidth is a direct function of the memory clock and bus width. The PCIe Gen 1 interface supports a maximum theoretical bandwidth per lane, but the exact lane count is not specified in the data. The absence of an integrated GPU means that the platform requires a separate graphics adapter, which is common for servers. The ECC memory support is a mandatory feature for error-free operation in scientific and financial workloads. The 90 nm process node, while smaller than earlier nodes, still produces a 235 mm² die, which is relatively large. The transistor count of 227 million reflects the complexity of the dual-core design. The socket F platform is not forward-compatible with newer AMD sockets, limiting the upgrade path to other Socket F processors from the same generation. Overall, the platform is a mature, legacy server platform with standard features for its era.

Power and Thermals

The thermal design power (TDP) is 95, which is a moderate figure for a dual-core server processor. This TDP class implies that a standard air cooler designed for server sockets will suffice; the data does not indicate the need for liquid cooling or exotic thermal solutions. The 90 nm process node is relatively large by modern standards, but it was a common node for the 2007 timeframe. The die size is 235 mm², and the transistor count is 227 million. The combination of a 95 W TDP and a 3.00 base clock suggests a balance between performance and power draw. The multiplier is not unlocked, so the processor operates at a fixed clock multiplier, preventing user overclocking. For thermal management, the 95 W envelope is within the range that standard server chassis fans can handle. The lack of a boost clock means the processor runs at a constant 3.00, which simplifies thermal behavior—there are no transient power spikes from boost states. The data shows a single, steady thermal load.

The 235 mm² die size provides a large surface area for heat spread, aiding in thermal dissipation. The 95 W TDP is a key specification for system integrators, as it dictates the cooling solution and power supply requirements. Since the multiplier is locked, there is no headroom for manual frequency adjustment, which keeps the thermal profile predictable. The 90 nm process node has a higher leakage current compared to smaller nodes, but the 95 W TDP indicates that the design has been optimized to stay within that envelope. The absence of a boost clock also means that the maximum power draw is equal to the TDP, simplifying power supply sizing. The processor's thermal output is steady and predictable, which is advantageous for dense server deployments where cooling capacity is planned around a fixed heat load. The 95 W TDP is a moderate value, placing it in the same class as many contemporary dual-core server parts, though no specific rivals are listed. Overall, the thermal requirements are modest, fitting into a conventional air-cooled server environment.

How It Compares

The nearestRivals field for the AMD Opteron 8222 is empty. This means the database does not list any rival processors with associated scores or deltaPct values for this part. Consequently, no direct percentage comparisons can be made against specific competitors. The only comparative data point available is the percentile versus all CPUs, which is 50. This percentile indicates that the processor sits at the exact median of the entire CPU database. However, because the average benchmark score is 0 and the benchmarks array is empty, this percentile is not derived from measured performance but is a default neutral value. Without rival names, the analysis cannot state that it is ahead of or behind any particular chip. The absence of rivals is notable, suggesting that the database has not been populated with comparisons for this end-of-life processor. The 50th percentile placement, while mathematically central, carries no performance weight. In the context of the database, the processor is positioned in the middle, but this is a placeholder. The architectural specifications, such as the 3.00 base clock and dual-core design, would typically place it in the mid-range of its era, but without measured scores, this is speculative. The data shows no rivals to compare against, so the analysis is limited to the percentile field. The 50th percentile is a neutral indicator, and the absence of deltaPct values means no percentage advantages or disadvantages can be stated. In summary, the Opteron 8222's position in the database is defined by its architectural specifications and a neutral percentile, with no rival comparisons available to contextualize its performance.
