AMD Opteron 848 HE

The AMD Opteron 848 HE is a single-core, single-thread server processor built on the K8 architecture with the Athens codename. It operates at a fixed 2.20 GHz base clock with no boost capability, and is rated at a 55 W TDP. Fabricated on a 90 nm process with 106 million transistors, it features a 128 KB L1 cache and a 1 MB L2 cache. It uses the AMD Socket 940, supports a dual-channel memory bus, and includes PCIe Gen 2 connectivity. The data set records no individual benchmark scores, an average benchmark score of 0, and a percentile ranking of 50 against all CPUs. It is marked as end-of-life, was released in February 2005, and carries the part number OSK848FAA5BM.

Benchmark Performance

The benchmark data for this processor is minimal. The benchmarks array is empty, and the average benchmark score is recorded as 0. The percentileVsAllCpus field places it at the 50th percentile, meaning it sits exactly at the midpoint of the distribution of all CPUs in the database. This is a neutral position, indicating that while it is not a top performer, it is not at the bottom either. The fixed 2.20 GHz clock speed, with no boost clock, means that performance is consistent across workloads, but also that there is no headroom for bursty tasks. With only a single core and a single thread, the processor is limited to executing one instruction stream at a time. The 128 KB L1 cache and 1 MB L2 cache provide modest on-die storage, which helps mitigate the latency of main memory access. The dual-channel memory bus suggests that memory bandwidth is a consideration, though the exact bandwidth is not specified. The absence of any rival delta data in the nearestRivals field means that no direct percentage comparisons can be made against other processors. The 50th percentile ranking is the only positional indicator available, and it suggests that the processor is an average performer within the database's historical context. The 90 nm process node and 106 million transistor count are consistent with the mid-2000s era, and the lack of a boost clock implies that the processor runs at a constant frequency, which is typical for server parts prioritizing stability over peak speed. The average benchmark score of 0 is an artifact of the empty benchmarks array, meaning no meaningful performance data has been recorded. The single-threaded nature of this processor means that its performance is entirely dependent on its 2.20 GHz clock speed and the efficiency of the K8 architecture.

Power and Thermals

The thermal design power (TDP) is rated at 55 W, which classifies this processor as a low-power unit for its server/workstation market segment. This is a relatively modest power envelope, especially when compared to higher-end server processors that typically demand more power. The 90 nm process node, with 106 million transistors, is an older fabrication technology, but the 55 W TDP suggests that the design is tuned for efficiency rather than raw performance. The absence of a boost clock means that the power draw is steady and predictable, as the processor does not dynamically increase its frequency. This predictability is advantageous for thermal management in dense server environments. The data does not specify a cooling solution, but the 55 W TDP implies that a standard air cooler would be sufficient, as the heat output is limited. The locked multiplier (multiplierUnlocked: false) means that users cannot overclock the processor to increase performance, which also keeps thermal and power characteristics within the specified envelope. The end-of-life status suggests that this processor is no longer in active production, but its power characteristics remain relevant for historical analysis. The 55 W figure is a critical specification, as it dictates the required power delivery and thermal dissipation capabilities of the host system. The 90 nm process node, while older, was a mature technology at the time of release. The transistor count of 106 million is a fixed design parameter. The absence of a boost clock means that the processor does not have a turbo mode, so the power draw remains constant under load, which is beneficial for power budgeting in a server rack.

How It Compares

The nearestRivals field is empty in the FACT PACK, so there are no direct rival processors with associated scores or deltaPct values to compare against. Consequently, the analysis must rely on the percentileVsAllCpus value of 50. This places the Opteron 848 HE at the median of all CPUs in the database. A 50th percentile ranking means that half of the CPUs in the database perform better and half perform worse, based on the aggregated benchmark data. Without specific rival data, the single-core design is a clear differentiator, as modern processors typically feature multiple cores. The 1 MB L2 cache is substantial for a single-core part, which may help in workloads that benefit from a larger cache. The dual-channel memory bus provides a balanced memory interface, though the lack of ECC support (eccMemory: false) is a notable limitation for server applications where error correction is critical. The PCIe Gen 2 interface is an older standard, but it is present, allowing for expansion cards. The 2.20 GHz base clock is moderate, and the absence of a boost clock means it cannot exceed this frequency. In the absence of rival data, the processor's position is defined solely by its percentile ranking and its architectural specifications. The empty nearestRivals field is a limitation of the data, but it also indicates that the processor does not have any close competitors in the current database that have been explicitly linked. The 50th percentile is a broad indicator, and it suggests that the processor is not a performance outlier. The single-core design is a significant factor, as most server workloads today are multi-threaded.

Platform and Compatibility

The AMD Opteron 848 HE is built for the AMD Socket 940, which is a server-oriented socket. The platform is based on the K8 architecture with the Athens codename. Memory support is provided through a dual-channel memory bus, though the specific memory types are not listed in the data. The memory bus configuration suggests that the processor can access memory through two channels, which can improve bandwidth over a single-channel design. The PCIe interface is Gen 2, which is an older but functional standard for connecting expansion devices. The processor does not include integrated graphics, as indicated by the null integratedGraphics field. The ECC memory support is false, which is a significant compatibility consideration for server workloads that typically rely on ECC to prevent data corruption. The multiplier is locked, so the processor operates at its specified 2.20 GHz without user adjustment. The production status is end-of-life, meaning that it is no longer manufactured. The release date is February 2005. The part number is OSK848FAA5BM. The upgrade path for this processor is inherently limited to the Socket 940 platform, which is itself an older platform. The absence of a boost clock and the locked multiplier mean that there is no overclocking headroom. The 90 nm process node and 106 million transistors are fixed attributes of the design. The dual-channel memory bus and PCIe Gen 2 are the primary expansion and memory interfaces. For a server/workstation platform, the lack of ECC support is a notable drawback, as error correction is often required in mission-critical environments. The processor's 55 W TDP makes it suitable for power-conscious server deployments, but the single-core design limits its applicability to modern multi-threaded workloads. The end-of-life status indicates that replacement parts may be difficult to source, and the Socket 940 platform is no longer a current standard. Overall, the platform is a legacy server configuration with specific limitations in memory error handling and multi-core performance.
