AMD Opteron 4230 HE

Platform and Compatibility

The AMD Opteron 4230 HE is built for the server and workstation segment, landing on the AMD Socket C32 platform. This socket is the foundation for the Valencia generation of Opteron processors, which employ the Bulldozer architecture. The chip is manufactured on a 32 nm process node at GlobalFoundries, packing 1,200 million transistors into a 315 mm² die. This is a dual-channel DDR3 memory controller implementation, with support for ECC memory—a critical feature for server reliability and data integrity. The memory bus delivers a peak bandwidth of 25.6 GB/s, which is adequate for the six-core workload profile this processor targets.

PCIe support is Gen 2, which is the expected generation for a 2011-era server platform. The processor does not include integrated graphics, so a discrete GPU or a server management controller with its own video output is required. The Socket C32 platform is a dual-socket-capable design, though this specific part is a single-processor SKU. Upgrade path considerations are limited because the platform is end-of-life, and the production status confirms this processor is no longer manufactured. The part number is OS4230OFU6KGU, and the multiplier is locked, meaning overclocking is not an option—common for server parts where stability and consistent performance are paramount. The launch MSRP is $377, which positions it in the mid-range of server processors at its release.

How It Compares

The benchmark database shows no nearest rivals for the AMD Opteron 4230 HE, which means direct comparative data against specific competing processors is not available in the current dataset. The percentile ranking places this chip at the 50th percentile among all CPUs tracked, indicating it sits exactly at the median performance level. This is a meaningful data point: half of the processors in the database perform better, and half perform worse. For a server chip from 2011, this suggests it was a mainstream performer rather than a flagship or entry-level part. Without nearest rivals, the comparison must be framed qualitatively—this is a six-core, six-thread processor with a base clock of 2.90 GHz and a boost clock of 3.70 GHz, which places it in the upper tier of its contemporary server lineup. The absence of rival scores means the data cannot support claims of being ahead of or behind specific named competitors, but the 50th percentile ranking gives a clear sense of its overall standing.

Who Should Consider It

The AMD Opteron 4230 HE is suited for workloads that benefit from six physical cores without hyper-threading. Server applications that are thread-aware and can utilize multiple cores will see the most benefit. Virtualization hosts running several light-to-medium virtual machines could leverage the six cores effectively, though the lack of SMT means each core handles one thread only. Memory-intensive workloads will be constrained by the 25.6 GB/s bandwidth and dual-channel configuration, so tasks that require high memory throughput may be better served elsewhere. Database workloads that are CPU-bound with moderate memory demands could perform adequately. For office-style server roles—file serving, print serving, domain controller duties—the six cores at 2.90 GHz base and 3.70 GHz boost provide responsive performance for concurrent user sessions. The 65 W TDP makes this an attractive option for dense server environments where power and cooling are constrained. Workstation use for single-threaded applications will not be ideal, as the architecture prioritizes multi-core throughput over single-core speed. Content creation tasks that are heavily threaded, such as video rendering, could see reasonable performance, but the dual-channel memory and lack of SMT will limit scaling compared to more modern or higher-end parts.

Benchmark Performance

The benchmark data for the AMD Opteron 4230 HE is sparse, with an average benchmark score of 0 and no individual benchmark entries. This means the database does not contain specific workload scores for this processor. However, the percentile ranking against all CPUs is 50, which provides a reference point. A 50th percentile score indicates median performance across the entire tracked population of processors. For a six-core server chip released in late 2011, this is a reasonable position—it is neither a top-tier performer nor a weak one. The absence of nearest rivals means there are no deltaPct values to report, and no direct percentage comparisons can be made to named competitors. The data shows that this processor was a middle-of-the-road option at its time. The 6 MB of L2 cache and 8 MB of shared L3 cache are consistent with the Bulldozer architecture, where paired cores share certain resources. The L1 cache is 288 KB. For database analytics, the lack of benchmark scores is a limitation, but the architecture and clock speeds provide a basis for inference. The 2.90 GHz base clock is modest, while the 3.70 GHz boost is respectable for the era. With six cores, multi-threaded workloads that can scale across cores will see better performance relative to single-threaded tasks.

Single-Thread vs Multi-Thread Behavior

The AMD Opteron 4230 HE has six cores and six threads, so there is no hyper-threading or SMT. This means each core is a single execution thread, and the processor cannot process more than six threads simultaneously. For single-threaded workloads, the performance is determined by the boost clock of 3.70 GHz, which is moderate. The Bulldozer architecture is known for having weaker single-thread performance per core compared to competing designs of the same era, because it uses a module-based design where two integer cores share certain resources like the floating-point unit. This can limit single-thread efficiency. For multi-threaded workloads, the six cores provide a solid foundation, but the lack of SMT means that each thread has dedicated core resources. The 8 MB shared L3 cache helps with data sharing across cores, which is beneficial for multi-threaded applications that operate on shared datasets. The dual-channel memory bus at 25.6 GB/s may become a bottleneck in multi-threaded scenarios that are memory-bandwidth sensitive, as six cores contending for memory can saturate the available bandwidth. In practice, this processor will excel in workloads that are CPU-bound and can use six threads without heavy memory traffic, such as batch processing, virtualization with modest VM counts, and compilation tasks. It will lag in workloads that are single-threaded or require high memory throughput. The 50th percentile ranking suggests balanced but not exceptional performance across mixed workloads.

Power and Thermals

The AMD Opteron 4230 HE carries a TDP of 65 W, which is the "HE" (High Efficiency) designation in the Opteron lineup. This is a low-power server part, significantly lower than standard server processors of its generation which often exceed 100 W. The 65 W TDP means that cooling requirements are modest—a capable air cooler with a standard server heatsink should suffice, and dense server chassis with limited airflow can accommodate this chip without issue. The 32 nm process node from GlobalFoundries contributes to the power efficiency, as does the six-core configuration at a 2.90 GHz base clock. The boost clock of 3.70 GHz will increase power draw transiently, but the TDP rating indicates sustained thermal output under typical loads. For server environments where power density is a concern, the 65 W TDP allows for higher core counts per rack unit and reduced cooling costs. The lack of integrated graphics also reduces overall system power draw. Thermal management is straightforward: standard server cooling solutions are more than adequate. The locked multiplier prevents overclocking, which also ensures that power and thermal characteristics remain within the specified envelope. This makes the Opteron 4230 HE a predictable choice for power-conscious server deployments where consistent performance per watt is a priority.
