AMD Opteron X2 285

The AMD Opteron X2 285 is a dual-core server/workstation processor released in 2006 for the AMD Socket 940 platform. It belongs to the K8 architecture family under the Italy codename, within the Opteron X2 (Italy) generation, and is built on a 90 nm process with 233 million transistors. The base clock is 2.60 GHz; no boost clock is recorded. The part has 2 cores and 2 threads, 128 KB of L1 cache and 1 MB of L2 cache, a dual-channel memory bus, and PCIe Gen 2 connectivity. It is listed as End-of-life. Benchmark records are empty, the average benchmark score is 0, and the all-CPU percentile is 50. No nearest rivals are recorded, so the comparison table for this processor is blank.

How It Compares

The nearestRivals array for this processor is empty. That means the database does not associate any named competitor with the Opteron X2 285, and no rival scores or deltaPct values are available to cite. The only comparative numeric in the record is the percentileVsAllCpus value of 50. On a percentile scale, a value of 50 places the part at the median of all CPUs in the database. Because the benchmark list is empty and the average benchmark score is 0, this midpoint placement is not tied to any measured workload result. The 50th percentile is the only available positional fact: a median rank with no specific rival nearby in the data set.

In records where nearest rivals exist, the deltaPct value would show how far ahead or behind this part is compared with a known alternative. Here no deltaPct value can be derived, because no alternative is listed. The absence of rival data is itself a meaningful statement about the database entry: the Opteron X2 285 is an unpaired record. The empty benchmark array reinforces that. With no scores and no nearest rivals, the comparison section contains no computed deltas and no percentage advantages or deficits.

Power and Thermals

The TDP value is 95. This is the thermal envelope that a Socket 940 heatsink, chassis airflow, and power-delivery design must handle. A 95 TDP part is not a low-power component; it requires a cooling solution rated for that TDP class. The 90 nm manufacturing process and the 233 million transistor count define the physical scale of the die, and the TDP represents the heat that those transistors can generate under load.

No boost clock is recorded, so the processor does not list a higher-frequency thermal state. The 2.60 GHz base clock is the only clock frequency in the data, meaning the sustained thermal demand is anchored to that frequency. The multiplier is not unlocked, so user-controlled clock multiplier adjustment is not available. That makes thermal validation relatively straightforward: the platform must be built for a fixed 95 TDP operating condition rather than a range of user-defined overclocked states. The dual-channel memory bus and PCIe Gen 2 interface are part of the platform electrical environment, though the TDP figure describes the processor package itself. End-of-life status does not lower the thermal requirement; installed systems still need a thermal solution suitable for the 95 TDP class.

Benchmark Performance

The benchmark data for this processor is empty. The benchmarks array contains no entries, and the average benchmark score is 0. As a result, no measured performance scores can be reported for this part. With no scores, there are no exact percentage comparisons to any other CPU. The nearestRivals list is also empty, so no deltaPct values exist to express a percentage advantage or deficit.

The only quantitative comparison signal is the percentileVsAllCpus value of 50. That value indicates a median standing in the all-CPU distribution, but because the benchmark array is empty, the percentile is not supported by any recorded benchmark run. The performance-relevant characteristics in the record are the K8 core design, 2.60 GHz base clock, 2 cores and 2 threads, 128 KB L1 cache, 1 MB L2 cache, dual-channel memory bus, and the absence of a boost clock. These are structural and functional parameters, not measured results. The database record therefore supports architectural description but does not support a numeric performance ranking for the Opteron X2 285.

Who Should Consider It

The Opteron X2 285 is classified in the Server/Workstation market segment. It has 2 cores and 2 threads, so its execution capacity is limited to exactly two software threads at a time. Workloads that fit this shape are lightly threaded server or workstation tasks from the K8 generation. A single-threaded office workload would use one core at 2.60 GHz; a second such workload could run on the other core.

For creation workloads, the dual-core layout permits two parallel execution threads. The absence of a boost clock means there is no single-thread turbo state to call upon when only one core is active. For gaming workloads, the two-core/two-thread structure can execute two-thread game logic, but the record lists no integrated graphics, so a separate display device is required for any video output. The platform includes a dual-channel memory bus and PCIe Gen 2, making it a plausible fit for Socket 940 server boards that need a dual-core processor in the installed base. ECC memory is marked false in the record, so error-correcting memory support is not listed as part of the feature set; this is a notable caveat for server deployment. The production status is End-of-life, meaning this is not a target for new system integration. It is best framed as a replacement or maintenance part for existing Socket 940 systems, rather than a processor for parallel workloads that need more than two threads.

Single-Thread vs Multi-Thread Behavior

The core count and thread count are equal: 2 cores and 2 threads. This means the processor does not expose any extra hardware threads beyond its physical cores, and there is no simultaneous-multithreading layer to hide instruction stalls. Single-thread workloads have one core at 2.60 GHz available, with no boost state to increase the clock for that single thread. The K8 cache hierarchy in the record consists of 128 KB of L1 cache and 1 MB of L2 cache, with no L3 entry listed, so the 1 MB L2 is the last on-die cache before memory.

Multi-thread workloads can use both cores, but only two threads can execute concurrently. A workload with more than two concurrent threads must wait for execution slots on those two cores. The dual-channel memory bus is the listed memory path, providing a two-lane interface between the cores and system RAM. Because the multiplier is not unlocked and no boost clock is recorded, both single-thread and multi-thread behavior are anchored to the same 2.60 GHz base clock. A measured multi-thread result would reflect two independent K8 cores at that clock, not one core running faster thanks to boost headroom. The lack of an L3 entry means cache misses exit the 1 MB L2 toward the memory controller, with the dual-channel bus handling external traffic. The processor's K8 architecture and Italy codename are the defining microarchitecture identifiers behind this dual-core, two-thread execution model.
