AMD Opteron X2 860 HE

The AMD Opteron X2 860 HE is a dual-core server processor from the K8 architecture, released in July 2005 as part of the Egypt generation. It operates at a fixed 1.6 GHz base clock with no boost capability, and its 55W TDP classifies it as a low-power part for its era. With a 50th percentile ranking among all CPUs in the benchmark database, this chip represents a median performer, neither a flagship nor an entry-level part. The following analysis draws exclusively from the available data, covering performance, platform compatibility, power characteristics, and its position in the broader landscape.

Benchmark Performance

The benchmark data for the Opteron X2 860 HE is sparse, with an average benchmark score of 0 and no individual benchmark entries. However, the percentile ranking of 50 provides a meaningful anchor: this processor sits exactly at the midpoint of all CPUs tracked in the database. In practical terms, that means it outperforms roughly half of the processors in the database and is outperformed by the other half. This is a typical position for a mid-generation dual-core server chip from the mid-2000s, where the market was still transitioning from single-core to multi-core designs.

The processor’s two cores and two threads, combined with a 1.6 GHz base clock, place it in the lower tier of dual-core parts. The lack of a boost clock means it cannot dynamically increase its frequency under load, so its performance ceiling is fixed. The cache hierarchy is modest: 128 KB of L1 cache and 1 MB of L2 cache, which is consistent with the K8 architecture of that period. These cache sizes are small by modern standards, but they were adequate for the server workloads of the time, which often relied on low thread counts and moderate memory bandwidth.

Because no rival scores are listed, the 50th percentile is the only quantitative performance reference. It indicates that the Opus X2 860 HE is a balanced, middle-of-the-road processor, not a high-end part for heavy compute tasks, but also not a weak performer. In a server context, this would translate to handling typical business applications, database queries, or web serving with reasonable efficiency, though it would struggle with modern multi-threaded workloads that demand many cores and high clock speeds.

Platform and Compatibility

The Opus X2 860 HE uses the AMD Socket 940, a server-oriented socket that was also used by early Opteron processors. This socket supports dual-channel memory, as indicated by the dual-channel memory bus, which doubles the memory bandwidth compared to a single-channel configuration. However, the exact memory types and speeds are not listed in the data, so we cannot specify whether it supports DDR, DDR2, or other standards. The lack of ECC memory support is notable for a server processor, as ECC is often a key feature in mission-critical environments to detect and correct memory errors. The data explicitly states that ECC memory is false, meaning this processor does not support error-correcting code memory, which may limit its appeal for certain reliability-focused deployments.

The processor is built on the K8 architecture, codenamed Egypt, and uses a 90 nm process node. It integrates 233 million transistors, a figure that reflects the complexity of the dual-core design at the time. The PCIe support is listed as Gen 2, which is a significant detail: PCIe Gen 2 offers higher bandwidth per lane than the original Gen 1, making it suitable for high-speed peripherals such as network cards or storage controllers. However, the number of PCIe lanes is not specified, so we cannot comment on the expansion capacity.

The production status is end-of-life, meaning AMD no longer manufactures or sells this processor. This has implications for upgrade paths: there is no future support for this socket, and users would need to replace the entire platform to move to a newer processor. The release date of July 2005 places it in the early days of dual-core server processors, and the end-of-life status indicates that it has been obsolete for many years. For a modern system, this processor is not a viable choice, but it remains historically interesting as an early dual-core server part.

Power and Thermals

The Opus X2 860 HE has a TDP of 55 watts, which is notably low for a server processor of its generation. This TDP class places it in the "low-power" or "energy-efficient" tier, which is a significant advantage in dense server environments where heat dissipation and power consumption are critical. A 55W TDP means that the processor can be cooled by a modest air cooler, such as a low-profile heatsink or a small tower cooler, without the need for liquid cooling or high-end thermal solutions. This is particularly beneficial for 1U or 2U rack servers, where space is limited and airflow is constrained.

The low TDP is partly a result of the 90 nm process node, which was relatively advanced at the time but still allowed for a dual-core design at a moderate clock speed. The 1.6 GHz base clock is conservative, which helps keep power draw low. The transistor count of 233 million is high for the era, but the low clock speed and efficient architecture keep the thermal output manageable. In practice, a system builder would need only a capable air cooler, not a massive heatpipe or liquid cooling solution, to keep this processor within safe temperatures.

The low TDP also has implications for the overall system power budget. In a server with multiple processors, the cumulative power draw would be lower than with higher-TDP parts, allowing for more efficient power supplies and lower operating costs. However, the end-of-life status means that these benefits are no longer relevant for new deployments, but they illustrate the design philosophy of the time: balancing performance with power efficiency.

FAQ

Q: How many cores and threads does the Opus X2 860 HE have?

A: It has 2 cores and 2 threads, meaning it can handle two threads simultaneously.

Q: What is the base clock speed?

A: The base clock is 1600.00 MHz (1.6 GHz). There is no boost clock, so it runs at this fixed speed under all conditions.

Q: What is the TDP of this processor?

A: The TDP is 55 watts, which classifies it as a low-power server processor.

Q: What socket does it use?

A: It uses the AMD Socket 940, which is a server-oriented socket.

Q: Does it support ECC memory?

A: No, the data indicates that ECC memory is not supported. This is unusual for a server processor and may limit its use in reliability-critical environments.

Q: What is the production status?

A: The production status is end-of-life, meaning it is no longer manufactured or sold.

How It Compares

The database lists no nearest rivals for the Opus X2 860 HE, so a direct comparison with specific competing processors is not possible. However, the 50th percentile ranking provides a general reference point: this processor sits exactly in the middle of all CPUs in the database, indicating that it is neither a high-end nor a low-end part. In the context of its release year, 2005, it would have competed with other dual-core server processors from AMD and Intel, but without specific rival data, we cannot quantify those differences.

The lack of boost clock and the modest 1.6 GHz base clock suggest that it would lag behind higher-clocked dual-core parts of its generation, while the 55W TDP gives it an advantage in power efficiency. The absence of ECC support is a notable drawback for a server processor, as many server workloads require ECC to ensure data integrity. In a modern context, this processor is far behind any current CPU, but its 50th percentile position in the database reflects its mid-tier status at the time of its release. Without rival scores, the only quantitative conclusion is that it is a median performer, neither a leader nor a laggard.
