AMD Opteron X2 175

The AMD Opteron X2 175 is a dual-core K8 processor from the Denmark generation, built for AMD Socket 939 and aimed at the Server/Workstation segment. It has 2 cores and 2 threads, with a base clock of 2.20 GHz and no listed boost clock. The design uses a 90 nm process, comprises 233 million transistors, and occupies a 199 mm² die. Each core is equipped with 128 KB of L1 cache and 1 MB of L2 cache; no L3 cache appears in the record. Memory support is dual-channel DDR1 with a bandwidth rating of 6400 MB/s, and ECC memory is not listed as supported. The part number is OSA175DAA6CD, it was released on 2005-08-01, is marked end-of-life, and its launch MSRP was $530.

Single-Thread vs Multi-Thread Behavior

With 2 cores and 2 threads, the Opteron X2 175 presents no logical processors beyond its physical cores. Each thread maps to a dedicated core, so there is no sharing of execution resources between extra logical threads. For single-thread workloads, the relevant variables are the 2.20 GHz base clock and the private cache structure: 128 KB of L1 per core and 1 MB of L2 per core. The absence of a boost clock means the data does not describe any temporary frequency increase above the base value. The multiplier is also locked, so the only operating frequency given is the fixed 2.20 GHz figure.

The multi-thread profile is therefore a pure two-core profile. Workloads that split cleanly into two threads can use both cores at their listed base clock. Workloads with more than two runnable threads have no extra execution contexts and will time-slice on the same two cores. This makes the processor’s multi-thread behavior simple to characterize at the structural level, but the database contains no benchmark runs to say how that translates into numerical performance. The benchmark array is empty, and the average benchmark score field is 0. The split between single-thread and multi-thread behavior is thus defined by core count and cache capacity rather than by measured scores.

Memory behavior also shapes both modes. A dual-channel DDR1 interface rated at 6400 MB/s is the system memory ceiling. In single-thread workloads, per-core L1 and L2 caches can absorb much of the data locality. In two-thread workloads, both cores contend for the same dual-channel memory interface when their caches miss. The lack of L3 means any miss from L1 or L2 must be satisfied from DDR1 memory, so memory-bound tasks are constrained by the 6400 MB/s bandwidth and the DDR1 generation. Because the record does not contain performance data, the exact penalty of crossing from two threads to heavier thread counts cannot be quantified from this page alone.

Power and Thermals

The governing power figure in the record is a TDP of 110 W. This places the processor in a 110 W thermal class. A cooling solution used with this socket and platform must be capable of moving that design-level heat load under sustained operation. The physical context for the 110 W envelope comes from the 90 nm process, the 233-million-transistor count, and the 199 mm² die size. Those figures describe a dual-core K8 die of relatively substantial area for its era, and the TDP reflects the power expected from two cores at 2.20 GHz.

The thermal record is otherwise short. No boost clock is listed, so the frequency is not stated to vary above 2.20 GHz. There is no idle power, load power, or efficiency figure beyond the 110 W TDP. The locked multiplier means the user cannot raise the frequency through a multiplier change in the documented data. From a cooling standpoint, the important implication is that the platform must be designed for a 110 W part. The server/workstation market segment is the stated context for this processor, but the data itself does not specify cooler height, airflow, or acoustic limits.

Benchmark Performance

The benchmark section of this record is empty. There are no individual entries in the benchmarks array, and the average benchmark score field stores 0. That means there is no measured score on this page from which to derive workload-based throughput. The nearestRivals list is also empty, so no rival CPU names and no deltaPct values are available for comparison. In the absence of those entries, no exact percentage lead or deficit can be calculated for the Opteron X2 175 relative to other CPUs.

The only placement metric present is percentileVsAllCpus, with a value of 50. In a database-wide ordering, the Opteron X2 175 sits at the 50th percentile. That is not a workload score; it is a position relative to all other CPU records in the database. The value implies that the aggregate index places the processor exactly at the median of the distribution. Because the benchmark arrays are empty, this percentile should be read as the record’s global position rather than as a measured performance result.

Without nearestRivals entries, there are no reference points for exact percentage deltas. The database provides the processor’s structural specifications, but it does not support an evidence-based comparison against alternative CPUs. The empty benchmark field also means the 50th percentile should not be mistaken for a validated speed ranking. Any statement about performance beyond the basic clock, cache, and memory bandwidth structure of the part cannot be grounded in the data on this page.

FAQ

Q: How many cores and threads does the Opteron X2 175 have?

A: It has 2 cores and 2 threads, so it does not add extra logical processors beyond the physical cores.

Q: What memory type and configuration are supported?

A: The memory support field lists DDR1 memory in a dual-channel configuration, with memory bandwidth rated at 6400 MB/s.

Q: Does it support ECC memory?

A: The record lists ECC memory as false, so ECC memory support is not indicated for this part.

Q: Is the processor multiplier unlocked?

A: No. The multiplierUnlocked field is false, and no boost clock is listed; the base clock is 2.20 GHz.

Q: What is the cache arrangement?

A: Each core has 128 KB of L1 cache and 1 MB of L2 cache. No L3 cache is listed.

Q: When was it released and what is its production status?

A: The release date is 2005-08-01, and the production status is end-of-life.

Who Should Consider It

Based on the data, the Opteron X2 175 is a two-thread processor. Software that runs one or two active threads is the only workload profile that can use the full core count. The server/workstation market segment and the Socket 939 platform suggest maintenance or replacement of an existing dual-core server or workstation board. The 1 MB L2 cache per core is useful for workloads where per-core cache locality matters. The dual-channel DDR1 interface at 6400 MB/s is a clear ceiling for memory-heavy tasks, and the absence of ECC support is relevant for any server or workstation role that expects error-corrected memory.

For gaming, the record does not list a processor-local GPU. The integrated graphics field says “On certain motherboards (Chipset feature),” so display output is a platform/chipset characteristic rather than a CPU capability. With only 2 cores and 2 threads, game workloads that scale beyond two threads would have no additional cores to use. The lack of benchmark scores means no specific gaming performance claim is supported by this page.

For content creation, the limiting factors are core count and memory bandwidth. Many creation tools can use more than two threads, and this processor provides exactly 2 threads in total. The 6400 MB/s memory bandwidth also constrains data-heavy editing or rendering workloads. It is more naturally suited to lightly threaded office or administrative tasks, where two full K8 cores at 2.20 GHz with private L2 caches are a reasonable structural match. Even in that context, any workload that grows beyond two runnable threads will be placed on the same two cores. The 50th percentile database position suggests a mid-table placement, but the empty benchmark data means that placement is not a measured performance verdict.
