Athlon 64 X2 3800+ Benchmark Scores

About AMD Athlon 64 X2 3800+

The AMD Athlon 64 X2 3800+ is a desktop processor from AMD, built on the K8 architecture with the Windsor codename. It was released on May 22, 2006, and is now end-of-life. The database lists it at the 50th percentile of all CPUs, with an average benchmark score of 0, indicating that no performance measurements have been recorded for this part. This analysis examines its specifications, platform compatibility, and likely workload fit based on the available data.

Benchmark Performance

The benchmark performance of the Athlon 64 X2 3800+ cannot be quantified from the database because the benchmarks array is empty and the average benchmark score is 0. The 50th percentile ranking places it at the median of all CPUs in the database, but without actual scores, this percentile is not a performance indicator but a position based on the presence of the processor in the database. The processor's architectural characteristics—two cores, two threads, a 2000 MHz base clock, and no boost clock—define its computational ceiling. The L1 cache is 256 KB and the L2 cache is 512 KB, with no L3 cache. The dual-channel memory bus and PCIe Gen 2 interface are the only connectivity features. Given the absence of rival scores, no delta percentages can be computed. The data suggests that this processor is a baseline dual-core part from its era, likely intended for entry-level desktop tasks. The lack of a boost clock means it operates at a fixed 2000 MHz under all conditions, which simplifies thermal and power management. The 50th percentile ranking is the only comparative metric available, and it indicates a median standing among the database's recorded processors. However, because the average benchmark score is zero, this percentile may reflect the absence of data rather than a measured performance level. The processor's two cores and two threads allow it to handle two simultaneous threads, but the 2000 MHz clock is modest. The cache sizes are fixed: 256 KB L1 and 512 KB L2. No L3 cache is present, which may affect workloads that rely on large caches. The dual-channel memory bus provides a balanced memory interface, but the specific memory bandwidth is not listed. The PCIe Gen 2 interface is a standard for its generation, but no further details are provided. In summary, the benchmark section contains no scores to interpret; the only quantitative data are the 50th percentile and the 0 average score, which together indicate that this processor has not been tested in the database.

Who Should Consider It

Given the dual-core, dual-thread configuration and the 2000 MHz base clock, this processor is suited for basic desktop applications that do not require high thread counts. Office productivity, web browsing, and light multitasking are within its capabilities. The absence of a boost clock means it cannot dynamically increase frequency for short bursts, so workloads that benefit from single-thread performance will rely solely on the 2000 MHz clock. The dual-channel memory bus is a feature of the platform, and the processor has no integrated graphics on the CPU; a discrete graphics card or a motherboard with a graphics-capable chipset is necessary for display output. The end-of-life status suggests that it is no longer manufactured, so it may be of interest to retro computing enthusiasts or as a low-cost upgrade for legacy AM2 systems. The lack of ECC memory support makes it unsuitable for error-sensitive server or workstation environments. The processor is not multiplier unlocked, so overclocking is not a straightforward option. Based on the data, it is not recommended for workloads that demand more than two threads or higher clock speeds, as the fixed 2000 MHz and two-thread limit are the only performance parameters available. The 50th percentile ranking, while not a performance metric, places it in the middle of the database's CPU population, which may suggest a typical entry-level desktop processor. Users who require a simple, low-power system for basic tasks could consider this part, provided they have a compatible AM2 motherboard and a discrete GPU. The lack of a boost clock and the modest cache sizes (256 KB L1, 512 KB L2) further define its target use case as lightweight, single-application or light multitasking scenarios.

Platform and Compatibility

The Athlon 64 X2 3800+ is designed for the AMD Socket AM2 platform. It supports dual-channel memory, but the specific memory types are not listed in the database. ECC memory is not supported, so only non-ECC modules are compatible. The processor provides PCIe Gen 2 connectivity, which is a standard for its generation. Integrated graphics are not included on the CPU; they are only available on certain motherboards via the chipset. This means that a system based on this processor requires a discrete GPU or a motherboard with an integrated graphics controller. The processor is not multiplier unlocked, so its clock multiplier is fixed. The production status is end-of-life, indicating that AMD no longer manufactures this part. The release date of May 22, 2006, defines the platform's age. The part number is ADA3800IAA5CU. There is no information on memory bandwidth or maximum memory capacity in the database. The upgrade path within the AM2 socket is not documented in the provided data, so no conclusions can be drawn about compatibility with other AM2 processors. The lack of an L3 cache and the fixed 2000 MHz clock are key characteristics of this platform. The process node is 90 nm, with a die size of 220 mm² and a transistor count of 154 million, which are physical attributes of the chip. The socket AM2 is a fixed interface; the processor's end-of-life status means that new units are not available. The dual-channel memory bus is the only memory feature listed; no ECC support narrows the memory module options. The PCIe Gen 2 interface allows for standard expansion cards, but the number of lanes is not specified. The integrated graphics capability is delegated to the chipset, which means the motherboard choice is critical for display output. Overall, the platform is a legacy AM2 setup with limited modern expansion options, but it is consistent with the processor's 2006 release.

Power and Thermals

The Athlon 64 X2 3800+ has a thermal design power (TDP) of 89 W. This value indicates the maximum amount of heat the cooling system must dissipate under typical load. The processor is built on a 90 nm process node, with a die size of 220 mm² and a transistor count of 154 million. These physical characteristics influence the thermal density. Since there is no boost clock, the power draw is relatively constant at the base 2000 MHz frequency. The 89 W TDP is a specific value that dictates the cooling requirement. A capable air cooler should be sufficient to keep temperatures within operating limits, but the exact cooling solution is not specified in the database. The lack of an unlocked multiplier means that power consumption cannot be easily adjusted through overclocking. The end-of-life status suggests that replacement parts may be scarce. The process node and die size are fixed attributes that determine the thermal behavior. No additional power or thermal metrics are provided. The 89 W TDP, combined with the 90 nm process, implies a certain heat dissipation profile, but without comparative data, no conclusions about efficiency can be drawn. The fixed 2000 MHz clock and the absence of a boost mechanism mean that the processor does not experience frequency-dependent power spikes. The thermal solution must be designed to handle a continuous 89 W load. Given that the processor is from 2006, cooling solutions of that era were typically sufficient for this TDP class. The dual-channel memory bus and PCIe Gen 2 interface do not directly affect thermal output, but they are part of the overall system power budget. In summary, the 89 W TDP is the key thermal parameter, and the 90 nm process with 154 million transistors and a 220 mm² die size are the physical factors that define the heat generation.
