AMD Sempron 145

The AMD Sempron 145 is a single-core, single-thread desktop processor built on the K10 architecture (codenamed Sargas) for the AMD Socket AM3 platform. With a 2.80 GHz base clock, 1 MB of L2 cache, and a 45W TDP, this end-of-life chip targets the most basic entry-level computing tasks, though its benchmark data is currently limited.

Benchmark Performance

The FACT PACK provides no benchmark scores for the AMD Sempron 145, and its nearestRivals list is empty. The avgBenchmarkScore is listed as 0, which reflects the absence of collected performance data rather than a literal performance measurement. The percentileVsAllCpus field shows a 50th percentile ranking, placing this processor at the midpoint of the database's CPU distribution — but this figure must be interpreted cautiously given the lack of direct scores.

Without benchmark numbers, the data indicates that the Sempron 145's performance cannot be quantitatively compared to any rival at this time. The single core and single thread configuration, combined with the 2.80 GHz clock speed, suggests the processor is designed for basic computational throughput rather than competitive multi-core workloads. The 128 KB L1 cache and 1 MB L2 cache per core are modest figures that align with the processor's entry-level positioning.

The absence of a boost clock means the 2.80 GHz is the maximum sustained frequency — there is no dynamic overclocking headroom from the factory. This static clock speed, paired with a single execution thread, limits the processor to workloads that are inherently serial and lightweight. In the broader database context, the 50th percentile ranking implies this chip sits at the median of all CPUs tracked, though this is a positional metric without supporting score data to validate it.

Single-Thread vs Multi-Thread Behavior

The Sempron 145 is a pure single-threaded processor: 1 core, 1 thread, no simultaneous multithreading. This means the chip can execute exactly one instruction stream at a time. For any workload that can utilize multiple threads — modern operating system background tasks, web browsers with multiple tabs, or content creation software — the processor will time-slice between tasks rather than parallelize them.

The 2.80 GHz clock speed is the sole determinant of single-thread performance, and with no boost clock, this frequency is constant under load. The 1 MB L2 cache is the primary data buffer for the single core, and at 45 nm process node with 234 million transistors on a 117 mm² die, the architecture is mature but dated compared to later multi-core designs.

In real-world terms, the single-thread behavior means the processor handles one active application at a time with reasonable responsiveness, but any multitasking will cause significant context-switching overhead. The data shows no multi-thread capability whatsoever, so the split between single-thread and multi-thread performance is absolute: the chip is 100% single-thread, with zero multi-thread execution capacity.

Who Should Consider It

Given the benchmark data is unavailable, workload recommendations must be inferred from the architectural specifications. The single core and single thread configuration makes this processor suitable only for the most basic computing tasks: text editing, simple spreadsheet work, or lightweight web browsing with a single tab open. For gaming, the lack of multi-threading and the modest 2.80 GHz clock will severely limit performance in any modern title, which typically requires multiple cores.

For content creation — video editing, 3D rendering, or large-scale photo processing — the Sempron 145 is not viable; these workloads are heavily multi-threaded and would overwhelm the single core. Office productivity is marginal: single-document word processing or email checking would work, but any concurrent background activity (antivirus scans, system updates) will degrade responsiveness noticeably.

The 45W TDP and 45 nm process suggest a low-power, low-heat design, which could suit a basic home server for file sharing or a lightweight point-of-sale terminal. The DDR3 dual-channel memory support and PCIe Gen 2 connectivity are adequate for these basic roles. However, the end-of-life production status means no new system builds should target this chip, and the absence of a launch MSRP means no cost-based evaluation is possible from the data.

How It Compares

The nearestRivals list is empty in the FACT PACK, so no direct comparative analysis against specific competitors is possible. The percentileVsAllCpus field at 50% indicates a median position among all CPUs in the database, but without named rivals, no deltaPct values or score comparisons can be stated.

Attempting to position the Sempron 145 against other processors would require speculating on rival performance, which the data does not support. The only factual statement is that this processor has no listed rivals, meaning the database currently contains no comparable CPUs with sufficient benchmark data to establish a competitive relationship.

Power and Thermals

The TDP (Thermal Design Power) is rated at 45W, which places this processor in the low-power class for desktop CPUs. This 45W figure indicates the maximum heat the cooling system must dissipate under sustained load. For cooling, this implies a basic air cooler is sufficient — a small aluminum heatsink with a quiet fan would handle the thermal load without difficulty.

The 45 nm process node contributes to this modest power draw; smaller process nodes typically reduce both power consumption and heat output, though 45 nm is an older fabrication technology compared to more recent nodes. The die size of 117 mm² and 234 million transistors are consistent with the power envelope. No boost clock means power draw is steady at the 2.80 GHz operating point, with no transient spikes from frequency ramping.

For system builders, the 45W TDP means a standard entry-level power supply is adequate, and the low heat output allows for compact or passively cooled cases in theory, though the data does not specify cooler requirements beyond the implied wattage class.

FAQ

Q: What is the core and thread count of the AMD Sempron 145?

A: The processor has 1 core and 1 thread, making it a strictly single-threaded design.

Q: Does the Sempron 145 have a boost clock?

A: No, the boostClock field is null; the base clock of 2.80 GHz is the maximum and only operating frequency.

Q: What memory type does this processor support?

A: It supports DDR3 memory in a dual-channel configuration, and ECC memory is not supported.

Q: Is the multiplier unlocked for overclocking?

A: No, the multiplierUnlocked field is false, so the clock multiplier cannot be adjusted.

Q: What PCIe generation is supported?

A: The processor supports PCIe Gen 2, which is the second generation of PCI Express.

Q: What is the production status of the Sempron 145?

A: The productionStatus is end-of-life, and the release date is 2010-08-31, indicating the chip is discontinued.

Platform and Compatibility

The AMD Sempron 145 uses the AMD Socket AM3, which is compatible with AMD's K10 architecture family. The socket supports DDR3 memory in a dual-channel configuration, with no ECC support. PCIe Gen 2 is the available expansion interface for graphics cards or other add-in cards.

The processor does not include integrated graphics; the FACT PACK notes that graphics are available "on certain motherboards (Chipset feature)", meaning the display output depends on the motherboard's integrated chipset graphics rather than the CPU itself. This is an important distinction for system builders — a discrete graphics card or a motherboard with integrated graphics is required for display output.

The 45 nm process node and 234 million transistors on a 117 mm² die are the physical specifications. The architecture is K10, codenamed Sargas, which is part of the Sempron generation. The upgrade path is limited by the end-of-life status and the AM3 socket, which supports other AM3 processors but the data does not specify which ones. The part number SDX145HBK13GMSDX145HBGMBOX identifies the specific SKU.

The memory bus is dual-channel DDR3, but the memory bandwidth is not specified in the data. The L3 cache is null, meaning no L3 cache is present — only the 128 KB L1 and 1 MB L2 per core. This cache configuration is modest but consistent with the single-core design. The lack of an L3 cache, combined with the single thread, makes this processor best suited for legacy systems or very basic computing tasks where platform simplicity outweighs performance.
