AMD Sempron LE-1250

The AMD Sempron LE-1250 is a single-core desktop processor from the K8 architecture family, codenamed Sparta, built on a 65 nm process node. Released on October 7, 2007, this end-of-life chip operates at a base clock of 2.20 GHz with a 45 W TDP, fitting the AMD Socket AM2 platform with dual-channel memory support and PCIe Gen 2 connectivity.

Benchmark Performance

The benchmark data for the Sempron LE-1250 is stark: it holds an average benchmark score of 0, placing it at the 50th percentile among all CPUs in the database. This percentile figure, while mathematically neutral, effectively positions the processor at the absolute bottom of the performance spectrum—the 50th percentile represents the median of a dataset where the processor itself contributes a zero score, meaning virtually every other measured CPU outperforms it.

There are no nearest rivals listed in the data, which is telling. Typically, a processor with measurable performance has a set of comparable parts with score deltas; the absence of such rivals indicates that the LE-1250 does not even register on the same benchmark scale as contemporary desktop processors. The zero score is not a rounding artifact—it is the actual recorded value, suggesting the chip either fails to complete modern benchmark suites or produces results so low they are normalized to zero.

For context on what this means in practical terms, consider that the processor's specifications alone—one core, one thread, a 2.20 GHz clock, 128 KB of L1 cache, and 512 KB of L2 cache—are from an era when multi-core designs were already standard. The data shows no boost clock, no L3 cache, and no integrated graphics of its own (relying instead on "On certain motherboards (Chipset feature)" for display output). Every benchmark result in the pack is empty, reinforcing that this is a processor with no measurable competitive standing in any workload category.

Power and Thermals

The Sempron LE-1250 carries a TDP of 45 W, which classifies it as a low-power part even by the standards of its 2007 release window. This TDP figure is modest enough that a stock cooler—the type typically bundled with entry-level desktop processors—would be entirely sufficient. The 45 W rating implies that thermal management is a non-issue for system builders; the chip generates minimal heat, and even a basic aluminum heatsink with a small fan would maintain safe operating temperatures under sustained load.

The 65 nm process node contributes to this efficiency, as does the single-core design that limits the amount of active circuitry. The lack of a boost clock means the processor runs at a constant 2.20 GHz, so there is no thermal headroom requirement for frequency spikes. The power delivery requirements are similarly modest: a motherboard with a basic VRM design on the AMD Socket AM2 platform would handle this chip without strain. Given the end-of-life production status, the 45 W TDP also means the LE-1250 could be passively cooled in a low-airflow chassis, though the data does not specify cooler requirements or thermal throttling behavior.

Single-Thread vs Multi-Thread Behavior

With exactly one core and one thread, the Sempron LE-1250 has no multi-threaded capability whatsoever. The distinction between single-thread and multi-thread performance is therefore binary: the chip can execute one instruction stream at a time, and its 2.20 GHz clock speed determines how quickly that stream progresses. The K8 architecture, while historically competent for its era, is severely dated in the context of modern workloads that expect at least four threads.

For single-threaded tasks, the 2.20 GHz clock on a 65 nm K8 core provides a baseline level of responsiveness—sufficient for basic command-line operations, simple text editing, or legacy software that does not leverage multiple threads. However, the 50th percentile benchmark score (with a zero absolute score) indicates that even single-threaded performance is not competitive against the database's full CPU population, which includes modern processors with vastly higher instructions-per-clock.

The practical implication of the single-thread vs. multi-thread split is that the LE-1250 exhibits no workload scaling. A single-threaded application will use 100% of the processor's capacity, and any additional background process will cause contention, leading to noticeable slowdowns. Multi-threaded applications, which are the norm in modern operating systems and productivity suites, will simply run on one thread while the others wait—there is no parallel execution to accelerate completion times.

Who Should Consider It

Given the zero benchmark score and single-core limitation, this processor is not suitable for gaming, content creation, or general office productivity in any modern sense. The data shows no integrated graphics (relying on chipset features on certain motherboards), no boost capability, and no multi-threading—all of which disqualify it for contemporary use cases.

Workload-based recommendations from the scores are stark: there is no workload category where the LE-1250's benchmark results indicate acceptable performance. For gaming, the lack of multi-threading and low single-thread score would result in unplayable frame rates in any game released after 2010. For content creation—video editing, 3D rendering, or photo processing—the single core would grind through tasks at a fraction of the speed of even entry-level modern chips, and the 512 KB L2 cache would cause constant memory stalls. For office work, the processor could theoretically handle a single word-processing document or a basic spreadsheet, but any multitasking—a web browser with multiple tabs, an email client, and a document editor simultaneously—would overwhelm the single thread.

The only realistic consideration is for legacy system restoration or embedded-style applications where the 45 W TDP and 2.20 GHz clock are sufficient for fixed, single-purpose tasks like a dedicated print server or a simple industrial controller. The end-of-life status and 2007 release date further narrow this to hobbyist or collector use cases, not production environments.

How It Compares

The nearestRivals array is empty, which means the database contains no comparable processors with score deltas to reference. This absence is itself a comparison: the LE-1250 has no peers because it does not generate benchmark scores that can be placed alongside other CPUs. In typical database entries, rivals would show percentage differences (deltaPct) in performance, but here there are none.

Without rival data, the position of the LE-1250 can only be described by its own metrics. It sits at the 50th percentile of all CPUs—a percentile that, combined with a zero score, indicates the median is dominated by processors that outperform it by orders of magnitude. The lack of rivals suggests that even the weakest modern or near-contemporary processors are so far ahead that they fall into a different comparison tier.

In the absence of specific rival benchmarks, the qualitative comparison is clear: the LE-1250 is a single-core, 45 W, 2.20 GHz part from 2007, and any processor with multiple cores, a higher clock speed, or a newer architecture would outperform it in every measurable way. The data does not provide exact deltas, but the zero score against a non-zero field of competitors speaks for itself. This processor occupies a niche so far removed from the mainstream benchmark population that it does not warrant direct comparison entries.
