Sempron LE-1300 Details

Ranking #1999 of 2060 in overall performance, the AMD Sempron LE-1300 sits near the bottom of modern benchmark comparisons, reflecting its position as a legacy processor from the late 2000s. Launched in October 2007, this CPU is part of AMD's Sempron lineup, designed for budget desktop systems. Built on a 65 nm process and based on the Sparta microarchitecture, the Sempron LE-1300 was positioned as an entry-level option for basic computing tasks during its era. Despite its age, it remains a relevant reference point for understanding the evolution of x86 processor performance over nearly two decades.

The processor features a single core and a single thread, with a base clock of 2.3 GHz and a locked multiplier, which limits its overclocking potential. It operates at a TDP of 45 W and uses the Socket AM2 interface, a standard of its time. Memory support includes dual-channel DDR2, though the exact maximum memory capacity and bandwidth are not specified. The chip includes 512 KB of L2 cache and supports a range of instruction sets including MMX, SSE, SSE2, SSE3, and 3DNow!, but lacks SSE4 support—a notable omission for modern software compatibility.

Integrated graphics are not present on the processor itself; however, certain motherboards with compatible chipsets could provide this functionality. The Sempron LE-1300 communicates with other system components via a PCI-Express Gen 2 interface. While it does not support ECC memory or simultaneous multithreading, its design prioritized affordability and power efficiency for mainstream desktops.

In benchmark testing, the Sempron LE-1300 scores 3841 overall, with a single-core score of 3568 and a multicore score of 4251. It trails behind many modern low-power processors, such as Intel's Atom and Celeron series, and is significantly outpaced by current high-end CPUs like the Ryzen Threadripper PRO 9995WX, which scores over 9,000 in the same tests. Its performance places it among the slowest in the broader processor landscape, with only a few older mobile and embedded processors falling below it.

As of March 2026, the Sempron LE-1300 is no longer suitable for modern applications, gaming, or multitasking. Its primary use today is in legacy systems, educational demonstrations, or as a reference in historical comparisons. For users seeking a capable desktop CPU, modern alternatives offer orders of magnitude more performance, efficiency, and feature support.
