Sempron 145 Details

The AMD Sempron 145, launched in 2010, represents a low-end desktop processor from a bygone era of computing. While it may not compete with today’s high-performance CPUs, its benchmark performance offers insight into its place in the historical landscape. As of March 2026, the Sempron 145 holds an Overall Score of 4214, placing it at #1653 among 2060 processors, with a Singlecore Score of 4188 (#1591) and a Multicore Score of 4254 (#1892). These figures reveal a processor that, while modest, holds its own against a number of modern low-power and budget chips. Its performance is comparable to older Intel Atom and Celeron models, though it trails behind most contemporary mobile and desktop processors, particularly in the single-core domain where modern CPUs like the Core Ultra 9 285K score over double its value.

The Sempron 145 is built on AMD’s Sargas architecture and features a single core with no simultaneous multithreading, operating at a base frequency of 1.3 GHz and a turbo frequency of 1.86 GHz. It uses a 32 nm manufacturing process and includes 1 MB of L2 cache, which is relatively generous for a budget processor of its time. Despite its age, it supports DDR3 memory at speeds up to 1333 MHz, with dual-channel memory bandwidth capped at 21.3 GB/s. The processor operates at a TDP of 17 W, indicating a focus on power efficiency, and is designed for socket FCBGA1170, commonly used in mobile and embedded systems. Its integrated graphics are not native to the CPU but rely on chipset support, with the HD Graphics 3000 GPU running at up to 950 MHz in burst mode and supporting up to two displays.

While the Sempron 145 lacks modern features such as AVX2, AES-NI, or PCIe 3.0/4.0, it does support a broad range of legacy instructions including MMX, SSE, SSE2, SSE3, SSE4.1, SSE4.2, and 3DNow! It also supports virtualization technologies like AMD-V, which enhances performance in virtualized environments. However, its single-core design and limited cache make it unsuitable for modern multitasking or content creation workloads. Its primary use case today would be in legacy systems or embedded applications where power efficiency and cost are more critical than raw performance.

In terms of competitive positioning, the Sempron 145 falls between older dual-core processors like the Core 2 Duo T8100 and newer low-power chips such as the Celeron N4100. It is faster than some Atom and Celeron models but is outpaced by nearly all modern processors, especially in single-core performance, where it ranks behind most CPUs launched since 2015. Its multicore score is slightly higher than some low-end dual-core designs, but this is largely due to its higher clock speed rather than architectural advantages.

In conclusion, the AMD Sempron 145 serves as a historical benchmark of early 2010s desktop computing. While it is no longer suitable for mainstream computing, it remains relevant in niche scenarios requiring low power consumption and basic processing capabilities. For users seeking modern performance, even budget processors like the Intel Celeron J3160 offer significantly better performance and features. As of March 2026, the Sempron 145 stands as a relic of an earlier era, best suited for retro computing or legacy system maintenance rather than contemporary use.
