C-70 Details

As of March 2026, the AMD C-70 remains a relic from an earlier era of mobile computing, having been launched in September 2012. Built on AMD’s 40 nm process and based on the Ontario microarchitecture, this processor was designed for low-power mobile devices where efficiency and integrated graphics were prioritized over raw performance. With a 9 W TDP and a single-core, single-threaded design, the C-70 reflects a time when power efficiency and thermal constraints dictated performance trade-offs.

The C-70 features a base clock of 1000 MHz, with a turbo frequency reaching 1333 MHz under load, though its performance is constrained by its dual-core design and limited cache hierarchy. Each core has 512 KB of L2 cache, totaling 1.024 MiB across both cores, while L1 cache is listed at 0.061 MiB. It supports DDR3 memory via a single-channel interface and operates on the Socket FT1 platform, which is now obsolete in modern systems. Despite its age, the processor includes support for modern features such as MMX, SSE, SSE2, SSE3, SSSE3, SSE4a, and AMD-V, enabling basic virtualization and multimedia acceleration.

Integrated graphics are provided by the Radeon HD 6290, which offers modest performance suitable for light multimedia playback and basic desktop tasks. However, it lacks the compute power needed for modern gaming or GPU-intensive applications. The processor's lack of simultaneous multithreading and a locked multiplier further limit its versatility, making it unsuitable for overclocking or demanding multi-threaded workloads.

Performance benchmarks place the C-70 near the bottom of the hierarchy. It scores 3829 in the overall benchmark, ranking #2005 of 2060, with a single-core score of 3568 (#1995) and a multicore score of 4220 (#1985). These results indicate that while the C-70 performs comparably to some low-end Atom and Celeron processors, it falls significantly behind contemporary CPUs in both single-threaded and multi-threaded tasks. Its closest competitors include the C-60 and Pentium N3510, but even these modern low-power chips outperform the C-70 in most metrics.

Given its age and performance profile, the C-70 is best suited for legacy systems, embedded applications, or educational purposes where minimal processing power is sufficient. It serves as a reminder of how far mobile computing has come, with today’s processors offering vastly superior performance, efficiency, and feature sets. For users seeking anything beyond basic functionality, the C-70 is no longer a viable option.
