The AMD A4-1250 is a mobile dual-core SoC for compact subnotebooks and tablets, which was presented in mid-2013. In addition to 2 CPU cores with a base clock speed of 1.0 GHz (no turbo), the 28-nanometer chip also integrates a Radeon HD 8210 GPU, a single-channel DDR3L-1333 memory controller as well as the Southbridge with various I/O- ports.
Architecture
Both Kabini (for notebooks) and Temash (tablets and compact subnotebooks) are based on AMD's new Jaguar architecture, which replaces the previous Bobcat models (e.g. the E-350). According to AMD, the performance per clock has been increased by about 15 percent. Furthermore, various modern instruction set extensions such as SSE up to version 4.2, AVX and AES are now supported. The finer 28-nanometer process from TSMC allows lower voltages and/or higher clock rates compared to Bobcat, as well as up to 4 CPU cores (Bobcat: 2 cores).
Performance
Due to the low clock speed of just 1.0 GHz, the performance is quite modest and similar to the old AMD C-60. For simple office and multimedia tasks, the A4-1250 has sufficient power; however, it will quickly reach its limits in more demanding applications and games.
Graphics
The SoC integrates a Radeon HD 8210 GPU with 128 shaders, which is based on the GCN architecture. The core is clocked at 300 MHz (no turbo). On average, the HD 8210 matches the Intel HD Graphics (Ivy Bridge); however, the performance is often limited by the CPU. Recent Games (as of 2013) are therefore hardly playable. Only a few older and less demanding games will run fluently.
Power Consumption
The power consumption of the entire SoC is rated at 9 watts. Thus, the A4-1250 is suitable for slim subnotebooks and tablets.
