The AMD A4-7210 is a mobile quad-core SoC (codenamed "Carrizo-L") for entry-level devices and subnotebooks, which has been presented in May 2015. In addition to 4 CPU cores clocked at up to 2.2 GHz (boost clock), the 28 nanometer chip also integrates a Radeon R3 GPU, a single-channel DDR3L-1600 memory controller and the southbridge with various I/O-ports. The TDP of the A4-7210 can be configured from 12 to 25 Watt. The predecessor AMD A4-6210 features similar specifications except the slower clock speed (at least boost), the configurable TDP, and the new FP4 package (compatible to the mainstream Carrizo SoCs).
Architecture
Carrizo-L, Beema (for notebooks) and Mullins (for tablets and compact subnotebooks, same die) are based on AMD's Puma+ architecture, which is the successor to the previous Jaguar design (Kabini and Temash APUs). Neither the performance per clock nor the feature set (including SSE up to 4.2, AVX and AES) have been modified. However, AMD managed to reduce the leakage current, enabling significantly higher (boost) clock speeds. This leads to a more responsive system and better overall performance. As its predecessor, the chip is manufactured in 28 nm.
Performance
The processor performance depends on the configured TDP of the SoC. Set to 25 Watt, the CPU should be faster than the old A6-6210.
Graphics
The integrated Radeon R3 should be similar to the Beema based Radeon R3 GPU with 128 shaders. In our first review sample the GPU was clocked at 686 MHz and therefore 86 MHz faster than in the A4-6210. Only a few current games (as of 2014) are thus playable in low settings.
Power Consumption
The power consumption of the entire SoC is rated at 12 to 25 watts. Thus, the APU is also suitable for small subnotebooks.
