The AMD A6-7310 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 2.4 GHz (boost clock), the 28 nanometer chip also integrates a Radeon R4 GPU, a single-channel DDR3L-1600 memory controller and the southbridge with various I/O-ports. The TDP of the A6-7310 can be configured from 12 to 25 Watt. The predecessor AMD A6-6310 features similar specifications except maybe a changed base clock, the configurable TDP, and the new FP4 package (compatible to the mainstream Carrizo SoCs). The top model A8-7410 of Carrizo-L in comparison clocks 100 MHz higher and supports DDR3L-1866.
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 slightly faster than the old A6-6310 and therefore similar performance to a Haswell-based Pentium or ULV Core i3.
Graphics
The integrated Radeon R4 should be similar to the Beema based Radeon R4 GPU with 128 shaders. Only a few current games (as of 2014) are thus playable in low settings, but older and less demanding titels should run flawlessly.
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.
