AMD A4 Micro-6400T

AMD A4 Micro-6400T

The AMD A4 Micro-6400T is a mobile quad-core SoC (codenamed "Mullins") for tablets, which has been presented in April 2014. In addition to 4 CPU cores clocked at 1.0 - 1.6 GHz (boost clock), the 28 nanometer chip also integrates a Radeon R3 GPU, a single-channel DDR3L-1333 memory controller and the Southbridge with various I/O-ports.

Architecture

Both 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

In single thread tasks, the APU should be even faster than the former A4-5000 (15 W, 1.5 GHz), but clocks and performance may decrease substantially in long-lasting multi-thread benchmarks. Nonetheless, the Micro-6400T should be sufficient for simple workloads like Office, Internet browsing and multimedia.

Graphics

The SoC integrates a Radeon R3 GPU with 128 shaders, which is based on the GCN architecture and clocked at up to 350 MHz. On average, we expect the graphics performance to be similar to Intel's HD Graphics (Ivy Bridge) or a Radeon HD 8250. Current games (as of 2014) are thus hardly playable even in low settings, only a few older and less demanding titels should run fluently.

Power Consumption

The power consumption of the entire SoC is rated at 4.5 watts TDP (SDP: 2.8 W). Thus, the APU is suitable for passively cooled tablets.
