AMD A6-4400M "Trinity" CPU sighted in HP laptop

Later this year AMD is going to introduce "Trinity" processors, that utilize enhanced Bulldozer micro-architecture, codenamed "Piledriver". New processors will be released for both desktop and mobile markets, and we already know specifications of several desktop Trinity parts. First details of mobile Trinity CPUs were revealed in February, when Arctic announced MC101 HTPC. The Arctic MC101 system will come with quad-core A8-4500M and A10-4600M SKUs, which integrate HD 7640G and HD 7660G graphics. The frequencies of these quad-core CPUs were not disclosed. Third Trinity-based mobile microprocessor recently appeared in specifications of HP g4-2002ax and g4-2003ax notebooks. The new part has model number A6-4400M.

The g4-2002ax/g4-2003ax specifications pages are light on CPU details. Nevertheless, they state that the A6-4400M has two CPU cores, and uses HD 7520G integrated GPU. The processor is paired with AMD A70M chipset, and supports at least DDR3-1600 memory. The A6-4400M runs at "2.6 GHz, 3 GHz", which we interpret as 2.6 GHz base frequency, and 3 GHz Turbo Core frequency. This frequencies are 18% and 15% higher than on the fastest production dual-core mobile A4-3330MX SKU. Bulldozer core was less efficient than K10, and it remains to be seen whether upcoming Piledriver core will match raw CPU performance of Llano chips, or not. With 15% - 20% higher clock speeds, and possibly lower efficiency, we shouldn't expect "Trinity" to perform much faster in basic applications than current generation of Llano processors. However, multimedia and data security applications will perform much better owing to new AES and AVX instructions, and games will benefit from faster HD 76xxG graphics.

Based on high clock frequency, we suspect that the A6-4400M CPU will fit into 35 Watt thermal envelope. Other CPU features, such as the size of on-chip caches, are unknown.
