Trinity's graphics is an improvement over Llano's but it still employs the VLIW4 architecture of the Radeon 6000 series instead of the more modern Graphics Core Next on recent Southern Islands GPUs (UVD engine on the Radeon 7000 was backported though).
Double Precision is capped at 1/16 SP.
Heterogeneous System Architecture is a developer initiative by AMD to seemlessly utilize CPU and GPU (hence APU) to accelerate applications with scalar processing on CPU and parallel processing on the GPU (as a co-processor).
