80 5D shaders and 400 ALUs of Llano), 24 TMUs and 8 ROPs. The fastest IGP ( Radeon HD 7660G) in our benchmarks uses 96 4D shaders (vs. While this may likely disappoint some readers, it's worth noting that AMD had probably laid out the groundwork for Trinity much before GCN became widely available. This would imply that the Trinity IGP has its roots to the Radeon HD 6900 "Northern Islands" desktop series instead of the more recent 28nm GCN architecture. Now, AMD has taken the liberty to install the VLIW4 structure into the Trinity GPU. Previous GPUs as found in Llano cores use VLIW5 units that were introduced during the Radeon HD 5000 "Evergreen" series. The graphics core utilizes a new architecture that primarily affects the structuring of shader ALUs. ![]() To catch up to Intel and its HD 4000 graphics, AMD has made significant changes and has improved the DirectX 11-ready Trinity IGP. The top Llano models make use of the Radeon HD 6620G which, even after nearly a year after its release, can still compete with the best IGPs.
