The Trinity GPU

Trinity the GPU

Though we always felt that that on the processor side AMD might have forfeited a little bit too much, they compensate with a very powerful graphics engine harbored inside that CPU. Let's realize one thing here, integrated GPUs (whether that is in the chipset or CPU) have always have been bad in terms of performance. Now we are not claiming that integrated solutions (especially in a CPU) will ever reach the level of a dedicated graphics card, but we do have to acknowledge that what AMD placed into Trinity is just downright impressive.


We already spilled the beans a little but for the GPU part of the APU things have changed massively. Trinity has a Radeon GPU with 384 shader cores. The distinct difference is that Llano had an architecture based on the Radeon 5000, Trinity makes use of Radeon 6000 architecture which you all know under the northern islands codenames. Also a new model video-encoder has been integrated, based on the latest Radeon 7000 series. AMD calls the GPU embedded into the A10 5800K the HD 7660D and it runs at 800 MHz. Per chip series (A10 / A8 / A6) the GPU configuration will be a little different

So not all Trinity APUs will have 384 cores. Depending on the SKU these will differ:

  • Trinity A4 has 128 cores dubbed Radeon HD 7480D
  • Trinity A6 has 192 cores dubbed Radeon HD 7540D
  • Trinity A8 has 256 cores dubbed Radeon HD 7560D
  • Trinity A10 has 384 cores dubbed Radeon HD 7660D 

So less shader cores but more performance, how is that possible you might wonder ? Well AMD made the transition towards radeon 6000 architecure, and that's better known as the VLI4 architecture. Per core that means more efficiency, but also tesselation performance will have gone up a notch or two.

That 7xxxD GPUS makes the IGP a fully functional DirectX 11 GPU in the Trinity die. To complement the multi-media experience, the UVD engine is harbored in Trinity  as well, it is actually UVD3, the latest revision used on the Radeon 6000/7000 series and that means serious support for Full HD content playback with even 3D Blu-Ray capability. Quite important to know is that the new UVD engine also has a H.264 video encoder that you may compare with Intels Quick Sync.


The IGP will provide support for two monitors and all common connectors are supported including HDMI, DVI, DisplayPort and DSUB (VGA). Oh and being a Radeon 6000/7000 based IGP, yes may even drive up-to four monitors thanks to Eyefinity.
