AMD is actually using three chipsets for Trinity: The A55, A75 and A85X. The A55 and A75 are carried over from Llano, and AMD developed the A85X chipset for this round with Trinity. As we see, AMD gives a good/better/best strategy with all three chipsets. Today, we will use the ECS A85F2-A Motherboard for testing.
Let’s compare the A75 and A85X chipset:
Looking at the block diagram, we see only one change. The A85x still uses the Hudson controller hub and we see eight serial ATA ports over six with the A75 chipset and reconfigured GPU lanes. The socket does change from 905 pins to 904 and the change in socket is confusing. We do not engineer processors but only review them, and needless to say, we feel the socket change might hurt. The upgrade path for Llano users would have been a better move in our opinion; however, the socket change may play into future releases, and it might have been necessary. Also, We have to admit that we have been spoiled by the never ending socket AM3+.
Here is the A85X chipset:
Let’s take look at the product features and specification on the ECS A85F2-A.
