Following the confusion of the transistor count of AMD's Bulldozer, Llano and Trinity chips, Bright Side of News received an update from AMD that explains why the firm provided different transistor counts for these chips:
"Beginning in 2012, AMD updated its methodology for transistor counts to ensure consistency. The numbers provided for our recent Trinity launch (and all disclosures moving forward) are based on a flat device count minus de-capacitor cells. The numbers that were provided at last year’s Hot Chips conference were based on flat device + de-cap cells."
Apparently, the company had one way of calculating the number of transistors of its products such as CPUs, APUs, GPUs, chipsets and the like. With the new transistor count, AMD is no longer counting de-cap cells, but rather flat device, i.e. future FinFET transistors instead of calculating it altogether.
