AMD: “No Chiplet APU Variant on Matisse, CPU TDP Vary similar as Ryzen-2000”

One of many massive questions in AMD's CES bulletins was whether or not the brand new CPU design code-named Matisse, which permits for 2 chiplets and an IO dice in a single bundle, would assist a kind of graphics based mostly chiplets an APU. In our discussions with AMD, we obtained affirmation that this is not going to be the case.

Matisse's new design is the platform for the subsequent technology of desktop processors from AMD. The format proven at CES this yr represented the design as a single IO chip of roughly 122.6mm2, constructed on GlobalFoundries 14nm paired with a chiplet chip of roughly 80.8mm2, the eight cores comprises and is predicated on 7Mm of TSMC. There’s clearly room for one more CPU chiplet on this bundle, and it has all the time been requested if the chiplet design is appropriate for utilizing a graphic.

AMD said that there is not going to be a model of Matisse's present chiplet format at the moment, with considered one of these chips being graphics. We have been instructed that there can be Zen-2 processors with built-in graphics, which can most likely seem a lot later after the desktop processors, however can be integrated into a unique design. Finally, APUs are each cell first and cheap components (normally), so totally different design selections should be made to assist this market.

This doesn’t exclude a future processor with chiplet graphics, this solely applies to Matisse.

Our contacts at AMD additionally mentioned the TDP vary of rising Matisse processors. Given the definition of TDP from AMD, which refers back to the cooling efficiency of the CPU cooler, the TDP vary for Matisse is similar as for the present processors of the Ryzen 2000 sequence. Because of this we are able to see "E" variants all the way down to 35W TDP, as much as 105W "X" processors much like the present Ryzen 7 2700X. We have been instructed that the corporate expects that processors will match on this space. This is because of backward compatibility with present AM4 motherboards in the marketplace with a BIOS replace at a sure degree.
