AMD: “No Chiplet APU Variant on Matisse, CPU TDP Differ identical as Ryzen-2000” – AnandTech

Indubitably one of many mountainous questions popping out of AMD’s CES announcements was if its new CPU plan, codenamed Matisse and which enables two chiplets and an IO die on a single kit, would enhance a form of chiplets being graphics basically based totally in characterize to produce an APU. In our discussions with AMD, we purchased affirmation that this would possibly now not be the case.

The new Matisse plan is the platform for AMD’s subsequent generation of desktop processors. The layout shown at CES this year represented the plan as having a single IO die, about 122.6 mm2 and constructed on GlobalFoundries 14nm, paired with a chiplet die, about eighty.eight mm2, containing eight cores and constructed on TSMC’s 7nm. There would possibly be obviously space on that kit for one other CPU chiplet, and there has constantly been questions if the chiplet plan is amenable to the use of a graphics.

AMD stated that, at this time, there can be no version of the most contemporary Matisse chiplet layout the effect a form of chiplets can be graphics. We had been told that there can be Zen 2 processors with integrated graphics, presumably popping out powerful later after the desktop processors, but constructed in a thoroughly different plan. Within the extinguish APUs are both cell first besides diminish cost substances (in most cases), so thoroughly different plan choices will resolve on to be made in characterize to make stronger that market.

This does now not rule out a future processor the use of chiplet graphics, here is actual for Matisse.

Our contacts at AMD additionally discussed the TDP differ of the upcoming differ of Matisse processors. Given AMD’s definition of TDP, referring to to the cooling efficiency required of the CPU cooler, the differ of TDPs for Matisse can be the identical as most contemporary Ryzen 2000-sequence processors. This contrivance we would also explore ‘E’ variants as puny as 35W TDP, the total manner up to the head ‘X’ processors at 105W, a lot just like the most contemporary Ryzen 7 2700X. We had been told that the corporate expects the processors will match inside of that differ. This must always be expected on some level, given the backwards compatibility with most contemporary AM4 motherboards in the marketplace with a BIOS change.
