Zen 2 is a significant departure from the physical design paradigm of AMD's previous Zen architectures, Zen and Zen+. Zen 2 moves to a multi-chip module design where the I/O components of the CPU are laid out on its own die which is separate from the dies containing processor cores, which are also called chiplets in this context. This separation has benefits in scalability and manufacturability. As physical interfaces don't scale very well with shrinks in process technology, their separation into a different die allows these components to be manufactured using a larger, more mature process node than the CPU dies. The CPU dies (referred to by AMD as core complex dies or CCDs), now more compact due to the move of I/O components onto another die, can be manufactured using a smaller process with fewer manufacturing defects than a larger die would exhibit (since the chances of a die having a defect increases with device (die) size) while also allowing for more dies per wafer. In addition, the central I/O die can service multiple chiplets, making it easier to construct processors with a large number of cores.
With Zen 2, each CPU chiplet houses 8 CPU cores, arranged in 2 core complexes (CCXs), each of 4 CPU cores. These chiplets are manufactured using TSMC's 7 nanometer MOSFET node and are about 74 to 80 mm2 in size. The chiplet has about 3.8 billion transistors, while the 12 nm I/O die (IOD) is ~125 mm2 and has 2.09 billion transistors. The amount of L3 cache has been doubled to 32 MB, with each CCX in the chiplet now having access to 16 MB of L3 compared to the 8 MB of Zen and Zen+. AVX2 performance is greatly improved by an increase in execution unit width from 128-bit to 256-bit. There are multiple variants of the I/O die: one manufactured on GlobalFoundries 14 nanometer process, and another manufactured using the same company's 12 nanometer process. The 14 nanometer dies have more features and are used for the EPYC Rome processors, whereas the 12 nm versions are used for consumer processors. Both processes have similar feature sizes, so their transistor density is also similar.
AMD's Zen 2 architecture can deliver higher performance at a lower power consumption than Intel's Cascade Lake architecture, with an example being the AMD Ryzen Threadripper 3970X running with a TDP of 140 W in ECO mode delivering higher performance than the Intel Core i9-10980XE running with a TDP of 165 W.
On 26 May 2019, AMD announced six Zen 2-based desktop Ryzen processors (codenamed "Matisse"). These included 6-core and 8-core variants in the Ryzen 5 and Ryzen 7 product lines, as well as a new Ryzen 9 line that includes the company's first 12-core and 16-core mainstream desktop processors.
The AMD 4700S and 4800S desktop processors are part of a "desktop kit" that comes bundled with a motherboard and GDDR6 RAM. The CPU is soldered, and provides 4 PCIe 2.0 lanes. These are reportedly cut-down variants of the APUs found on the PlayStation 5 and Xbox Series X and S repurposed from defective chip stock.
Initially only provided to OEM; later, AMD released retail Zen 2 desktop APUs in April 2022.
Common features of Ryzen 4000 desktop APUs:
In 2022, AMD announced the Mendocino ultra-mobile APUs.
