PlayStation 5 custom SoC high-definition: RDNA 2 architecture GPU is in the middle of the chip
Some time ago, the famous infrared photographer Fritzchens Fritz brought high-resolution photos of AMD Ryzen 5 5600G, showing its internal structure, allowing people to have a deeper understanding of this APU. Recently, he shared a new subject: the SoC of the PlayStation 5 game console.
The PlayStation 5 game console uses AMD’s custom SoC, code-named Oberon. It has eight Zen 2 architecture CPUs with a frequency of 3.5 GHz (variable frequency), and RDNA 2 architecture GPUs with a frequency of 2.23 GHz (variable frequency).
L3 cache is 12MB, floating-point computing performance reaches 10.28 TFLOPS, supports 4K@120Hz and 8K video output, and is manufactured using TSMC’s 7nm process.
Through the photos, you can see how AMD arranges billions of transistors. The GPU of the RDNA 2 architecture is located in the middle of the chip and is divided into multiple CUs. Next to it is the Zen 2 architecture core, and then there is the part responsible for I/O, which looks very organized. You can clearly see AMD’s Infinity Fabric, which connects the entire chip and the L2 cache. There is also a GDDR6X memory controller at the edge, and a PHY (physical layer) interface, which is responsible for data entering and leaving the SoC. Fritzchens Fritz has taken a lot of photos. If you are interested, you can check it out on his Flickr.
Some people might think that AMD had introduced a 4700S processor kit before, and it was confirmed after verification that it was using a custom SoC for the PlayStation 5 game console. The South Bridge chip is AMD A77E FCH, with 16GB of GDDR6 memory. Unlike the PlayStation 5 console, these kits have the graphics unit disabled
