The PlayStation 5 is powered by a custom system on a chip (SoC) designed in tandem by AMD and Sony, integrating a custom 7 nm AMD Zen 2 CPU with eight cores running at a variable frequency capped at 3.5 GHz. The integrated GPU is also a custom unit based on AMD's RDNA 2 graphics architecture. The GPU has 36 compute units running at a variable frequency capped at 2.23 GHz, making it capable of a peak theoretical performance of 10.3 teraFLOPS. The GPU supports hardware-accelerated real-time ray tracing, a rendering technique that allows for realistic lighting and reflections. The console has 16 GB of GDDR6 SDRAM with a peak bandwidth of 448 GB/s, and integrates Bluetooth 5.1, and 802.11ax (Wi-Fi 6). Both the CPU and GPU are monitored by a special boost system incorporating AMD's SmartShift technology that adjusts the frequency of these units based on the current activities
