The PlayStation 5 uses AMD's Zen 2 with 8 cores running at a variable frequency capped at 3. 5 GHz. The GPU is a customized system-on-a-chip (SOC) based on AMD's RDNA 2, featuring 36 compute units running at a variable frequency, capped at 2. 23 GHz, and capable of 10. 28 TFLOPS. Both the CPU and GPU are monitored by a special boost system incorporating AMD's SmartShift technology that adjusts the frequency of these systems based on the current activities of both chips, to target ideal constant power drawn and a model SOC performance. For example, if the CPU is running at lower activity, the boost system may reduce its frequency and increase the frequency of the GPU to allow that GPU to run at higher performance without otherwise affecting power use or cooling. Because of this, Cerny said that direct comparison based on compute units or FLOPS to other hardware systems may not be accurate. The GPU includes support for hardware acceleration of ray-tracing rendering, enabling real-time ray-traced graphics. The hardware includes a new audio technology called Tempest Engine based on the AMD GPU technology, which allows not only for hundreds of sound sources within a game to be accounted for in producing audio output compared to 50 for the PlayStation 4, but also how that audio is presented based on the end user's device and preferences. The unit will include 16 GB of GDDR6 SDRAM with a bandwidth of 448 GB/s.
