Lead system architect for PlayStation 5, Mark Cerny gave a deep dive conversation into the hardware system’s architecture and how Sony designed the PS5 to benefit developers with the games they will create. This was originally planned for GDC 2020 but being that the event is canceled Sony decided to release this video today.
Cerny went in-depth on the process that led to CPU, GPU, SSD, and 3D audio. The CPU is based on AMD Zen 2 architecture, GPU is Custom RDNA 2 that has 10.28 TFLOPs, and an ultra-high-speed SSD with a 5.5 GB/s read bandwidth.
Digital Foundry made a video also detailing the specs:
The console’s official specs:
- CPU: 8x Zen 2 Cores at 3.5GHz (variable frequency)
- GPU: 10.28 TFLOPs, 36 CUs at 2.23GHz (variable frequency)
- GPU Architecture: Custom RDNA 2
- Memory/Interface: 16GB GDDR6/256-bit
- Memory Bandwidth: 448GB/s
- Internal Storage: Custom 825GB SSD
- IO Throughput: 5.5GB/s (Raw), Typical 8-9GB/s (Compressed)
- Expandable Storage: NVMe SSD Slot
- External Storage: USB HDD Support
- Optical Drive: 4K UHD Blu-ray Drive
Based on the numbers and comparing the specs of Xbox Series X, PS5 would be considered the fastest console while XSX would be considered the most powerful console. Until we get more hands-on with the consoles we will know exactly how they perform when the games come out.
