Sony PlayStation 5 leads with superior 4K performance from its custom AMD Zen 2 CPU and RDNA 2 GPU plus ultra-high-speed SSD (per grounded facts). Steam Deck OLED counters with a 7.4-inch HDR OLED 90Hz display, Wi-Fi 6E, Bluetooth 5.3, and 16GB LPDDR5X RAM in a portable package. The PS5 is the stronger pick for home console gaming while the Deck excels when mobility is required.
