Modern Consoles Use 64-bit Architecture—But That's Not the Whole Story

All current consoles (PS5, Xbox Series X/S, Switch) use 64-bit CPU architectures. But "bits" alone don't define performance.

What "64-bit" Means Here:

• CPU registers, address bus, and instruction pointers are 64 bits wide.
• Allows addressing >4 GB RAM (critical—PS5/XSX have 16 GB; Switch has 4 GB).
• Same as modern PCs (x86-64 / ARM64).

What Actually Determines Power:

Bottom Line: 64-bit is the baseline. Real-world performance comes from CPU/GPU microarchitecture, clock speeds, memory bandwidth, and storage speed—not the bit width.
