| CUDA Core | CUDA cores are tiny calculators in a GPU that perform math operations like A × B + C. |
| GA102 Chip | The GA102 is the GPU chip used in RTX 3080, 3080 Ti, 3090, and 3090 Ti graphics cards. |
| VRAM | GDDR6X SDRAM is the video memory used in the RTX 3090 to store textures, models, and 3D data. |
| Memory Bus | The 24 GDDR6X chips in RTX 3090 communicate over a 384-bit bus transferring 1.15 TB/s. |
| PAM Signaling | Modern GPU memory uses multi-level voltage signaling (PAM-4 for GDDR6X, PAM-3 for GDDR7) to increase speed and efficiency. |
| Voltage Regulator | The VRM converts 12V from the power connector to ~1.1V for the GPU. |
| Cooling System | Heatsinks, heat pipes, and fans remove heat generated by the GPU and memory. |
