The GPU core clock speed, measured in MHz or GHz, indicates how fast the GPU can process data. A higher clock speed generally translates to better performance. However, clock speed is not the only factor that determines performance, as other factors such as the GPU architecture and memory bandwidth also play a significant role.
Memory Size and Type (VRAM)
Video memory (VRAM) is dedicated memory used by the graphics card to store textures, frame buffers, and other graphical data. The amount of VRAM can significantly impact performance, especially when running games or applications with high-resolution textures or complex 3D models. The memory type also matters; GDDR6 is generally faster than GDDR5. A larger and faster VRAM capacity allows the GPU to handle more complex scenes and larger textures without experiencing slowdowns.
Thermal Design Power (TDP)
Thermal Design Power (TDP) is the maximum amount of heat the graphics card is designed to dissipate. A higher TDP generally indicates a more powerful graphics card, but it also means that the laptop will generate more heat and may require a more robust cooling system. The TDP can significantly affect the sustained performance of the graphics card, as a card with a lower TDP may be throttled (have its clock speed reduced) to prevent overheating.
External Graphics Cards (eGPUs)
While most laptops come with either integrated or dedicated graphics, there’s another option: external graphics cards (eGPUs). An eGPU is a standalone graphics card housed in an external enclosure that connects to a laptop via Thunderbolt 3 or Thunderbolt 4.
