Architectural Differences

  1. Lithography: The RTX 4080 and the rest of the 40 series of graphics cards utilize cutting-edge 5nm manufacturing nodes, whereas the RTX 3090 Ti uses an older 8nm process.
  2. Clock Speeds: The RTX 4080 clocks anywhere from 2205MHz at the base with a boost of up to 2505MHz, whereas the RTX 3090 Ti can clock from 1560MHz to 1860MHz.
  3. VRAM: The RTX 4080 comes with a sizeable VRAM buffer of 16GB, whereas the RTX 3090 Ti comes with the highest VRAM amount possible on a consumer gaming GPU; 24.
  4. TDP: The RTX 4080 is rated to reach a TDP of 320 watts, which is significantly lower than the RTX 3090 Ti’s 450-watt TDP.
  5. Bus Width: The RTX 4080 has a pretty sizeable 256-bit, whereas the RTX 3090 Ti takes this up to a 384-bit bus, allowing for more bandwidth between the GPU and the VRAM.
