If you are looking for the best graphics performance possible, it is very likely that your PC DIY rig features a 2-way, 3 –way or even 4-way SLI or Crossfire configuration. Did you know that X99 PCIe design offered a total of 320Gb/s bandwidth for your multi graphics card configuration? GIGABYTE X99 motherboards feature a unique PCI Express design that utilizes 100% of all 40 lanes from the CPU when in a 4-Way or 3-Way graphics configuration. Standard designs limit all 4 main PCIe lanes to x8(64Gb/s) bandwidth, but thanks to the onboard external clock generator combined with the direct connection of one of the x16 lanes to the CPU (switchless design), GIGABYTE X99 motherboards can unlock the full bandwidth available and provide the best graphics bandwidth possible to the user.
Here is an introduction video of the PCIe design available on GIGABYTE X99 series motherboards.
