At least one of AMD's partners is planning to skip making a custom Radeon RX Vega 64 graphics cards, and another one is on the fence, according to TomsHardware. The supposed issue for both companies is the amount of variance in the quality of Vega GPUs.

It is generally assumed that whenever AMD or Nvidia release a new graphics card, third-party partners will follow suit with specialized models that feature factory overclocks and custom cooling solutions. And that is typically the case, save for the oddball SKU that is reserved for bulk OEM system builders.
