Threadripper processors use the latest Zen architecture, and they can handle many cores and threads. However, this is not the only reason why the motherboards are expensive. For example, some Intel PCIe x16 slots are limited to 16x speed due to power requirements of PC, which means that multi-card configurations can’t exceed 16x speed. When it comes to Threadrippers, on the other hand, they support 40x speed capable of up to 64GB/s compared to just 16 GB/s on 16x slots. Such high speed also means larger lanes for greater bandwidth and support across the board for far more than one video card if need be.
