I'm totally intrigued by the Vega 64 single precision tflops. I checked pricing and it looks like you can get a Vega 64 for around $520 Gigabyte AMD Radeon RX VEGA 64 | eBay but the Vega 56 is around $450 MSI AMD Radeon RX VEGA 56 Reference | eBay Why would you get a Vega 56 if the 64 is only $70 more? 20% more performance per slot for $70? What am I missing here? Are these like the same for crypto? If I'm making an AI or crypto rig then 20% more per GPU is easily worth $70 since that's one less GPU per 5.
