Radeon RX Vega 64
The fastest current AMD graphics card is the RX Vega 64, and it comes up just short of the RTX 2070 for the same price. That’s the succinct explanation for Nvidia’s substantial jump in generational pricing on the RTX series. It’s also why Nvidia could take a chance on real-time ray tracing hardware and deep learning, because why not?
The good news is that the RX Vega 64 is still a capable card. It does well in DirectX 12 games like ForzaHorizon4, beating the RTX 2070, but that’s the exception rather than the rule, and the Vega 64 also pigs out on power. AMD nominally rates it as a 295W part, but I saw up to 100W higher power use than the 1080 Ti when playing games. That means higher fan speeds and more noise.
AMD is working on a 7nm version of Vega for datacentres, but a consumer version will depend on the performance and cost. HBM2 provides a lot of bandwidth, but it’s more expensive than GDDR5. More likely is that we’ll have to wait for the 7nm Navi in late 2019 before AMD has a GPU that can challenge Nvidia’s RTX cards.
