  "The catch for AMD is that what they need to price RX Vega at to be competitive and what it should be able to do are at odds with each other. The Vega 10 is a large, power-hungry GPU. Much larger and much more power hungry than NVIDIA’s competing GP102 GPU. And while this isn’t an immediate consumer concern – we pay what the market will bear, not what it costs AMD to make a chip with a nice gross margin on the side – from a technology and architectural perspective it indicates that AMD has moved farther away from NVIDIA in the last couple of years. Whereas the Radeon R9 Fury X was almost a win that AMD didn’t get, the RX Vega 64 doesn’t appear to be fighting in the weight class it was even designed for. Instead the power efficiency gap between AMD and NVIDIA has grown since 2015, and apparently by quite a bit.

  In the meantime, from an architectural perspective there’s a lot I like about Vega. I’m interested in seeing where fast FP16 performance goes in the gaming market, and the primitive shader looks like it could really upend how geometry is processed at the GPU level given sufficient developer buy-in. Meanwhile the high-bandwidth cache controller concept is a very forward looking one, and one that in time may prove a major evolutionary step for stand-alone GPUs. However I can’t help but wish that these advancements came with a more competitive video card stack. As great as Vega is architecturally, it’s clear that performance and power consumption aren’t where they need to be for AMD to take on a surging NVIDIA."

  Szerintem elég jól összefoglalták a jelenlegi helyzetet.
