Lol, people on the internet. Your original comment wasn't about volta in the enterprise, it was about consumer volta. Your just grasping at straws /gg
"Nvidia on the other hand can push Volta as a single die solution, and THEN still double its potential through the MCM-solutions they have planned."
Lol, you really have no understanding of this do you? Why in the world would Nvidia continue to make pricey large dies if they could make multiple smaller and cheaper ones? The answer: they can't. AMD is the only CPU manufacturer on the market right now that managed to stitch together multiple higher performance CPUs, something not even Intel can do yet with an R&D budget bigger than the value of the entirety of AMD. Nvidia has even less experience with interconnects then either AMD or Intel and you just suddenly expect them to be able to have the same groundbreaking achievement as AMD did? You are delusional. Nvidia doesn't even have an MCM on their roadmap so your looking at volta and then the next architecture AT LEAST still being single.
This is about as far as Nvidia has gotten

of which, Intel has had MCM processors in the past that ultimately failed due to latency between dies. Notice the article's publication date, after Ryzen's launch. This means that Nvidia didn't think MCMs were feasible until after Ryzen. This also means they have zero progress into actually implementing this into their GPUs for real. Ryzen comes out and all of a sudden Nvidia starts talking up MCMs like they are the future. I remember the same thing happening when the original iphone came out and it took others YEARS to catch up.
"Surely you realize that Vega is ALSO still trailing a full GPU tier behind in terms of gaming performance, right? It's more than 30% behind, so in fact it is last year's high performance
of the mid tier SKU."
I don't even know what card you are talking about. WIthout even referencing the card or sources you are just talking out of your ass. Vega 56 = 1070 and Vega 64 = 1080. Their performance are on par with each other. I know you can be talking about the 1080 Ti, because it isn't a year old nor is it mid tier. All of this doesn't change the fact that these cards are still the best Nvidia's got right now. If you didn't realize, your own logic can easily be used against you. For example, The R9 390 was the same price as the GTX 970 and yet the 390's GPU was over 2 years old and still had double the RAM.
