Globalfoundries details their 7nm Gen 1-3 process nodes

Globalfoundries has detailed their upcoming 7nm Gen 1-3 process nodes, which plans to introduce EUV technology over time and introduce yield improvements and performance refinements over time. 
For Globalfoundries 7nm will be a platform, with a roadmap that targets key improvements to the node that will increase yields, reduce prices and improve performance over time, with both second and third generation 7nm nodes using EUV technology. This means that in certain areas Extreme Ultraviolet lithography will replace Deep Ultraviolet in next-generation 7nm iterations. 
With their 1st generation 7nm process the company will achieve a 40% performance boost over 14nm FinFET, or a 60% reduction in power consumption with the same performance. 7nm also offers increased transistor density, which will make chips smaller and offer up to 50% area saving over 14nm. 
7nm will also allow manufacturers to create larger chips, with the manufacturer expecting die sizes of up to 700mm^2 to be possible. On 14nm the company can only produce chips that are up to 650mm^2 in size, which combined with 7nm's increases in transistor density will allow for the creation of much more powerful chips than before.

With second generation 7nm, Globalfoundries will add EUV technology to their 7nm platform, though this will not be a full EUV process given the current limitation of EUV manufacturing in high volumes.   

Using a more cautious approach, Globalfoundries will be using EUV technology on key aspects of their 7nm process, with a particular focus on eliminating quadruple patterning from their design wherever possible. This will improve yields for 7nm by reducing complexity and allow manufacturers to bin more chips for lower power or higher performance.

EUV technology will be added to 7nm whenever it is ready, which will likely be in 2018, which means that 1st generation 7nm products will not be designed with EUV in mind. This will mean that we won't be seeing any EUV products for a while.

With their second-generation EUV 7nm node (3rd generation 7nm), Globalfoundries plans to offer improved LER and resolution to enable higher transistor densities and offer lower power draw and increased performance. Right now performance or density gains are unknown given the experimental nature of this technology. 

3rd generation 7nm will likely include new design rules to enable the use of greater geometry scaling and higher frequencies, though this is expected to be a fairly easy process of seasoned chip designers. In this node, the majority of layers will still use DUV tech, though increased levels of EUV use are expected.  

3rd generation EUV nodes are expected around 2020, though this technology will rely on smooth development and Globalfoundries' ability to work around any issues that they come across.

When looking at the roadmap of companies like AMD, we can see that they are planning to work with 7nm in the medium-long term, supporting 7nm with Navi and Zen 2 and planning on using improved nodes line 7nm+ (likely 7nm gen 2). 

This should allow AMD to reach performance heights that are beyond what they are capable with 14nm FinFET while allowing them to decrease power draw and achieve higher levels of efficiency.

Just hope it comes out asap so AMD can get there 7nm products out quickly. They've delayed there GPUs enoughQuote

I just want to know if there's a chance that this is coming out in the first half of 2018. Because I can totally wait that long.Quote

2019 should be a good year for AMD...Quote
