Clearly it's anti-competitive because it's restricting the ability for AMD to market its products for their intended purpose which is a speech issue.
The thing is we know nothing more and whom are in this program. If its Evga, who cares, they are exclusive anyways. Just have to see what happens with Asus, MSI, Gigabyte right? Who else uses different IHV's for graphics products and have the same lines for their gaming products?
Just to keep this on point
NVIDIA will tell you that it is 100% up to its partner company to be part of GPP, and from the documents I have read, if it chooses not to be part of GPP, it will lose the benefits of GPP which include: high-effort engineering engagements -- early tech engagement -- launch partner status -- game bundling -- sales rebate programs -- social media and PR support -- marketing reports -- Marketing Development Funds (MDF). MDF is likely the standout in that list of lost benefits if the company is not a GPP partner.
This is the part that doesn't make it anti competitive. Because all these benefits are opt in benefits right now anyways
Right now rebates are done a per AIB basis, same with bundles that is nV based solely. AIB's can do their own bundles if they want to. Social media and PR, hey nV has no obligation to help others with their company.
