Hey guys, I wanted to buy Ryzen 7 2700x that just came out a day ago, but for example when checking specifications on sellers website for this exact model, it shows the following:

Technology: 14 nm
Cache: 20MB

But if you go on original amd specs page, it shows 12nm and 16MB cache instead?
Am I missing something here or they lying?

Thanks!
