Just a couple of hours before I have received the metal case I have also received a highly classified communication in which the parameters for the new weapon were disclosed. The name was AMD Radeon R9 295X2 and besides using a single PCB and a different cooling solution, the specs detailed in the technical paper seemed very familiar. After all, on the same PCB I could now find two cores which I knew very well from AMD R9 290X. And even if the new weapon was called Vesuvius instead of Hawaii, the specs were the same, except for the clocks.

And even the clocks weren’t that different. The memory was running at the same speed, while the cores on AMD Radeon R9 295X2 were running at 1018MHz (compared to 1000MHz on AMD R9 290X). I know, only a 2% speed bump, but we have to take into consideration that we now have 2 cores on the same PCB, so that was not an easy task. Under this circumstances, the 500W declared TDP was coming as no surprise, especially when we were talking about a weapon with 12,4 billion transistors.

      A little typo in the second pharagraph: “The timing was to precise to be just a coincidence…”. The correct form of the first “to” is “too”, not “to”.

      Also you wrote “before” as “be fore” on the third page.
