Well I am really hoping that they do a 2950X, not just the 2970X, and 2990X. It does look great though, almost as fast a 10x 3770's or 7.75x 4770K's
This so called "glue" is an engineering masterpiece, a miracle by a genius who deserves an award as big as Nobel prize...
10 times 3770s or 7.75 times 4700Ks is roughly 650W, the 2990X consumes only 250W, with a plan to decrease it significantly (say ~50%) with the 7nm process next year.
Next year, say hi to 32 cores at 130-140W, it will be game over for Intel.
