I don't understand, what is the REAL TDP of G-cards ?
That's because of the use of HBM rather than traditional DDR-styled memory in GDDR5X. The GDDR5X is fast enough and has a plenty large memory bus and you'd probably never notice a difference between the HBM and GDDR5X.
that memory bus difference :O
