Whether you state thousand million or billion its same arabic numeral, 1,000,000,000. 
Here upcoming cpu will have just about same number of tranies as dual processor TOP end does today, yet it all has migrated to one cpu die.

2 die or one die, its question of speed. Skulltrail is 4 ghz/sec with near 2 billion total, while condensate will be 2 billion on one die, yet only 2 ghz/sec. so again get dem pencils out & GO FIGURE.

The fact that they are all on the same die is impressive (unlike the RAM comment). Well only if the yield doesn't suck

Memory chips have packed in over 2 bilion transistors for some time. Each memory chip of a 2GB 8 chip module has over 2 billion transistors
