128bit processors?

[Fearless Leader]

how long before we see 128bit processors. and acording to wiki 128 is the limit... i think...

In theory a 128-bit address range would be it, no further increase in memory addressing size would occur (at least not for computers located on this planet). The entire universe is esitimated to contain about 2^300 particles[1], and the earth contains about 2^166. To fill a 128-bit memory (or filesystem) would require more energy than boiling the oceans[2].

anybody care to translate this and explain it?

The article's saying that 128-bit memory addresses would be more than sufficient to point to unique addresses for more information than you'd ever need.

Basically, the more bits, the more unique spots to store something, just like more digits in a phone number means more possible unique phone numbers.

However, it doesn't mean 128-bit processors are the end of the road - processor bit depth is, in essence, a measure of how "wide the road is" for instructions and data to travel, and, for some applications, wider is better. However, a 1024-bit processor, should one be developed, needn't use 1024-bit memory addressing.

ohh thnks, and does anyone know why it would take so much energy to fill the memory? is it cuase their is just soo many particles it consumes an unfeasable amount of energy?i think i just answered my own question...

Well, if 18 Exa-bytes is still too little then try 128 bit computers with:- 340,000,000,000,000,000,000,000,000,000,000,000,000 U V W X Y Z E P T G M K 340 Uda-bytes RAM memory or 170 Zetta-Googles. It´s still not that much. A person has about 7 Xona-atoms. so we can only fit in about 50 billion people to RAM. Going up to 256 bits and RAM of 100 Tebilubibytes (10^77). There are this order of atoms in the universe so a 256 bit computer could just fit that in. Errr.... wait a minute, there wouldn't be enough atoms to build the RAM.

interesting tid bit of an argument as to why 256 bit memory would be impossible.
