128 bit cpus?

I read that windows 8 is due to be released 2011 or 2012 with 64 and 128 bit versions. If that is true, are there 128 bit cpus in the pipeline?
 
128bit won't be going anywhere near consumer systems anytime soon, it's all business/server orientated.

I still don't see the point. Even the current x86-64 CPUs do not access 64bits of ram, or even close to it. Windows doesn't even support above 16TB.

Quotes from Wikipedia:
"Recent AMD64 implementations now provide 256 TB (281,474,976,710,656 bytes) of physical address space (with planned expansion to 4 PB [4,503,599,627,370,496 bytes]), while current Intel 64 implementations only allow physical addressing upto of 256 TB (281,474,976,710,656 bytes) of memory."

"Current processor models implementing the AMD64 architecture can address up to 256 TB (248 or 281,474,976,710,656 bytes)[2] of virtual address space. This limit can be raised in future implementations to 16 EB"

Really? Who is going to need more than 16EB in the next 2 years? I'm not aware of a single use for anything even close to 1PB let alone more.

A 128-bit operating system? You'd need one hell of a custom build to make use of that. 18 exabytes of RAM if my calculations are correct. :p

Sounds like that is written by an AMD fanboy. They both only support 256TB of ram.

Only 256Tb... Sheesh. Is that all. Damn. I wanted twice that . . . .
 
I believe IBM or some similar company has simulated a gigantic neural network with several TB of ram. Seems doable for them to hit the 256 TB limit.
 
128 bits refers to the data width. Addressable space is obviously limited to this but that isn't the reason for going 128 bit. I'm looking forward to it, currently the only 2 ways to play with big numbers is to use awful software or pass it over to an FPGA.
 
128 bit cpus for high end business/research maybe in 5 - 10 years.

For consumers... we won't even need them for atleast 20 years from now.

I dont think this will be true. Look how far tech has advanced from 1990

16 -> 64bit

However there is still a huge number of 32 bit systems out there, so really in 20 years we might be moving to 128bit :D

Unless there is a new requirement for MASSIVE ammounts of memory or large numbers of STUPIDLY accurate numbers (if it were only a few you could emulate it anyway).

That is only the current Intel / AMD implementations, which they are raising. 64bit allows for 16EB, so much greater than any system in existance that I still can't see a use.
 
The key point of 64bit versus 128bit isn't RAM, it's the fact that the CPU can operate on 128bits of data in one cycle, rather than multiple cycles if it had to do it in 64bit chunks.

There were rumours not far back that "Windows" was coming to an end, Microsoft wants to move into cloud computing. However I can't see them rushing it forward as quickly as they would like because consumers still don't want it. Businesses won't be happy until they ram cloud computing down our throats so be assured, it will happen, just not yet.

Windows 8 is already on the horizon anyway.
 
Windows 8 has been in the "horizon" for as long as Windows 7 has been in development, the roadmaps have been around for ages.
