IBM Power5

I have been wondering around the AMD forums and came up to a dual Opteron core subject. In it was also the talk of the IBM Power5. It has 8 cores (each with Hyper Threading). It also has 144MB of Cache 3. More here.

The chip does not support Hyper Threading. It is multi threading, which is different. Hyper Threading emulates, so to speak, two processors when there is only one physical. HT allows for the execution of multiple threads, at a cost however (performance wise) Multi-threading is best done with two or more physical processors.

Just wanted to clarify that

Did you know that IBM has a 128-bit processor?

Why would someone need more than 2^64 bytes of RAM per CPU?

Big companies who like spending millions of dollars on a CPU

But it would be a total waste of money. 128-Bit should not hit until the 2030s according to the formula.

Guess it depends on what market you are aiming for. Maybe its Apple's next "big thing". Although a link or something to this would be nice.

Yes, I have heard of this before but I could never get a link.

It is true.. My next door neighbor who is a IT Director has used one before.
