Oh look at me I have an Opteron running linux, I think I am so cool, yeah I know so much more about computers than anyone else.
Well I think not the PPC970 is a superior architecture, and here is why. PPC ISA is very clean allows for reasonable design and no MicroOPs are necessary even though some simple ones are used. SIMD processing unit can do things like FFT so much faster than the x86 offerings. Very wide architecture, 64bits, grabs 8 instructions per fetch cycle, for up to 215 instructions inflight. This means that if you have the right kind of code optimized the right way 8 operations can be completed in a single cycle, withoud SIMD it is 6 but still very impressive. Many more registers and a very advanced interconnect system between processor and other components this thing is a bandwidth beast. Once you add the advantage of IBM's production abilities such greats as SOI or even better SSOI you will see that in everyway the PPC970 is a superior design to the opteron. Now don't get me wrong the opteron is a very fast and well designed proccessor but it is clear on paper which is faster and that is the IBM chip end of story.
So here is the lesson you charlatan as much as you think you know there are people who know more my guess is you are some 15 year old kid or really immature because most people are not this crazy about platform choices. Now obvious professionals in the computer industry must follow this kind of thing because IT/IS people buy hardware and must make decisions, computer architects also look at architecture because that is their business, computer scientists are interested in systems because it allows them to develop more advanced algorithms, graphics people and also scientists/mathematicians are interested in these developments because of the sheer amounts of calculations they do. But most people do care most peoples needs are satisfied by machines much slower the truth is all the pc platforms today are so fast. These people look at relevant benchmarks only. I know I am going to buy a G5 why because for my FFT code it runs it an order of magnitude faster.
So in conclusion you really need to grow up and learn that a computer is a tool not a toy and maybe you really think your computer is nifty and like the fact that quake is super fast on your machine but the rest of us understand why we use what we use and do not make it a point to make jabs at an article just trying to show some new technology.
