BeOS failed permanently when it switched from PowerPC, and dropped it for x86
Sounds an awful lot like history repeats itself.
BeOS switched to x86 because it had failed, it didn't fail because it switched to x86. The original BeBox was a PC with a PowerPC instead of an x86, there was no real advantage to them fitting a PowerPC except you had to buy their computer.
History could therefore easily repeat itself. Avoiding x86 will give you a long drawn out death, switching to x86 may or may not pay off but it will play out much quicker.
The only sane decision is between ARM or x86, which is why they own so much of the market between them. The ARM is considerably slower than x86 though, I'd prefer an Atom because it competes pretty well against the ARM but you can also go to the top end with Core I*.
Sorry, I phrased that poorly:
To read/write 64 bits of data from or to the main memory:
AMD Phenom: 33-40 cycles on average
MIPS R16000A: 11-15 cycles on average.
I apologise for the confusion.
That is pretty vague, the R16000A is 200mhz while the Phenom starts at 1.8ghz.
I'd take 40 cycles at 1.8ghz over 15 cycles at 200mhz.
The cycles increase because ram speed lags behind cpu speed, but that is what large caches are for.
If you underclock that Phenom then the average number of cycles would decrease, but it wouldn't get faster.
Your metric is irrelevant.
OlafS3,
Tekmote.NL sells some for €200-400, mostly due to import tariffs. If there was more demand I'm sure the cost would drop.
Where is the demand going to come from? How many people want such a slow computer? The netbooks have appalling battery life.
