What is Pentax K20D Processor speed ??

Hi there..
Need Help..
Anyone can let me know what is Pentax K20D Processor speed ??
I read through the reviews from the net.. did not find/mention on the processor speed and another question is K20D is 12 bits or 14 bits camera? Help explanation, I was questioned by someone... and I don't know how to find the answer..

Thanks..

RAW files are 12-bit per channel based on 14-bit A/D.
That's all I know.

Why would one care about the clock speed? From what I read faster clocks produce more noise in general. Too slow a clock speed and the camera doesn't work just kidding.
I'll try to find out.
for now I'll guess 100MHz.......

But is it a RISC or CISC processor?

Custom ASIC. Probably relatively low clock speed but very parallelized and function-optimized. No way it can be directly compared to any general purpose CPU.

Disclaimer: It probably has a general purpose core for basic functions, but the real "grunt work" will be done by custom circuitry in the ASIC (in the case of Pentax, the PRIME chip.)

OK according to best guess estimates we have 3 choices 50,60 or 100MHz depending on CPU vendor..
I'm now leaning to the 50MHz Fujutsu, since I believe they used them in the past and the PRIME engine is believed to be a custom Fujutsu device (w a FSB speed to match the RAM). Probably more economic to stick w/ 1 vendor.
Anyone want to take one apart?
All speculation of course...
