Don't bother. Someone did the math some years ago and it came out to 64 MH/s or something.

you mean 64mh/s per core or for the whole processor?

64 M/Hs for the whole thing. It's just a bunch of CPU cores.

From the old thread ( https://bitcointalk.org/index.php?topic=23239.0 )

Quote
The CPU does not have any vector instructions (IIRC), so all arithmetic would have to be using standard integer instructions.  Consider also the low operating frequency (~800 MHz).  A comparable desktop CPU with no vector instructions does < 1MH/s, so this board will never exceed 64x1 MH/s.

so in two years,you think their hardware didn t evolve and got any improvment in hashing speed?

where is the moore law here?

So appyling (the Internets flawed interpretation of) Moore's law the speed is now 128 MH/s. Doesn't really help now, does it?

Ok it is double that, or quadruple that.  Doesn't really matter when there are 60GH/s ASICs being sold right.  The answer is probably correct on an order of magnitude.  A faster version isn't going to change much, it would need to be many magnitudes faster which simply isn't going to happen.

If you feel it has promise, buy one and find out.   IIRC those processors run like $1K each.  That is the raw chip so at best you are looking at a price point comparable to BFL Single SC.  You aren't going to magic 60GH/s out of 64 general purpose cores running at 800Mhz.

I just spoke with Tilera and they said it would take one thousand of their chips to compete with sha256 hashing solutions in the marketplace.  I'm looking at other manufacturers now.  If you have any advice please post here:
https://bitcointalk.org/index.php?topic=179033.0

OP please consider locking this thread as I have completed the research and re-confirmed the previous answer.  Tilera does not make a solution to the sha256 hashing problem.  April 19, 2013.
