Title: Possible mining hardware based on RISC Post by: navimarin on June 27, 2011, 03:31:51 PM I have been following all kinds of hardware threads on this board for a while now.
All FPGA/ASIC threads where very interesting. I learned that cost per kW/h differs from 0.04$ to 0.25€ per users I have seen so far. As I am more on the upper end of that scale, power efficient solutions are most welcome. I would like to know what you think about this processor http://tilera.com/products/processors/TILE64 (http://tilera.com/products/processors/TILE64) or ready as card http://tilera.com/products/platforms/TILEncore_cards (http://tilera.com/products/platforms/TILEncore_cards) It is said to consume about 20W. I fear that, as no price tags are provided and the I/O ports seem to target premium application scenarios, it will be priced too high. Still, is anybody familiar with this specifice processor or give a performance comparison? It seems there are no dev boards available (at least not publicly). At motherboard with a few of these cards would be fun, since they are programmable with standard C++.

"Combining multiple C-programmable processor tiles with the iMesh multicore technology enables the TILE64 processor to achieve the performance of a fixed function ASIC or FPGA in a powerful software-programmable solution."
I thought I read that it is based on RISC but can't find a reference at the moment. Title: Re: Possible mining hardware based on RISC Post by: lame.duck on July 05, 2011, 12:41:45 PM you could ask the for an evalution version of theiy development software, and look how many instructions are needed for a single Hash and divide the Clock rate ... and compare the number with ATI-GPU. As there are only few instructions that are run in a loop, there are no separate cores with dedicated different instruction streams needed.
I would say, nice toy for a speed loving geek (yes there are serious applications for sure), but not the optimal solution for bitcoin mining. Title: Re: Possible mining hardware based on RISC Post by: navimarin on July 05, 2011, 01:27:34 PM A geeky toy for sure. I already tried to obtain a dev board. Unfortunately they do not respond at all...

Unfortunately they do not respond at all... I'd really like to see a hash benchmark on the tilera, since they claim to be on the verge of a 1000 core chip they have 32; 64 and 100 core chips as is now Title: Re: Possible mining hardware based on RISC Post by: Silverpike on August 03, 2011, 07:11:06 AM I've already looked into this. The speed estimates are very low for this device.
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. I also should mention that Tilera is in bankruptcy, because GPU computing destroyed their business (for obvious reasons). No person in their right mind would pay $500 for 64 MH. Title: Re: Possible mining hardware based on RISC Post by: navimarin on August 04, 2011, 10:17:47 PM I got a reply from Tilera. They got hosted starting at 30k $. They offered to lower it to 13k As introductery. I think this Thing is more about I/O since they have 2x 10 gbps Ports and so on. 1024 cores Gould have been interesting though.
