Thunder X2 CPU - mildly interesting
http://www.cavium.com/ThunderX2_ARM_Processors.html
I am surprised by the bit "up to 54 cores with up to 3.0 GHz" I presume that the faster speed will come with lesser core count, say 16. Intel's Xeon Phi only does about 1.2 GHz on 60 cores. |

No TDP ?

No TDP ? It's not out until 2017. Many things can happen to it, before it is delivered. http://semiaccurate.com/2016/05/30/n...s-thunder-tx2/ Thermal info is jealously guarded, as you don't want to scare Intel into action. And besides, the thermal details will vary with what interfaces are wired up on the circuit board. It has a lot of I/O. You can safely say it is "less than 300W", because that is the highest power I've heard of to date, for a single IC (BitCoin miner chip). The BitCoin miner would be a "nice" design, as it doesn't need a lot of I/O, and the compute units heat uniformly from one side of the chip to the other. Never any "hot spots". So we can say, the new ARM chip won't be able to touch that one. It'll require a lower TDP than that. The highest CPU TDP might be the AMD 9590 at 225W (a purposeful stock overclock). So they should be able to do that well. But they will have a lot of I/O - if soldered down, the chip will need a serious underfill solution (like a GPU uses). If socketed, the socket will need to be an engineering marvel, due to the I/O count. Six channels of memory, does not a small chip make. Paul |
