Intel has provided more details on its upcoming Xeon Phi line of processors, which will see up to 72 cores on a single processor, thanks to the Silvermont architecture. Not only that, but we can expect up to 384GB of DDR4, too.




Not only that, but the current prototype of the Xeon Phi coprocessor is capable of handling up to 32 cores, with each core capable of handling four threads for a total of 128 threads. Currently, we 8-core processors with 16 threads in total thanks to Hyper-Threading on the consumer side of the market. These new Xeon Phi processors would handle up to 36MB of shared L2 cache, and up to 16GB of the new stacked High Bandwidth Memory (HBM).




All in all, we can expect a six-channel DDR4 memory controller that can handle 2400MHz, and up to 384GB of DDR4 RAM. This is up from the quad-channel memory architecture we know and love with the X99 chipset from Intel, and the current flagship processor: the Core i7-5960X. It's interesting to note that we're seeing Intel move into HBM quickly.


The Silvermont architecture has Intel being able to promise 300% more single threaded performance over the previous generation of Xeon Phi co-processors, and up to 300% better power efficiency.
