If you are designing a switch, router or other network box and SDN and/or NFV are focus areas for you, I'd like to hear what you most want in 2015 silicon.

Very impressive SoC devices from both companies...any idea about chip pricing?

Similar PowerPC parts have been priced at 120-240 USD in 1K. The 6 core 4016 is USD420 or so on their web site. 

But these parts are more hobbled. I do not see DPAA or SRIO for multi-chip connectivity.

So USD 120-160 is an Ok price. Ideally should be sub USD 100. I reckon USD 80 is a good price.

thank you @GSMD...I was hoping for <100 USD to jump start SDN hardware

Take a look at their PowerPC parts, the 2041 (older 45 nm part) which is being replaced by the 2080 should be sub USD 1000. I frankly prefer the PowerPC core to the ARM cores.

 

Of course i prefer my own Shakti (Risc-V) cores to anything else but I guess i am biased being the core's architect !

For our own platform, we have used the T4240 (all of 24 cores !). Expect our SDN proto to come up in a couple of weeks.

@GSMD: Observers say comms OEMs are consolidating on ARM and x86, largely for their large ecosystems. Why do you buck the trend?

1. I am bucking the trend ! If you look at it, Microchip just licensed MIPS a few years ago when they could have licemsed ARM. Cores are really immaterial, it is the AXI eco-system that matters.

2. In the case of Freescale, they havd chosen to play both cores, PPC for higher end and ARM for lowe end. Thsi will remain so at least for the next 5 years. The T4240 is just getting design production wins (started shipping just a month ago in production). Their encryption product, the C29x is also PPC. No way in the higher end networking world and the telecom world, parts that got designed in in 2014 will be swapped out that easily.

3. The ARM64 cores are simply not mature enough for  for high end virtualization and other such features. The e6500 core is pretty well tuned for networking apps (shallow pipelines for starters). The A57 is one size fits all. You cannot seriously tell me the A57 core can take on the e6500 PPC core in networking  and the IBM Power8 in servers !  If you believe that I got a  bridge in Chennai I want to sell you ! Not as impressive as the Brookly bridge perhaps ...

Bottom line for commodity products there is a universal move towards ARM for SW reasons but at mid to higher perf levels, that trend is not that clear. Broadcom is on MIPS , FS is on PPC, Cavium is on MIPS,  EZchip is custom and only Netronome is partially on ARM. Intel does not count yet. Also notice none of them have an AXI framework.  Dumping a core is easy, dumping your NoC and I/O subs-sysyems is a whole different ballgame. In that case, just switching to an ARM core does not buy you much. Would love to look at Freescale's source code for the processor.

Does not seem like a trend to me.

And repeat after me a 100 times -  "I shall stop listening to analysts and start listening to engineers who actually design these systems"
