AMD ARM vs. Intel Atom

AMD gave few details on Hierfalcon. On the face of it, it's hard to see how it will differentiate itself over the Intel Rangley chip shipping today, a 2-8 core 64-bit Atom with cryto and other accelerators for comms systems--let alone what I woulod expect to see in this timeframe from TI, Freescale and others.

In short, I've yet top be convinced ARM is any kind of savior for AMD.

That was a nice architecture.

@rick, I am curious to find out what sort of market share AMD currently has on the communications and storage systems market. Any idea?

Not sure how AMD will differentiate with other ARM providers. Rick, you did not mention X-Gene from Applied. It seems they have similar features in term of core count and interfaces and have silicon today.

 

There are also the existing PPC and MIPS players in this crowded market, do you think ARM or x86 will gain market share there?

@Junko: AMD has very small share of the comms market. Intel claimed it has a 10% share. Most of it has been PowerPC, some MIPS and some proprietary. But both x86 and ARM are on the rise here.

@Tarra: TI, LSI and Freescale are moving their comms SoCs from PowerPC to ARM cores. (Power is on the outs in embedded now.)

X86 has been gaining strength in comms for some time in the control plane. Now Intel is npushing to get int the dataplane with hw accelerators and software kits.

@Rick, thanks. So, then, the question is how ARM would be helpful for AMD to cultivate the comms market -- which is new to AMD. That's an interesting challenge to say the least.

If there is anyone out there who can help me understand this, please chime in.

@Junko: The problem for AMD is it becomes the fourth or fifth ARM comms SoC vendor--if not even further behind.

Intel just launched Rangely, an 8-core 22nm SoC with hw accelerators for comms, so there to it is running a distant second.

But I agree: it would be great to hear from some ARM comms SoC vendors and users. What do you think about this latest player and what little we know about Hierofalcon, it's first gambit?

Actually till now most of the ARM comms players have been smaller fry. bigger player can grab market share through non technical advantages like easy of availability, larger user community, lower MOQ, no NDA requirement. Try getting datasheets for comm processors from Cavium or Broadcom as a small oem ! I often ended up with Freescale even though there were better parts around simply because You could whip out a credit card and order dev kits or samples. On a tech note, not sure what AMD gains by going ARM. probably marketing and SW Eco system reasons. The x86 ISA decode penalty is a non issue these days. If AMD can move these parts through commodity channels and make their availability ubiquitous, they have a good chance of a 10 -20% market share. But execution s everything and that seems a big ask for AMD these days. Would also help if they went open with their freedom interconnect. What would also be interesting is repurposing the GCN for packet processing, ala IXP/Netronome

@Junko - The only logical conclusion to that question is that AMD feels that ARM provides something that x86 cannot. AMD is a member of the exclusive club of 2 that can make x86 processors so for it to give up all the advantage of the established ecosystem around x86 to move to ARM is a testament that they feel they can compete better with ARM CPUs.

They did try low power CPUs with bobcat but probably found the ARM CPUs to be much better at the low power level. At the high end where it is performance at any cost they will still bring out x86 cpus.
