@Jay: Good points on how AMD's Hierofalcon is ahead of Intel's Rangeley in some ways --and needs to be since it will have to compete with a Rageley 2 late next year.
And agreed, as long as the core roughly meets the perf/watt needs and more importnatly is the ISA the OEM/user sw is written for, it's fine. Much of the differentiation is increasingly in SoC peripherals.
@Junko, That is the multi-million dollar question. Probably the development cost of a new x86 internal core did not result in an advantage in terms of performance/cost/power of an off the shelf ARM core. I am sure the AMD brass did their homework before making the switch.
This does validate what the ARM camp has been claiming in terms of architectural simplicity of ARMv8 architecture and its inherent advantage in building low power processors.
My guess is that AMD's plan is the following:
- Continue to push x86 based processors at the high end of the performance arena in the server and enterprise
- Push ARM based SoCs into markets where AMD has not had much success to begin with - this includes the embedded market as validated by the hiero-falcon announcement and low power servers using the freedom-fabric.
- Integrate their ARM and ATI graphics technology to gain a foothold in the lucrative mobile and eventually ultra-mobile segments.
Reasonable thinking in my mind as x86 has not had success in the lower two arenas inspite of Intel trying for so long.
@Tarra, yes, in theory, AMD giving up on "all the advantage of the established ecosystem around x86" does seem to indicate that they must have found something more compelling in ARM. The question is "what"?
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. moncler jackets 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.
I wonder if choice of processor cores will be any more important than choice of other components on the SoC. Rangeley does not have the 10G Ethernet backplane interface. On the other hand, Rangeley does have hardware encryption capable of 10Gbps throughput, 5 Gbps in the 15W part. Rangley also has VT-x and no mention was made of hardware virtualization features of the AMD chip's cores. These things could be more important than the processor core, paticularly for software-defined networking.
Sometimes I do forget that we still have AMD. This company is truly trying. My problem has been that AMD has good technology but poor marketing unit. They make nice products but they have a very bad branding strategy.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
