Any other benchmarks out there

OK you dozen ARM server SoC vendors, if you have other numbers in the lab, let's hear them.

1000 mm2 Atom?

The footprint is way large. Remember when Atom was only 25 mm2; it's all grown up now, I guess.

Intel and arm both are leaders in their own space. But competition comes when one try to enter in others space. I guess its good forthe whole electronics indusstry if both continue doing good business.

I guess should be comparing package sizes, then it should be ~200 mm2 vs ~1000 mm2.

@Rick: GOOD article! On the power requirements for Avoton, how does it compare to equivalent ARM processor/s at the same clock frequency?

Regarding "dense forest of passives", this is something that can be addressed by the motherboard designers. Obviously we don't have the info on routing congestion in the vicinity of Avoton chip. Otherwise many  of the passives could have been embedded which adds some cost penalty.

compared to the fingernail, the chip cap looks to be enclosing about 50 mm^2, not 1,000.  50 is jelly bean size for a CPU or SOC these days.

@TanjB: Right you are, the big shift from server CPUs to SoCs is something you can see in the very size of the packages

@MP: I did not get as many specific power numbers as I wanted to see. Basically Intel just did perf/watt at the node level, no core to core and no deep dive across workloads yet.

ARM may still beat Intel when cost is considered

There's no doubt that Intel can beat ARM when using performance per Watt as a metric. However traditionally ARM beats Intel on cost. So in devices where best performance is not the goal (smartphones, tablets e.t.c) ARM won and will continue to win because of its lower cost.

It will be interesting to see who wins on the server front. Performance is obviously more crucial in servers....But the cost metric is also just as important.

Actually, performance per watt is probably more important to a degree to the server market than cost. Keep in mind that power is an ongoing expense while you only pay once for the chip - at least until Intel and the other chip companies can figure out a way to lease them...

Also, the CPU chip cost is only one component of the cost for a server, both in terms of dollars and watts. Do we know how different a server board BOM cost is between ARM and x86? Likewise, is the only significant power usage difference between those server boards the CPU itself?

NEXT UPCOMING BROADCAST

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.
