It was obvious that the involved analyst was talking about linux as a popular desktop platform. The server world is dominated by linux.

Running linux may solve the OS problem, but software will still have to be recompiled and tweaked for a new hardware platform. If a company has invested in any commercial software for x86 linux, they will probably have to repurchase the Arm version of it.

for the server market, power wont always be the decideing factor, there is also cost to run the servers, and arm is significantly lower power than intel, and as for speed, arm is getting faster and faster without the nead of an elaborate heat sync.

this could honestly be the begining of a power shift for arm and intel.

if arm succedes in the server market, it will cross to the desktop, now, 1 arm cpu wont really be powerfull enough there, i was trying to figure out how much the cpus cost, but google has been failing me there, however i did come across this, "$0.10 per processor shipped" its the cost that they pay arm on average per chip, or how much they get, so im assumeing that r&d for chips is sinificantly less of a cost than for intel and amd,

now im assumeing that you can slap 4 of these quad core ones into a single computer and come out less than a single quad form intel.

an essentially noiseless cpu with low heat? 16 threads? ass time evolves its obvious that applications WILL be threaded, once that happens, will intel/amd be able to compete with what arm has to offer? they may not be able to compete on clock per clock, but on the same power draw of a quad core intel sandy bridge, or amd phenom II

intell being 95 watt
amd being 125 watt
arm being 5 watt

you can fit 19-25 cpus in a pc at same powerdraw, space may be an issue there though, and no idea on cost,

"These chips will consume about 90-percent less energy, take up around 90-percent less space and have a lower overall cost of ownership compared to Intel's mid-range server processors."

IF this is true, then is ARM really 10x better than Intel? If so, Intel needs to do more than have better manufacturing. Can someone elaborate?
(I personally still see HP going down hill from a R&D powerhouse to a repackaging company).
thanks!

"IF this is true, then is ARM really 10x better than Intel?" - Yes, they really are, at least in terms of power-to-performance, but only up to a point. The higher-end Intel processors have a higher absolute performance for each core, so if the best possible performance for a single program is your goal, then Intel is the better solution.

A *lot* of server processes are entirely gated by network speed, like web servers, for example. In those cases, a large number of low-power cores can help with making the system as responsive as possible under heavy load.

On the other hand, database servers are typically a lot more CPU-power-bound, so the fastest possible processor is a better fit there.

@Alidan: the Cortex A9 core is clock to clock comparable with Atom processors, next generation Cortex A15 coming out in second half next year will be clock to clock comparable with Core processors, and the generation after that coming in late 2013/early 2014 will be clock to clock comparable with Sandy/Ivy Bridge. As always though ARM processor are design with a maximum TDP per core at 1GHz of 500mW, they typically use far less power than that though. Every time you double the frequency you can in general just double the TDP as well.

And btw, the $0.10 is the license fee ARM manufacturers pay ARM for use of their IP per core shipped.

The major difference between ARM and Intel lies in their prospected roadmaps. ARM expects at least a doubling in processor power every for at least the next 5 years in the same power envelope. Intel expect a maximum 20% rise in their processing power per year on average. So even though Intel had an enormous head start 3 years ago, they are really being leapfrogged.

when i say 10 cents, im talking about what they pay arm. as i have gone into lenghy discussions with people in the past over what makes a cpu cost so much. we came to the conclution that the bulk of the cpu cost deals with r&d, with a 10 cents r&d cost per chip on arm, i cant see ir being all to much more expensive than manufacture cost lets say it costs 50000 to manufacture the chips, and you have a yeild of about 1000, that would be about 50.10$ to make. proffit would come in at about 10$ a chip markup, and a further 10$ by whoever buys it to sell, or put in a device. all in all 70$

im assumeing all this of coarse, because the yeild in a batch may cost less to produce, and may have higher yeilds, as based the 50k off a figure i heard on i think a amd fabrication.

Given that you can actually buy top of the range ARM SoC's in single units for less than $70 from electronic retailers, I think it's safe to say that your estimate is pretty far off. One figure I hear again and again is that the "sweet spot" lands these SoC's between $15-22 per unit in 1K batches.

"Clock for Clock"...are we talking integer operations? floating point operations? AVX?? You can't just say 1 processor is "faster" than another "clock for clock" without telling exactly what type of instruction/operation is used. For ARM to actually compete against Intel in the desktop space, they will have to start adding support for multimedia instruction sets.

People seem to forget that ARM is still just 32bit. Server platforms have been 64bit for over a decade. What kind of workloads will these things be able to run without significant rewrite?

How many ARM chips will it take to equal the performance of a 95 Watt Intel 2700K 3.9Ghz Quad Core? How many glue logic/chips will you need to link dozens of ARM chips? There are so many features ARM needs to add to compete in the server market that it won't be small and cool chips anymore.

Intel 2700K (Quad core) @ 3.4Ghz - 128,300 MIPS
ARM Cortex-A15 (Quad core) @ 2.5GHz - 35,000 MIPS
ARM Cortex A9 (Dual core) @ 1.0GHz - 5,000 MIPS

MIPS isn't very accurate but it's one metric.

Cortex-A15 isn't even out yet and you're looking at 4 of them to equal a $300 Intel CPU.

I've seen a 16 X Cortex-A9 @600Mhz server that uses only 80 Watts but that's only 1/3 of the compute power combined.

By the time ARM adds 64bit capability it will be competing with 14nm Haswell.
 
The platform of choice depends on what exactly your trying to do. ARM CPU's are weak, really really weak in processing power, but their also extremely cheap, small, have dramatically reduced cooling requirements and above all else use an incredibly small amount of power. Intel's x86 CPU's are very powerful yet require higher cooling and use more power per unit.

So as a engineer I have to choose the best platform for whatever workload I'm engineering for. When you need an incredible amount of distributed parallel operations at once, yet the actual execution speed isn't a big concern (wide and shallow performance footprint) then something like ARM makes sense. If you need a smaller amount of operations but those operations execution speed is time sensitive (narrow and deep), then a x86 platform makes sense. And if you need a large amount of parallel operations that are connected and time sensitive (wide and deep) then something like SPARC is a better option.

It's impossible to state that one architecture is better then another without including the context of the comparison.

If the ARM chips have AES and SHA hardware, they could make for some really nice network hardware (high end routers and probes) and small business servers.
 


Via Nano already does this, although their dual core version has been ridiculously hard to get a hold of these days. Really low power, high performance (relative to power usage) and small foot print, ideal for a small server or network device.
