what am i looking at?
Looks like a FFT benchmark, but the guy who created AutoCAD.
It shows that a modern ARM chip performs like a 15-year old workstation.
Cortex A53 is slow than Pentium 4 in FFT using for signal processing.
>3.29s vs 0.846s
The A53 is the ultra lower power core, typically used as the "little" in big.LITTLE. It's no surprise that it's weak, especially in a cache heavy task like FFT. In fact I'm not even sure if it's an out of order architecture.
Clock for clock it's probably similar to that pentium 4 but it's also probably using like
sounds like it performs well
Honest question, why haven't powerful ARM chips like the Apple ones been released in a laptop form factor.
Imagine the battery life!
It's coming out fairly soon.
The obvious answer is lack of software. iOS/mobile/ARM platforms still lack a vast majority of desktop software that power users want.
Also, I don't know about their latest chips but IIRC the A9 or A10 could turbo up to like 11-12W. For phones it's fine because most people only use their phones for trivial stuff where a short boost would help with little impact on battery life and heat. It's basically the same as Intel's ultra low power Core Y processors, except phones have even less I/O and leaner RAM controllers, etc. that let them achieve lower idle and slightly lower platform power. I suspect there isn't a huge amount of power savings to be made if you put these chips under sustained desktop workloads, noticeable but not massive like people thing, probably.
Seriously? By who?
If it's priced sanely I'll be one of the first to buy and develop for.
>modern ARM chip
a53 is 5 years old
The software thing is very true, I think that's a huge reason why Samsung's thing where your phone acts as a computer didn't take off.
By Apple. Apple is replacing their laptops from intel to their own ARM cpus. It'll cut costs and bring fairly good performance for laptop use.
I'll leave this here.
>why haven't powerful ARM chips like the Apple ones been released in a laptop form factor.
Because only Apple makes them. But they'll release an ARM laptop soon enough, intcel's latest shenanigans handed them a good marketing strategy even.
Expect to see the "-40% performance in Intel" plastered on the screen on Apple's keynote when they introduce ARM laptops.
>ASIC Encoder
>one of the most common resource intensive tasks is handled by custom hardware
And that's a bad thing how? Do you also do encryption and media playback purely on the CPU with no custom hardware?
>Talk about CPU Arch end up in but accelerator hardware wins!.
Let's talk about CPU arch then, cause this is exactly where x86 gets its ass handed.
>+36% performance for arm in worst case scenario, +118% in best case
holy shit!
>Linear Scaling IPC ignore sub system memory, Avoid vector instructions.
Half of those are HW accelerated, the other use rarely used x86 instructions. In reality ARM just simply cannot keep up with x86 even at low power.
The snapdragon 835 for example has about half the 1T and nT performance of an apple A12 chip yet it performs somewhere on par with a celeron processor. In the end what makes ARM favorable for mobile devices is because it's dirt cheap and has somewhat better HW decoding efficiency than low power x86. This is why ARM has had virtually no success in the enterprise market.
This too, anything AVX and even older SSE is not shown here which is prized for general computing tasks.
99% of code is using only integer and string operations, the remaining code is better off running on a GPU. Let me see some benchmarks of that.
but at a fraction of the power costs
>where your phone acts as a computer
Microsoft did it first.

Kill yourself street shitter.
The biggest problem here is he's running emulated benchmarking software.... and he even mentions this

As long as you use 0 acceleration for everything, sending processors back to the '90s.
As long as you don't use x86 instructions that suck.
As long as your thermal envelope is not constrained whatsoever.
Then yeah, in that case arm ""can't compete"".
In the real world, you have a fanless, 5W tablet chip matching high power server chips with jet turbine cooling.
Like, if you literally take an *existing* A12 thread and compile with it, it'll give you 44% higher performance than a Xeon 8176 thread, even at over 1GHz disadvantage for the apple chip.
ARM has long surpassed x86 in terms of arch design, *but also* SOC implementations.
The only advantage at this point for x86 is legacy support by emulating motorola chips from the early '80s.
That and the fact that nobody until recently had the capacity and finances to produce high power arm chips with a workstation TDP. That's obviously changed.

Back to your shitting street iPajeet.
Nobody who actually needs a PC gives a shit about gimping it with smartphone hardware to gain 1 hour of battery life on top of the 9 they already get.
ARM laptops are typically low-quality trash like chromebooks built to be disposable.
Sorry intcel your pozzed cpus are no longer relevant.
>iNcel thinks his fruit toys were ever relevant
>no sources
Makes me think.
One-off supercomputer experiments are also fucking meaningless to the broader market. Let's talk about ARM products that actually exist and can be bought instead, like Cavium chips, and more specifically how nobody actually buys them.
Just because your smartphone can browse Facebook without lagging doesn't mean its shitty proprietary locked-down architecture should flourish elsewhere where it doesn't belong. Enjoy your 16-bit memory buses, fragmentation and benchmark-driven design.
>Nobody who actually needs a PC gives a shit about gimping it with arm hardware
*upgrading
A 4c8t 8559U barely beats an A12x (4fast cores, 4threads), even disregarding the power envelope of each chip, or the fact that the arm soc has all sorts of extra hardware on it taking space (cellular modem, wifi, ASICs for machine learning, etc. etc.).
That's like tying with your opponent while he has his hands and one leg tied.
And that's BEFORE mitigations that slash performance on Intel.

>mfw waiting for the death of x86
any day now
>can't wait for all CPU platforms to be locked down ARMshit!
kill yourself
Tell me, on the freedom focused x86, where can I buy a CPU with no rootkit (IME or PSP)?
>actively supporting duopolies instead of arm free market
all you socialist fucks are the same
>ARMshit
>free market
Good joke.
Name a single high end ARM phone in the last 10 years that you could take out of the box and install any OS you want. I'll wait.
Buy POWER9. No IME.
respects your freedom.
open source motherboards starting at $999
If they're equally locked, I might as well buy the faster, newer, more efficient architecture than be hamstrung by x86's legacy crap.
When was the last time you even needed to run 8080 software?
Lumia 950 (based microsoft)
May as well buy Power9
phoronix will review the blackbird in ~2weeks
>If they're equally locked
iToddlers aren't mentally ill, they're mentally void.
>if
Except they aren't equally locked. ARMshit is literal cancer and is 1000x more restrictive than x86 has been in its entire existence. Kill yourself street shitter.

shalom brother!
There are already ARM Windows 10 tablets out there, like the HP Envy x2. You can write regular old Win32 software for them.
