Chandrasekher's comments come back to bite him in the butt

It looks as though comments made by Anand Chandrasekher, SVP and CMO at Qualcomm, have really come back to bite him, as he has been reassigned within the company.
According to a statement provided to CNET, "Anand Chandrasekher, is moving to a new role leading our exploration of certain enterprise related initiatives. Anand will continue to report to Steve Mollenkopf, COO and President of Qualcomm. This will be effective immediately.”
The ruckus all started earlier this month when Chandrasekher was rather blunt in his assessment of Apple’s new 64-bit A7 processor that powers the iPhone 5S along with the upcoming iPad Air and iPad mini with Retina Display.
Chandrasekher commented, "I know there's a lot of noise because Apple did [64-bit] on their A7. I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that.”
He went on to add, "Predominantly... you need it for memory addressability beyond 4GB. That's it. You don't really need it for performance, and the kinds of applications that 64-bit get used in mostly are large, server-class applications."
It didn’t take long for the comments to stir up a bit of controversy in the tech community, and a Qualcomm spokesman later attempted to distance the company from the statements regarding the relevance of 64-bit processors in mobile devices:
The comments made by Anand Chandrasekher, Qualcomm CMO, about 64-bit computing were inaccurate. The mobile hardware and software ecosystem is already moving in the direction of 64-bit; and, the evolution to 64-bit brings desktop class capabilities and user experiences to mobile, as well as enabling mobile processors and software to run new classes of computing devices.
It is unknown what role Chandrasekher currently holds at Qualcomm, but CNET reports that he has been booted from the company’s leadership page.

Memory addressing isn't the only reason for 64-bit. There are still demonstrable benefits even though it has just 1GB of system memory.

It isn't a doubling in performance, but gaining a ~40%-60% increase in performance simply by moving an app from 32-bit to 64-bit isn't what you'd call useless either. Several music and video creation apps on iOS have already dramatically improved performance on the same hardware by switching over. It will benefit all hardware moving forward even before they hit over 4GB of system memory.

While you're right, the big problem remains, 64bit is mostly memory related. Of course, 64bit nubmers will be calculated faster on a 64bit processor than on a 32bit processor. So specific programs, compiled for 64bit systems, benefit from it.
But don't forget, that a 64bit number is also twice as large as a 32bit number. So 64bit programs (if they take advantage of 64bit) tend to consume more RAM than 32bit programs. Thus multitasking will become worse, if the amount of RAM remained unchanged.

So what the CMO said, was wrong. What Apple did was the right step. And there's no need to have 4GB RAM to benefit from 64bit. But not increasing RAM was a poor decision.

PS: Take the numbers on Anandtech with a grain of salt. We don't have the source code and thus don't know if Apple hasn't optimized the 64bit code outside of just switching to 64bit mode.

Those performance numbers are garbage. This will hamper performance in a number of ways. The least of which not being the laziness granted in the way of memory optimization nad file system bloat.

That is a terrible argument for two reasons, one is that there have already been performance improvements in actual applications running on the same hardware just by moving over from a 32-bit version to 64. The other is that the "laziness" afforded by more capable hardware is an awful excuse for... anything really.

Would you rather things stopped improving so that developers have to work harder at optimizing software towards an inferior result? That makes no sense.

A 40-60% increase claim is garbage.

Also that depends on what you definition of improving is. Bloated, unoptimized fart apps with more animation than substance is not an improvement to me. What app are you running on your phone that needs over 2 gigs of memory space.

And that is the only reason for moving to 64 bit hardware. There are better ways of gaining performance, PAE for greater than 4GB total memory addresses, no current 64 bit software, and no other features that require 64 bit architecture.

Excellent strawman there. "Fart apps" are like the Godwin's Law for mobile.

Again, music and video editing apps are what have seen the most improvement so far. Real-time processing that used to add chop are smoother after the transition. The same has happened with recompiled apps like web and media browsers. Again, these aren't hypotheticals, these are happening right now.

Another positive side effect is that it allows for greater performance in a more efficient package with greater battery life. An A7 with half the system RAM, half the clock speed, and half the battery size is faster with longer battery life than a GN3. Won't it be great when that level of efficiency and performance scales up and is available in larger devices? A 6" phablet with that level of power and efficiency would be an absolute powerhouse.

I see you have clearly never done any work at all in a kernel, any low level development, or many performance critical applications such as game engines where 64-bit operations are extremely common, and you will see a noticeable improvement when properly programmed.

There are tons of uses for 64-bit programming:
-Virtual address space ranges
-IO (seek offsets have been 64-bit values since forever ago)
-Time related functionality (64-bit performance counters)
-Unique identifiers (Many counters can roll over too easily on 32-bit)
-If the hardware doesn't already contain 128-bit SIMD functionality (which according to you, why would they?) you already also gain the ability to read (and write) twice as much memory over the bus at a time - simple operations like memcpy will see an immediate improvement (not 2x, but a big leap forward)
-64 bit registers make atomic operations on 64-bit data values actually possible, which reduces the necessity to perform multiple expensive interlocked operations and lock contention.

The list goes on. I don't know why you don't acknowledge these scenarios unless you simply do not know they exist.

Well, there is a simple cure for you.

Keep your current smartphone (if you have one) and never upgrade it.

Apple has let the genie out of the bottle by implementing their A7. To compete and move forward, everybody else is doing the same. So like it or lump it - 64-bit is coming. So stick your head in the sand and hope you never have to buy a 64-bit device or you can stay on the bleeding edge. The choice is yours.

Just remember though:
When you stick your head in the sand - your ass is sticking up in the air.

Oh heaven's man, nobody is saying 64 bit has no benefit. The only point of contention is selling it as a marketable feature. I have the 5S and it's super smooth, but I can't say that there's a noticeable difference from my 5 with both on iOS 7.

I don't have the extensive knowledge of low level programming required to make an extensive argument for or against 64 bit, but I do know the single largest benefit is addressing larger amounts of RAM and simplifying larger mathematical operations. I would posit that only a small fraction of iOS users utilize Apps that benefit from these improvements.

I agree that it's a step in the right direction. But I think it's silly to paint Apple as being so innovative when it was the next natural evolution of mobile processors. Everybody and their brother (in the tech community) knew it was coming and while Apple beat everyone's expectations by 6 months to a year, it's not a game changer so lets' stop acting like it is.
