A spokesperson said the statements were "inaccurate"

Qualcomm suddenly has an about-face regarding Apple's 64-bit A7 processor, which a company executive called a "marketing gimmick" just last week.

Anand Chandrasekher -- senior vice president and chief marketing officer at Qualcomm -- said last week that Apple's 64-bit processor in the new iPhone 5S doesn't offer a big enough reason for consumers to upgrade because 64-bit chips are needed for memory addressability beyond 4GB, and the iPhone 5S has only 1GB of DRAM. Hence, he concluded that 64-bit processors are not relevant in today's smartphones and tablets. 

"I know there's a lot of noise because Apple did [64-bit] on their A7," said Chandrasekher. "I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that."

However, Qualcomm is backtracking on those comments and now says that 64-bit processors are a necessary part of the future of mobile computing. 

“The comments made by Anand Chandrasekher, Qualcomm CMO, about 64-bit computing were inaccurate,” said a Qualcomm spokesperson. “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.”

Qualcomm works closely with Apple and supplies modems for iPhones and iPads. Also, both companies design chips based on ARM architecture. 

More specifically, the A7 chip is based on the ARMv8 instruction set, which is said to boost performance through quicker mathematical and security tasks. It also eliminates the inefficiencies in older ARM instructions, but some wonder how much credit the 64-bit processor can take for the heightened performance. 

Apple released its iPhone 5S last month, which runs $199/$299/$399 for 16GB/32GB/64GB respectively. 

Qualcomm provides its Snapdragon chips for Android and Windows Phone smartphones and tablets. It even plans to continue investing in chips made for Windows RT, which is a mobile version of Windows 8 that runs on ARM-based chips and has been criticized for failing to produce a full Windows 8 experience (it can't run legacy apps).  

Qualcomm said it plans to offer a 64-bit processor in the future to keep up with chip designs and even cut manufacturing costs, but there's no set release date.

It's the best explanation of why and how 64-bit computing is beneficial to anybody.

(sorry Anand, I haven't seen a write-up on this site that's nearly as thorough as this one on ARS: )

In short, for most applications, it's not a processors "64-bitness" that makes it faster than the 32-bit equivalent. It's other features that were changed/improved/added to the processor.

Yes, today's 64-bit processors are faster than yesterday's 32-bit processors, but it's not because they're 64-bit. That's like saying "blue cars are faster than red cars" because you bought a blue Mustang GT to replace a red Prius.

Except no, no it isn't. That's absolutely and entirely incorrect.

64-bit, of ITSELF, fundamentally increases performance of numerous operations - as you would know if you'd read the Anandtech piece on it:

And it so happens that the apps which most need additional performance (encryption / gaming / advanced 3D) are those which benefit the most from 64-bit.

Now, the move to the 64-bit architecture ALSO gave Apple massive performance gains, but that doesn't mean that 64-bit of itself isn't responsible for performance gain.

Thus your 'colour' example is totally wide of the mark.
