I’ll be the first to admit that some conversations go way over my simple head, such as the discussion that followed the launch of Apple’s 64-bit A7 processor. This: “A64 allows 32 bit VMs to operate within a 64 bit hypervisor.” What? I do, however, understand "willy-waving" (hee hee).
That's pretty much what Qualcomm is saying too, describing Apple's 64-bit claims as nothing more than a “marketing gimmick”, while in the same breath confirming that it’s planning a 64-bit processor as well. Brilliant.
We’re perusing words from the mouth of Anand Chandrasekher, Qualcomm’s senior vice president and chief marketing officer, ably typed up by the guys at Techworld.
"I know there's a lot of noise because Apple did [64-bit] on their A7," begins Chandrasekher. "I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that."
Indeed, the marketing guys proudly proclaim that the iPhone 5S is the “first 64-bit smartphone in the world”, boasting “desktop-class architecture in a super-slim phone”, though we’re not given any real-world indication of what that means for Joe Average. Does the iPhone 5S really need a 64-bit processor?
Not according to Chandrasekher. He says one of the benefits is memory addressability beyond 4GB, while the iPhone 5S has just 1GB of DRAM.
But having said all that, Qualcomm will of course produce a 64-bit chip of its own. Chandrasekher explains: “From an engineering efficiency standpoint it just makes sense to go do that. Particularly the OS guys will want it at some point in time.”
