Samsung Mobile Business exec advises 64-Bit Chips are coming to new smartphones

Samsung with Google
With the launch of the iPhone 5s on Wednesday morning, Apple sparked a new battlefront for smartphone manufacturers – 32-bit vs 64-bit CPUs – and Samsung is keen to follow their lead.

Speaking to the Korean Times, Samsung’s mobile business chief Shin Jong-kyun advised

Not in the shortest time. But yes, our next smartphones will have 64-bit processing functionality.

It’s not promising the next Galaxy device will run a 64-bit processor but it will come soon enough.

It’s really not that big a revelation, based on recent announcements from ARM regarding their upcoming ARMv8 architecture, which will see Cortex A-53 and A-57 SOC architecture licensed to companies such as Qualcomm and Nvidia, with Intel also surely hard at work on this next generation of SOCs.

With 64-bit CPUs pretty much the standard in desktop and laptop computers, the architecture would be the natural progresion for Smartphones as well. Whether we see the 64-bit CPUs in a Samsung manufactured Exynos or a Qualcomm manufactured Snapdragon is the next question.

Dan is a die-hard Android fan. Some might even call him a lunatic. He's been an Android user since Android was a thing, and if there's a phone that's run Android, chances are he owns it (his Nexus collection is second-to-none) or has used it.

Dan's dedication to Ausdroid is without question, and he has represented us at some of the biggest international events in our industry including Google I/O, Mobile World Congress, CES and IFA.

This will eventually lead to the death of 32-bit browsers. Yaaayy!

The release of the new iPhone provoked a bit of a discussion on 64-bit processors with a friend of mine the other day. My understanding is that 64-bit processors only have an advantage when you have more than 4GB of RAM to address, as a 32-bit can only address up to 4GB. He argues that there is some advantage to a 64-bit processor even without that sort of RAM, e.g. the Nintendo 64 wouldn’t have anywhere near 4GB RAM and Nintendo saw fit to making it a 64-bit processor! However, if there is an advantage why haven’t chip companies done… Read more »

I’ll give you some generalisations about 64-bit – some may apply: 1. “True 64-bit” usually means more memory is consumed, as individual instructions would be 8 bytes instead of 4 bytes. This applies mostly to RISC processors such as ARM – for x86 this was more complex. Of course ARM already has a mode where some 32-bit processors run 16-bit instructions (called Thumb mode) specifically to keep memory usage lower so there’s no reason to expect that ARM 64-bit processors _must_ use 64-bit instructions all the time. Of course not using 64-bit instructions means any benefits are limited. 2. As… Read more »

Programs are larger as they need to fit in 64 bit space rather than 32. The 4gb ram issue isn’t going to crop up in the mobile world for a few years. Basically though, 64 bit is the future and will be needed at some point down the track. There are some advantages to the instruction set (on-board encryption for example) as well, but basically just future proofing from the reading I’ve done on the subject.

we are already hitting 3gb ram in new phones/tabs so I reckon 4gb will be Xmas time.

Firstly the N64 didn’t have a 64 bit CPU, it was the width of part of the graphics processor. Consider also MMX/SSE on your old Pentium 3 it had 128 bit vector processing. It was still a 32 bit CPU.

This is exactly what I wanted to know… I imagine the instruction sets work better or the data pipelines can be shrunk but I always assumed the benefit was primarily for RAM addressing
