As the majority of our readers should be aware of, Apple’s A7 processor is the first mobile SoC to have adopted the 64-bit architecture. While this doesn’t offer a ton of benefits at this point in time, it’s still quite an achievement, and with the passage of time, you can be certain that more smartphones will feature 64-bit processors under the hood.
Given the fact that Samsung has been the one to manufacture the A7 processor, and also because Sammy has enough resources to heavily invest in R&D, there have been several reports suggesting that the Korean tech giant is already working on a 64-bit Exynos processor of its own. These rumors have started surfacing since last year, but there haven’t been any concrete bits of evidence to support these theories. Not until now.
Samsung’s 64-bit CPU Gets “Confirmed”
Up until now there hasn’t been a lot of proof to further strengthen the idea that Samsung is working on its own 64-bit processor. Sure, various officials have openly admitted that the manufacturer has this kind of SoC in the works, but if you’ve waited for harder evidence before letting yourself persuaded by this theory, then our latest findings might just do the trick.
IT Blogger Chocoberry has just dug out information on a mysterious Samsung quad-core SoC dubbed “GH7″, with ARMv8-A 64-bit architecture. The CPU has been spotted in a Linux kernel patch, and while GH7 appears to be implementing ARMv8 ISA, we can’t tell for certain whether the chip implements Samsung’s custom micro-architecture (which has also been rumored since Samsung’s Analyst Day, last year), or uses Cortex-A57 cores.
To give you a better understanding on how things work, the Apple A7 chip uses ARMv8-A instructions, but it has designed its own core/micro-architecture dubbed “Cyclone”. That’s not how it always works though, and a manufacturer can implement both the ARMv8-A instruction set, as well as the ARM Cortex-A57 cores in a SoC.
Unfortunately, the story is a bit light on details and we’re not sure how GH7 actually works. Information about the GPU, frequencies and other important factors is also missing. Nevertheless, this is the first public evidence of Samsung’s 64-bit SoC, and we’re fairly confident that we’ll get to see more of it in the future.
