Samsung seemingly preparing several variants of Galaxy S4.
Samsung's unannounced Galaxy S4 smartphone has made its first appearance in a benchmark listing, which seemingly confirms the device being powered by eight cores.
Outed by Antutu Benchmarks, a Korean variant (SHV-E300S) and an international variant (GT-I9500) are listed. According to the benchmark, the Galaxy S4 boasts Samsung's Exynos 5 Octa processor -- the world's first eight-core mobile processor -- clocked at 1.8GHz. It'll apparently launch with Android 4.2.1 Jelly Bean.
Other rumored features of the Galaxy S4 include an eight-core Mali-T658 GPU, 4.99-inch SuperAMOLED full HD display, at least 2 GB of RAM, a rear 13-megapixel camera and a front-facing 2-megapixel front facing snapper.
Although it failed to make an appearance at CES 2013, Samsung has confirmed the existence of the Galaxy S4 and said it won't launch until May at the earliest.
The device has previously been rumored to feature Samsung's eight-core processor, as well as sporting its flexible OLED display. As for the screen itself, if a Samsung CES 2013 roadmap is anything to go by, it's seemingly 4.99-inches and offers a full HD 1080p resolution.

If you guys need an editor I'll gladly take the job.
People don't "need" smartphones at all, they "want" them
...
This phone and everything about it falls into the "want" category
That "photo" is a rendering, and an old one at that. Nobody has a picture of the actual phone yet. They flashed the same rendering before the SGS3 came out, and it turned out to be totally different.
My old Nexus S disagrees with you, running JB perfectly smooth on >2 yo hardware. That goes to show that you don't NEED that kind of power.... but it's nice to have it, nonetheless.
A bit of research goes a long way...
