Apple generally doesn’t reveal the actual specifications of its iPhones and this year also it didn’t wasted time on revealing the same. Though not much important for most of the Apple lovers, an image on Geekbench was spotted as per which the iPhone 7 Plus has 3GB of RAM. 
Before the actual launch, there was a lot confusion about the specifications of the new iPhone 7 and 7 Plus. While the iPhone 7 features 12 Megapixel rear camera, the 7 Plus comes with a Dual-Camera setup which certainly requires more power to process images. Apple claimed at the launch event that the dual-camera set up will enable users to optically zoom images both before and after the image has been captured. Moreover, Apple is also allegedly working on an update which will bring the famous bokeh effect. So to process images more efficiently, the phone requires better RAM management.

On the other hand, iPhone 7 seems to have 2GB RAM, which Apple believes should be just fine for the device to operate smoothly. Further, iPhone 7 doesn’t have that dual-camera set up so the device doesn’t need extra ram to process high-quality pictures.
Also, according to the reports, Geekbench still doesn’t count Apple’s low-power high efficiency scores of the A10 fusion chip so one should not rely on the Processor speed results here.
