What about the processor in Lumia 840, the real powerhouse of Smartphones ???
Sure, Snapdragon 4** processors shouldn't be used in High mid range device( Lumia 840), Snapdragon 610 hasn't been used in any device till now so I think Microsoft won't use it in Lumia 840, Snapdragon 615 is sluggish Cortex A53 Octa core processor that heats too much and is not battery efficient for a mid range device, it would be nice to see Lumia 840 with powerful octa core Snapdragon 620 (Quad Cortex A72+ Quad Cortex A53) processor which is on par for performance with Snapdragon 800 series old processors. There are also rumours on the internet that LG Nexus 5 would come with Snapdragon 620 processor in late 2015.
What do you other Lumia users think about this?
