Are you a Sprint customer wondering which phone is faster, the HTC EVO Shift 4G or the Samsung Epic 4G? WireFly has put together a little video of their benchmark test.
WireFly used Smartbench 2010 to take both phones through standard benchmarking tests. Both phones did okay in the productivity department, but the Epic 4G basically smoked the EVO Shift 4G in the graphics/gaming department. No surprise there really.
The only reason to get an EVO Shift is if size is a concern. Otherwise, check out the Epic 4G.
