Parallella Community

Hi I recently discovered this product while browsing online and have 2 questions. First it says that its a 64 core system but is the speed the same as a a normal computer with 64 cores? Also is there any way to add more ram? If this is as fast as an actual 64core computer I would love to use a few of these for 3d computer rendering at home but I would need 8gb of ram for each. Thanks.
