The New 3DS has 10MB of eDRAM (the same as the XBox 360), it's not like eDRAM is some magic do-all that dramatically alters a system's performance.
Nintendo just happens to like eDRAM as a memory architecture because they really, really (reeeeeeally) apparently hated the N64's RAM which had latency problems.
