Can Cyclone V SOC achieve 50 MB/s eMMC R/W performance - same as Arria 10 SOC eMMC - with same clock speed and data width?

This question is about the eMMC read and write speed of the Cyclone V and the Arria 10 (SoC FPGA's). Both specify 8 bits wide and a clock of 50 MHz. There is also a mention of a 25 Mbytes/sec speed...
