Stratix 10 SX SoCs feature hard processor system with 64 bit quad-core ARM Cortex-A53 processor available in all densities in addition to all the features of Stratix 10 GX devices.
Stratix 10 is the latest offering though (very new and expensive), more comparable to what Xilinx refers to as their "UltraScale+ MPSOCs", which are basically their Zynqs, using the UltraScale+ fabric as opposed to Artix/Kintex level stuff, and branded differently.
You can get affordable Cyclone V FPGA/ARM boards though, which are more comparable to the traditional "Zynq" series (dual ~1ghz 32bit cores, some DDR3, etc).
