Pi4 will come in four different flavours.

The Pi4 Maker Lite, is the cheapest. Aiming to be around the same cost as the current Pi3. It will have a quad-core SoC with frequency scaling up to 2GHz, 1G RAM, low end FPGA and no SATA, secondary HDMI or eMMC.
– quad-core SoC @ 2GHz
– 1GB RAM
– Low end FPGA
– No SATA
– No secondary HDMI
– No eMMC

The Pi4 Maker will increase ram to 2G and add in 4G eMMC.
– quad-core SoC @ 2GHz
– 2GB RAM
– Low end FPGA
– No SATA
– No secondary HDMI
– 4G eMMC

Then there’s the Pi4 Pro Lite which keeps the 2G RAM and 4G eMMC, but moves to a hexa-core SoC running at 3GHz and faster FPGA along with SATA and secondary HDMI ports.
– 6-core SoC @ 3GHz
– 2GB RAM
– FPGA
– SATA
– Secondary HDMI
– 4GB eMMC

And finally the Pi4 Pro will have 4G RAM and 8G eMMC.
– 6-core SoC @ 3GHz
– 4GB RAM
– FPGA
– SATA
– Secondary HDMI
– 8GB eMMC
