So how is this different from MiSTer FPGA [1]? [1] https://mister-devel.github.io/MkDocs_MiSTer/ https://mister-devel.github.io/MkDocs_MiSTer/

You can't carry a MiSTer in your Pocket, but you can Dock a Pocket. It doesn't support a few power-hungry systems supported by MiSTer. MiSTer doesn't support OG physical carts.

  What about the actual FPGA specs? Is it more power efficient per LUT? A newer generation or the same generation but a smaller chip?

    The Pocket has an FPGA from the same series as the MiSTer, but it's a lower-end model that's optimized more for power consumption. Most notably, it's missing the 800 MHz ARM core (meaning that it runs a custom "OS" off of a microcontroller rather than Linux like the MiSTer), and it has a bit less than half the amount of logic elements. This means that 16-bit console emulation is about the highest you can go on the Pocket, while the MiSTer can emulate the Playstation, Saturn, and N64.

I’ve pasted the specs below, but in my opinion the biggest difference is that the OpenFPGA - in its Analogue Pocket form - is an end-user friendly target. MiSTer is more “enthusiast-friendly” with more options and upgrades (including an recommended add-on to the basic kit). MiSTer “tech specs”: Intel/Altera Cyclone V SE (5CSEBA6U23I7) FPGA SoC with 110,000LE (41,500ALM) and 5,570Kbit of Block RAM. ARM Cortex A9 dual-core CPU at 800MHz. HDMI video and audio allowing easy connectivity to any modern monitor/TV. 1GB of DDR3 RAM that is directly available to both ARM and FPGA. High-speed ARM <-> FPGA interconnect due to both being in the same chip. OpenFPGA specs: Intel/Altera Cyclone V FPGA 49K logic elements and 3.4Mbit BRAM Intel/Altera Cyclone 10 15K logic elements 2x independently addressable 16MB cellular RAM (128Mbit x 16) 32MB low latency memory 1x synchronous DRAM 64MB (32Mbit x 16) 1x asynchronous SRAM 256KB (128Kbit x 16)
