Orchid Turbo EGA
The Orchid Turbo EGA was a rather unique expansion card that combined Orchid's TinyTurbo 286 accelerator and their EGA card into one solution. It came with an onboard 8 KB cache.

The Turbo EGA supported the standard 640 x 350 in 16 colours from a palette of 64, with full backward-compatibility to MDA, CGA and Hercules standards. The EGA BIOS was claimed to be 300% faster than the IBM EGA one.
The TinyTurbo 286 side of the Turbo EGA replaced the Intel 8088 processor via a ribbon cable into the CPU socket, providing your PC with an 80286 running at 7.2 MHz. It could also be fitted with an Intel 80287 math coprocessor. A toggle switch on the backplate could be used to switch between the 80286 and 8088 (which you reinstalled onto the TurboEGA board) for compatibility.
Board Revisions
I have no information on the various board revisions on the Orchid Turbo EGA card.
Competition
In 1986, competition wasn't huge, though some prominent companies were producing competitive graphics offerings to IBM's standard cards that were much more expensive, including Paradise Systems and Boca Research.
