If you want to bash the Vampire as an accelerator that's fine.
Not really, the Vampire cards are great piece of hardware.
However, the average person jumping in this thread is getting a polluted image of the Apollo core.
Or "nuanced", an image not glorified with only superlatives and hype.
The Vampire is using a SUB_SET of the full Apollo core because it is using a smaller FPGA and so features were removed. As described in a link a page or so ago, some reworking was done to make space for an FPU in the Vampire accelerator board. No sacrifices will need to be made for future boards with larger FGPAs.
Was there ever an FPGA running "the full Apollo core"?
Has anyone seen "the full Apollo core" run?
Does "the full Apollo core" even exist yet?
Will it ever? Or will "the full Apollo core" always be "the next big thing"? Remember, V2 was supposed to support "the full core", and V1 had the "limited edition" (known as Phoenix).
Time will tell.
Oh, did anyone else license Apollo Core yet?
