P1V - LE sizes

Thought I would just have a look to see what LE sizes are used for some of the P1V...
I had previously determined the video and the cog. These are using the De0-Nano (Cyclone IV) and Quartus 16.0).
It would be interesting to compare the real P1 transistor/gate count with the P1V Verilog version. I am sure Chip's handcrafted logic would have done a way better job

8x Cog with 8x Video, 48KB Hub (P1V unscrambled)... * 14,646 - DE0-nano (EP4CE22F17C6) * 14,613 - DE2-115 (EP4CE115F29C7) * 8,440 ALMs of 9,430 - BeMicroCV (5CEFA2F23C8) * ?????? - MAX10M16SCE144C8G LE's used (EP4CE22xxx)... 4x Cog, no Video... * 6921 - 4 cogs, no video * 216 - 1x video * 1534 - 1 cog, no video ALU (1x)... * 205 - overhead * 149 - add/sub/etc instructions * 121 - mins/etc instructions * 288 - rev/etc instructions VID (1x)... * 216 CTR (2x)... * 472
