Syzygy EGTB is significantly smaller than any existent [[Endgame Tablebases#DTM|DTM]] EGTB. It is 7 times as small as Gaviota for 5 men, 8 times as small as Nalimov for 6 men, 8 times as small as Lomonosov for 7 men. However, when all DTM EGTBs have full data of two sides, Syzygy EGTB omits data of one side for DTZ data to save space. [[Ronald de Man]] estimated if keep them all, the Syzygy's 6 men size may increase 158 GB, become 307 GB in total, double on size, be 4 times as small as Nalimov 6 men.

On the first release (Apr 01, 2013) the generator was ready to generate all endgames up to 6 men. The generation It is multithreaded multithreading and processes completely in RAM. To generate all 6 men, it requires a system with at least 32 GB of RAM and may run in 5 days (the period was measured with a computer 6-core i3930K @ 4.2Ghz, 64 GB).

After the completion of 7-man, many people start being curious about the feasibleness of building 8-man. Ronald de Man made an estimation that task requires computers with 64 TB RAM and 2000 TB hard disks<ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=74185&sid=016570559fa97e785404dd65020c0ad6&start=20#p848245 Re: What is the best way to obtain the 7-piece tablebases?] by [[Ronald de Man|syzygy]], [[CCC]], June 22, 2020</ref> (cost costed about $640K and $40K respectively in 2020 <ref>[http://talkchess.com/forum3/viewtopic.php?t=74185&start=30#p848394 Re: What is the best way to obtain the 7-piece tablebases?] by [[Dann Corbit]], [[CCC]], June 23, 2020</ref>).
