The ocs chip set have normal AGNUS, Chip 8371/8372 with 512k/1mb and 8375 chip are the ECS AGNUS, A500+ for example have this chip, and its capable have 2mb of chip. The chip DENISE is part of OCS or ECS chip set, OCS have the denise chip called 8362R6/R8, the R8 version is capable to show 64colors equal of the ecs chip set. The super denise is 8373 (found on A500+) and have all capacities of the denise chip, but have a lots of new resolutions, and full support of the EHB mode and the PCHG format (show 640x512xham6) is better, a very pretty game using ECS chipset is for example, Wasted Dreams or Hell Squad =) very pretty games
Cheers
