left picture shows "DBurst off" - the two can't be compared. Make sure that all caches and burst is on, install the latest setpatch, then run both tests again. Or better: Run AIBB and make modules, then use the "review mode" to compare the two cards in detail.

It's true that the SD-Ram controller of the 55.55MHz card is one clock cycle faster on writes, so it does have a chance to be faster on certain tests. However, the ACA1230-56 is syncronous, and that gives it advantages on chipram access. Further, it's even faster on NTSC machines, as the board frequency is multiplied: On PAL, it's 56,75MHz, and on NTSC, it's 57,27MHz.
