This is ridiculous. Who installs a cpu card without fast ram??? I don't know anyone who uses a 040 without fastram. Do you use your 030s without fastram?
I never felt BlizzardIV 030/50 faster than A3640 in demos... in fact many won't work on a 030.
I'm not sure what you're talking about, but I'm talking about the RAM that's on the turboboard itself. Of course, I have the usual 16MB A4000 mobo RAM, but with A3640 it still feels subjectively slower than 1230 MKIV. I don't have any benchies, I simply remember quite a few demos that were slow, but still enjoyable on 030/50 that are nothing more than a slideshow on A3640. I'm not saying the A3640 is slower across the board - it might well be faster in WB and serious apps, but that's more difficult to judge.
