Accelerator without ram performance.

Yes you did. Sorry. Cache seems to make huge difference even if ram is in side car. Wich is somewhat weird.

This makes the TF520 almost useless, imho. Why burn this card with 35MHz for a Result of 20% against an A500/A2000?

TF520 makes A500 1,7x faster than it originally was. Price is also very low, so it is very nice card for a price.

it's not weird at all.

every time your 020 board communicates with sidecar ram, it must do so over the Amiga 500 motherboard CPU bus, which is working only at the speed a 7mhz 68000 expects.

You can have a 200mph Ferrari, but if the speed limit on the road is 20mph, you won't get to the supermarket any faster than a lada.

Cache is a private race track for your Ferrari, you can go as fast as you want there.

It's not useless, it's a step in the direction of even better cards. That is one of the great things with the TerribleFire series of cards, they evolve over time, become better and better, yet every card is very affordable, so upgrading every now and then does not cost a small fortune. And you can reuse parts, lowering the cost even further.

It was a different story when I bought the Phase5 Blizzard 1230 III right before the 1230 IV came, back in 1994... :p
