this is an interesting part:
LEVEL 3 CACHE BETTER?
Another often asked question is, "Should I get CPU upgrade with the fastest clock speed or go for a slower clock speed version with L3 cache?" The short answer: "It depends."
It depends on what applications you are running. In past testing, certain applications (such as Photoshop) thrived on L3 cache. A slower CPU with L3 cache (7455 or 7457) would often beat a faster CPU with only L2 cache (7447A) when running our test action sets. But this discussion has recently become academic since the upgrades with L3 cache are being phased out. In a very short time, they will no longer be available unless leftover in some resellers inventory.
Also, in our most recent tests, the fastest 7455 (1.42GHz with L3 cache) could not match the speed of the fastest 7447A (2.0GHz with L2 cache). That and the fact that 7447As generate less heat and use less power, we have to recomend the 7447A based upgrades like the one we tested in this article.
Then again, if you can get a good price on a G4/1.4GHz 7455 or 7457 based upgrade, it would give a G4/1.8GHz 7447A a close race on all our test apps and beat it running Photoshop.Proud member of the Belgian Amiga Club since 2003
