Maybe i'm going crazy, so i've come to see if any of you guys have experienced something similar. Today I spent some time in my school's library (how novel), and noticed that they actually have some Macs in the computer lab, which unfortunatly, no one was using. Seems everyone has more attachment to the plethora of Dell's we have littering the place. So like a good Apple lover, I sat down by one of the Macs. They were 800mhz Quicksilver Powermacs with 512 RAM. Now, this was my first experience with a Powermac. But I was completly blown away. This computer which is a whole 600mhz slower than my eMac at home - nearly double the speed - actually felt faster than my eMac! I'm not talking about hardcore Photoshop rendering or anything. Just casual web browsing. The scrolling speed, genie effect, and app responsiveness was a GOOD deal faster than my eMac with nearly double the clock speed and twice the RAM. Even worse, the Powermac was running 10.2.4. As far as I recall, everyone said that Panther feels faster than Jaguar, so i'm even more confused. I thought that the speed might have to do with a better video card, or the L3 cache in the PowerMacs. However, after checking Apple History.com, it seems that the 800mhz Quicksilver had NO L3 cache, and shipped with a Radeon 7500 - the same card in my eMac. Now those of you who say that there is something wrong with my eMac - yes it is performing like a 1.4ghz eMac. My xbench score is 140, double that of an 800mhz Powermac. So my question remains, why the heck does the Powermac *feel* faster? Or at the very least, smoother in UI operations? One of the first thing I noticed when I got my eMac was how choopy it felt when scrolling up and down in Safari. The Powermac in comparison was smooth as butter. I'm at a loss here.
