Tema: Leopard + PowerMac G5 (64 bits)
Mi pregunta es la siguiente... me va variar mucho el rendimiento si instalo Leopard en mi PowerMac G5?? (dado que la G5 es 64bits y el Leopard está optimizado para 64 bits)
O la optimización es solo para Intel Core 2 Duo?

Matt, aguantá el pichí (como dice Cin), mirá lo que encontré Googleando:
"Slower on a Power Mac
We've been used to better performance as Mac OS X evolved from the Public Beta through version 10.3. With Tiger (10.4), that ended. And with Leopard, if these benchmark results are a fair indicator, there's a real performance hit.
Overall performance results for the Power Mac G5 with 1.25 GB of RAM show Tiger as the fastest with a score of 1013, 32-bit Leopard in second place (over 10% slower at 898), and 64-bit Leopard trailing that by an additional 5% (853). 64-bit Leopard tends to lag because 64-bit commands are larger and thus take longer to load under PowerPC architecture.
Looking at different components of the overall score, stream performance under 32-bit Leopard is better than under Tiger (by about 7%), but 64-bit Leopard is slower than Tiger.
Memory performance is almost identical for 32-bit and 64-bit Leopard, but about 7% behind Tiger, and floating point performance is best under Tiger, with 64-bit Leopard 5% behind and 32-bit Leopard 5% slower than that.
In short, for best performance, PowerPC Macs should stick with Tiger, and if you want to run Leopard on a G5 system, the additional overhead of a 64-bit OS seems to offset any advantage."
