Core 2 Duo vs PowerPC, in laptops

After all, if you are considering upgrading your old computer to one of the new MacBook Pros you probably do not want to do it from a Core Duo model that is approximately one year old. Instead, surely as a laptop user you are considering doing it from a PowerBook or even an iBook. Naturally in this case you will be interested in the performance improvement that you will get with one of the new MacBook Pro Core 2 Duo over the older models, especially when it comes to applications that do not yet work natively on processor-based Macs. Intel. Are there any performance impacts caused by the Rosetta emulation or is the performance increase of the Core 2 Duo sufficient to offset it?

In our initial tests, we found that running Rosetta applications on Mac OS X versions prior to 10.4.8 may experience some performance impact compared to running natively on PowerPC-based notebooks, especially MacBooks. since its graphics system borrows part of the main memory of the system and therefore does not offer a dedicated acceleration. Of course, these performance differences become more apparent when it comes to comparing the performance of Core 2 Duo laptops to higher-end systems based on PowerPC G5 processors.

However, with the latest batch of laptops based on Core 2 Duo processors we have verified that the performance in applications such as Adobe Photoshop or Elements (for the MacBook Pro and MacBook, respectively) offers a more agile response than we would obtain when running them on the old PowerBook or iBook (especially in this second case).
