sigxcpu Posted March 14, 2006 Share Posted March 14, 2006 Hello, I've played with an iMac today, when I was at an Apple showroom to ask about MBPs ETA. It simply rocks. It moves much faster than my hacked OS X running on P4@3GHz (almost DTK configuration). I've played a lot with Photoshop CS2 (unde Rosetta) with a picture about 28000x42000 and it moved like a charm. Applied filters, everything was fast. Didn't feel the emulation. Now, I have the money, I have the wish, just waiting for that MBP to arrive in Eastern Europe Link to comment Share on other sites More sharing options...
Colonel Posted March 14, 2006 Share Posted March 14, 2006 you probably feel it running faster because the machines that Apple shows off are always the best. It was 1GHz more than your machine and I'm guessing more RAM. Did you get to try out a Mac Mini too? Link to comment Share on other sites More sharing options...
Pu7o Posted March 14, 2006 Share Posted March 14, 2006 you probably feel it running faster because the machines that Apple shows off are always the best. It was 1GHz more than your machine and I'm guessing more RAM. Did you get to try out a Mac Mini too? That'd be interesting, considering the iMac I have was originally on display at the apple store (it was the last one they had!). It only has 512MB of RAM and a regular 1.83GHz dual-core processor though. Link to comment Share on other sites More sharing options...
aqualeviathan Posted March 14, 2006 Share Posted March 14, 2006 It's not 1 ghz more since a dual core 2ghz processor is NOT the same (or as fast as) a 4 ghz processor. Link to comment Share on other sites More sharing options...
Colonel Posted March 14, 2006 Share Posted March 14, 2006 wouldn't two 2GHz processors equal 4GHz? Link to comment Share on other sites More sharing options...

sigxcpu Posted March 15, 2006 Author Share Posted March 15, 2006 Multi CPU systems just bring responsivness, not raw speed. That is, when more than one process/thread is running the system overall seems fast. For a one thread app, a single CPU with a high freq is the best choice. @colonels: wrong. It is not an Apple store, it's just a showroom called Mac Gallery (in Bucharest, Romania). They are using of-the-shelf samples. Anyway, I don't think Apple uses different hardware platforms for showing capabilities of a model. Link to comment Share on other sites More sharing options...
Ouch Posted March 15, 2006 Share Posted March 15, 2006 Doubling the number of cpu's in a system doesn't double the speed of an application even a multithreaded one because you have to take into account communications overheads between the various cpu's.

Altimit Posted March 17, 2006 Share Posted March 17, 2006 Plus you need to take into consideration that the new Macs' dual core processor is not two processors. Dual Core does not equal dual processors. Link to comment Share on other sites More sharing options...
