Been busy updating my computer lately so I have not been posting. Sorry to anyone missing my posts. I upgraded from a 2009 Mac Pro to a just released 2013 iMac and was worried that going from dual quadcore processors to a faster single quadcore processor was going to be a downgrade even though the new computer has faster individual cores. (Click the image to see it larger.)
The old machine has 8 cores each capable of 2.6 GHz. The new machine has 4 cores running at 3.5 GHz. Here’s the simple math:
8 x 2.26 = 18.08
4 x 3.5 = 14
So the older machine should be faster by about 25% when firing on all cores. Since many processes only use a single core I was willing to be slower when doing relatively rare activities such as converting large video files. But I was wrong, the new machine is faster.
I did a comparison converting the same 1080p video for play on my iPhone which is 1/4 of that resolution.
2009 Mac Pro = 14:05 minutes
2013 iMac = 13:05 minutes
So the new iMac clearly beat out the old beast by about 8%. That’s a very pleasant surprise.
Here’s the specs that matter in making this computer expensive and a worthy successor to my old pro-grade computer:
3 TB fusion drive
32 Gig RAM
27″ monitor (all in one design)
That’s it really. It will drive two additional external monitors which I find essential. I might do some additional articles on why you would or would not want to spend upwards of 3K USD on a desktop computer. Spoiler alert: if you can do what you want and are happy with what you have then you don’t need it, and the vast majority of users don’t need any more than what a smartphone or tablet provides. Your mileage may vary.
