CUDA performance is still greater than the Open CL performance. If you have the choice then get the Nvidia and Alex is right on the 760GTX.

Hehe I didn’t know Dell had a all SSD policy if you buy 1. That is a new 1 I haven’t heard before even from a Dell sales person 😉 I think I see why HP protects their Var’s so much sheesh.

The first factor on threading is the codec and what amount of threads it takes for the player to ideally decode the media. This means this is dynamic based on the media used and the player used for decoding. That would be very difficult to document. However I can give you a general rule that does cover the majority of codecs. The higher the compression level the less threads required to ideally decode. Instead you want GHz once you reach 8 to 12 threads. The Lower the compression level the greater threading that will ideally decode so GHz is not as important as long as it’s 2.6GHz or higher. Red however is a world by itself because the compression level can be high with the amount of frame data the codec is holding. So since Red has a higher compression ratio with also a high data rate then it takes as much of both as you can give it with Adobe.
The GPU acceleration with Premiere performance/load is decided first by the CPU’s since the CPU’s have to decode the data before the GPU’s can process it. This means the CPU’s drive/feed your GPU’s. If your CPU’s are slower in feeding the data then far more of the GPU processing capability sits idle. If there is not enough system ram to efficiently transit the amount of data ready for GPU processing down to and back from the GPU Ram/GPU then much of the GPU processing capability sits idle. That is why having the best GPU’s and the incorrect core system configuration is a bad idea.
AE performs far better with Multiprocessing on. I am really not sure why people would turn that off. However if you do AE will still thread out some or among all threads available with some media and others it wont. FX though are the primary limiting factor to AE threading. Some FX do not thread well which means those FX when used will limit your threading performance no matter what media or settings are used then. Adobe is not forthcoming with any information as to which effects thread and which don’t so you have to test and see to find out for yourself.

14K can get you a maxed out Dual Xeon E5 24 Core/ 48 Thread PC that is heavily configured and still upgradable in the future. No Way the new Mac Pro can compete with that unfortunately. I suggest you consider this.

Unless the codecs/FX limits you, AE and Premiere will thread out to the cores/threads available. 4K media especially Red really needs more threads so I suggest you re-think this.

BTW after testing some of James AE projects I have to retract earlier statements on Red Giant Plugins. They are threading great now with AE. In the past I stated they were not since evidently things have changed. Thank you and sorry Red Giant.

If you transfer over a network then the OSX file system doesn’t matter. If you transfer by removable drives then Mac Drive is the simplest solution for the PC.

Or the firmware was updated and they prevent backward compatibility to streamline support and backend process. Keep in mind with EFI in the mix they can prevent booting to any boot manager they want. That is why EFI is going to change things.
