HDX vs HD2 power now and come 64 bit
If one HDX card is 5(?) times as powerful as a PCI-e accell card, what would be the comparison between a one card HDX system and my HD2? 2 to 2.5 times more power?
But if 11 goes 64 bit, doesn't that mean it has to do more calculations thus reducing that difference to.... what? I don't want to upgrade and come to the conclusion I need another card to get comparable performance in the future. |

No, it is the other way around. A 32bit system can only process data in 32bit long strings. A 64bit system can process double the amount of data of a 32bit system in the same time. I am not sure how AVID are calculating the speed of those HDx cards. If they are operating at 32bit internally on 64bit processors then we may very well see a performance increase come protools 11. |

Re: HDX vs HD2 power now and come 64 bit
Another question (if we are looking to the future) would be; how will this compare to the next generation of Native processing? Intel is not standing still either.

Pt HDX 1 is more powerful than a hd 3 system that says a lot already. Some say it's even more powerful than hd 4 and 5. The faster the host will be the faster the HDX card will be, to a limit of course. |

Re: HDX vs HD2 power now and come 64 bit
Generally, 64 bit is the same or a bit more efficient than the same app in 32 bit. Before other audio apps released 64 bit versions, some people mistakenly assumed things like performance getting cut in half but that wasn't the case at all. It's not 64 bit audio we're talking about, it's the code and the CPU - a better comparison is like a road getting upgraded from 4 lanes to 8 lanes, it lets it move the data around faster.

In the simplest terms, a 64-bit application runs almost the same as a 32-bit application, except for the amount of memory it can use. The main reason for wanting a 64-bit Pro Tools application is for using more memory, such as happens with really big virtual instrument plug-ins, or in rare cases, with giant post-production sessions with hundreds of tracks and hours of audio. Running as a 64 bit process doesn't usually change the performance of the application. It's perhaps confusing because we use "32 bit" and "64 bit" to refer to different things. A 32-bit application is independent from using 32-bit audio. Pro Tools uses 32 bit audio, and will continue to do so once a 64 bit version of the application is released. Hopefully that helps clarify it.
