Final Cut 10.1 dual graphics on 5.1

The only thing I have ever seen from Apple is that there is dual Graphics card support for the "new Mac Pro".

For example.

So I am doubtful.

I have been wondering this myself. I am about to upgrade cards, and if it will support the dual gpu I will get two 5770s... if not, I'm going with the 5870 unless someone would suggest somemthing better that is not out of budget.

From what I have learned it supports dual cards. There is no specifics about which cards.

i've tried 2 5770, works fine.

1 5770: 1 track 4K 25p playback better quality no frame drop

1 track 4k 50p playback better quality frame drop

2 5770: 1 track 4K 50p playback better quality no frame drop (no a/v output)

1 track 4k 25p playback better quality frame drop (a/v output 4k 25p by aja kona 3g)

i've tried 2 k5000, 2 cards don't make sense.

1 k5000 render time=2 k5000 render time

Yes; I've been reading the BruceX thread updates and it seems that the common wisdom (which I was sharing) is wrong. In this case, wrong is good.

This is excellent news. I have a 3,1. This is great news. May I ask what is the BruceX thread?

Sorry. I understand now! Missed that link

for xavc 50p，the fcpx use mainly cpu.

this is unlike prores422，

xavc50p can be 2 tracks video and 4 tracks text realtime with 1 5770 card

at better performance option.

in fact you will see little image quality loss

when choose this option.

this also prove decoding xavc uses cpu!

the brucex's test is not overall.

that test is almost use gpu,cause the project

is using fcpx generate text clouds etc.

however, if you render a dissolve of xavc clips,

1 5770 takes only 1/28 more time than 2 5770

here is the list i've done:

encoding 4k 50p xavc to prores 32s clip

1 5770 39s 2 5770 29s 1 k5000 50+s(i can't remember)

render 10s dissolve 4k xavc 50p

1 5770 29s. 2 5770 28s. 1k5000 35s

brucex test output prores

1 5770 64s. 2 5770 38s. 1k5000 about65s(not remember)

render 10s 4k xavc 50p gauss blur

2 5770 almost= 1 k5000

realtime play 4k 50p xavc

2 video tracks both primary colorgade

with4 tracsk text(with simple animated color block behind the text)

1 5770= 2 5770= 1 k5000

all can output 3g sdi 1080p50 to monitor

image quality: better performance almost= better quality

realtime playback 4kprores50p at high quality:

1 5770 drop frame

2 5770 dont drop

1 k5000 dont drop

but if ouput to sony monitor all drop frame

image quality:better performance << better quality
