Mac for Jitter // external graphic card needed??

Hi to everyone,

I can buy a new computer “dedicated only” for Jitter!!!

Time ago i tried to do audiovideo in real-time with jitter on a single mac book pro1,1
processor 2 GHz
RAM 2GB
ATI Radeon X1600.

Using IshowU HD for recording my desktop in real-time.

Happened a great disaster :) …… obviously. // frame drops etc etc
All were slow, and I couldn’t do a lot of thing.

And i love the audiovideo!!
____________________________________________________________

I need a computer for analyze the audio input data and display them using the OpenGL objects.

I’m planning to take a MacBook Pro

PROCESSOR: 2.7GHz quad-core Intel Core i7 processor (Turbo Boost up to 3.7GHz) with 6MB shared L3 cache

MEMORY: 16GB of 1600MHz DDR3L onboard memory

GRAPHICS AND VIDEO CARD: Intel HD Graphics 4000

NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching

Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors
Thunderbolt digital video output

Native Mini DisplayPort output

β€’β€’β€’β€’β€’β€’β€’β€’β€’……………..β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’……………..β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’β€’……………..

Will Be enough or is better enhance the video card up to 2GB?

Or is better to have an external dedicated graphics card ?

I have heard whisper about these:

I know that some artists use external graphics card.

What should i do?

Thanks
greetings

If you wanna get serious with graphics and have the cash: go for 2GB. It will give you more headroom when working with large textures and multiple HD screens. Though 1GB will likely work for the majority of things you’d wanna do.

AFAIK external gfx cards aren’t very useful at the moment. This might change when very high speed Thunderbolt-PCIe adapters suitable for gfx cards emerge (with 8/16 PCIe memory lanes). You wanna make sure that whatever you pick has good openGL support.

Do you really need a laptop? Desktops are way more flexible. You can swap out the card for a better one if you bump into its limits at some point.

Do you plan to add a SSD ? or is it standard in this config ?

Hi Stephane, in this configuration is standard, they told me.

512GB or 768GB of flash storage // flash means SSD , they told me that is a synonymous.

I think that with two laptops is simple, just a bag for notebooks, and you can go where you want.

DTR : if you have a tour in The Netherlands, for example …… How do you organize with a desktop computer?

////////////////////////////////////////////////////////////////////////////////////
perhaps also take a 13-inch MacBook Pro not retina

PROCESSOR: with 2.9GHz dual-core
Intel Core i7 processor (Turbo Boost up to 3.6GHz) with 4MB L3 cache

RAM: 8GB of 1600MHz DDR3 memory

GRAPHICS CARD : Intel HD Graphics 4000 (all 13- and 15-inch models)
NVIDIA GeForce GT 650M with 512MB of GDDR5 memory and automatic graphics switching (2.3GHz 15-inch model). The optional 2.6GHz and 2.7GHz 15-inch models come with NVIDIA GeForce GT 650M with 1GB GDDR5 memory.
Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors

and an external dedicated graphics card could be a good solution?

Perhaps a good Desktop may be the right solution…

Another solution :
Soon will come a new Mac Pro “desktop” model the design is ultra strange http://www.apple.com/mac

-If i had the skills i would consider as a desktop a hackintosh ;), anyway!

Not to say that I’m confused, ––––– i would say that I do not exclude too many possibilities !

> DTR : if you have a tour in The Netherlands, for example …… How do you organize with a desktop computer?

I drive or have my gear transported. I have way more stuff than the computer to take anyway (beamers, stands, etc).

> Perhaps a good Desktop may be the right solution…

Ah yes, when I said desktop I meant hackintosh or windows.

Thanks for your help!

I have to correct , it is impossible to have 2GB for the graphics card on laptops, i have been given wrong information.

impossible on *mac* laptops ;) http://www.alienware.com/Landings/laptops.aspx

i would like to second the idea that a desktop computer is more suitable for “serious” video work.
at least this is true for apple hardware …

meh, i can do plenty on a macbook air with an SSD drive.

depends on what ‘s understood by ‘plenty’ hΓ© ;)
and that SSD is not going to improve openGL rendering in any way, is it?
