Shared memory is not the highest performance alternative in any
operating system. When the video memory is part of system memory then
the processor the video controller fight for memory bandwidth. This
slows both down.
So, the question is: what to choose, integrated intel solution or
ati/nvidia one (in this case, nvidia is preferred, because of driver
quality).
Choose a good controller with a bit of dedicated video memory. For
purely audio apps you don't need all that much, but if you're going to
run video apps or do multimedia stuff then you'll want more.
It's hard to find light laptop with dedicated controller at a reasonable
price :)
Is it possible to do 8in/8out and 64-sample buffers with RME Multiface
CardBus on a laptop with shared video memory?
And the only one(and expensive one) I found is with nvidia controller
(Sony Vaio VGN-S480). Not sure about nv TurboCache - is it a shared
memory solution?
Seems i want too much to be in one unit.
