If I were to buy a PB today (or wait a few days to see if there are updates ) will the 64MB graphics card be adequate for all the cool new Core Image stuff in Tiger?
Apple used to have a list of cards in their website that were 'good' for CoreImage and the current PB's card was one of them. Now that list is gone, and there is no indication as to which ones will be and which ones won't.
I would think it would be fine, but I am not sure.
Thanks. Does this hold true for the NVIDIA GeForce FX
Go5200 in the 12" model?
EDIT: YES, it does hold true for NVIDIA GeForce FX Go5200.
The performance gains and features supported by Core Image ultimately depend on the graphics card. Graphics cards capable of pixel-level programming deliver the best performance. But Core Image automatically scales as appropriate for systems with older graphics cards, for compatibility with any Tiger-compatible Mac.
Supported graphics cards:
ATI Radeon 9800 XT
ATI Radeon 9800 Pro
ATI Radeon 9700 Pro
ATI Radeon 9600 XT
ATI Radeon 9600 Pro
ATI Mobility Radeon 9700
ATI Mobility Radeon 9600
NVIDIA GeForceFX Go 5200
NVIDIA GeForceFX 5200 Ultra
Anyway, even with not supported video cards, you would still be able to enjoy Core Image experience.
"computers without a programmable GPU, Core Image dynamically optimizes for the CPU, automatically tuning for Velocity Engine and multiple processors as appropriate."

The new PowerBooks should have 128MB GPUs in the high-end 15" and 17" versions
Do you think it will make a noticable difference with 128MB on the 15" 1280x854 screen?
After all it's another $100...
I ordered my PB with 128MB GPU - 30" support and also I'm going to run motion. If you're going to use any graphics programs or anything powerful then get it (if your not get an iBook!!!)
From the list it looks like Core Image needs at least some sort of programmable vertex sharder support (equivalent of MS DirectX 9).
This is also consistent with the fact that Radeon 9200 is absent from the list since the processor is actually a mildly crippled version of the one that appears on 8500 and does not have programmable vertex shader engine.
In the case of 9200, the Core Image will probably dump the shader vector calculus onto the CPU. I'm not an expert on the G5 architecture, but G5/G4 probably has vector calculus instruction coded in hardware (like Intel's SSE/SSE2/SSE3) and the hit on the CPU performance will be quite minimal unless lost of complex visual effects are rendered at the same time. For casual business user it will do just fine.

Correct. Apple says that in computers without a programmable GPU, Core Image will try to use Altivec, the vector unit that every G4 and G5 has. Core Image is also multi-processor optimized (see previous link).

That's good to know but unfortunately I think my budget will only stretch to a 12"

well hopefully they'll offer it as an option in the 12" and the 15" combo?!

It will. Max it out and you'll be thankful when Tiger arrives.
