Sadly the tech specs still only list the 9400M as supporting H.264 acceleration whereas for OpenCL they have a decent list. Hopefully Apple will see fit to give H.264 acceleration to all nVidia 8000, 9000, GT100, and GT200 series GPUs since they all basically have the same PureVideo decoder inside. ATI GPUs since the HD2000 series have also supported full hardware H.264 decode and even the ATI X1000 series and nVidia 7000 series have partial H.264 acceleration, if Apple would choose to write the drivers for it.

I wonder if Apple will provide an API for third-party developers to enable hardware accelerated plugins for things like MPEG4 and VC-1 for Divx and WMV. They aren't as critical since they aren't as CPU intensive, but it'd still be nice to have.
We're still decoding DVD's via brute force on the CPU. Doing it using hardware video acceleration? :rolleyes:

What is this? OS 9?
 
From what I understand it does run in 64bit mode.


okay thanks It just hasn't been made clear what has and what hasn't be cause the whole 64bit thing helped me talk my dad into getting me a macbook. The opencl stuff and grand central helped too. I just told him that it would all help to make my computer faster and stay relevant longer and he finally agreed.
 
W7 has Direct Compute in DX11 which is like OpenCL. The applications can start taking advantage of GPUs using DX11 and it'll be just as fast as SL's OpenCL, they are basically the same thing. It'll be even faster on Windows since Windows support the latest and greatest of GPUs with greater numbers of processors.
I'm no expert, but my understanding is that Compute Shaders in DX11 and OpenCL are not in direct competition. I believe Compute Shaders are still implemented as part of the DirectX pipeline and so are more graphically focused in usage. Such as games, video encoding, visualization, etc. OpenCL however is supposed to be a more pure number crunching API that can be optionally combined with OpenGL 3.x for visualization.

Interestingly, from what I've read (granted forum posts only), Snow Leopard doesn't seem to include full OpenGL 3.0 support even though both nVidia and ATI have long released OpenGL 3.0 drivers for Windows and Linux for their DX10 GPUs. This would seem to inconvenience some of OpenCL's potential usage.
 
All of it being made by you voicing on matters you know nothing about.

Snow Leopard is 32/64bit - the 32bit version uses PAE which provides 36bit addressing.

The issue for those of us still in 32bit mode has to do with the fact that not all the drivers are 64bit - My MacBook has a 64bit processor (Santa Rosa) but due to Apple being too bloody lazy to create a 64bit X3100 driver, I am stuck in 32bit mode.

I swear I'm tempted to move to Windows 7 due to Apples pathetic support of computers that are less than a year old, 64bit capable but they decide to cripple the experience for their customers.

Thanks for your kindness in pointing that out, appreciated. Hope you are happy with W7.:)
 
OpenCL apps will start appearing quickly. Its C-Like and integrates like OpenGL in coding. Not too hard from example code aswell.

OpenCL will most likely become the standard, like OpenGL. Microsoft will just do what they do with Direct X, push it in games.

Yes, but GCD/OpenCL code won't run on Leopard or previous OS. The question is how much resources are developers willing to allocate for OpenCL/GCD if the majority of in the install base isn't on Snow Leopard yet. Majority of developers are not going to code for a new OS until there is a widespread install base and that'll take a while.

MS is intentionally developing Compute Shaders to compete against OpenCL, they both do the same thing. Compute Shaders isn't for graphics only, it can do pure math work just like OpenCL. They are very similar in that nature.

Will my 2008 iMac (8,1) have 64bit kernel? I know it isn't compatible with OpenCL...even though I bought it less than a year ago.
 

Interesting...

I was hoping it was 9 simply because it would be weird for Apple to keep 8 on the 10.6 GM that might not release until the end of Sept when 9 might possibly be released with the iPod refresh in early Sept.

Ok? Except that Snow Leopard is finished.

iTunes 9 probably isn't yet.

Does 64 bit work on the MacBook 4,1?
 
I don't get it, how they are gonna check if I do have the Leopard or not? So did by my MB from the second hands almost new, just used a few times and Tiger on it. Does it mean I still will have to pay full price for Snow Leopard?
 
lol its kinda annoying people asking the same question "oh i want to be able to do an erase & install & i want a clean install". of course you will, its going to work like it has done for every OS X upgrade disk

stages

1. Pop in the install DVD & press C
2. wait for it to load up
3. Once loaded the disk will scan for a Leopard install, once it has found it on the hard disk you will be able to continue
4. After that you can either chose an upgrade, archive or erase and install,

not hard really is it LOL
 
Some of you have no idea what you're talking about.

PAE is not used.

To support large amounts of RAM, OS X actually uses the 32 bit sub-mode of the 64 bit mode on an Intel processor.
