Snow Leopard in action looks a lot like OS X Leopard, but its significantly faster, according to Apple.  (Source: Apple)

Apple is ready to spread OS X 10.6 to the masses

Apple's new operating system, OS X 10.6 "Snow Leopard", will beat the company's own launch target of September – an official launch date of August 28 was just announced.  The new OS is priced at $29 per license for OS X Leopard users (with additional discounts for bulk license users).  Apple notes, "Snow Leopard builds on a decade of OS X innovation and success with hundreds of refinements, new core technologies and out of the box support for Microsoft Exchange."

Bertrand Serlet, Apple’s senior vice president of Software Engineering, describes, "Snow Leopard builds on our most successful operating system ever and we’re happy to get it to users earlier than expected.  For just $29, Leopard users get a smooth upgrade to the world’s most advanced operating system and the only system with built in Exchange support."

The new OS is set to go head-to-head with Microsoft's Windows 7 and delivers many major improvements for Mac users.

Over 90 percent of the 1,000 core programs in OS X had their performance tuned and improved, according to Apple.  Many -- namely, Finder, Mail, iCal, iChat, and Safari -- were moved from 32-bit into a 64-bit world, which boosts memory performance, among other things.  Apple says that its Finder is "more responsive", its Mail client is twice as fast, and Time Machine is 80 percent faster at its initial backup.

Apple includes the new QuickTime X and Safari 4 with the OS.  Apple says that the new version of Safari is more resistant to plug-in crashes and 50 percent faster at general web browsing (Safari recently received the accolade of being listed by Futuremark as tied with Google's Chrome as the fastest browser).

The size of the installation has also been cut in half freeing 7 GB. 

Apple is pushing a couple of new technologies with Snow Leopard.  The first is its Grand Central Dispatch (GCD) a technology designed to optimize multi-core usage.  Another new tech is OpenCL, a C-based open standard, which looks to provide heterogenous processing on both GPUs and CPUs.

Ironically, one of Apple's biggest selling point with the new OS comes from competitor Microsoft.  Apple explains, "Snow Leopard is the only desktop operating system with built in support for Microsoft Exchange Server 2007, and it allows you to use Mac OS X Mail, Address Book and iCal to send and receive email, create and respond to meeting invitations, and search and manage contacts with global address lists. Exchange information works seamlessly within Snow Leopard so users can also take advantage of OS X only features such as fast Spotlight searches and Quick Look previews."

Unlimited licenses of Snow Leopard are available for $499, half the price of an unlimited pack for Leopard.  The new OS will start shipping this Friday to customers that pre-order.  Amazon.com has already been holding an unofficial pre-order for the last couple weeks and saw Snow Leopard jump to the top of its software sales charts.

Snow Leopard Server will launch on August 28, as well, alongside the new consumer OS.  The Server edition comes with Podcast Producer 2 and Mobile Access Server and costs $499 for an unlimited license.

Obviously Pirks, Floating Point performance, you know, half point of having a GPU in the first place is totally irrelevent.

Sad part is you actually have people in here believe what you are saying. Gaming performance is a direct gauge of floating point performance, thus my 'stupid irrelevant' reference to Crysis turns out to be very much so relevant.

The 9400m is a 16 core GPU, and while that maybe fine in the mobile world, it is dwarfed by the performance of desktop cards.

Here is just an example of the difference: (go find any benchmark all will be pretty much the same)

Here is just an example of the difference: (go find any benchmark all will be pretty much the same)

9400m OpenCL preview
OpenCL float performance- 18074 / 15892 kPixel/s

9600GT (64 cores, not a new top of the line GPU)
OpenCL float performance- 86.14 / 10.82 MPixel/s

Notice how the 9400 is measured in kila-pixels and the 9600gt is measured in Mega Pixels , the difference is night and day. (somewhere in the magnitude of 6x)

I thought you had outgrown your shenanigans, I guess I was wrong..

P.S The only reason I used crysis as an example is because I assumed not that many people here realize what Open CL actually does. Calculations that run on the GPU will be taking advantage of its floating point performance (FLOPS), and the simplest way to show this kind of performance is simple gaming benchmarks. You can know right off the bat how useful a GPU will be for OpenCL just by looking at something as simple as this. The fact remains a 9400m will see little to no benefit, this is even evident on your beloved Apple forums where there are multiple threads dedicated to the topic.

Taking this even further, OSX 10.5 already performs load balancing between the CPU and GPU for certain calculations with Open GL. As such the benefit of OpenCL is even less, as a similar system is already implemented.

I think he was just talking about price wise. And I think having to spend $1800 Just to get up to the GT120 is much of an improvement. You really do almost have to get a Mac Pro to get something better than the 9400M. Only ones available on non-Mac Pros are the 9400M, 9600M, the $1800 iMac with a GT120 and the $2200 iMac with a GT130. That's it. I'm not sure how much a better GPU will help, but having to spend $1800 just so you get something better than a mobile GPU is quite sad.

Just when I thought that liver donation got the best of you, you come back from the dead.

I even had your funeral song prepared....

Not even an insult from you? I'm quite shocked that you have absolutely nothing to say against my facts.

What facts? About iMacs that have pretty powerful GPUs like Radeon 4850? Sure thing buddy, this is exactly why I called the omni's lies about Mac Pro. Any more questions on that?

For $2000+ and for a $200 upgrade on a card that costs about half that brand new and at full price? I'm sorry, but it may seriously just as well be a Mac Pro. I've been saying the whole time that it's more about the price you can get them at and not just about what computers you can actually get it on.

All nice.

But quite irrelevant with regards running games on OpenCL... 'cos no-one is going to do that.

Realistically, right now the bottleneck is the GPU, so moving more non-graphical work to the GPU is not the way to optimum frame rates.

While I agree with your overall statement about desktop vs mobile cards the example you used doesn't really show it..

9600GT (64 cores, not a new top of the line GPU)

Just FYI ...

15896k > 10.82M

The other number is a different story but you might want to highlight what's actually being measured.
