Roadmap 2010: Mac Pro

Although supplies of some components Apple wants to use in the 2010 Mac Pro may cause further delays that cannot yet be precisely anticipated even by senior executives at Infinite Loop itself, a considerable leap forward for Cupertino’s high-end workstation is widely anticipated in the next few weeks.

As is typical among seasoned rumor-mongers, we are hesitant to try to predict in anything but general terms when to expect this update; Apple has extremely high standards for predictable supplies of components (brought about by snafus like the major delay in availability of PowerPC G4 processors when they were first introduced), and is quite willing to push back its own planned announcement dates if there is the slightest question of availability or quality-control problems.

Impressive Mac OS X 10.6 “Snow Leopard” build 10A335 seeded

Despite being a mere 21 builds apart from the previous seed, 10A314, released earlier this month….the latest Snow Leopard seed (simultaneously released in both Standard and Server versions) has definitely taken a big step forward in many areas.

Several elements of the full internal Mac OS X 10.6 code tree, such as the “Marble” interface revamp and overhauled Finder as well as the entire PowerPC version of the operating system, continue to be withheld from the developer builds — but even absent those more visible features, Snow Leopard is truly beginning to shine and show full potential with the advent of 10A335.

Performance is a notable area of big improvement since build 314 was released at the beginning of April; already stunningly fast, sources confirm that 335 removes a significant amount of debug code which always bogs down developmental versions of OS X as compared to their final-release counterparts.

Next-gen iDevice picture coming together

Already, the grapevine has sussed out a tremendous number of details about the four (planned, if not necessarily all shipped at the same time this summer) new iDevices:

*A huge order of NAND Flash memory storage chips, the same (but of higher density & performance — even lower power draw, in most cases) used in current iDevices for data storage, has been placed by Apple with several suppliers including Samsung. That in and of itself isn’t news….Apple has become a key buyer of these chips. What’s news is that the order is so incredibly massive that it will strain the market and might even make it challenging for the entire market for this class of Flash memory to become “constrained.” It could even have a significant effect on the market pricing of these chips going forward.

Will Mac OS X 10.6 “Snow Leopard” really support PowerPC?!

Ever since we posted our first ‘sneak peek’ at Mac OS X 10.6 “Snow Leopard” two weeks ago, one of the most frequent questions and lingering doubts amongst readers surrounds the issue of support for PowerPC (G4/G5) based Macs. Will it really be present in the final version? Tonight we took a moment to answer that question as best we could for a reader who asked about it in the comments section of the aforementioned article.

“Mizhou” wrote: “A friend of mine just tried to install on a 1.8 GHz G5, and the installer just says that it is an unsupported architecture.”

Quoted from the response by our founder, Ryan C. Meader (@dalaixerces on Twitter):

Internal builds we’ve worked with have (and continue to) support PowerPC but there are increasing signs that the final version may not. Read more

Will my GPU be fully supported by Snow Leopard’s OpenCL?

According to reliable sources, if you own an Intel Mac other than the Mini or an original Macbook — either of which shipped with Intel’s GMA950 integrated GPU — then you are already good to go for support of the full range of OpenCL acceleration features.

If you have a Mac with the Intel GMA950, then you will get most of the benefits of OpenCL though the performance level of those functions will be significantly lessened due to the lack of dedicated graphics RAM and absence of support for many programmable GPU features that exist in other chips/cards going back to the ATi X1000 series.

To get that full support, GPUs as “old” as the ATi X1600, X1800 and X1900 (the latter of which was available for PowerMac G5s with PCI Express slots, based on the PowerPC 970MP dual-core processor while the former shipped in early Intel iMacs and its X1600M cousins in Macbook Pros) will do the job….but certain nVIDIA cards from the GeForce 7000 series, which shipped in iMacs and PowerMacs during the G5 era, most likely will not.
