Apple updates iMac, Mini today with nVIDIA chipsets instead of Intel

In a move that surprised even some of our sources and was in several key ways quite (but not entirely) contrary to our published projections as to the iMac’s specs, Apple announced new iMacs and Mac Minis today.

Although we are quite confident that Core i7 (“Nehalem” and “Gainestown” for desktop and Xeon products respectively) will indeed make its way into the Mac platform over the rest of the year, clearly the issues we’ve previously reported with Intel’s chipsets and the outstanding issues with some of the prototypes we’ve had the chance to examine (bugs, largely — though supply and timing were also reportedly issues; we had some internal debates over whether March 24th was really a remotely realistic announcement date, no less ship date) convinced the company’s decision makers to go with a Core 2 Duo based lineup using basically identical processors to previous models….merely adding more powerful memory, graphics, and nVIDIA chipsets.

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.
