In the aftermath of the launch of Mac OS X 10.5 Leopard, which has already sold more than two million copies, Apple has beefed up its laptops with new processors and chipsets from Intel's "Santa Rosa" platform. As MacRumors says, the change was done quietly with no PR announcement from Apple, and MacBooks are still offered at the same $1,099, $1,299, and $1,499 price points.
However, MacBooks now ship with 2GHz or 2.2GHz Core 2 Duo processors with 800MHz front-side bus speeds, compared to 2GHz or 2.16GHz models with 667MHz FSBs before. Apple has replaced the machines' Intel GMA 950 integrated graphics with GMA X3100 graphics, and the highest capacity hard drive is now a 250GB 5400RPM model rather than the old 200GB 4200RPM offering.
Apple now offers a 2.6GHz Core 2 Duo processor and a 250GB hard drive as options for MacBook Pros, as well. Like the updated MacBooks, the new MacBook Pros are available right now from the Apple Store.
