AnandTech took a Mac Pro, which comes with two Dual-Core Xeon (Woodcrest) processors and replaced them with samples of two Quad-Core Xeon (Clovertown) processors.
We grabbed a pair of 2.4GHz Clovertown samples and tossed them in the system, and to our pleasure, they worked just fine. Our samples used a 1066MHz FSB, although we're expecting the final chip to use a 1333MHz FSB, but the most important part of the test is that all 8 cores were detected and functional.
The Mac Pro appeared to run fine with the Quad-Core processors, effectively giving them a 8-Core machine. While they are unable to give performance numbers due to non-disclosure agreements, the machine was reportedly stable. It also gives hope for current Mac Pro owners that they will be able to later upgrade the processors on their machine in the future. Clovertown Quad-core processors are expected to be available in late 2006.
Apple once developed "M2 Extreme" and "M3 Extreme" chips for the Mac Pro, but it decided not to release them, according to Bloomberg's Mark Gurman. He first reported on this topic in 2022, and he touched on it again in his Power On newsletter today.
"Extreme" chips would have had twice as many CPU and GPU cores as Apple's "Ultra" chips.
"The idea was to offer twice as many graphics and...
Apple developed two Mac Pro models in recent years that never made it to market, according to Bloomberg's Mark Gurman.
In his latest "Power On" newsletter, Gurman revealed that Apple internally developed two unreleased Mac Pro projects codenamed J170 and J190 before ultimately discontinuing the machine altogether.
As for new Mac Pro hardware, there were two additional models developed by...

Apple is developing an all-new operating system that is essentially a mix of tvOS, watchOS, and iOS, according to Bloomberg's Mark Gurman.
In a report this week, he said the operating system will feature a grid of icons, widgets, and apps, along with customizable clock faces.
The new software platform is intended for Apple's long-rumored smart home hub. With built-in facial recognition,...
