Appleinsider posted a small update today which claims that second generation PowerMac G5s would make an appearance by March 2004. The new machines are reported to have advanced features including 533 DDR II RAM support and up to 1.5GHz bus as well as the incorporation of 90nm G5s and "Power Tune" technology.
As previously reported, IBM will be presenting 90nm PowerPC 970 technology at the ISSCC in Feb 2004. First reference to "PowerTune" was seen in the advance program (PDF) where it is briefly described under "PowerTune: Advanced Frequency and Power Scaling on 64b PowerPC Microprocessor" (Page 59)
PowerTune is a power-management technique for a multi-gigahertz superscalar 64b PowerPC processor in a 90nm technology. This paper discusses the challenges and implementation of a dynamically controlled clock frequency with noise suppression as well as a synchronization circuit for a multi-processor system.
It's not completely clear how these 90nm G5 machines would fit with Appleinsider's previous claim that PowerMacs would see revisions in January 2004.
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 announced the original Mac Pro 20 years ago today, with the anniversary landing five months after the company discontinued the machine for good.
On August 7, 2006, Apple unveiled the first Mac Pro, powered by two dual-core 64-bit Xeon processors that Apple said made it up to twice as fast as the Power Mac G5 it replaced. It was the last Mac to complete Apple's transition from PowerPC...
