iPhone 17 (Late 2025)

The iPhone 17 features some upgrades over the iPhone 16 in some key areas: a more power efficient A19 chip, a better screen, and stronger glass to match. While it looks very similar on the outside to the previous generation, you’ll notice right away when you start using it, how fluid the screen is. That’s […]

iPhone 17 Pro and Pro Max (Late 2025)

The choice of Aluminum marks a second major shift in the type of materials used in the frame of flagship iPhone models. Up until the 14 Pro, iPhones used Stainless Steel, then transitioned to Titanium with the iPhone 15. With the iPhone 17 Pro and Pro Max, the choice for an Aluminum alloy was made […]

iPhone Air (Late 2025)

The iPhone Air is the thinnest iPhone to-date, measuring in at 5.6 millimeters thick. The device is more “form over function”, highlighting aesthetics over additional battery, cameras, and thermals. It contains a 3149 MAh Lithium-Ion battery which is somewhere between “small and medium” sized this day in age. Having an A19 Pro chip means it […]

Broadcom BCM5780 Mid-and-South Bridges (PCIe Power Mac G5)

When the Dual-Core PowerPC 970MP third-generation G5 CPUs came out in Mid-2005, Apple had to start using a brand new Mid Bridge chip for the Macs along with it. Since the AMD 8131 only had PCI-X bridges and no PCIe bus, they couldn’t keep the old chip, replacing it with the BCM5780. (Above: Block diagram […]

AMD-8131 PCI-X Midbridge Chip (2003-05 PCI-X Power Mac G5 only)

Have you ever wondered why there’s an AMD chip on the back of your Power Mac G5’s logic board, or what it’s even doing there? For higher end Mid-2003 thru Early 2005 Power Mac G5s, that’s the PCI-X “Mid Bridge” chip. This is what handles all your expansion cards! Although, it doesn’t appear in Late-2005 […]

IBM CPC945 Northbridge chip tech specs (Late 2005 Macs)

The IBM CPC945 is a redesigned Northbridge chip mostly for the Dual-Core PowerPC 970MP CPU. It has technical upgrades over the IBM CPC925, including a faster HyperTransport Bus. It’s also capable of talking to the PowerPC 970fx second-generation G5 chip, which means it may be found in other Late 2005 Macs on the logic board. […]
