An MHz model with a SuperDrive! It came with a new L3 cache, as did the mid-range MHz model. August of brought with it the final form of the Power Mac G4. Named "Mirror Drive Doors," this case was much closer to the QuickSilver than the QuickSilver had been to the Graphite, but the front panel was radically different, with its four new air intakes and media drive doors gaining a mirror-like finish:.

These machines quickly became known as the "Windtunnel G4" for the amount of fan noise. Apple eventually offered a replacement program for the power supply and fans, but the name stuck. With much faster components than previous G4s, the Mirror Drive Doors came with variable speed fans.
This was an attempt on Apple's part to keep the noise down, but the machine still gained a reputation for being too loud for some customers. A quick look at the back of the three case styles shows how much more air Apple was trying to move through the Mirror Drive Doors case:.
Above it were dual 1. The new connector came with much faster data rates than FireWire This was a big deal for video and graphics professionals working with large files. While offering so many new features, Apple was able to drop the price this time around.

The entry-level, dual 1. The high-end dual 1. The FW was meant to be the latest and greatest, and it delivered on that promise, but it wasn't the final Power Mac G4. That goes to a machine that, as Thomas Brand wrote on Pixels, was somewhat unusual: PowerPC G4.

Processor Upgrade: The Power Macintosh G4 Quicksilver models have the processor mounted on a custom pin daughtercard. System Bus Speed: This system has a k "on chip" level 2 cache running at processor speed and a 2 MB backside level 3 cache running on a bus one-fourth of the processor speed MHz. L1 Cache: RAM Type: RAM Speed: Apple also noted that this model has "full bit internal memory data paths". Standard RAM: Motherboard RAM: None RAM Slots: Video Card: The video card occupies a 4X AGP slot. Standard VRAM: Display Support: Single Display Resolution Support: Apple advertised that this system can support "up to by pixel resolution at 32 bits per pixel millions of colors ".
None 2nd Max. Standard Storage: Storage Speed: Storage Dimensions: Can officially support two 3.
Officially, drives larger than GB are not supported. However, third-parties have discovered that this system will natively support hard drives larger than GB, when running MacOS X Standard Optical: Standard Modem: Standard AirPort: USB Ports: USB 1. The MHz model was notable for not having a level three cache.
Quicksilver received criticism in MacWorld's review for removing the "eject" button and the manual eject pinhole, as well as the pass-through monitor power plug, and for the base specification of MB RAM as being insufficient for running Mac OS X.

This was the first Mac to reach 1 GHz. Again, the low end MHz model did not include any level three cache. All models were available in dual processor configurations running at MHz , 1 GHz or 1. A single processor 1.

The last real update to the Power Mac G4 line was on January 28, offering dual 1. Between that, its low price-tag, and the delayed availability of Power Mac G5s, it proved a strong seller for a relatively short time. Production stopped on June 27, and the remaining inventory was liquidated, ending the year legacy of Classic Mac OS support with its discontinuation. A limited range of serial numbers of this model was noted for a noisy fan, earning them the unofficial designation " Windtunnel G4" in some communities.
Power Macintosh G4 (AGP Graphics)
Noise complaints became such a problem that Apple later replaced the machine's power supply PSU and primary cooling fan with quieter versions, and initiated a voluntary do-it-yourself DIY replacement scheme for all previously sold machines. It is believed [7] that the reason for the problem is a bug in the CPU with handling cache coherency in dual cpu setups when switching the CPU to low power states.
In a low power state, each CPU would have only consumed about 5 Watts [9] or even less when switching to even lower power states , making for 10 Watts needing to be cooled. But when run in full power mode as to circumvent the cache problem , each CPU does consume about 50 Watts making for a total of Watts [10] —essentially the upper limit for which the cooling system was designed, making the fans run at full speed, even when the machine is mostly idle.
Soon after suggesting that hack to Apple, a new firmware was released, [15] disabling the API for switching between single and dual CPU modes. At least some MDD models also have a design flaw resulting in noise in the audio-out, picking up interference from the mouse, graphics card, hard drive and other hardware. According to Apple, this is a ground loop issue, and only occurs when used with professional balanced signal audio equipment, [17] however some audio experts contended it is due to shielding defects on the motherboard and affects all equipment.
