Here are the technical innovations in the new G4 (updated)

Those who expected a revolution from the new G4s were not satisfied. But if those who were expecting the improbable debut of the G5 are disappointed by the update, it would be bad to underestimate the architectural changes that Apple's machines introduce.

The most relevant, as can be seen from the technical specifications published just a little while ago, the use of the scheme seen on the XServe which increases, according to what Apple learns, the data trhoughput. A centralized system controller coordinates and manages the transfer of instructions from the PCI bus, memory, graphic bus and I / 0 of the machine.

Apple also presents the new 333MHz DDR SDRAM PC2700 memory (on the 1 GHz model DDR SDRAM PC2100 at 266MHz) which should provide a significant contribution to the increase in performance.

Of course, also the adoption of the 1.42 Ghz processor on which apple does not provide explanations and details but which should be the now known MPC 7455 (not the rumored and not yet presented MPC 7457)

There are also relative but still significant news, such as the debut of the FireWire 800 and the internal predisposition for Bluetooth.

Coming to the specifications of each machine one of the most striking data, because unexpected, the return of the monoprocessor. This is the 1 GHz version that takes the place of dual 867 MHz. Apart from this aspect (certainly not irrelevant) the machine remains in fact the same with a combined DVD and CD-RW unit (reads 12x DVDs, writes CDs). -R at 32x speed, writes CD-RWs at 10x reads CDs at 32x), same video card and same Ram equipment as well as the same HD (60 GB). In addition, the predisposition for Bluetooth and for Airport Extreme and FireWire 800. As mentioned, instead, the price changes from 2278 euros to 1798 euros. The 1 GHz model stands out from the others in the range for the motherboard with 133 MHz processor bus.

On this product, Apple has obviously reached some compromises, sacrificing the equipment for a very attractive price.

The 1.25 GHz version, today in fact a mid-level, the same (always except for the Bluetooth and FireWire 800 predisposition and the combo instead of the Superdrive). Here we always find the 167 MHz system bus and a Radeon 9000 Pro (instead of the GeForce 4MX of the 1 GHz model) and 256 MB of Ram. The price 2518 Euros against the price of the previous mid level which was 3238 Euros but with 1 GHz processor. Compared to 1.25 GHz the second level cache drops from 2 to 1 MB and the Ram goes from 512 to 256 MB

The "excellent" model sees the debut of the 1.42 GHz processor. The machine has 512 MB of Ram and a new DVD burner updated to 4x (read DVD at 8x, write CD-R at 16x writes CD-RW at 8x, reads 32x CDs). The cost of 3358 euros against 4318 of the previous model which was a 1.25 GHz.

Finally, the model "the maximum" (two Ultra ATA 120 GB and 2 GB of Ram, Nvidia Titanium graphics card) costs 6334 euros, always with the equipment of the new 4x Superdrive.

Note that, according to some Macity sources, the interior of the new PowerMac has been redesigned so as to significantly reduce the noise of the previous models, one of the most annoying defects of the Pro hardware in recent months.

The new machines, we remind you, are only able to boot from Mac OS X. For those who need to still use Mac OS 9, two models remain available, respectively from 3118 euros (double 1.25 GHz; 512 MB of Ram) and from 4386 euros (similar to the previous one but with Nvidia Ti graphics card instead of Radeon 9000). Both machines have a combined DVD + CD-RW burner. A different choice from the one implemented in the USA where Mac OS 9 machines have superdrive. Note that 1.25 GHz for Classic have more than those for Mac OS X 2 MB of third level cache (instead of 1 MB) and 512 MB of Ram. HD is also larger than 120 MB instead of 80 MB.
