Well I believe the ram and the bus are the G5 capabilites. I heard they should have USB 2 and I guess FW2.
I read somewhere that the main thing (or one of them) keeping a lot of pc users from the mac is our slow memory and bus. So hopefully we'll get that fixed on the next revision.
your proposition seem to be realistic. Perhaps there will be only ATA 100, Apple is always late concerning the IDE controller, and very in advance concerning firewire or usb and even ethernet.
Even if the G5 will be not here i think there will a new G4 able to work with DDR ram. This a very good way to improve the performance.

anyone know if the actual connector will be the same for all these different speeds and just the cables themselves will be different? seems strange that you can go over cat5...

New Bus Topology/RapidIO Interconnect Architecture
32 & 64 bit (backwards compatible)
Symmetric Processing Capabilities
Part Number 85xx
What is RapidIO?? (www.rapidio.org)
A high performance low pin count packet switched system level interconnect architecture. Applications include interconnecting microprocessors, memory, and memory mapped I/O devices in networking equipment, storage subsystems, and general purpose computing platforms. This interconnect is intended primarily as an intra-system interface, allowing chip to chip and board to board communications at giga-byte per second performance levels.
A good guide to use is Motorola's first chip to include RapidIO, which is also a chip that falls in the 85xx numbering scheme. The MPC8540 is an integrated host processor with the following:
Dual Integrated IEEE 802.3 10/100/1G Ethernet
64-bit PCI-X controller up to 133MHz
333 MHz DDR memory controller
4 Channel DMA
Full duplex port connections at 128Gb/sconcurrent throughput and independent per port transaction queuing and flow control.
This looks very much like a nice little test bed for what will be on the G5.
As for the other stuff, I would guess:
USB2
FW2
ATA100-133 (tough call)
Definately DDR but what speed?
Will they skip to a double or quad pumped system bus?? Or does RapidIO eliminate the need for that??
My guess is you'll see a G5 in stores between Jan & Feb, I've got my money saved.
Nobody wants to comment on the MPC8540 and if it's a member of the G5 family??? Someone must have some opinions, I'm betting it is an early family member, look at what it has and what the G5 roadmap shows. Granted this is not a processor for desktop computing, but it's a good benchmark for the G5 if they are related.

I can't buy that. Like some PeeCee user is thinking, "Sure the OS is great and the video card kicks ass but man that memory bus is just too slow for my needs".

Ah, gee, yea, because the slow bus and memory bottleneck the speed slowing it down. I think that speed is one issue with PC users, I dunno, just a guess

Except for the geeks nobody cares or even knows about system bus speed. Bigger problems facing someone changing from using windoze to Mac OS are price and compatibility with others in their computer neighborhood. Use of open standards for word processing and spread sheet file structures would go way further to gaining windoze converts than a slightly faster widget bus.
If the MPC8540 is an early family member of the Apple G5 chip, the shipping date of the 8540 will tell you all you need to know.[/QB]<hr></blockquote>
OK, you got me, I never checked availability. But I still think it is a good place to look for what we can expect with the G5, due to the numbering of the chip and other similar technologies.

I read somewhere that the main thing (or one of them) keeping a lot of pc users from the mac is our slow memory and bus. So hopefully we'll get that fixed on the next revision.
*ATA 133
*G5 + faster bus, DDR RAM
*Firewire IEEE 1394b (that right?) @ 800mbps
*USB 2

I thought it was going to be 800Mbps over standard cables and up to 3.2Gbps over optical cable....

I just tried to look up more info and here is what I found:

Their ad slogan might be:
"Airport 2 and the NEW PowerMac G5 w/ Cappuccino: Stay wired without the wires."
Can we say BIG HIT? :eek:
