400MHz EV6 bus, USB 2.0, and IEEE 1394 from AMD
- Thread starter NFS4
- Start date
why must u leave us hanging?
"The Frontside Bus (EV-6) is moving to 266Mhz on the 760 chipset, it will be moved even higher to 400Mhz (the EV-6 maximum spec) on a future chipset, we were not given a specific date, but were led to believe 2h 2001. The North Bridge is being relabeled as the 'Memory Hub', and the South Bridge is now called the 'I/O Hub' , also rather oddly, Flash Ram is now relabeled the 'Firmware Hub'"
for those of you who need a taste..
interesting. it seems they are reorganizing the whole architecture..
USB 2.0 I don't care about, but Firewire certainly sounds interesting..
finally though, I'm skeptical about the performance of this reorganization of devices, so I won't say whether it's a good or bad thing till I see some diagrams.. the way they put it in this link, it sounds kindof bad, performance wise, because it's talking about having to go through devices to get to the memory hub..

There's always gonna be a better upgrade on the horizon. If we all waited for the next best thing we'd still be using 486's with monochrome monitors.

do yuo know something I don't? hehe.. how do you know Firewire products are going to be expensive?
man, NFS4, intel LOVES you. you make CPU's look more important then they should be.

Just curious, why do you not care about USB2, but like firewire?
USB2 is faster and it's more geared towards computer peripherals.
Firewire is cool, but it's more a general home electronics type connection.

where to start.. first of all, USB sucks your CPU power.. you know how we've been moving towards Hardware acceleration in many things? well USB is the Opposite of that. your PS/2 port vs a USB port for a mouse is a perfect example of that. as soon as your CPU becomes busy doing something, if your mouse is in the USB port, it can become choppy, becuase it requires more CPU time to do the same thing.
ok, soon it will have extremely high bandwidth available. you know what this means? it means that Intel will actually be able to PROVE that having a faster CPU will increase, say, your internet performance, becuase the more that is done through your USB port, the more CPU time is needed. you get my drift?
Finally, Firewire isn't going to be like that, AND, as I've said many times in the past, you will be able to connect it to camcorders, stereo equipment etc, becuase Firewire is going to become the next standard for connecting home audio together (your reciever, CD player, DVD player, even your speakers would be connected using one strand of wire. all data is transmitted digitally, like the toslink, or SP/DIF connectors, except this will be for EVERYTHING).
SO, Firewire has the advantage when it comes to CPU time, and can be great for people who want REAL home audio on their computers too.
the only thing I feel that USB is good for at the present, is the Joystick. I see USB as a good temporary port for printers, and scanners, but even they use a fair amount of bandwidth.
do you understand now? it's like doing the reverse of Hardware T&L. going BACKWARDS in time, slowing down your computer, rather then speeding it up.

USB is for my computer.
firewire is for connecting stuff to my computer.
stuff = {audio, video, etc}

"The LDT bus runs at 800Mhz, and 1.6Ghz clock rates, which means it can move 6.4 Gigabytes of data per second each way, 48 times the bandwidth of, and at a lower latency then the current PCI bus..."
Holy sh!t! Can we say "Goodbye PCI"?
Does anyone know what kind of overall system performance gain we could expect from moving from 33MHz to 800MHz, and lower latency?
Do you think this is also an AGP replacement?
Firewire is superior to USB in many ways. I will be supporting FW 100%.
IEEE 1394 is 400Mb/sec. IEEE 1394b is 800Mb/sec. Suck it, USB.
As NSF4 states, USB 2.0 is 480mb/sec.
When will we be seeing IEEE 1394b?

LDT is goddamn impressive, no doubt, but there is a problem. It is AMD patented. Meaning INTEL, the market leader, will be pushing AGP 16 against it or something, and i seriously doubt companies are going to make LDT *AND* AGP cards, along with the occasional PCI.
did somebody already mention DDR SDRAM? i'd call that a double take... oh wait... i guess PC133 ala i815 would be a double take as well
before gawking at this 800mhz speed, you might want to look at the topology first.. what they describe isn't clear enough for me to draw any conclusions as to how efficient the design will be, especially compared to todays chipsets.
what I'm saying is that we don't know whether it's like having 100 computers all connected to the same wire for a network, or if they have a hierachical design, which includes other network devices that help clean it up (switches, routers, etc). until we know what it looks like, we can't tell if it's going to be good..

<< Leading the Development of USB 2.0
The companies that are leading the development of USB 2.0 have the expertise needed to focus on a specification that supports higher functionality peripherals. The USB 2.0 core team includes four members of the original USB core team (Compaq, Intel, Microsoft, and NEC), and three new members (Hewlett Packard, Lucent and Philips). As with USB 1.1, members of this promoters group will not charge royalties for essential patents required to implement products compliant with the USB 2.0 specification.

And AFAIR, as long as a company refers to it by the specification name
IEEE 1394 and not as "Firewire" they owe no royalties to Apple either.

Ouch...I didn't know that...
I knew USB mice used more CPU power than PS/2 mice but I thought it was just because it had a higher report rate...

Thanks for the info soccerman.

didn't know that.. but it kindof makes sense.
you're welcome Noriaki.

Interesting! Sounds like USB2 is like IDE in that it sucks more from the cpu and Firewire is like SCSI, so to speak.
I'm very curious how much of a performance increase the 400mhz bus w/ DDR ram is gonna make? Any educated guesses??
