R570's new PCB

POGE · Jul 8, 2006

ATI's R570 core will replace the crippled R580 cores ATI is currently using on their X1900 GT's. Along with this new core comes a new PCB. Until now, ATI has been using the same PCB for all its X1800/X1900 cards. The new PCB has two crossfire connectors that resemble Nvidia's SLI connectors, and should replace ATI's dongles that are currently used for crossfire. Other changes to the PCB include the removal of the army of voltage regulators you see on other X1800 and X1900 cards.

POGE, remember that news thread when ATI was gonna have internal bridge for CrossFire, and it looked like 2 SLI bridges together really close? That's what that's for.

Fixed.

Thanks for the good info, theINQ had me false informed.

(not the first time)

Hmm, i wander how the voltage is regulated without the vreg's and fets then?! I hope it doesn't affect vgpu adjustments, i.e. limiting maximum voltage and current draw.

POGE · Jul 8, 2006

There is one vreg, instead of a whole line of them. And it isnt sinked. Its up in the corner.

At least when people want to do CrossFire with X1900GTs, they don't need a Master card and use only half of it's power.

I think there may be more on the back of the card than what meets the eye.

Your probably right... one doesnt seem like near enough. Can you find any more pictures?

It actually looks like they shifted to a digital Vreg. :eek:

Can't believe they beat CPU's to the punch with this one...

POGE · Jul 9, 2006

Maybe... but if you look up in the corner you can see what is obviously a single vreg... (non digital...) Just like the row you see on the other cards. But then again, if you look at the bottom, it is what looks like a digital vreg... hmmm.... maybe it uses both? Maybe one for mem and one for core...

it may.. there are 3-6 different voltages flopping around the card at all times..

it looks just a little shorter

Maybe they've gone digital.

I seem to recall motherboards loosing huge amounts of voltage regulation equipment with the recent replacing of the array of MOSFETs with the newfangled digital power regulators.

Smaller, more effecient, and I think more stable; it could be that they just managed to get rid of most of the pulse chips that way.

jbizzler · Jul 9, 2006

I see whay they did this to the X1900GT first. In order to get to get CF with the current X1900GT, you need to pair it wath an X1900CF, a much more powerful/expensive card. I hope R580+ incorporates this.

And I think the bridges will come with the cards for two reasons:
Crossfire motherboards don't come with bridges like SLI does:
There's two bridges.
Tell me if this idea is flawed.

hi: i wont to ask you how did you make your amd3200+ to work on 2.65Ghz
for the internal bridge that look like 2 SLI i agree

KennyT772 · Jul 9, 2006

well im guessing each crossfire compatible card will come with a flexi bridge as placement is different on many mobos. the hard pcb ones are better so maby mobos will start shipping them when this becomes the default method

zekrahminator · Jul 9, 2006

I think that they should ship a tweaker version of video cards with little knobs for Voltage regulators

he overclocked it... i can get my 3500+ to 2.75ghz

Azn Tr14dZ · Jul 9, 2006

Thanks for answering for me Drew.

Anyways, elesar, my 3200+ is, or at least was, running at 2.65GHz 265x10, but since I'm having heat issues, I lowered it. I guess I only use that speed now only for benchmarking.

np

.... yeah i dont run mine at 2.74 either but it runs at 2.55 stock v's stable i love it

RickyG512 · Jul 10, 2006

is this faster than the X1900XT

and where did my quick reply box go, and yea i was allready signed in but its still not there

RickyG512 · Jul 10, 2006

is this only as fast as the GT or XT iswell

BigD6997 · Jul 11, 2006

its the same stuff as the other x1900's just a different pcb, so its as fast, maybe faster cuz they might have taken stuff out of the way and made it more efficient
