So, do we know anything about RV670 yet?

[_xxx_]

However, I don't know if overdrive can change the voltage?

SW-wise it would be easy, but controllable voltage regulators are way more expensive than the fixed ones. I say not, for cost reasons.

If Powerplay is that was AMD promises, it would be necessary.

I thought ATI had been changing voltages in 2D / 3D settings with their drivers for a while now

Ooops wait, they do have a digital power supply, right? That should be able to do it, correcting myself here.

Fully Dynamic (Now its clear why it is restricted to 825MHz in Overdrive)

That 3870 vs 2900xt performance slide, look likes no improvement in the drop turning on aa but in the other 4 games, what did they change as the performance is way bigger than the clock difference.

Yep, should be fully controllable.

The kookiest slides I've seen in a while...

RV670 seems to be doing alright in UE3. That's good news for me, gonna be playing UT3 24/7.

Perhaps, it seems that powerplay 7.0 corresponding.
This has the possibility that the back bias is used.

Interesting results those at http://we.pcinlife.com/thread-844605-1-1.html

I mean, there has to be some architectural improvements, if even 3850 is faster than 2900XT, even if it's just in one game (UT3)
Sadly, the 256bit membus seems to do a slight hit even though 3870 has only ~1/4th less bandwidth - slower than 2900XT in couple tests with AA/AF enabled.

I'm curious why AMD didn't replace Serious Sam with Crysis in their benchmark set.

The Inquirer has a picture of an R680 a.k.a. Radeon HD 3870 X2 card:

http://www.theinquirer.net/gb/inquirer/news/2007/11/09/inq-reveals-r680-radeon-hd-3870

As you can see, this longer board is on the trail of the 8800GTX/Ultra PCB. Unusually, there is no significant increase in the height of the board, meaning this dual-GPU card will fit it a more compact chassis.

The price of 3870 X2 will be between 399 and 499 USD/EUR, 249 and 299 quids (yes, life sucks in Bligthy).

RV670 chips are working at 750+ MHz each. 775 MHz should be reachable by launch time. Who knows, maybe even 800 MHz for the GPU. When it comes to overclocking, we have no idea at the moment, but the memory should be able to work at 2.25 GHz, yielding in combined bandwidth of 144 GB/s. Not too shabby.

[...]

Bear in mind that the G92_300 series, or D8E, the GeForce 8850GX2 or 8950GX2, whatever Nvidia marketeers figure it out to be - is also a dual-chip board. It is widely expected that Nvidia's card will be the same as 7900GX2 and 7950GX2, or a dual-PCB connected with 20-or-so connecting pins, all working in harmony with Nvidia's BR04 chip.

That's really bad photochop, heck, even for inquirer that looks bad imo, not to mention that the slide doesn't look the same either as the other slides, does it?

Why is R680 a.k.a as 3870 X2?

 

[Stenis]

Looks like it's gonna be a hard launch.

We have HD3850 and HD3870's already here ready.

Lets see some real benchmarks!

As always vr-zone kickstarts the party a little early.

Pretty sweet OC. And looks and the temps.

 

[Shtal]

Looking at this image benchmark!

Only when using 4XAA/8XAF I see 512bit 2900XT yields better then 256bit HD3870.

I have to wait for more benchmarks before make a conclusion.

To 860 mhz! Not too shabby on the stock cooler.

Not shabby at all. :smile:

416 shaders? Bug in gpu-z?


My next card for sure. I'm tired of hot powerhungry hardware.

More than likely, GPU-Z thought for few versions that my X1800XL had only 6 VS units, too
