RX 480/470 PCBs spotted

Djole123

So, we're all hyped about Pascal and Polaris, but I'll bring some more. There is leaked picture of the 480/470 PCBs, so let's have a look.

amd-rx-460-470-hands-on-3-1.jpg

So this is an SFF card. It has 8 memory modules (presumably 8GB of frame buffer), it's running off a PCIe x16 slot, it has, I assume, a single 6pin power connector, and it features 3 DP ports and a single HDMI 2.0 port.

 

I think this is a pretty damn poweful card considering its size.

Well, Lisa Su did have the bare PCB in her hand (alongside that puny RX460 with that cute little cooler on the thing), this is just a higher-res image of the same thing. And yes, that's a single 6-pin power plug.

 

I do wonder if the cooler on it becomes an blower-style e-peen extension just like on the 480 or whether AMD goes R9 Nano-style on us with a big fan in the middle and a big linear heatsink.

Ye ole' train

Traditional AMD 6+1 power phase. Nice.

Is the picture given above of a 470? Because I remember when Raja Koduri gave a 480 to Linus in the early look video before Computex at Macau in China, they took some b-roll shots and the 6-pin appeared to be almost in the middle of the card, or like two inches to the right from the middle.

The cooler had penis extention so maybe that's why it seemed that way. 

Slowly...In the hollows of the trees, In the shadow of the leaves, In the space between the waves, In the whispers of the wind,In the bottom of the well, In the darkness of the eaves...

Slowly places that had been silent for who knows how long... Stopped being Silent.

Really? Why would the cooler need penis extension?

More heatsink surface area

Allows overclocking of even a reference card

Well tbh i have issues with calling this a leak.


The rx 470 is clearly in view, sadly it's not as clear as the picture but stuff like vrm, ram, 6-pin and other stuff are clearly visible soo yea....

Actually i'm suprised they didn't say anything about the rx 460 which is also quite clearly in view.

If you want my attention, quote meh! D: or just stick an @samcool55 in your post :3

Ok. From a very basic standpoint the power phases are like the firing order of the cyclinders in your car. 
For instance, if the board (or graphics card) has eight phase power, then the incoming voltage from the PSU is made available to eight buck converters* (each being a transistor to take the voltage load from the PSU, and 2 switches that alternately charge and discharge the load from an inductor) - so these eight converters fire through one cycle (i.e. at 45° if one cycle equals 360°) through their seperate switches, and are rejoined into a single board input. Technically, dividing the incoming current through seperate switches/phases reduces heat and voltage drops... So, the more converters (or phases) then, theoretically, the cleaner the input power since you have incoming power more times per cycle -less opportunity for current drop between discharges.

Using the car spark plug analogy, it would be akin to an 8-phase board being a V-8 engine, while a 4-phase board would be an in-line/V-4 .

I think the blower being longer here has a valid purpurse: since it feeds the fan from the back this means you don't have to cut the pcb the fan is just past the end just like the Asus turbo or gigabyte non reference blower design for the 970.

 

Edit: actually no speculation this is precisely why : 16081755923l.jpg

But it also makes the card longer, something that's not desired in HTPCs and SFF gaming rigs.

Given the 470 supposedly uses about 110 watts under load, maybe the AMD reference cooler won't be a jet engine this time.

On this image you can see the 470 appears to be smaller than the 480. But that's only the reference cooler, there will be other versions.

So that PCB may be the 470?

I think the PCB for the 480 and 470 will be the same, or very similar, they are both based on polaris 10.

In some tiny square style ones sure. But in some thin sfx style ones like the Raven RV02, fractal node 202, etc. This is actually a lot better than a tiny cooler: many itx enclosures kinda need a blower. 

 

This way the reference pcb is short and can be swapped by vendors for something smaller as needed yet its still reference in case you want a waterblock. 

 

Win Win if you ask me. (win win win if you get that reference you earn a cookie)

It's already a short card tho

The back of that rx480, there is a 8 pin port near the fan. Must be for something, like rgb backplate :D

I wonder if they will release rx 460 without any power connector. I hope there will be a low profile version without power connector. So, I can fit it in something like Dell optiplex 990 sff.

The card Lisa Su held up at E3 in her left hand was an RX460, and it had no additional power plug. It was also single slot, judging by the puny cooler and the single I/O slot on the back of the card.

I'd also love to see what will Pascal offer with the GT 1040, it should be an SFF card aswell.
