I don't believe the D3 and the Atrix have the same type of Pentile screen. I believe the D3 (and DX2) has a RGBW pentile display and the Atrix has a RGBG display.

We'll know for sure when Anandtech releases their review of the D3.

Atrix's RGBW as well. Since you refer to anandtech - AnandTech - The Motorola Atrix 4G Preview
RGBW or RGBG - pentile is pentile - one pixel on a pentile screen is formed by less than one physical color group.
That's where power savings come from - at this resolution there are 33% less pixels to control compared to classic RGB stripe display.
I've read that review several times...where do you see that they claim it's RGBW?
This is from the DX2 review:
RGBW is a different layout with different purpose, and dare I say different results.
On webpages, RGBW actually looks pretty good, with black text being nice and sharp on a white background. This is one place where RGBG just never could do a perfect job, but RGBW does. I actually have no problem with RGBW for black text on white backgrounds.
In our tests, the X2 results definitely show how much having that white subpixel can help.
Notice how far down the Atrix falls on that graph?
Also, here is the pertinent text from the Atrix review:
Note the ordered grid structure of the subpixels in the iPhone 4's display vs. pattern on the Atrix. PenTile is usually most bothersome when reading text - click the images to see them at full resolution.
Personally I was bothered a bit by text rendering (particularly aliased text on zoomed out web pages) on the qHD screen. For the most part, the qHD display was pleasant to look at and its PenTile upbringings didn't bother me.
Looking at the macro shots it's hard to tell because they aren't shots of the same color, so that's not definitive. But clearly "pentile is [NOT] pentile" as you suggest.
