Maxwell Blur Analysis - Will Geforce 800 Series ship with New Reference 'Dual Axial Turbofans' Coolers?

Note: Earlier we begin,  anything mentioned in this Editorial may or may not be fact and is educated speculation. As such, this was done simply for a scrap of fun and It would be best to care for this editorial on face value alone.

[Editorial] You may recall the revelation by Gigabyte's manager that the Maxwell Geforce 800 Series is landing quite soon, but you probably missed his passing comment on the fact that at that place are going to be new custom coolers on the PCB. That would ofcourse mean a factory overclocked GPU only maybe, the new cooler isn't going to be present just in the Gaming G1 series? Looking past at the hints in that location'southward actually a reasonable gamble that Nvidia might introduce a new reference cooler design: Dual Centric Turbofans.

Maxwell Blur Analysis - Possible Geforce 800 Serial New Reference Design - Dual Centric Turbofan?

On May 15th of 2022 Nvidia filed a patent with the ID number US20140133082 A1. This particular patent protected a very special blueprint, namely an Centric Turbofan. Whatsoever experienced gamer would immediately notice that this design is quite different from the blower fans Nvidia ordinarily uses in its reference cards. Talk of this patent died after the usual hue and weep. A few days later leaked pictures of the Maxwell Geforce GTX 880 PCB surfaced where two parts in detail were blurred out. Still, in that location was something Hassan and I noted: there appeared to be something very familiar in the blurred out portions on the right side of the PCB. The blurred out section appeared to draw two blackness circular objects aligned at the right edge of the PCB. Could this be the new reference cooler for the Geforce GTX 800 Series Gigabyte's Marketing Director was talking about? Since I want to brand sure you guys follow me, its time to whip out my trusty sometime Photoshop.

Now I am working on a very low resolution because of the depression quality pictures and then virtually of the additions I make will appear blurry as well. The commencement matter I did was take the Nvidia cadre visible in the moving picture and start applying a Pixelate (Mosaic) filter and increasing the intensity at ane point intervals. I did this to opposite engineer the Pixelate intensity that was used, and at a cell size of exactly 19 points my square pixelated artifacts were exactly the same size every bit the original pixelation. Now I learned two things for sure: ane) The intensity of the pixelate used and 2) the object is clearly round since a square object produces a very different pattern. Armed with this very useful information, I began my experimentation. The first thing I did was open the patent and try to recreate the design from a top view. I ended upward with a self created top view of the fan assembly and though information technology was nothing just a very crude imitation of the same, it will practice. There is ofcourse one very major problem with this entire concept that I am certain many of you accept figured out by now. Fans are usually non fastened like this to the PCB and in that location is a dissever layer between the fan assembly and PCB. However, since this is a prototype board (where anything can happen) and nosotros are doing this for some fun anyways, I am going to ignore that.

At present I am slightly unhappy with the placement of the fans because the lesser ane is on the edge of the GTX 880 PCB whileas the superlative one has a lot of breathing room. However, I am going to refrain myself from tampering with the placement and just go with the menstruation. I immediately noticed another problem with this particular organization. The design is supposed to button air out of all outlets and that ways that 1) in that location is going to be pressure cancellation betwixt the two fans and 2) air will be wasted  because some of it will exist blown back and out of the menu. I am non certain how this would work in a reference cooler for the Geforce 800 Series only if this is true, I am sure the peeps over at Nvidia R&D know amend. I wanted to run across how the pixelation blueprint looked so I applied the 19 Mosaic Pixelate filter and got horrible results.

I wont carp posting that here. The problem ofcourse is that the pixelate algorithm works on the colors present in the space and there is only one hither. The algorithm works by looking at the color range present in the infinite then manually filling in solid colors wont help either since in a real photograph, at that place is a very wide range of shades of the aforementioned color (thank you to lightning). The answer to this problem is actually quite uncomplicated. If i requite the filter a reasonable approximation of the color space I will become a reasonable issue, regardless of the object in question (the drawn fan) beingness quite different from its real life counter role. So I practical gradient based shading to the fans. The result was much better than last time just something was still missing, so I added a color slope for the PCB and the inner associates too and got the following results:

Now here'due south the thing. There is no way on earth I can accurately reproduce the same design unless I know exactly what the background Prototype is. This is why what I was actually looking for during this test was to get the bones pattern to lucifer. Since I continuously used color gradients to requite the algorithm the color range you would get after factoring in ambient occlusion, lightning etc, it should give the Pixelate algorithm approximately the same colour range to work with.  And after adding in the terminal gradient, I recollect I have a pretty close match. If yous alter the lightning a little, yous should become an almost identical pattern to the one shown in the PCB shot of the Geforce 800 Series GTX 880. So what exactly have we learned? The but matter we learned for sure from our analysis are the following: A nineteen Betoken Pixel Filter was used over a completely circular object with a blackness- green color infinite. We cannot say with 100% certainty whether these draw the new reference coolers for the Geforce 800 Serial or non merely I certain am tilting that way.

At the finish of the day the unproblematic fact remains that this could very easily be something else entirely. It could always be something that came out of nowhere just I don't see what else would need to be blurred out like that. Information technology could exist two ARM Cores (in a round assembly?) or a new defended power supply system (in two circular and identical blocks?) but to me, those seem a bit far fetched seeing the mistiness pattern. Both these things could all the same be present on the PCB even if this does turn out to exist the new reference libation blueprint for the Geforce 800 Maxwell GPUs. Logically speaking, the but reason I chose to practise a opposite-Blur Assay with the Fans is because at that place are exactly ii of these instead of one.
