Tonopah is mentioned as well. Area 51 is like a tourist attraction, so anything ultra classified is unlikely to be there. Worrmholes are theoretical Einstein-Rosen bridges, and they haven't been observed in nature unlike antimatter, which has been produced by humans. The exotic matter...

Where did you get that number from? I would be more inclined to go with no anti-gravity testing as that hasn't been theoretically addressed to be viable, whilst anti-matter at least has been produced.

These seem to be the most common footage these days, and also seem to be the easiest to fake. If they are overlaid with a military HUD system, with additional captured signals, then people seem to take them more seriously. Yeah, I doubt any of these footage will have a pristine source with all...

Yeah, I've used the following downloader before: https://9convert.com/en1 Just paste the YT URL to prepare for MP4 conversion and download.

With all the recent talk of UFOs/ UAPs/ ETs and government reports, I stumbled upon some footage. Most footage are blurry blobs and complaints about unclear videos not being available in this modern age. But when there are clearer footage, usual fakery with CGI/ models/ puppets are claimed. I...

Yes, the Raster Unit is determining the peak geometry rate, but I am discussing the change in fragment output per triangle from 1-16 for RDNA1 to 1-32 fragments per triangle for RDNA2, more specifically the Scan Converters. In the other thread, discussion went: - Navi 21 (RDNA2) hss 8 Scan...

Are you using 'rasterisers' and 'scan converters' interchangeably? Given a Shader Engine, there are 2 scan converters in 2 Shader Arrays, and the Raster Unit sits above SAs at the SE level processing 1 triangle. It isn't clear how we are getting 1-32 fragments still from 'coarse' and 'fine'...

There seems to be definition vagueness. We know that the Raster Unit spits out 1-32 fragments per triangle. There are 2 scan converters involved from the driver leak. The 'coarse' and 'fine' arrangement of scan converters (rasterisers) are not detailed. We are speculating on how we get 1-32...

PS5 has 64 ROPs (Github), so its pixel fillrate has increased from previous gen and is plentiful: 64x2.23GHz = 142.7 Gpix/s Triangle throughput: PS5: 2x2.23GHz = 4.46 GTri/s (if 2 tri/cycle for RDNA2) PS4 Pro: 4x0.911GHz = 3.64 GTri/s Triangle throughput has also increased from the PS4 Pro...

Yes, you can easily get lost in all the nomenclature. I've clarified this before and will reiterate. The driver leak, Hotchips and Navi21 block diagrams make this clear. Don't get lost in all that nomenclature as above. It's really simple: RDNA1: 1 Raster Unit = 1 Scan Converter working on 1...

For Navi21, my explanation for this weirdness lies with the 2 Scan Converters working on 1 triangle. A coarse and a fine scan converter, which we don't have much detail on their operations besides converting 1-32 fragments for each triangle. Each Raster Unit has 2 scan converters, and from the...

No problem, thanks. https://forum.beyond3d.com/posts/2177723/ Above is discussion using 2 scan converters per raster unit, a coarse one and a finer one for smaller triangles. I don’t expect high performance for 1 fragment sized triangle, however, I expect better performance than RDNA1. And a...

Navi22 disagrees. It's a mid-range 40CU, highly clocked GPU with a narrower bus than the PS5. Console GPUs are comparable to mid-range GPUs at launch. For a given cost and power budget, Sony chose something similar with PS5, where narrow and fast is a relative statement. This isn't a statement...

Yep, your thoughts here were pretty much my thoughts when I first saw the driver leaks last month, and didn't think much of them and brushed them off. However, back then, we didn't have RDNA2 details and block diagrams for Navi21. We have the details for XSX and block diagram from Hotchips. And...
