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...
Are you using 'rasterisers' and 'scan converters' interchangeably? Given a Shader Engine, there are 2 scan converters in 2 Shader Arrays, and the...
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...

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:...
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...
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...
No problem, thanks. https://forum.beyond3d.com/posts/2177723/ Above is discussion using 2 scan converters per raster unit, a coarse one 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...
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...
Well, CUs do SIMD and Scalar computation and are fully programmable. The Ray Accelerator is a fixed function block and acts as the Intersection...
I posted details a few pages back. Here's my post, where I started discussing: https://forum.beyond3d.com/posts/2178977/ Poster, @Digidi...
No, I don't agree. This thread has in its title "speculation". I haven't seen any discussion around the driver leak and relevant patents (mostly...
The final numbers are correct, however, the formula is incorrect. ROPs aren't used to calculate CU floating point capabilities as they are...
It is not to say that the location of the Raster Unit is better or worse, but the change from RDNA1 to RDNA2 is better. And by better means RDNA2...
