Okay...
| fatslob-:O said: because in the long run games are starting to be more optimized than ever before on GCN |
So... Either Architecture matters or it doesn't?
| fatslob-:O said: Nvidia by their own admission with Turing, a good amount of bloat in it's silicon are probably due to the features that GCN already had. There's lot's of things that Nvidia changed with Turing to be more at par with the feature set of GCN such as it's more flexible memory model (not even Volta has this), access to barycentric coordinates within pixel shaders, async compute, and the scalar unit so it's no big loss that next gen consoles are going with GCN again when indirect competition (Nvidia) is taking a similar route ... |
Maxwell, Pascal and Turing have a plethora of techniques that simply gives nVidia a massive step up in regards to efficiency... These were all lessons that nVidia learned whilst building Tegra.
Things like Asynchronous compute are in the Xbox One/Playstation 4... And on the PC hasn't really translated into AMD having a leg up over nVidia in the PC gaming landscape by any meaningful denominator.
| fatslob-:O said: There are still some things Turing doesn't have compared to GCN like rapid packed math or shader specified stencil values ... |
Turing has Rapid Packed Math... Or rather, nVidia's version of it.
Hence why Turings half-precision is double it's single-precision in theoretical flops.
Even some Pascal parts had it.

It has also been a feature with Tegra for awhile too. Rapid packed math as AMD calls it, is AMD's marketing term of packing two FP16 problems together.
| fatslob-:O said: Don't worry about consoles since developers on that platform seem to have an easier time matching Nvidia's equivalent theoretical performance. I don't think performance will be a concern because it's the developers job to figure out the fast/slow paths of the hardware they're working on. Sony could very well do some amazing things with a Radeon VII at hand because of the fact that they have better tools than available on PC ... Reaching RTX 2080Ti level of performance isn't all that far fetched depending the fast/slow paths each hardware is hitting relative to each other ... |
Metro on PC is a step up over the Xbox One X version on Turing-equivalent hardware.
Consoles can punch ahead of PC equivalent hardware, that holds true whether you use nVidia or AMD's solutions... But the precedent is already been done and dusted... Despite games being built with 8th gen Graphics Core Next hardware in mind... nVidia still holds a seriously catastriphic advantage over AMD in almost every regard... With the exception of price.
