Your CPU wants to help with ray tracing as well?

   So Nvidia’s software
   So Nvidia’s software Engineering/Drivers Engineering folks are helping the games developers in getting their games/gaming engines tweaked for RTX/Turin’s Ray Tracing and Tensor core IP.

   I have also seen Games/Visualization workloads run on Titan V’s and Teslas where Ray Tracing was accelerated via the CUDA cores! That’s The Pre RTX GPU way of acclerating with Ray Tracing/BFH(bounding volume hierarchy) calculations on GPUs that lack the Hardware Ray Tracing IP that Turing has.

   This is going to be done via Microsoft’s DXR where you just know that Microsoft will have 2 code path in DXR, one that will either make use of RTX/Turing’s ray tracing hardware or the other that will go the software/GPU shader cores path for non RTX enabled Nvidia/AMD GPUs.

   I’m going to be looking at RTX/Turing more after Blender 3D/other open source software get their code refactored for CUDA 10(required for RTX/Turing support)! And hopefully Nvidia will port RTX/Turing’s Ray Tracing support over to Nvidia’s Version of OpenCL/OpenGL also because there is still plenty of non gaming graphics software that still makes use of the older graphics/compute APIs.

   So I’ll expect that Microsoft’s DXR will offer an alternative Ray Tracing code path to allow for some more limited games Ray Tracing via GPU Shader Core acceleration on Pascal/Vega-GCN GPUs! Microsoft does make use of AMD’s Semi-custom APUs for XBOX consoles so DXR will probably be there also.

   Hell just looking at the 8 core Ryzen 3000/Matisse desktop variant’s die shot from Today’s AMD/CES live blog gets me to thinking that maybe MS could just order a semi-custom Vega-2 Die-Chiplet/MCM and fill out that empty space on the Ryzen 3000’s MCM and get some sort of next generation console variant from that. The Ryzen matisse 14nm I/O die could be customizied for MS/Console use to support GDDR6 or even HBM2, other MS console specific IP. MS could even have AMD add in some Tensor Core IP that’s tuned for AI based Upscaling and get MS’s Next generation XBOX consoles closer to looking like 4k native. All the cell phone SOCs are getting Tensor Cores(Neural Processor Cores) and that Modular Chiplets thing is the next wave as even Intel is getting into that game.

   It seems noone told Nvidia
   It seems noone told Nvidia that precise / raytraced reflections make no sense whatsoever in multiplayer games on a 2D display:

   1. If I point game camera at a glass which should be in focus: what is behind the glass or reflection?

   2. I play as a Scottish solder in a traditional kilt and I stand in a puddle. I look straight down. What do I see?

     A true Scotsman.

     You’re missing the point.
     You’re missing the point. None of these “articles” that you see on PCPer and elsewhere are overly concerned with “ray tracing”, it’s just a pretext. These are all just native ads for the game “Battlefield 5”, which has been selling poorly in comparison to its contemporaries since its launch. EA has been so desperate with this game, it was on sale a week after launch, which is a bad sign for a AAA title from a major studio (DICE). Also, like some other titles, it’s be given away with many different purchases on NewEgg.

   Now try the same tests with
   Now try the same tests with CPUs closer to those used by the majority of gamers. A lot of folks seem to think that their i5-6xxx will likewise be unaffected by RT, yet your little test between two high-end CPUs does reflect the reality that many gamers use something less expensive than an i7-7xxx series. Many who came here did so to find out if *their* CPU will become a bottleneck with RT on.

     Well, seeing as how

     Well, seeing as how [H]ard|OCP doesn't exist anymore there is not much point in telling them; now is there?
