AMD Navi 23 ‘NVIDIA Killer’ GPU Rumored to Support Hardware Ray Tracing, Coming Next Year

Yeah our man Paul could not confirm the name he hinted it, so in that sense he is right if this is legit leak info coming through.

Surely we should have a ray traced hype train by now :)

Thats not the patent that is linked a few posts back it is the trademark. I had a post somewhere in this thread that linked to the patent and from memory it was filed early last year.

Edit: March 2019

The file date for infinity cache, via the posted tweet is 9-29-2020. There is no other inherent name given that I know of. Also when you look at the international class it's for private sector business applications.

Infinity Fabric? is the name AMD gave to its 2.5D stacking technology many years ago, in this case it allowed the GPU and CPU to share the same memory pool effectively making the CPU and GPU the same thing.

CPU's are very good with serial execution, GPU are very good with Parallel execution, by mashing the two together you get the best of both worlds and greatly increase performance. AMD call this technology Heterogeneous System Architecture (HSA)

It brilliant technology but unfortunately it requires developer support and Intel setting the trend for that won't have it, or at least they did.... Intel's dominance is changing.

IF, or Infinity Fabric is still in all new Ryzen CPU's, only now its used to connect chiplet modules together.

AMD are still pursuing this technology, it is the future weather Intel like it or not.


An example of what the performance looks like.

Much like the approach of extending an Infinity Fabric link between the CPU and GPU, HSA provides a pool of cache-coherent shared virtual memory that eliminates data transfers between components to reduce latency and boost performance.

I didn't read that their caching system was specific for 2.5/3d stacking. Which is why I believe that this may have a broader application then just RDNA 2. Even the patent alluded as much.

I'm not 100% on the correctness of this statement, 2.5D stacking and Infinity Fabric are, I think, very different. AMD announced some time back in March I think the details of their 2.5D stacking tech which if I remember rightly was called something like X3D. X3D, if I remember rightly was 2.5D stacked chips connected with Infinity Fabric. Infinity Fabric which released alongside zen only describes the proprietary system interconnect architecture that is Infinity fabric. The fabric itself is broken into multiple other bits of technology so IF is more the combined description of several technologies that fit together to make the multiple data planes that describe infinity fabric.

IF consist of Scalable Data Fabric (SDF) and Scalable Control Fabric (SCF) and within each of these Fabrics specifically SDF you have further technologies including a mechanism called Coherent AMD socKet Extender (CAKE) that ties it all together. Further to that there are two separate types of SDF which are Infinity Fabric On-Package (IFOP) and Infinity Fabric InterSocket (IFIS) so really as far as I can see it's only the name given to their interconnect that can link anything to anything coherently, so basically it describes a shared data plane built directly into it's processors, gpu's, whatever... All coherently working as one or Zen.

I am no expert on any of this so am happy to be put right but i've read quite a bit about infinity fabric as I find it particularly interesting. I also believe that the most ground breaking part of Zen was never Ryzen itself but Infinity fabric and how much of a game changer that is in terms of scalability, power draw etc vs something like say EMIB.

I'm glad he poo-pooed that rubbish about dedicating 20cu's to RT... I said a few days ago that it was bunk and RT was gonna be done in the same pipeline... Not saying Paul is the 100% accurate indisputable source of truth -- but that he reiterated where my understanding was seems to bode well :p

And as mentioned during the video, AMD's naming scheme will line up with NVIDIA, i.e 6800XT v 3080, 6900XT v 3090 and so on. With lower end SKUs coming next year.

Not long now peeps.

Still have 3 more weeks and change before RDNA2 announcement :( and we have no idea if we'll be lucky enough to get our hands on Zen 3/RDNA2 within a reasonable timeframe (2-4 weeks) after the announcements :( and I'd hate to see them pull a fake-MSRP bait and switch.

My dream of gaming on a Zen 3/RDNA2 system by the end of November might never live to see the light of day :(
