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

Here's hoping the info on expected performance is roughly accurate, would be nice for consumers to have multiple options across the range of cards. The cache I find most interesting (again, if true).

It makes the most sense as gddr6 vanilla seems a weak sauce. Drivers are out now that have gained the 5700XT lots on the 2080Ti which would warm toward squeezing more performance out. Slight improvement in IPC + 50% efficiency + higher clocks is a solid indicator that its 3070/3080 territory IMO.

Some of the Nvidia fans just get irate and upset when someone suggests AMD may release a killer product. His video seems to suggest we will have a nice choice of gpu's this fall which is good news for competition and the consumers. I hope he is at least half right.

When MLID was releasing info on Ampere stating it was going to be really good. They all loved him. As soon as he mentioned that Amd might have a good product (this was the performance metrics that nvidia thought amd would achieve) they all immediately dismissed him as unreliable.

I need to go back and review MLID, leaks to see how close or far he was.

I love watching people flip flop when it comes to stuff like this . It is the reason why I want AMD to smash it out of the park. So I can watch the entire internet freak out. I'll need to buy snacks for the launch event. Either way it will be interesting.

Not very though he had/has videos covering most angles - he claimed a bunch of new feature technologies that at best are tenuously similar to actual new tech in Ampere, his initial claim was his reliable source apparently claimed TSMC 7nm would be used for the 3080/3090 (I can't remember what produce numbers he used but basically pointing at those tiers) and Samsung 8nm for the lower end cards, then that changed to TSMC 7nm through the stack then eventually Samsung 8nm, etc.

EDIT: His "full" leak and IMO what he should be judged on as it presents some degree of exclusivity whereas the later information that is more correct is posted after the fact when other reliable sources have covered it: https://www.youtube.com/watch?v=oCPufeQmFJk

Top end GA102 card would be 220w, 2.2GHz clock, 864GB/s memory bandwidth, 5376 cores, built on TSMC 7nm, come with DLSS 3.0.

I'll leave the audience to decide.

Little bit confusing this. Is the graph that leaked a day or so ago showing projected performance trustworthy? This had it on par with a 3080, or just below. But other reports are now saying it could beat the 3080 and get closish to the 3090.

Between a 3080 and 3090 is what I really want. I am getting very impatient waiting for a GPU.

*Not using 512bit bus. Lower Bus width
*Infinity Cache on the GPU 128MB which helps make up for the lack of memory bandwidth of GDDR6
*80CU for top sku
*Hybrid Ray Tracing (AMD Patent)
*Up-sampling handled via lower precision operations.

That's great news. Few questions:

a) don't still understand how lower bandwidth can be managed through higher cache. Won't it make more sense to increase the bandwidth for better utilisation of larger cache?

b)80 CUs.. so is it 128 ALUs per CU now just like Nvidia doubled their count per CUDA core? That should be too good to ignore.. any info from console teasers?

c) Any side by side comparison between hybrid ray tracing and nvidia's approach?

d) what's that last point?

RDNA2 GPU spotted in AOTS

the score is within spitting distance of the 2080ti

it's not known what model card this is

63.9 FPS at Crazy_4K for unknown Radeon Graphics.
RTX 2080 Ti - +1.6%
RTX 3080 - +38%
RX 5700 XT - -19.4%.

This should be a small GPU, maybe Navi 14 replacement?

The funny thing with all of this is everyone needs AMD to launch good cards. Fanbois on both sides need it. Nvidia loyalists will always go green and need lower prices and higher tier cards, 3080Ti. AMD worshipers need decent performance and also the competition that brings affordable technology. We should all be celebrating if they're neck and neck.

I'm curious to see what this cache thing is all about. Could this be something like the Broadwell 128MB eDRAM I've heard mentioned?
