AMD RDNA4 Architecture Speculation

[RedVi]

Surprised to see Funco Fusion on that list considering it flopped and they are laying off staff.

10:10 Games reportedly affected by staff cuts

Funko Fusion developer 10:10 has reportedly been hit with layoffs, with around 20 workers affected.

If the game already has FSR3.1 support then no work is required by the developer as per the videocardz.com article. It's a driver side switch.

I wish AMD had made the change to a dll model with FSR3 and not 3.1. It would have made FSR4 support a lot clearer.

Half of the 30 games listed are low budget games anyway, some of them don't even need any upscaler (maybe for low budget GPUs?)

If the game already has FSR3.1 support then no work is required by the developer as per the videocardz.com article. It's a driver side switch.

Looking at the list, it's not true, the FSR3.1 supported titles are much larger than this list (~50 games). The games still need to be patched for FSR4 support.

It's worth noting that Navi 48 is possibly on TSMC N4 (or maybe some derivative). Nvidia's 4N despite the naming is a customization of TSMC N5.

All "4" TSMC processes are in fact derived from N5.

It’s probably a similar situation to dlss4 and AMD is whitelisting games that they’ve tested on fsr4.

So still no BVH traversal in hardware? Instead we get one more intersection engine? Am I understanding that right?

Yes, it's a beefed up original solution so it will still be slower than Nvidia's and Intel's but the gap will be smaller.

At 22:40 mark: "Dynamic register allocation..."

Optimizations for better VOPD handling?

The 9070 non XT is 550$ which is the same MSRP as the 5070 .. doesn't make any sense .. users will prefer the feature rich 5070 at the same price, and even at a 100$ higher.

The 9070XT is debatable, it's ray tracing performance is still lacking compared to 5070Ti (the 5070Ti seems 20% faster), and lack many NVIDIA features ... so ... (shrug).

True, but then the 9070 does have 16 GB vs the 5070's 12 GB. It's been propped up as a psychological barrier.

And then IF you decided to go for the 9070, well why not scrounge together the extra $50..

Looks like the 9070 XT might be 10% behind in light to moderate RT workloads (eg. console ports).

AMD now acknowledges the era of Path Tracing (timestamped), they presented a demo with ReSTIR and Neural Radiance Cache.

9070XT is @340W, meaning overclocked.

9070XT is @340W, meaning overclocked.

In the presentation, they had commented that for the $150 difference, you would only lose 2% performance, but that third-party manufacturers will have overclockable cards that will add another 4% performance.

We are seeing some positive advancement in not strictly defining the BVH structure in the DXR specification.

That's 2% w/o RT presumably which will be more like 10-20% w/RT so the price difference this time seem to be based on RT comparisons - which is good and basically how it should've been starting with RDNA2 I'd say.

That's 2% including RT. The question is whether "RT Ultra" and "RT" difference between the comparisons is intentional or not, which could push the OC model to about even instead of +2%

 

[DegustatoR]

That's 2% including RT.

This is not what their own numbers against 7900GRE are showing at all.
