AMD RX 6000 Ray tracing

[letsplaysims3]

I watched Steve Burke's video on his review after yesterday AMD announcement.

 

If I get him correctly, the RX 6000 series compute units will be doing the ray tracing rendering tasks. Is that supposed to be hardware driven?  Or the whole ray tracing process is purely software driven?

afaik it is directx raytracing

That's what I do not understand. What is DX Ray Tracing?

to put it very simply it is software raytracing which almost every semi modern gpu can do

Hello,

 

DX Ray Tracing is an extension of DirectX 12 developed firstly by Nvidia and now used by AMD too.

Is RTX doing software raytracing also?

no it has dedicated cores to do so

Oh, that's ironic!

 

So, RTX series are also using software raytracing?

The RX 6000 series also have dedicated raytracing accellerators. 1 for each CU to be exact.

Oh!

So logically speaking, and by deductions, AMD might probably suffer from a FPS bleeding when raytracing is on?

It's always software ray-tracing. The question should be if the cards have hardware-level acceleration. And yes, both the RX 6000 series and the RTX 3000 series have that. But currentyl it's unclear if AMD will suffer more from turning on ray-tracing or not.

one can assume so. but its not like that isnt allready the case with any current raytracing capable GPU.

Yes, that's what the technical guy mentioned in his speech during the announcement. I clearly recall the word accelartor.

Thanks for helping me with the rhetoric here, that's what's I meant

That's true. That's why we have to wait for the benchmarks on youtube and other websites' reviews.

It's gonna to be hot!!

[letsplaysims3]

So, AMD's raytracing capabilities is also hardware accelerated, am I correct?

Yes. But they havent yet talked about the performance impact from turning it on.

[Stahlmann]

Also, it's still unclear if any of the current NVIDIA RTX implementations in games like Shadow of the Tomb Raider, Fortnite, Metro Exodus, Battlefield 5, Control, etc. will work with AMD's hardware.

Nobody can, I guess it's because the chemistry between raytracing and games differ from case to case.

That's what I got from the Gamers Nexus vid as well.

 

I'm not expecting the 6000 series cards to outperform team green in RT workloads. Nice to see AMD on top on regular rasterized though.

I'll wait until i see independent reviews before i make any assumptions basen on AMD marketing. But they certainly delivered more than i ever expected thus far.

Yeah, I am deeply impressed also.  Both 6800XT and 6900XT are on par with their respective opponents. 

The good news is that they are much cheaper, US$999 is half that of RTX 3090.  And it does what it is supposed to do.

 

In the likely events that 6000 series raytacing capabilities are not matched with RTX 3000 series, I'll go for a 1080 high refresh rate monitor so I play all games on 1080, just to save some money.  Anyhow, as Tech Deals say, today's top card will be the entry level card in 3 years time/

??? The 3090 is 1500$. Still, it's a great price, but anyone that still needs 24GB of VRAM or CUDA acceleration will still buy the 3090.

To be honest, my last AMD build way decades ago. There were lots of issues.

 

But looking at AMD now, it's like another brand!!

 

When Zen 3 was born, I was actually stunned by the performance. Actually there are youtube video already showing the 5600X vs 10900K.

 

In fact, when Sony first announced PS5 will be using AMD CPU and GPU, one would assume that AMD will reshape the landscape of CPU and GPU popularity. Afterall, consumers  like myself just look at the price/performance factor.

Oh sure, the more VRAM, the faster the rendering will be and more complex textures can be processed and handled.

 

For me that extra $500 can be used on other stuffs like a better luxurious case and a monitor.
