AMD Confirms Ray Tracing Graphics Cards!

6 months or so ago I read an article about the next gen play station, a developer saying that people will be in for a big surprise. I took that to be a nod for RT.
 
Sheesh, This fella & his clickbait titles, How he manages to talk so much while saying so little amazes me, My first introduction to him was his pre Turing's announcement video where he was all excited, saying something along the lines of "I've got it, I've got the exclusive scoop from my sources, I can 100% confirm that the new gpu range will be called the GTX 1100 series", Not a good start. :D

I find this guy very annoying.
 
Meh. I would rather they concentrate on normal performance first,since the moment ray tracing will be introduced it will be an excuse to further jack up pricing. AMD could also do with improving performance per watt - raytracing won't help them gain marketshare with OEMs if they find it hard to get into prebuilt desktops and laptops. All they are doing is trying to compete with Nvidia on the high end,whilst failing miserably in the mainstream,and for most people all they see is Nvidia everywhere in these mainstream systems which is free advertising.

ATI even with the HD3000 series against the Nvidia 8000 series had a higher percentage of sales than AMD does.
 
One solution for the performance hit of ray tracing might be the return of accelerator cards specifically for ray tracing just like what we had for 3D graphics back in the mid 90's?

To be fair, RT looks amazing. Its the price which makes me not care about it.

Well if AMD don't improve performance per watt,then its not going to help them even with RT. RT can be done via dedicated units,or AMD simply adding more shaders. Either of these means larger chips and more transistors,etc which increases power consumption. So if AMD does not improve the performance per watt of their base uarch its not going to help them be competitive.
 
AMD GPU power consumption is not really any worse once you undervolt them (and you should because it can get you a noticeable performance boost). It's old news.

Plus value isn't even on the scale with the current nvidia cards :/

AMD has hardly any exposure in OEM laptops and desktops which are sensitive to performance per watt for power supply and cooling reasons,and you can see at the high end they are still not able to compete properly. They had to wait until 7NM to have a GTX1080TI competitor.

ATI had far more exposure in this regard,ie,the HD3000 series marketshare was better than what AMD has now,and that is with the fastest ATI single GPU card being slower than the 4th fastest Nvidia card,ie,the 8800GT.

The fact is you could argue Nvidia designs could be undervolted too - the thing is are still needing more memory bandwidth to do the same job as Nvidia,which alone is not helping with power consumption,let alone die size.

They really need to improve in this regard,if not Nvidia will keep pushing forward. Big Vega still has a ton of stuff not working properly from what I gather including tile based rasterisation which one area where Nvidia is ahead,and that does help with improved bandwidth utilisation and power consumption.

These also directly impact their APUs too BTW.

To not have this working 5 years after Nvidia did something similar is a joke. None of us expected this would be the case after the GTX750TI launched.

Have you noticed they cannot scale past 64CUs or even 64 ROPs?? They have hit a uarch brick wall right there.

Instead of chasing RT unicorns,they really need to fix the issues with their current uarch first,otherwise Nvidia will still outsell them,and if Intel actually has something competitive,then that is even more competition.

I would rather they let Nvidia have RT for the next year,if they fix the scaling issues they have past 64CUs,improve their memory bandwidth utilisation,etc.

Start with a properly refreshed uarch and then add in RT makes far more sense,than stick with something which is hitting its own set of uarch issues then add RT to it.

Theres loads of Ryzen laptops. In fact they are the best choice atm. AMD's APU are pretty good.

Nvidia cards don't undervolt nearly as well as the voltage and clock speeds are directly linked in their BIOS. If you turn the voltage down, the clocks will drop too.

Almost every tech source with their "exclusive scoop" was wrong with the Turing line up hah. So many of them claiming it would be Volta as well.

The issue is almost all of the dGPU laptops are Nvidia. AMD is not competitive. Look for AMD laptops with dGPUs in the RX470/RX570 class. You can count them on one hand.

AMD cannot even get tile based rasterisation working 5 years after the GTX750TI debuted. Its a feature of Vega which doesn't seem to be functional. This is why AMD needs to use HBM2 which costs so much,since it draws less power,and requires less die space for the memory controller. Nvidia can get away with using cheaper memory technologies like GDDR5,etc even with the penalty of a larger controller.

They really need to stop chasing RT unicorns and get these basic features working in the hardware,and get some of the other features they advertised two years ago working in this years GPUs. The 64 CU limit is becoming a liability - its another reason why they have issues at the top end - GCN is not designed for high clockspeeds at reasonable power consumption levels,ie,why they need to push voltage in the first place. This is because they cannot move past the 64 CU unit so clocks are one of the areas they can push performance.

RT ATM is just a pointless distraction for AMD. Concentrate on improving the uarch scaling,performance per watt,memory bandwidth utilisation,etc and that will give AMD more sales,then probably a stop-gap RT hack on their current uarch,which Nvidia will be probably run better anyway currently.
