New AMD Radeon 6000 Series, Has Nvidia finally been dethroned?


Recommended Posts

The AMD Radeon RX 6000 Series represents the forefront of extreme engineering and design, delivering ultra-high frame rates and serious levels of 4K resolution gaming. Powerful new compute units, and the all new AMD Infinity Cache along with up to 16GB of dedicated GDDR6 memory, enables the ultimate gaming experience.

So, this above is the official blurb. What do you guys think, and how will this impact DCS World (if at all?) especially in VR?

Specially in VR.... Hmmmm.... Difficult question to answer.

Many reviews will come just to compare on flat screen. (And there is the next Vulkan thing too)..... Developers were strugling with AMD Vulkan drivers in the past, but things may be different now?

Too many doubts right now.

But Nvidia is in trouble in the future because AMD will be executing on 5 nm at fall 2021 and Nvidia could be behind that timeframe (maybe).

AMD will be using a DP 2.0 or 1.4 as Nvidia 3000 series?

What about Ray tracing performance?, and what about de equivalent AMD DLSS 2.1 for VR?

Foveated rendering?.... (One thing for sure: right now the Nvidia drivers are more optimized for VR than the ones at AMD. And maybe they are one year ahead in that departament).

Availavility? (That may be a vital factor).

And when things starts to clarify a bit starting next year we may have Intel too..... O_O

TSMC fabs won´t be enought to keep up with so many wafers.

The wilderness await us.

There is also the pricing to consider, the 6800TX and 6900XT are significantly cheaper than their Nvidia counterparts, with only the "regular" 6800 card being more expensive than the RTX 3700. I'm disappointed that the midrange card on offer is more expensive than the 3700.

Also, what I see is the 6000 series has 16Gb RAM while 3080 series from has 10Go and DCS can suck up to 11-12 Go VRAM at high resolution (like VR). That and the direct access memory stuff they talked about improving the stutter reduction when on a Ryzen 5000 series platform... AMD is now on par with NVidia on the perf side, with 300W TDP (NV 3080 is 320W TDP). So yeah, I'll definitely consider a 6800XT + Ryzen 5800x or 5900x as an upgrade (from Core i5 6600k @ 4,3GHz + GTX1080 @ stock)... I just wait the 3rd party benches now (yes, I know the other games does not reflects the perfs in DCS because the programming architecture is totally different, but it's still an indication).

Is DLSS something DCS can take advantage from?

 

I don't think so. Maybe at some point in the future if they do another major engine overhaul, but if that happens it is still a long way off.

AMD does not support DLSS (NVidia proprietary) but they talked about 'Super resolution'. It's still unclear what exactly it is or how it will be implemented. As for the RayTracing, they do not follow the RT-core approach from NVidia but are working on API level through DX12 Ultimate.

Currently DCS does not support neither DLSS nor RT.

I'm very interested in seeing which way this goes, but I think the key tests will be when reviewers start bench marking FS2020 with these.

 

My initial guess is that it will do a bit better than the 3080 in Dx11 games, and if you are running less than 4k resolution. I'm thinking it will also depend heavily on how good Zen 3 turns out to be for VR, as one of the big performance boosters is the smart memory access, but that is only available on Zen 3 CPUs. If Zen 3 cannon-balls it out of the park in Dx11 VR, then the Radeon 6K's should be very nice, but if we come out of it with the 10900K at 5.3+ still being the king of Dx11 VR, things may lean nVidia.

 

Another open question is what nVidia will do in responce. There are rumors that they are considering bringing out a 3080 TI grade part, with 11 or 12 of the memory controllers enabled. That could bring 3090 grade performance at the $1000 price point.

 

In raytracing, from what I'm hearing about compatibility issues, I'm not sure it's going to be a factor for another year or so, but I could be wrong. It will depend on what we see in the actual launch reviews.

 

Overall, it's going to be very interesting winter...

What I really do not like is the 256-bit memory bus. That is less than the 352-bit of a 1080ti. We will see if the infinity cache is dealing with the small memory bus as good as promised.

 

I use in VR up to 300% supersampling (slow Anton over the channel map, low fps anyways, high ss no harm) with good results on my 1080ti & G1 (3832x3744 pixels). I am curious how the 6800xt will cope with such special use cases in VR.

As a 1080T! 11GB user, it is the card I want to upgrade from, so I compared the specs between my EVGA GTX 1080 Ti SC2 and the RX 6800...

 

Radeon RX 6800 will launch for $579 and go toe-to-toe with Nvidia's RTX 3070

Thanks, at least the bandwidth is higher on the 6800XT than on the 1080TI inspite of the smaller bus interface. I am looking forward to the first VR (or 8k as a performance hint) benchmarks. 6800XT 512 GB/s is not a big improvement over the 1080Ti 484.4 GB/s. I only want to use very high (>=8k) resolutions in use cases where I am already limited by the CPU, so probably the bandwith will not interfere.

 

I am only interested in Nvidias alternative offerings when they manage to get the actual power draw into 300 Watt regions.

 

Who ships wins by the way :-)

 

(The distance between the 6900XT and 6800XT looks bigger in the amd charts because of the test settings than the real performance difference)

I'm very interested in the 6800xt , but have a lot of questions . Driver history , tessalation performance (surely important in DCS ?) and the overall lack of DCS performance reviews with RDNA 1 are all kinda scary issues to a Nvidia user .

I have the feeling it's going to take a while to make an informed decision , but my 1070 is barely holding its own with my RiftS , and the G2 has to wait on a gpu , so the sooner the better !

(edit) Just read Aurelious' post regarding 6900xt . Wow .

Those are the figures for the RX 6800 since I'm aiming at mid-range rather than the top end, for the XT see AMD website.

Yes, don't confuse the RX 6800 with the RX 6800XT there is quite a bit of a performance difference between them.

No confusion here ;-)

 

6800XT Memory Interface 256-bit Memory Bandwidth Up to 512 GB/s

 

Memory buses and bandwidth are similar, this is not where the XT makes the difference, all 6800 uses the same 16 GB GDDR6 and 128 MB Infinity Cache, so does the 6900XT.

 

In my case I will be more than happy with the 6800, considering that I will probably have to upgrade CPU (Ryzen 5000 after a BIOS upgrade for my B450) and memory as well (DDR4-3600), it will help keep the cost low, especially because I will be able to keep my actual 750w PSU, while providing with substantial increase in performances at 4K.

Before considering splashing dosh in any of those cards, make sure your motherboard buses supports them as well as the CPU and RAM you'll need to get a good bound out of them, there is no point spending your money and end up with a 15% bottleneck...

I dont believe in bottlenecks, I am an agnostic. I believe in settings ;-)

 

You're mistaking religion with technical reality.

 

Any specialist will tell you that to get the best of your system you need the best bound possible between GPU, CPU and RAM, settings won't always solve those issues, it they did, there would be no reason for techies to mention bounding and bottleneck in the first place.

 

Setting are good for fine tuning, but useless for compensating for a weak CPU or GPU, checking proper bounding before buying solve the problem.

We will not agree and look at all those violence in religious dissens, so no need to decide our differing views :-)

 

I am perfectly fine at choosing my own bottlenecks to my liking. The bottlenecks available to me with my hardware I am totally aware of :-)

 

And if all fails I adjust my body :-)
