You have to prove there is something wrong. It does not matter what happened and when it happened in the past. Each argument must be considered on its own merits. The only standard is if an argument meets burden of proof.

RT performance for example does not benefit much from overclocking. The rest is a good question, next week the AIO 6800xt's come out so this could change. No they cant reach 2.65GHz easy, most reviews hit 2.4-2.5GHz under load. The fastest air cooled 6800xt on HWBOT has a 2.65GHz boost but the clock speed is much lower under load because of the power limit. They also hit 90c+ at 2.4GHz. If we overclock the 6800xt you get 4% more performance.

Time Spy. 6800xt OC 18304 The card was stable with 2500 or 2600MHz dialled in, but actual frequency diminished slightly as I pushed passed 2400MHz. https://www.kitguru.net/components/graphic-cards/dominic-moass/amd-rx-6800-xt-review/32/ 10900k 5.1GHz



Time Spy RTX 3080 factory OC 1935MHz 8700k 5GHz (The RTX 3080 hits a lot higher than this on a good card, with water reaching up to 2.2GHz) score 18306 https://www.tweaktown.com/reviews/9...-3080-oc-edition/index.html#Test-System-Specs

Couple things I want to add and agree with

you're correct that OC'ing doesn't add much performance to the gpu - seeing 5% extra performance from the overclocked reference cards. High clocks? Maybe, big increase in performance? Doesn't seem likely

Also the clocks in 3D Mark don't tell the full picture, these cards we've seen with claimed "2.6ghz" that just the maximum and it can't hold it for long, gamers nexus review showed the max boost got held for a few seconds and then tanked. The average clock speed from people sticking air conditioners over their pc which is what actually matters is 2.3-2.4ghz it will be interesting to see how much higher they can get with cards that aren't capped with the reference tdp, I belive we're going to see some AIB 6800xt with other 400w power draw so hopefully those can get closer to holding 2.6ghz for long than 3 seconds

The question will be more easy to answer once the custom cards become available. Its why I pick the factory overclocked RTX 3080, I wanted to give a more reasonable overclock to compare to the 6800xt. A completely overclocked 3080 water cooled and modded for no power limit (pulling 650watts) will give a 3090 FE a run for its money. Somehow it does not seem fair. A water cooled 3080 at nearly 2.2GHz constant has a decent performance increase. Air cooled some people get into the 2100MHz and above with boosting. These are custom cards with high 450 watt power limits and a custom 6800xt wont be out for awhile.

The RTX 3080 has a 8700k 5GHz which is much slower than the 10900k @ 5.1GHz all cores that the 6800xt has. The performance increases show that both cards once overclocked can get more or less close to one another in DX12. The overclocked RTX 3080 can match blows with an overclocked 6800xt. Thats all I wanted to show.

A shunt modded 6800xt on LN2 cooling has appeared in firestrike, scoring just under the 3090. The card had a maximum clock speed of 2.75ghz

There was a leaked slide where ms thanked NV for sharing it's dlss model. The model can be implemented in different ways though.

What we do know is that red team’s DLSS alternative is being developed in cooperation with Microsoft and can be applied to any game, which gives it a big advantage over NVIDIA’s offering.

Through their collaboration with AMD when creating their new consoles, AMD has a chance to replace DLSS with an alternative which will apply to gamers on both PC and Xbox, giving developers little reason to support DLSS over DirectML Super Resolution.

Through close collaboration and partnership between Xbox and AMD, not only have we delivered on this promise, we have gone even further introducing additional next-generation innovation such as hardware accelerated Machine Learning capabilities for better NPC intelligence, more lifelike animation, and improved visual quality via techniques such as ML powered super resolution.

Just for the record, people tend to completely ignore that interactive ("real time") viewport rendering, when they talk about the history of ray tracing. Viewport rendering has been around for a long time. I think Octane renderer was the first and that had a semi public release prior to 2012 (it might have been invite only). Often the viewport used streamlined algorithms to improve render speeds.

Viewport rendering allowed people to move objects in viewport, move the camera through the scene and change material properties and visible objects. While watching it update in real time.

Here is a demonstration video from 2013. Starts at 42 seconds.

TensorFlow is an source library that helps you with developing and training ML models. I don't think its is the same as giving MS DLSS. DLSS is more the final product after you have done the developing and training. Getting from one to the other is not an easy task.

That argument doesn't make a lot of sense. Dlss is a mathematical model that can be deployed anywhere with relative ease

You have to train a nerual network for it to work. You create a model then you have to train it. The training part is important, without training your model you can't reach the level of accuracy you need and the level of optimisation. At the start DLSS worked only on a per game basis. So you take your model and train it to get the best results for a given game. This is a far cry from the general model that is DLSS 2. It would take a lot of proccessing power to train the model and significant amounts of time. Once the model is trained, then you can start deploying it.

Being handed the starting model can get you started but the real work is improving and training the model. Then you have to work hard to get a model that can be deployed to work in real time. The tensorflow model NVidia provided did not work in real time. So there was lots of work to do.

3DMark - Fire Strike overclocking records @ HWBOT

"With the overclock, the GPU was able to score an overall score of 48,890 points and 61,831 graphics points in the 3DMark Fire Strike benchmark. This makes the Radeon RX 6800 XT not only the fastest GPU on the planet but also the only GPU to have broken the 60K barrier in 3DMark Fire Strike. If we compare it with the previous entry, you can see a 4% performance uplift in performance with a 150 MHz higher boost clock.

We can expect the Radeon RX 6900 XT to reign supreme in the HWBot Hall of Fame once it launches next month but for now, even the Radeon RX 6800 XT is a force to be reckoned with, offering insane overclocking potential with a very compelling price versus its competitor & even NVIDIA's flagship RTX 3090 graphics card."

That is what I thought when I saw his post :p

He seems to get this pleasure from posting stuff about nvidia being better. Lol.

Lol. Learned a new word. Thank you. There are quite a few here from each side :p

Readings this thread some here seem to think you are one of them. Are you a wing nut sir? Or just a nut nut? :D

Don’t be fooled people. This user went and bought a 3090... Get him!! :p
