The stock 6800xt gets 8873 in port royal and the overclocked 6800xt gets over 9000. Yet the review shows over 9000 in port royal as stock. CPU does not affect PR at all, its all GPU. SAM does not affect it as well. Only overclocking.

This is the normal stock 6800xt in Port Royal. https://www.guru3d.com/articles_pages/amd_radeon_rx_6800_xt_review,27.html

then 9143 points. https://arstechnica.com/gaming/2020...view-the-1440p-gpu-beasts-youve-been-craving/
rx-6800-series.018-980x735.jpeg

is it overclocking? yes. see here. https://www.overclock3d.net/reviews/gpu_displays/amd_radeon_rx_6800_and_rx_6800_xt_review/20

So overclocking the 6800xt to 2.4GHz gets you 9116 points. https://www.overclock3d.net/reviews/gpu_displays/amd_radeon_rx_6800_and_rx_6800_xt_review/5
This last benchmark confirms stock at 8934.

So some reviews likely have special 6800xt's so be careful.

Its a bit faster than a 2080TI in RT, the 3080 is 29% faster than the 6080XT.

Its AMD's first go at RT, Nvidia's second, if 78% RT performance is unplayable? Then 100% RT performance is barely playable.

I don't understand this huge put down for AMD's RT performance, apart from a couple of outliers that probably need fixing on AMD's GPU's given its a week old architecture thier RT performance is not much worse than Nvidia's, its a little better than Nvidia's previous generation and Nvidia have oly moved it up 30%, is it really so bad?

The AMD card is faster at 1440P and 1080P without RT, it uses less power, its cheaper and it has a lot more VRam which makes it the better card IMO, you have a choice between that and 30% better RT performance. its all good. no need to try and knock AMD down, what's that all about?

It's very interesting how the Nvidia image has no water splashes once the car is in the water:

Look at the trees, there is defiantly more LOD culling on the 3080, more shader rendering on the left image, and yes, where are the water splashes on the Nvidia side?

Should have gone to Specsavers. They are at two different locations on the track. On the 3080 side the car hasn't even reached the water. No idea what's going on with the 3080 here, but the game has numerous bugs hence the poor Steam reviews.

Second image its clearly in the water.

@4K8KW10 where is the video?

3080 side (right) second tree in from the right is the 1st tree on the AMD side. That alone cleary highlights that the Nvidia car has not reached the water yet.

That's untrue - the Nvidia car "never reaches" the water - there are never water splashes on the right screen. Watch the video.
 
Being pedantic here but I'd like to give some input on the Dirt 5 water thing.

If you actually watch the video at the part screenshotted the AMD had a jump into the water and he took a different line wih the Nvidia which meant he never left the ground so water wasn't as apparent.

To confirm there isn't anything weird going on go to 5:21 in the video in which the Nvidia also got a jump as his line changed.

Downloaded the video, played it in slow motion and you can clearly see water splashes just as the video starts to break up. The car appears to enter the water at a different location and angle. The presenter even mentions this being a problem and why it shouldn't be used as a benchmark :rolleyes:

NVIDIA drivers usually circumvent game code. To give some sort of image quality advantage. In this case it broke the games image quality instead of helping them. Which is why you see that anomaly. In my opinion.

now I understand why you're so easily marketable. In your reply its apparent it would take somebody to say, "yes I did..blah blah blah" before posting the difference between right and wrong.

All this commotion over some water splashes

Both the sun shafts / ambient occlusion and the water splashes are resource intense, so when you cut them, you effectively increase the frame rate.
