Very interesting post. The big hope that the Ampere double FP32 pipelines could be used is busted.

And the big assumption that RDNA2 would be a massive uplift over RDNA1 is also disproven in actuality.

Yelp...I could not get one. The search on newegg would not lead to the new cards directly in an effort to thwart scammers' bots.
I will keep trying.

I really want to get rid of these 970's. I am tired of having to turn down the textures and details in games due to the 3.5gb of vram.

Has any RX 6800/6800XT shown up here on MW running the ROCm OpenCL stack?

Is ROCm OpenCL finally working?? It wasn't compatible with most BOINC projects in the past.

I spent a half hour going through the top 200 pages and didn't find one.

I doubt many of the gaming geeks would be crunching numbers like we nerds do so it may be a bit of a wait.
The cards are pretty hard to get ahold of with the current state of supply. I will let you know when/if I get one and we can go from there.

Stock is pretty bad. It looks like 80% of AMD's silicon fab is going to the consoles so GPU's and CPU's will be pretty hard to get for the next month or two.

I also saw news that a good majority of the Ampere silicon got bought by crypto miners directly from Nvidia, so partially explains that product launch unavailability.

That could mean they are very good crunchers too then, orrrr there will be alot of them on Ebay as they switch to something else. :-)

I still think there's value in the old R9 280X.
You can pick one up for about AUD$100.00 possibly lower soon with new cards released. Great credit producer although a bit thirsty.

I see someone has a 6800. (Lucky buggers as they are rare as hens teeth!)

https://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=872217

Unknown how many tasks are being run simultaneously.

I also see it is generating warnings for every completed task. Wonder which part is generating the warning, the driver or the application?

[Edit] Think it is the driver. See wingmen with other AMD gpus and they are also generating the errors.

I sure hope more than one because my 7970 is cranking them out faster running one task at a time @ 55 seconds each compared to theirs @68 seconds each.

I hope so too. But your 7970 has a FP64 rate of 1:4 while the new 6800 cards are only 1:16 FP64 rate.
Your old card may actually be better.

Maybe but speed may come into it and just blow mine away
BTW I have an even older AMD 5870 on the shelf.
