AMD silently nerfing the performance of older GCN cards

GCN1.0 is a 4.5 year old architecture. The only customers i have any pity for is the fools who bought a R9 370 and R7 360. However said fools should have bought a GTX 950 or 750Ti, as those cards were clearly faster in 9/10 tests and still is. 

There is a reason, no need to assume. AMD Has stated that the driver team is looking into it.

 

Doesn't matter, you are assuming that people are smart, no-one is. everyone just fakes it till they make it (and as you get older you'll realise everyone is fucking brain dead, including yourself). Purchasing a r9 370 or 360 was fine, stop putting your personal opinion into the mix, they could have gotten a better deal, where locked into a specific system and the gpu was acceptable, got it on sale, is cheaper where they live, etc etc. many reasons to pick a 370/60 over a 950/750ti.

actually, you're quite wrong in many areas.

A: AMD is typically notably more expensive outside of EU and North America then Nvidia is.

B: if no-one is smart, and we are all idiots. Then microprocessors must be made by aliens. That or you are just trying to throw a ad-hominem without being too personal, thus trying to dodge the Community Guidelines.

C: -snip-.

D: -snip-

E: There were never "many reasons" to pick the 370/360. There was one -> Brand Loyalty.

 

The same way there were only one reason to buy a GTX 980 after Fury linup launched. Brand Loyalty.

Async compute under dx11 hasn't been touched (and never was by anyone, don't thing a single dev even looked at it) GCN 1.0 was dx11 (wasn't even sold as dx12). This feature that was promised at time of purchase is still enabled. dx12 Async, which wasn't promised at time of purchase as added on later.

Driver support hasn't been dropped.

Didn't say it was. I was replying to a different poster explaining the difference between this and dropping driver support.

 

After advertising a feature (even post release) users should be notified if it is disabled.

Would you say it is NOT OK, to disable a feature for a very small family of GPUs, if the execution of said feature is holding back development of said feature globally?

 

I dont. If there has been a underlying change to DX12 AS/AC execution in order to improve global performance, and said change is not playing ball with older GCN cards, then fuck it. Disable it for those cards until you can fix it, or dont fix it.

This should be a last resort if it needs to be done for the good of the industry and moving things forward.

And in that scenario it needs to be clearly mentioned in the driver release notes. Not wait until users discover something isn't working and ask AMD for comment....

Biggest AMD fanboy on LTT here.

 

AMD was wrong to turn it off without telling customers regardless of what the bugs were.

[LukaH]

i have no idea what the current word here is i just skimmed the first page but....

 

on the pcper live podcast regarding AMD ReLive they mention it was by accident and are looking into it. not sure if this was mentioned in this topic yet but here you go.

From what I understood there is 1 game where it was shut down/ doesn't work anymore and in every other game that worked it still works. What's the problem then ?

From what I've read, it's all games. Tomb Raider and Ashes of the Singularity are two games that have been tested, as well as some benchmark.

A: kewl story bro, mind pointing out some examples? we know this isn't the case due to MSRRP. AMD's cards are typically cheaper when compared with the same 'class' of card. 

B: being a dumb shit doesn't mean you can specialise at not being a dumb shit in one very specific area. No seriously, you and me we both moth breathers, just because you know ad-hominem doesn't make you smart, also if you look at the context of what I said, you'll find it actually wasn't' Ad-hominem at all. because I wasn't directly insulting the person I replied to, I was saying in general people are stupid. Which if you want evidence, look at president trump.

C&D: ? what?

E: This is one of the basic concepts of economic theory, the well informed customer will make a perfect purchasing decision. Brand loyalty is just one of the reasons products that are objectively better for the same cost are not purchased. I already provided a couple of others, and if a consumer doesn't have perfect market knowledge, such as being swayed by marketing material, there you go plenty of reasons.

 

Another might have been availability, takes a few month for a card to show up in enough numbers to meet demand. If I am on holidays for 1 week, I don't want to get my card 3 weeks later, i'll just go get what is in stock.

 

Sorry but this is ad-hominem: your critical thinking skills are shit. And ban-hammer incoming in 3..2..1...

No sure, they shouldn't have disabled it silently, I agree, but saying they don't have the right to disable it in future drivers is big difference.

 

Keep in mind that all GCN1.0 cards would have been EOL (not end of support) when dx12 was released, so all these feature where added as a benefit after the consumer had decided to get the cards.

Issue fixed in Crimson 17.2.1.

[Humbug]

Well done AMD on fixing it.

 

Next time just mentioning what is going on in the driver release notes will prevent stories from flying around.

 

Glad to see that GCN 1.0 is still getting stellar support after all these years.
