AMD RDNA3 unveiling event

lets not blame it all on user error when the adapters were made to a **** standard, if it looks like its in but didnt click you might assume its fine, my adapter that came with the fe made an audible click and slipped in easily, not all were like that so discarding it as user error lets the corpo off the hook and just makes it sound like the customers are retards

The adapter that came with my Aorus Master 4090 did NOT click. I pushed hard enough to see the connector flex the board and no click.

I know the 12VHPWR adapter is ****, so I took extra care to ensure that it couldn't wiggle out with gentle pressure pulling on the cable so it's fully seated for sure.

However, none of the other connectors in my PC build required such special attention as that adapter.

Yet we have 0.00% of the other connectors on those same adapters melting.

-Funny how the people who can't "plug stuff in properly" managed to plug in the **other** connectors without melting them.

Is that true? What other cards use the new 12 pin?

I'm talking about the adapter itself.

One end is the 12VHPWR connector and then there are 3 to 4 PCIe connectors on the other end of that adapter.

3 to 4 times the opportunity for people who can't "plug stuff in properly" to screw up, yet I have seen 0 reports of the PCIe connectors on the adapters melting.

The other end is a cable to cable connection (so won't be under strain as not mounted and much more visible) and spreads the current load out across multiple connectors.

I don't get how you even make a sensible comparison.

People failing to properly plug in an 8 pin into a card isn't unusual btw. It's a common fix when a card fails to boot.

Spreading the current load is probably the primary reason the 8 pin connectors on the adapters have not melted.

I now have first-hand experience with this adapter and the 12VHPWR connector on my adapter doesn't click and resists being inserted without an amount of force that I would normally recommend against applying to expensive electronic equipment. Its begging for "user error".

Mine was the same btw too, did not click no matter how hard it was pushed. To say all cases is user error is false. Seasonic sent me a proper 12VPWR cable and that does fit in securely and clicks.

Never said it was Nvidias design, just poor as these sort of things need to account for that 1% unfortunately.



As true as that is its irrelevant in this thread but you couldn't help taking a dig at AMD though could you.

My understanding is the issue with the 12VHPWR was that the click was almost inaudible or couldn't be felt with.

It will be interesting to see what AMD's solution to this mess will be.

Not just irrelevant but also isn't true about LGA vs PGA sockets.
Going to LGA for AM5 wasn't about fixing a design flaw around users removing the CPU and damaging pins, that's just a load of nonsense.
The reason they went LGA was to do with higher pin density and power delivery for AM5.

I'm gonna say it.

The RT performance of the 4080 and 7900xtx are as bad or as good as each other.

From what i'm seeing either both can hardly hit 60fps or both exceed 60fps. Sure the 4080 may get 90fps and the 7900xtx gets 60fps or something but they are either both playable or both unplayable, and i don't think either one is anything to shout about. (Looking at the 4k games as that's the monitor I have)

It seems like such a pointless argument on these two cards.

Does it matter if the 4080 is 30% faster in ray tracing at 4k in Witcher 3 than the 7900xtx when it's only getting 35fps, both cards are unplayable.

Does it matter if the 4080 is 15% faster in ray tracing in Riftbreakers if both are 100fps plus?

At 4k at least both cards are garbage at Raytracing and neither card should be bought for on that basis.

I'm a 4k user (though i think ill keep my 1080ti for a while longer) but neither card is suitable for Raytracing in my opinion, they are either both playable or both unplayable in all games. I didn't see one game in particular where one card was playable and the other unplayable. As such looking at the reviews now it seems 7900xtx is a perfect match for the 4080 though it's dissapointing it's not faster overall in raster performance (I got caught up in the hype train)

The annoying part is the 4080 is a bad value card but a better value card than the 7900xtx, looking at the prices Nvidia are sticking to, keeping, and still releasing founders editions so the MRSP of £1200 is sticking around and we have multiple cards available for under £1200. The problem is the 7900xtx was a paper launch, crap supply of MBA cards and as Gibbo said Sapphire will no longer release them going forward, meaning we will only have 7900xtxs available for £1200-£1300.... the issue is even though I think raytracing is garbage on both of those cards it's frankly stupid to buy a 7900xtx over a 4080 at those prices. The "value" is actually in Nvidias favour.

I'm super glad I didn't FOMO and buy one on launch gonna wait until summer I think see what happens with the prices, but my sad little 1080ti will have to continue for a few months more, I simply can't jump in at those prices I was willing to pay £1000+ but to have 0 generational performance increase I don't feel like the 4000 series and the 7000 series are a new generation rather a continuation of the last.

1080ti to a 3080 will be a massive uplift in performance. 4090 is double the 3080 at 4k. Witcher 3 RT version is poor on release but at least free. SOme games still cripple the best cards, particularly with RT on. RT is a nice to have but I think most people still weigh up their buying decisions around pure raster performance. Then there are some technologies you havent experiecned like DLSS. It was good on the 3000 series cards witth DLSS 2 and now 3 on the current gen. FSR works well on the AMD cards. I think you are right not going for either the 4080 or XTX. A 6900XT for £750 (were £650 before xmas) or a 2nd hand 3080 12GB, 3080ti, 3090 or 3090ti will all do 4k comfortably - no card can do RT well in W3, CP 2077 etc, maybe RT set too high or poorly implemented. I wouldn't base 1 games RT perf over a buying decision - understandably this maybe your fave game but the RT implementation is poor currently and Project Red that make both W3 & CP2077 released both games in a buggy state. W3 saving grace is that it's free.

My horror with a 4090 and Elden ring where the game is LOCKED to 60fps! In this day and age! LAst gen top cards will give you a massive boost well in your budget and on most games. RT is a nice to have but it still, in some games, brings any card to it's knees. DLSS does work well with a fettle of IQ.

This is false just Google it, 6 and 8 pin adaptors have melted and caught fire before

A quick google of "pci-e graphics card plug melted" will soon find postings where some have. :eek:

Now see how many melted PCIe connectors you find from the adapters we are discussing.

These adapters have only one 12VHPWR connector and 3 or 4 PCIe adapters. The individuals who "can't plug in a connector" apparently can plug in "a" connector....because they plugged in 3 or 4 of them right around the time they plugged in the 12VHPWR connecor.

The PCIe connectors on my adapter inserts as it should and clicks when fully seated. The 12VHPWR connector? No. It does neither.

Looks like the hotspot issue is exponentially more widespread than Nvidia's 12vhpwr.. what is amd's stance. Do they think it's within spec? Also, is this just limited to the xtx variant?

Well, if it is the vapour chamber then this is going to be the classic f-up of all time. I can't see that AMD can do anything other than recall them all and swap the coolers out.

Maybe they will just swap out the ones that are overheating and stay silent with the rest. We will have to see.

I find it almost unbelievable that AMD have made such a mess of this. NVIDIA must be laughing their heads off. This is the sort of thing that will destroy AMD sales for a long time. All the NVIDIA fanboys will be going on about this for ages!

yeah amd can move on from the drivers are trash thing to the coolers are trash instead, not a great move :P
 
According to DerBauer who tore down the 7900xtx the vapour chamber construction looks fine, but surmises that AMD may not have put enough water in the vapour chamber. Would that explain why the card performs as it should when used vertically ?

On these adapters? With these 4090 owners?

For every 12VHPWR connector that melted there were at least 3 PCIe connectors that were plugged in by the same end user that plugged in the now-melted 12VHPWR.

Searching google for all PCIe connectors since the beginning of time misses the point.

These end users, who are accused of not being able to plug in a connector correctly....just plugged in at least 3 PCIe connectors on the other end of the same damn adapter.
