AMD RDNA4 Information...Pre/Post Launch

[67Elco]

This just came up... https://www.newegg.com/Product/ComboDealDetails?ItemList=Combo.4765175 and this... https://www.newegg.com/Product/ComboDealDetails?ItemList=Combo.4764727 Yeah, I want you guys just as broke as I am. There are still GB cards with bundles up. Interesting how Newegg kind of filtered stock in throughout the day...it's almost like they are acknowledging the fact that scalpers made off with the bulk of the initial release...or they are just scalping us themselves by combining these cards in bundles with some of their overstocked items. Also got a email from CentralComputers saying they are having a raffle for their next shipment of 9070 XT's...they made it clear it is a all out effort to stop the scalpers and they have a decent plan in place.

Still plenty of cards at Newegg, but only available in bundles.

I got sniped scalped , couple hours late Newegg is outta stock

Undervolted RX 9070 XT beats RTX 5080 — RX 9070 and 9070 XT models with heavy coolers have massive OC headroom

Multiple online tests affirm the power of AMD's undervolting curve

Somehow, it suggests that the power limit is too low for "standard" cards. Once the voltage is lowered and a higher power limit is set, the cards boost higher and perform better. On the other hand, I guess that AMD wanted to keep them at an acceptable wattage and match the general GPU specs.
It's about the same as with AMD CPUs - lowering the voltage causes them to boost/overclock higher.

AMD has said in the past they have to set voltages to ensure everything they ship works stable. Average might do better, but they have to plan for the worst they're willing to sell. Otherwise you end up with the old Intel CPU thing where you have a bunch of similar models differing by 100 MHz. Maybe AIBs do that binning, and assign better chips for higher end OC models.

In Der8auer's vid, it was funny just watching him lower the voltage and the bins go up without even touching the power limit. Weird to see when something isn't temperature limited already.

This is because lower voltage = lower wattage (that you know ), and these cards run at the power limit (literally few W below) ... so lowering the voltage gives frequency boost more headroom.

Everyone has done that for years, not only AMD. Look how Nvidia keeps the same voltage for generations in different GPUs. It's somehow logical, as who would care about 10% higher performance when the RMA rate will be 10% higher (just an example, not exact numbers ). I feel that AMD is aware of high wattage if power limits are unlocked, and they also know that the efficiency of these new GPUs is not really better than the last generation.
Like you said, it's hard to guarantee that all CPUs/GPUs run the same at the same voltages, so all pick the worst case scenario and add a few % on top of that. What AIBs do is their problem, but AMD somehow forces some specs (I'm not sure if they have the same partner agreements as Nvidia, but Nvidia makes everyone stick to some specs).

I only mentioned it because I vaguely remember it was a big noise for one of the past releases, although I forget exactly which one. It was the hot thing of the time so AMD had to make a statement on it.

 

[Woomack]

There were many cases of too high "hot spot" temperature in the RX7000 series cards and too loud cooling. I guess that to reduce possible problems, AMD set safe voltages and a lower "stock" power limit. At 330W+, these cards still can't be cool and quiet (also depends on what quiet means for some people).

AMD fans never mention issues. If Nvidia or Intel has issues, the web is flooded by haters. AMD cards are cheaper than Nvidia cards (not so much in most stores if we compare the assumed performance shelf by AMD), but people just try to buy them, not complaining much. When Nvidia cards were released, we could see everywhere how big a failure they were. People were buying and complaining about everything.

Lol, I know. It's been a couple of years since I handled an amd card, so, again, just funny to see it live/in action. Nvidia doesn't behave that way in most cases (there's headroom and it boosts to the 'max' out of the box). But that's enough mansplaining things we already know, lol!

It would be good to see how high it scales with high power limits and maybe temps, too, since frequency boost can be improved by both (and some other things). I have no idea what limits are set for the boost in these cards.

Some AMD fans also shouted that 16GB is not enough. Somehow, AMD has released only 16GB cards so far, designed for 4K (at least marketing says that). I wonder if we see anything higher in the upcoming months, as comparing 9700XT to 7900XTX in specs only, most things are worse in the new series (still performs better).

 

[EarthDog]

From der8aur's vid (and TPUs overclocking), you don't seem to get much from raising the power limit. It scales hundreds of MHz without even touching it.

Purchased a 9070 xt from eBay. Almost $400 more than the exciting competitive price of $599

 

[Woomack]

As I see, it costs $1k+ unless you buy it from MC or in a combo deal. Amazon has some offers for $1.1k+. In Poland, cards sell well, and new deliveries are made every day (available models change daily). Still, prices in regular online stores are about $900-950 inc. 23% VAT, so could be worse.

I'd rather have bought a combo and got a PSU..........to keep or sell. You just paid more for nada.

 

[unsafesteagle]

@EarthDog I thought the same until sometime between midnight and 5 a.m. stock was sold out again

Had to make the target time wise delays n all.

This 1 is the xfx quicksilver haven't bought xfx in over a decade , so
I believe that's 2 x 8 pin power pcie

Reviews and photos on the web say it's 2x8 pin. Considering the latest news about undervolting, this should be more than enough to get some more performance out of it.

Congrats on the new card. Which model did you get?

Edit, super slow to update. XFX Quicksilver. Mag Air fans?
