NVIDIA Updates GeForce RTX 4080 Silicon with AD103-301 SKU
NVIDIA has reportedly begun shipping NVIDIA GeForce RTX 4080 graphics cards with a newer GPU SKU that changes the requirement for PCB design and is set to lower manufacturing costs. Previously, the company shipped its AD103-300-A1 SKU to power the GeForce RTX 4080 graphics cards. However, the new AD103-301 SKU will power the upcoming RTX 4080 cards that the company plans to ship to its AIBs and possibly use in the reference design. With the new 301 version, the GPU performance and power envelope should not change. What does change is the PCB design requirements, as the new SKU revision possesses a different chip pinout that doesn't correspond to the old design.
HKEPC has reported that GPUs with AD103-301 SKU are shipping, while VideoCardz confirms the AIB update with Gainward also offering updated cards. GALAX offers RTX 4080 models with either AD103-300/301 as well. Additionally, the GeForce RTX 4070 Ti will also see an SKU update, with AD104-250 being replaced by AD104-251. With these new silicon revisions, customers will not see any difference. However, the AIBs and NVIDIA could see a cost reduction to improve margins. HKEPC estimates around $1 BOM cost reduction with the new SKU, which will make a difference in thousands of cards shipped.

It's not only stores, apparently EVGA got out of the whole business because of disagreements with Nvidia's policy. Hopefully there's a way to make them clean up their act like that. Fingers crossed lower-than-expected sales is a first step towards that.
And when you say "price drop credits", does AMD cover that if some AIB drops their prices? Or only if they lower the GPU prices themselves? Or is that something AIBs do, but Nvidia won't let them?
Have you seen how overengineered their designs are? Here, i'll help
Some of those figures make this seem like a 200W card, not a 450W+ one. There is so much thermal headroom to think of shrinking the RTX 4090 in size. Thanks to the big core surface and vapor chamber designs companies could really go wild, but they don't because they can't. Not yet at least. Designs go through NVIDIA's review before coming out to market. My sources? this is NVIDIA, i'm not going to make a shooting gallery out of my sources. (@TheinsanegamerN)
Not just the RTX 4080 and RTX 4070 Ti can enjoy smaller form factors, so can the RTX 4090. Yes, even with its 450W+ power envelope. Nobody can convince me RTX 4090 cards have to be this large, and a very nice and large table from ours truly confirms it. There are 15, 20, 25 degree Celsius figures here in distance from any remote trouble, not to account the fact most of those fan RPMs barely whisper. The thermal headroom for cooler design shrinking is unreal.
Or maybe you mean freedom in choosing a heatsink. Which AIBs have been done since forever and I have never seen anything about changes in that area.
That said - I am hoping that sales figures of RTX 40 cards will change their minds and let in some flexibility in design, stuff that will allow RTX 4080 cards look more like RTX 4070 Ti cards and not copycats of RTX 4090 cards (which they often very much are, duplicating designs over). RTX 4080\90 cards that are only up to or lower than 3 slots are possible. RTX 4080\90 cards that are shorter than 32cm and only have 2 fans are possible, RTX 4080\90 cards that may have 3 fans but aren't 15cm in height are possible. I'm waiting and hoping to ever see those
But as another random in some forum, I have not one single shred of evidence Nvidia or AMD dictates card sizes.
Now imagine that. RTX 4080 coolers are copycats of RTX 4090 models, and thermal headroom is even larger, much larger. Yet we still got RTX 4080 models identical in form factor to the RTX 4090 cards they are based on. These things truly don't fit in so many cases on the market. The RTX 4080 is one of the first times in doing this whole thing were I legitimately was disappointed by how excessively large these cards are for the amount of power they take. Seeing users having trouble fitting them in many regular ATX cases isn't making this much better.
We used to have options, we used to pick if we want a compact card that might run louder and hotter, just so we can fit it in smaller enclosures. Now our selection in high end GPUs goes from just "very long" at about 32cm to "how will this fit anywhere?!" at over 36cm in some models. Not to speak of the terrible combo of card height with the combination of a power adapter where you get to points even cases like a Meshify 2 won't close on without applying awkward force on the side panel. And all of that for what? for excessively low operating temeperatures on most models, even when the fans barely spin.
When GPUs were simpler, tolerances were higher. Now that GPUs are incredibly complex, tolerances had to be tightened. For example, in the days of Radeon 8500 you were able to choose between 64 or 120MB VRAM. And the smart choice was to go for less VRAM, because that was lower latency. Such liberties in designing video cards are long gone.
And let's not forget transistors got physically smaller and frequencies went way up. That means much more tight voltage and timings control.
Which leads to the question - why didn't they use compact liquid coolers for all FE and AIB cards instead of throwing so much metal at the problem? Are they fighting some type of contracts with the metal producers? And what about the ecology - is it sustainable to waste so much material - so instead of making 5 small cards, they now make 1 large?
One of the problems that now arise from the use of these gigantic cooler designs is that companies like MSI, ASUS and GBT started slightly altering and using them on Radeon cards too, so those now also fit into the monster size category for a lot of models. Thankfully AMD does not force particular form factors and design guidelines on its AIBs.
There is no complete happiness.
Either you choose between:
1. A gigantic GFX which doesn't fit in your case, but even if it fits, could cause a melted PCIe garbage connector which is bent because you can't close the side panel, or;
2. Use a liquid cooler which is much more compact and there is very little chance for something to go wrong.
It is up to you. I choose the second option :D
