RX 7900 GRE

From some reports its a China only release, what I would strange in the link you gave, its all in English as if you could buy it.

If it does release outside of the UK, money on its OEM only like Lenevo or Dell.

I am also putting a theory this was the GPU that AMD tried to prepare in advance for the new Mac pro but Apple said they won't be using anyone elses GPU anymore.
 
I posted the same question in the 7800 XT thread, it looks like DIY in China, but OEM worldwide (THG have an article that it is available in a pre-build in Germany). AMD have given it a USD price though, so who knows.

Wouldn't be surprised if they were salvaged chips given it is still Navi 31. So might not have many.

7900 XTX salvage chips would drop to 7900 XT. Then the worst to 7900 GRE.

They all have 57.7bn transistors.

The true 7800 XT will be a different chip.

Does this suggest it is not being binned, if accurate? I don't know how the packaging relates to the dies in that process.

We compared the sizes of the new "Navi 31" package found in the RX 7900 GRE, with those of the regular "Navi 31" powering the RX 7900 XT/XTX, the previous-generation "Navi 21" powering the RX 6900 XT, and the NVIDIA AD103 silicon powering the desktop GeForce RTX 4080. There are some interesting findings. The new smaller "Navi 31" package is visibly smaller than the one powering the RX 7900 XT/XTX. It is a square package, compared to the larger rectangular one, and has a significantly thinner metal reinforcement brace. What's interesting is that the 5 nm GCD is still surrounded by six 6 nm MCDs. We don't know if they've disabled two of the six MCDs, or whether they're dummies. AMD uses dummy chiplets as structural reinforcement in some of its EPYC server processors. The dummies spread some of the mounting pressure applied by the IHS or cooling solution, so the logic behind surrounding the GCD with six of these MCDs could be the same.

They should have measured the size of the MCDs and GCDs. That would have actually have helped.

They look near identical in the photos.

I doubt AMD went to the effort of designing another chip that is almost identical to the Navi 31 chiplets.

They need different ones for more SKUs. My guess is that the GCD is a salvage chip and not suitable for a 7900XT or XTX.

Will this card be released on the UK? I'm seeing it mooted as the successor to the 6800XT and would be interested in opinions on that. :)

The 7900 GRE is a total joke, its gonna be about 13% faster at best than a 6800XT, and yet the 7800XT is going to be even slower than this. Well done AMD, literally zero gains in 2.5 years and a new node and architecture.

The reason?, because they got greedy and wanted to copy Nvidia and move cards up a tier/rename them so they can charge more. For this reason alone I wont bother with AMD, if both AMD and Nvidia are going to be douche bags and greedy, I might as well have the better brand of card....

If the 7900XT had come out at $700 day one, Id have given AMD a shot, after having only had Nvidia for 15 years since my last AMD card. But they just do not want new customers it seems.

So they named this this 7900GRE and people are saying this is about 15% faster than a 6800XT which puts it within 10% of a 3080 10GB that came out nearly three years ago that launched during the pandemic/mining boom and cost at the time $50 more.

At $649 there is no point in doing a DIY launch here

Who's gonna pay $649 for 10% faster than 6800xt. When you can get a 7900xt for $699 which is 35% faster than 6800xt

Wonder what GRE stands for? :confused:

Apparently, GRE = "Golden Rabbit Edition".

Suspect that because the launch was in Shanghai (China), and the marketing and advertising wanted to entice the Chinese market, they tried to give it a "suitable" name for the product. But unfortunately, whoever advised them didn't advise them well enough.

Also suspected, that the Rabbit, is taken from 2023 (Year of Rabbit). The Golden part however, is just the superstition of the Chinese wordplay where they dislike anything that sounds "unlucky" or "unfortunate". Given the Year of 2023 is a "Water Rabbit" in terms of the sexagenary cycle the old Chinese system uses, and therefore NOT Gold, Golden or anything related to Golden aspect. It is suspected that because the normal adjective for the Water element in Chinese is dark, flowing, black, encompassing, mysterious, etc, none of which sounds good for a card really whilst advertising it, they defaulted to the "Everything is Gold/Golden", even when it's not supposed to be. Rabbit would be Wood for example, and the Water on top being Water, clearly would using their own system would have nothing to do with Gold/Metal at all. But it is (superstitiously) considered by Chinese that Gold/Golden is the luckiest (It's not).

So overall, suspected that it's to help try and push sales by ego stroking the Chinese market.

They've done something similar in the past for Apple which there is a new Mac Pro but doesn't work with GPUs anymore.

So it's likely AMD got blindsided or hopefull thinking.

NV don't want to retain their high end customers.

I've been 10 yrs NV exclusive, went 3080>79XTX as the 16Gb 4080@>£200 more expensive than the 24Gb XTX, so it seems AMD gained one new customer.:p

The problem with both companies this gen is that you cannot get an upgrade over the last generation without spending more unless you already spend over £1000
