GIGABYTE Intros Radeon RX 7900 GRE Gaming OC, European Availability Expected

[btarunr]

GIGABYTE is ready with its first custom design graphics card based on the AMD Radeon RX 7900 GRE (Golden Rabbit Edition). Originally designed for the Chinese domestic market, the RX 7900 GRE is finding its way across other Asian markets, and is also available in Europe. This GIGABYTE graphics card could be among the RX 7900 GRE cards to make it to the old continent. The card's design resembles that of the company's RX 7800 XT Gaming OC, which is slightly smaller than that of the RX 7900 XT Gaming OC. It features a triple-slot WindForce 3X cooling solution with a dual aluminium fin-stack heatsink that uses a copper base-plate, four heatpipes, and a trio of 80 mm fans. The card is about 30 cm long, 13 cm tall, and 5.6 cm thick. It uses a pair of 8-pin PCIe power connectors.

The Radeon RX 7900 GRE is based on the "Navi 31" XL silicon, which is essentially the "Navi 31" chiplet GPU on a compact package that's about the size of a "Navi 32." AMD designed this smaller package for its mobile RX 7900 series SKUs. The RX 7900 GRE is configured with 80 RDNA3 compute units, which make up 5,120 stream processors, 160 AI accelerators, 80 Ray accelerators, and 320 TMUs. It gets the full 192 ROP count of the silicon. The SKU only has four out of six MCDs (memory cache dies) enabled, which gives it 64 MB of Infinity Cache, and a 256-bit wide memory bus, driving 16 GB of 18 Gbps GDDR6 for 576 GB/s of memory bandwidth. The total board power (TBP) of the RX 7900 GRE is configured at 260 W, which is about the same as that of the RX 7800 XT. The GIGABYTE Gaming OC card is expected to come with a slight factory overclock for the GPU.

At least the PCB doesn't seem to be the "Gigabyte's suicidal PCIe PCB crack edition", but the fixed one.

It's a shame how restricted this card is. I get that it could potentially perform to close to 7900XT with the same core and memory clock, but having a card with 33% more shader perform only slightly better than 7800XT because of restricted TDP and slow memory is just a waste.

What's the reason for these cracks?
From a mechanical point of view, it is impossible to crack even that small a PCB, if it has a metal backplate attached to it, which will distribute the heavy load of the cooler on it.

Some Gigabyte cards where "saving" like a square or two centimeters of PCB with the result being easier to crack. Gigabyte realized the problem (translation: they where getting negative criticism online) and fixed that.

If they really want to *save*, they must undervolt and put smaller coolers with lower weight and less bulky. Instead of cutting a few inches of each unfortunate PCB.
Otherwise, we will begin to suspect that intellectually disabled people cut these PCBs.

Nice to see - must say I havent recommended Gigabyte cards recently to builders.

On a nother note - in Denmark we have seen a lot of these "China" only market cards and I wonder if the sale of the Year of the Golden Rabit Edition have been so week in China that they simply have made to many of them. There isnt any good reason for a 7900 lite edition in the product stack with the recent low end AMD cards so it seems poor market management to release these cards in EU and US.

In Denmark the cards is about 10% more expensive then the 7800XT but often comes with the reference 7900XTX/XT cooler - wonder if theres a refurbish use of the RMA coolers from the XTX line?

I would avoid Gigabyte altogheter. Had 7900XTX Gaming OC from them, after 5 months due to pump out or some other issue hotspot temp was reaching 110C.
I mean I saw a lot of cards had that issue, but their warranty is just a joke. I did RMA through shop that I bought it in, and not only was their service not replying to me, that's understandable, but also not replying from shop itself.
Got to a point that even a seller gave up and just refunded my card.

No its not a waste its exactly the opposite if you udnerstand anything from chip manufacturing

all nvidia gaming gpus are wastes from the ai segment they sell you the literall trash that they cant sell for a 5 figure

another nothingburger just like the nvidia power adapter.

Again with this. It's quite impossible AMD has so many NAVI31-GPU that are this crappy that the card couldn't perform much better. 80SM isn't much worse than 84SM on 7900XT and clock could be much higher without any difficulty and without coming to close to 7900XT.
I don't get AMDs angle here, either. Had they given 20Gbps memomry and slightly more TDP and core clock to the 7900GRE, the card would fit neatly between 7800XT and 7900XT. The way it is now, either 7800XT or 7900GRE is superfluous, depending on price.

it was a china oem model. its not impossible but we will nebvver know for sure so its worthless talking about it.

Specwise, the 7900GRE seems to be very close to the 7900XT.
What's the issue then? (if the tdp and clocks can be manually adjusted?)

@gffermari : Somehow, it performs only slightly better than 7800XT, probably because of the same TDP. Even increasing TDP to the maximum +15% (~300W) doesn't do much. At stock TDP the core clock is about 400MHz lower than 7800XT and ~350MHz lower than 7900XT. OCing doesn't change much, as the 7900GRE gains about 100MHz, the 7800XT slightly more, the 7900XT slightly less. Both 7800XT and 7900GRE are still capped by TDP sometimes.

It's a phenomenon I often see in modern GPU. TDP = performance, at least to a degree. An otherwise identical card with less shaders will perform about the same as another card with more shader by using the TDP-headroom for higher clocks. You can see that with NVs new Super cards, too, since 4080S and 4070TiS clock slightly lower than their predecessors with the same TDP. Thus, 4080S is not even 5% faster than 4080. Of course, much more shaders or other improvements (wider memory bus and more memory in case of 4070TiS) lead to performance gains, but nowhere near as big as the difference in shader count. Plus, since about Pascal, all GPUs of the same generation seem to have about the same clock limit, given enough TDP.
