The RX 7900 GRE as of 20/03/2024 - Not such a flawed product?
- Thread starter g67575
- Start date
General Relativity Edition. It warps the perceptions of the Chinese market 
I found a review that looks at overclocking the card, here:
hardwareand-co.translate.goog
Minimum clocks are around 2000Mhz. With overclocking + unlocked power limit, an extra 200-300 Mhz seems to be achievable. Overclocking the memory seems to be artificially limited.
The GPU voltage seems to hit around 0.83v when overclocked, which doesn't seem that good. Temps can reach 88 Celsius also .
Lower quality GPU dies, maybe?

Beats the majority of cards at a better price point
Not sure how one would reason to call it pointless.
Buddy got one and he is happy with it.

If they rebranded GRE to RX 7900 or RX 7900 LE with SKU's between £580 to £620 would work. Still to much money but so is the whole GPU market.

I think the issue is that the spec isn't quite good enough, with some parts actually worse than the RX 7800 XT.
It has the same CU count as the top cards from the last generation, e.g. RX 6900 XT, but the performance can sometimes be worse.
So, unfortunately it's not worth much more than the RX 7800 XT - it looks like AMD was just making use of the weaker GPU dies that didn't make the grade for RX 7900 XTs.
Most would be better off with an RTX 4070 Super (priced at ~£540 currently) if spending over £500, which would be consistently ahead of GPUs like the RX 7800 XT.
You might still get a RX 7900 GRE if you need the extra 4GB of VRAM...
There's a clear gap in the market at ~£600, but no card that fits the bill.

AMD Radeon RX 7900 GRE Coming To US With Big Price Cut
The Radeon RX 7900 GRE should retail for $549 and will compete with Nvidia's RTX 4070 and RTX 4070 Super.
www.google.com
So it's supposodly going down to $550 in the u.s. which is about the only price point that would make this card even worth considering, as its only fractionally faster than the card currently masquerading as the 7800xt.

Meh. People get to caught up too much on naming schemes /branding.
The RX 7800 XT is essentially a successor to the RX 6800 because both have 60 Compute units.
The RX 7900 GRE is sort of a successor to the RX 6900 XT (both 80 CUs), but a flawed one unfortunately. The spec needs beefing up, but I imagine AMD is worried about it performing too much like the RX 7900 XT if it had the same GPU and memory clocks.
It looks like boost clocks of 2400 MHz should be possible (with higher memory clock speeds as well), which makes me wonder why an upgraded version hasn't been revealed yet, and priced at ~£600. Maybe AMD never produced enough Navi31 dies in general.

The 7900 GRE is 5% faster than the 7800 XT, if that, because the board power is exactly the same, 260 watts vs 263 watts, there is no place for it to slot in to, AMD idiotic new naming Scheme is in this case not the problem, they are essentially slotting in a 16GB card where one of their own already exists and trying to charge $50 more for it, the same performance.
Clock it up a bit, give it a 280 watt board power and 19.5 Gb/s memory IC's to put it between the 7800 XT and 7900XT, charge $550 for it and bring the 7900 XT down to $650.
There is no point in dropping the 7900 GRE as is, no one is going to pay $50 more for something with the same 16GB and +3% performance over the 7800 XT.
Edit: and call it the RX 7900 or RX 7800 XTX, drop the GRE thing....

It was a way of them using defective 7900 chips and cutting cost of vram/other components that would otherwise go in to a 7900XT at a higher cost.
There isn’t really a place for the GRE except next year there might be some juicy discounts to get rid of stock prior to release of RX 8000

But but but it’s for the ladies.
The RX 7900 GRE is getting a global release on 27th Feb 2024:

It's targeted at the RTX 4070, at the same price, and is unsurprisingly faster in just about every game, according to AMD.
Still, it seems like a missed opportunity, there's basically nothing competing with the RTX 4070 Super, which was previously priced at £540 (but is costs a bit more currently for the cheapest Zotac model).
Presumably, the specs are set in stone now, as they have been listed here since the initial limited launch in July 2023:
https://www.amd.com/en/products/graphics/amd-radeon-rx-7900-gre
So, that limits it to:

- 'Up to 18 Gbps' for the memory speed

An overclocked 7800xt gains around 12% over stock and match’s the 7900 GRE at stock. Rather pay less and overclock tbh.The RX 7900 GRE is getting a global release on 27th Feb 2024:

Gains around 5% I believe once overclocked and the limiting factor is the power limit. Vram speeds are gimped vs 7900xt’s bandwidth.

They might refresh the 7800xt and release a 7850XT which would be reflecting a “7900” slotting in and replacing the GRE.
