OcUK evening RX7900GRE review thread

[GhostDog1981]

Yeah...

Look at AMD's store, you can buy the RX 7600, RX 7800 XT, RX 7900 XT and RX 7900 XTX directly from them, what's missing are the RX 7600 XT, the RX 7700 XT and RX 7900 GRE, because AMD don't do reference versions of those cards, they are AIB only.

HUB reviewed a card you cannot buy retail, not officially, if you do find one don't buy it because it is not the GRE intended for this market.

And if you do buy the reference pre built only model then it is unlikely to be unlocked?

Nobody knows as nobody on here has got one yet. Maybe a bios flash would sort that, or maybe this allegedly 'oc bug' fix would change things.

Really doesn't make a lot of sense to have 2 cards with the same name but one seems to have a lower power target which is hampering performance vs the global release card.

For anyone on the fence with this card, It seems like a very nice card for the money. Used my Nitro for a few games of BF2042 and played dead space for the last 2 hours. getting solid 120fps on both on ultra at 1440p (I artificially cap the fps to that as I see no point in going higher, so it keeps temps and power usage down).

Biggest problem for me with this card is it's seen general release six months after it launch and, what, maybe ten and a bit months before next gen cards could be getting launched.

True, but looks as RDNA 4 won't be that much more powerful and is a reasonable price in the current market. Well I'm happy anyway.

Ten and something month is a long time to tell anyone wanting to upgrade to wait.

Its long enough for me to tell anyone don't worry whats coming around the corner with next gen, get it now if you think its good value.

Yea and I'm not saying to anyone they should, it's just for me personally I've been waiting something like 3-4 years now for a decently priced GPU so I'm kind of looking at it as why not wait another ten or so months.

In fairness to your point, prices have been over sky high for that amount of time actually.

I think stuff is a bit too high price now but hopefully we are starting to see a creep down in price to make the product tier and performance make more sense.

Read what i said,

I did, you said he used a China only model (that's an AMD reference card from what I can tell) instead of using a global release version (with altered power targets I assume?).

the China only model and the global release ones are not the same card, you still can't buy the reference one outside of china unless you find it in a prebuild like he did, he's pretending they are the same thing but that some AIB models have a higher TDP, no they all have a higher TDP, they are a different card.

What is the "global release" reference card and what are it's power limit? Or has it not been released yet? If AMD choose not to release a reference card in other markets, that's on them. If AMD however have a different reference card for other markets, even if it's not out yet and only annoucned, that's on HUB.

I'd also point out, if AMD have a china reference model gre, and are planning on releasing another, differently spec'd, global spec gre that's also on AMD because that'd be stupid, they should have named it differently.

I see no issue testing a reference model as a base line, testing an aftermarket one with altered specs as a baseline is a no IMHO. It's fine if they're reviewing specific card, i.e. comparing a Nitro+ to an XFX Merc, but not for trying to establish baseline, otherwise which do you put into charts? The slowest one? The fastest one? All of them? Then do you need to do that to all the cards to make it fair?

Starting to wonder if the site advertising the reference MBA card even has in stock what they're advertising after looking at this pic...This is from the GRE listing, yet the backplate says 7900xt. They do list it as an XFX brand card, so maybe their images are wrong. Or maybe they're correct but the text on the backplate never got changed?

Also in this pic.

Might just be stock images

Which doesn't help much if they're advertising something that might look different from what's in the box.

I can see where your coming from but difference being these gpus were not available direct to the public, that's 100% on HUB-the onus is on the reviewer to make sure his previously 'can only be bought in a complete build' gpu is one and the same as an official launched gpu if they want to review the 'new' 79GRE as a standalone 'new' product and not a previously unspecced(in regards to power limits/voltage) gpu bought in a complete build.

Are/were all previous system only gpu's running the same bios as each other, were system builders able to include custom bios for systems to circumvent adding costlier cooling solutions to maintain a certain tdp, there's probably more reasons but that's just off the top of my head.

That's on HUB as a pro reviewer.

In hindsight it's a noob mistake but maybe check first?

If the reference is only available in prebuilts - it's again AMDs problem. I agree that HUB need to make sure that the card spec wise matches any other possible globally or freely available reference model, and if it doesn't they've messed up. If the reference is only ever available in china and in prebuilt pcs, that's AMDs choice, but it's still a reference model. I'm waiting to see if Humbug has a list of specs for a globally available reference.

True, that's a very good point about the BIOS that i didn't think of. I can't remember if they talked about the bios for the reference card, I'd hope they'd check it, and put on an original bios if it has been tampered with. If they haven't that, they messed up.
I suppose they could have taken their other approach, use the sapphire and lower the power limit and clocks to match the reference.

Interesting, so these are 7900xts with some portions of the core disabled. Sorta surprised they never changed the text on the backplate indicating 7900xt. Wonder if it's possible a bios flash could unlock the entire core. Doubt they'd make it that easy, but in the past it has been that easy.

I haven't seen that be common since Polaris (RX550/560), I suspect it is no longer possible

Back in the days of yore I had an x800 pro that I happily unlocked to x800xt-pe spec. Would be nice if it was that simple these days, though I'd imagine the differing vram amounts would screw things up, unless the card still carries the correct amount for 7900xt.

Doubt it would be that easy.

Depends if the MCM package is the one with six MCDs or four MCDs.

Real? GRE model no. is different.
