Radeon RX 7900 GRE Review

Sindalis said:
RDNA4 won't have a top end card, highest will be Navi 48. Rumored to be around 7900 XT performance.

More than likely they are going to package this in a "8800 XT" build for around 400-500$

Thus if you need a GPU now, 7900 GRE / XT / XTX are not bad buys. They will be around for awhile and some will have better performance than the top RDNA 4 card at least in raster.

If you don't need a card right now, and/or want to hold out for the latest and greatest, at least you know what's coming.

Personally, I'm finding the 7900 XTX performance being... less than I want. I mean it was a fine upgrade over my 5700 XT, but I'm not keen on skipping another generation. I'm not sure I want to wait another 3ish years for a high end card so I'll have to see what the RTX 5090 offers and potentially look into that for a future upgrade.

They're horrible buys, especially the GRE - a gimped 7900 series because of defective dies. Wow, I just can't even...
 
Rvenger said:
GRE is $550 and put a 200mhz OC on the RAM and it's a monster that rubs elbows with the 7900XT. It's not a bad buy.

Yes, 7900gre is not so bad, only if it were according to MSRP at my place...
Supposedly the powercolor rx 7900 gre hellhound is the best, low heating of gpu and vrm...
 
Yea that hellhound is a nice and cool one. I recently upgraded my nephews rx580 with that gpu and of course I had to test it. Too bad the memory OC driver wasn't available when I installed and tested it.

And, what did you test everything, what are the impressions?
 
Price performance of that card for raster is one of the best in that price range and it does surprisingly well at ray tracing with the extra CU's over the 7800. Never got to test with memory OC unfortunately.

As far as I can tell, most models have vrm chips that allow 20 Gbps effective.
I haven't followed gpu for a long time, but those 7900 gre only recently appeared here at my place, they came out a few months ago as far as I can see.
 
https://www.makeuseof.com/gddr6-vs-gddr6x-vs-gddr7-whats-the-difference/

"However, prolific leaker Kepler suggested on X that AMD's upcoming RDNA 4 architecture (that will power its next GPUs) would still use GDDR6 memory, which would put it at a substantial disadvantage if Nvidia moves from the already more powerful GDDR6X memory to GDDR7.
Now, it's a leak, and is speculative, but Kepler has a long history of accuracy; AMD fans had better hope it is wrong on this occasion, or Team Red will be falling even further behind Team Green."

They could have put at least gddr6x for rdna 4.

This one also says that you should wait for rdna 4, they could turn out to be good and much cheaper.

It should be good & smaller

Nobody knows the price. But we can take a guess

There will be 2 chips

Smaller one (navi 44) = 4060 ti = $300 (or less)

The bigger one (navi 48) should be double the smaller one. That should make it in the range of 7900 xt / 4070 ti super (priced around $550 give or take $50)

In case the launch is delayed to be after nvidia's blackwell, then price should be even cheaper as there is competition from nvidia

Anyway, I don't like it if it's just old gddr6 again.
This one is mentioned above as rtx 4080.
Nvidia only releases rtx 5090?

Nvidia will release a 5090

It is hoped that top RDNA 4 would be equal to (or just short of 4080).

I expect the top RDNA 4 to just beat the raster of 7900 xt & match or better RT of 7900 xtx

The rumour says that all RDNA 4 cards would be gddr6. That makes sense as these are meant to compete with 5070 & below. RDNA will not compete with 5080 or 5090

It seems to me that they have the potential to beat nvidia, but they can't, so they just stay close and that's it.
Because gddr7 is not reserved only for nvidia, anyone has the right to use it, even Intel if they want.
 
Just ordered a 7900GRE as I got it at around the price of the cheapest 7800XT card after a recent price drop. Basically aprox. 500USD list price and 450USD after rebate code, both prices before sales tax. It is one of the more basic models, but should work fine for a secondary rig. Was considering the 4070 super and 4070 ti super, but cheapest regular super was 15% more expensive and cheapest ti super was 50% more expensive. It is for 4k rendering on my sim racing PC so ray tracing was not a consideration as RT at 4k needs a 4080 at a minimum. It should be good for several years in raster only in the games I want to use it for (ACC, F1 etc.). Sure RT would be nice, but feel I would need a high end next gen card to make RT worth it at 4k so decided to just get a good raster card now at a good price.

So which one did you get, can you share which model exactly?
And how much did it cost in the end?
I immediately saw that it is a good card, better than the rtx 4070 super which is too expensive and most of them have very bad cooling and are made at the upper limits of the specifications.
The only drawback of the rx 7900 gre is the slightly higher consumption, most rx 7900 gre cards have adequate cooling.
In my opinion, there is still no real 4K graphics card and the games are poorly optimized for graphics that are still not wow.
In my opinion, GTA6 should be a new benchmark in terms of graphics, but it doesn't have to be. Maybe it will only be based on RDR2, which again has better graphics than many games.

Ordered an Asus dual OC as it was cheap and seemed the have OK build quality. Haven't received the card yet, but it will most likely be here this week. Pricing in USD will vary from day to day due to exchange rate and the rebate code was personal, not a shopping offer for everyone.

I have my pump/res combo mounted at the front so limited to around 31cm max in length without having to go with a slim radiator. No big deal for me if I loose a little bit of performance due to not having a monster cooler and my case is also well vented with air temp sensors on exhaust controlling fans.

The only real 4k cards are the 4090 and to some degree the 4080s.
 
Asus and amd don't really go together, I had an asus dual from amd, it's not something extra great and their software is a disaster.
I would avoid asus and amd, it is best to go with verified amd partners, sapphire, asrock...
Asus favors intel and nvidia.

Software doesn't matter as I never use manufacturer bloatware. E.g. I only use stock drivers and software from either AMD or Nvidia for my GPUs and hate extra stuff from manufacturers like the plague. As long as the build quality is OK then it will be fine. Not like I need a great card for a secondary machine, just needs to be stable card that can run medium load games at 4k at well over 60fps. For my main computer it would be different as that will be a high end card on water when I upgrade it.

I have gainward and I have to admit that their software is not bad, better than msi afterburner.
They have an option for auto oc, the program finds the oc settings by itself and only their program has regulation for led according to temperature, still or rainbow.
The graphics is otherwise hot garbage, it heats up (hot spot almost 90) and the fans spin at over 2000rpm under load.

Hotspot of 90 is not an issue though, if it sits at around a 100 a lot then I would start to worry a little. My 3080 used to be up there when it was on air and it had one of the 2-3 best air coolers. Even on water I get hotspots in the 65-70 range at times, even though overall core temp is generally well below 50 at full 340w load.

Sapphire only offers a 2 year warranty. I have owned 6700 XT and 6600 XT and avoided Sapphire both times ;)

This is from rdr2, the graphics are quite audible, I have a really great cooled case inwin303 but it doesn't help anything.
I tried titanfall 2, I come to that training session, the jumping on the walls annoys me and the game had some strange pauses and stutters, I gave up, I don't feel like playing anything at all after rdr2, the movement is kind of stupid, the graphics are bad.

Rtx 4070 super,the prices started to fall shyly, but rtx 4070 vulgaris not even a cent

Does anyone have an asrock rx7900gre challenger to write a review, not a single review on the whole endless internet as if no one has one

AMD gpu hardware is a failure so far, this gen - and a lot of ppl know it except for fanboys and nvidia haters. The fact that AMD hasn't gone away from gddr6 is so telling. Their cards are not power efficient compared to Nvidia's recent gen, Ada Lovelace and although they caught up in rasterization - it's mostly just barely or slightly ahead - and only with the 4080 which is a card Nvidia crippled and AMD still can't really surpass it - if they do it, it's at the sacrifice of heat and power.

Besides the debate with AMD software - whether the driver situation is improved sufficiently, AMD is lacking in the productivity sphere - with little or no support in many situations or programs - and when there is support, the performance is lacking or behind compared to nvidia gpus/features.

The only reason I even consider an AMD gpu is for Linux and FOSS - if Nvidia and Wayland ever work out their issues - and if explicit sync solves the flickering problems, I don't think I'll need to look at AMD gpus - I'd like to but they seem to put very little resources or investment into their gpus - their main focus is processors/cpus.

ASUS puts the same 'overkill' cooler on their gpus - so, with AMD gpus, that SHOULD be a good thing! I don't think Asus amd gpus will be worse than, for e.g., an Asrock gpu - as Arock only recently got into the gpu game and is an AMD AIB. MSI is dropping out of supporting/distributing AMD gpus - doesn't that tell you anything?

I want to say that amd can beat nvidia in the gpu segment, but that's not allowed, that's the political situation(reason).
No one is preventing them from putting GDDR7, but due to politics, they are not allowed. Nvidia polishes it first(always the first to come out with a new generation), then they (AMD) adjust the performance and prices so that they are somewhere with nvidia gpu, but let's say a bit cheaper.
Such is the situation with the amd rx 7900 gre, in raster stronger than the rtx 4070 super and cheaper(and came later).

7700 XT is faster than 4060 ti
7800 XT is faster than 4070 and can nearly catch a 4070 ti, when overclocked.

7900 XT is faster than 4070 ti
7900 XTX is faster than 4080 and can even beat 4090 in some CPU limited scenarios.

The supers are a reaction to RDNA 3. 7800 XT in particular, sold really well.

Did a 20+ minute stress test and hotspot is fine, temps are good and card is low noise.
temps.png


My case does have size limitations on GPU (about 31 cm) without a rebuild so a 28cm card is also good. There are 2x140mm at the top rear to remove hot air, front top fan location has been blocked off to prevent air recirculation and all dustfilters have been removed for better airflow so fairly good airflow in the case. Fans are also ran on temp sensors for exhaust air temp.

You can say that - many ppl say that. Whether it's true is another story. My point was that nvidia's current gen is more power efficient, has more features (whether you like them or use them is besides the point) and a wider use-case - meaning the performance for each use case is either equivalent or better.

AMD's gpus - the strategy was to be competitive with price and I'd argue that they aren't, really. Some ppl think they are - their similar tiers to Nvidia are much cheaper, supposedly. But, not everywhere and it's not a lot cheaper. For e.g., the 4080 Super and 7900 xtx is around the same price or was. Perhaps, one brand of the 7900 xtx is cheaper (usually, the XFX card). I didn't talk about politics - I only mentioned the AMD gpus not having the 'better tech' in memory - going with an older tech while Nvidia is already at GDD6X and supposedly moving to GDDR7 soon.

AMD gpus also has struggled in sales despite having the 'better price' and 'supposedly beating Nvidia in the gpu segment' - if that is true, why are sales so low (at least, currently)?

I agree, nvidia is more energy efficient, no one can say that's not true, it's also better for things outside of games, they have stronger marketing... obviously both are satisfied and that's it
I like the rx 7900gre, if I managed to sell the rtx 3060 12gb (and I probably won't unless I drop the price a lot) then I would go back to the amd gpu again
RX 7900gre would be good for medium/high settings at 4K.

I hear you. If the 'debate' is strictly about gaming - then, for sure - the argument for AMD is at least, a lot better - and the 'features' in gaming - I've read various debates about that. I was mostly looking at the entire picture or full scope of gpu use - including use outside of games/gaming. :)
