Radeon RX 7900 GRE Review

Will AMD's suspicious OC bug-fix allow these cards to be potential bargains?
These cards obviously have tons of potential headroom. How much will AMD allow it to be exploited?
Anyways AMD have found a good way to use up 7900 boards without incurring a major loss readying for the introduction of RDNA4.

Memory seems to be the bottleneck for 7900 GRE. So I guess, memory overclocking will be the key here.
 
The Radeon RX 7900 GRE running at the reference clock is +6% higher than a Radeon RX 7800 XT running at the reference clock , the Sapphire Nitro+ then extends this to at least +11%. That's exactly why it's important to test regularly with reference cards (or at least make it clear that you're using factory-overclocked models) . Therefore, the by far most important statement in the video is Hardware Unboxed's commitment to the general representation of purely reference performance:

... what we always do – and that is test GPUs at their base spec using reference or Founder Edition models, when possible, and when not possible, we manually clock them to the base spec or load a base spec BIOS.

This was to be assumed based on previous tests, but has not yet been expressed with this clarity (of course it could have already been mentioned at some point, but who wants to listen to hundreds of videos in their entirety just to find this one sentence) . It would be better if this statement were made clearly in every single video review or written down accordingly in the text versions of the hardware unboxed tests on 'TechSpot' .

A similar approach is currently known from ComputerBase and PC Games Hardware, and TechPowerUp and Quasarzone are apparently taking a similar approach.

KitGuru & Tweakers, on the other hand, test without reclocking, but primarily with reference models (or, in an emergency, only slightly different versions) .

Many other hardware testers, however, still do not know exactly what is being tested - reference model, simulated reference model or factory overclocking.

I just watched Gamer's Nexus review. And a pricetag of $549 makes a huge difference. $649 would have been dumb. So the 7900 GRE slots in between the 7800 XT and the 7900 XT in price and performance.

I just don't know how many people are looking to spend $550 for a middle of the road video card though. The 7900 GRE seems to offer decent value at that price but nothing that screams - I'm a great value, you need to buy me now!

It is what it is. Doesnt beat the 7900 XT and just slightly beats the 7800XT. If you shop specifically for the just over 500, just under 600 price range then this card might make sense, otherwise it's meh.

If you do buy a 7900 GRE, the Nitro+ version is obviously the one to buy though as it has been tuned for better performance than the reference GRE. Still doesn't beat the 7900XT, but shows a bigger performance increase over the 7800XT.
 
A buddy of mine just bought one, inbound this week - he's coming from a 2070 super. Had no intention of spending more than $550. Should be a solid upgrade for those on a 2xxx series.
 
The value this card brings to the table just went up even further.

The hellhound gre I tested had a power target of 290 watts and very easily managed temps quietly. I didn't have time for testing it ocing wise but I'm sure it's fairly modest clocks (~2350mhz) could have made near 2500 or more but efficiency of this gen goes out the window quickly when pushing the core. Would have been interesting to compare to my other two 7900's though.
 
I found this OC guide quite good. He does a great job of explaining all of the options pre-and-post bios update with a great explanation of what really works and what doesn't. It shows that AMD did unlock the super restrictive memory clocks, but not as much as it would seem. No real surprise as they don't want to cannibalize the 7900XT sales.
From the OC review it seems certain cards get higher headroom then others. Could this be older batch 7900GRE's vs. newer 7900GRE's O/C editions more recently produced? Opinions?

PS- WTF did the call it 7900GRE? Would it not have been totally appropriate just to call it the 7900! AMD :rolleyes:

This reddit post pretty much breaks down the performance metrics from 12 review sites. I'd say the 7900GRE is a great contender just from this well established chart.

7900 gre vs 4070:

Overall, the RTX 4070 outperforms the RX 7900 GRE in the ray tracing games by 10–13 percent, while the RX 7900 GRE outperforms the RTX 4070 by 5–17 percent in rasterization-only titles.

There are a few outliers worth mentioning. Borderlands 3 as usual heavily favors AMD GPUs and is a whopping 36% faster on the RX 7900 GRE at 1440p ultra. Borderlands 3 is an AMD-sponsored game, and it has always favored AMD GPUs. The same can also be said of Far Cry 6 (21%), Red Dead Redemption 2 (20%), and Watch Dogs Legion (27%) as well, with only Far Cry 6 being AMD promoted while Watch Dogs Legion was Nvidia promoted.

On the flipped side, Nvidia and the 4070 claim a massive lead in Minecraft, with a 54% lead — and we've seen similar results in other games that use full path tracing, like Cyberpunk 2077 and Alan Wake 2. The latter as an example ran at 52 fps on the 4070 at 1080p with maxed out settings, including Quality mode upscaling, while the 7900 GRE only managed 29 fps (using FSR2 upscaling).

Put a memory OC on that GRE to 2500mhz. Watch that thing become a raster monster. So far on two games I have saw a 20fps increase - RDR2 and Alan Wake 2 at 4k.
 
I just got the RTX 4070 TI Super and my son go this RX 7900 GRE. I am getting 211 fps minimum and bounces to 285fps in MW3 on my intel i9 on highest settings and since my son is installing his card now, I won't get to compare what he is pulling off till later tonight.

That title really favors nvidia from what I’ve seen. There are plenty of benchmarks I’ve seen comparing the two but it will be interesting to hear your take on the two.
 
hello guys, since I got caught by the upgrade, is my corsair tx 650w (old corsair) power supply enough for the rx 6900 gre? I still have a ryzen 5600x, it seems to me that it should be enough?
I also have a 1080p 144hz monitor and a 4k 60hz monitor, for now I'm on 144hz, but with the new graphics I would switch to 4k, would the 5600x be too weak for the rx 7900 gre?
The second choice would then be the rx 7800xt, I think amd is less dependent on the processor than nvidia unless something has changed?
I am curently on rtx 3060 12gb but I'm not satisfied.
 
The 5600x is still plenty for the GRE especially at 4k. The PSU 'should' be fine for the GRE IMO. Toss it in and see how it goes!

I have my 7900xt in my 5600x system right now with a corsair SF600w PSU. No issues running 1080p 165hz on a cheap LG monitor or 4k 60hz on the TV. I do tend to limit FPS at 1080p to 90-120 because personally for what I play its fine and I like the lower power use for better temps. Its an ITX system. At 4k try to play with settings to get 60 frames and its working fine. I can say for me specifically Starfield when uncapped at 1080p the 5600x will spike to 99% CPU utilization and can introduce stutters in that game. Limiting the FPS to 120 or less with Radeon chill and boom the CPU isn't hammered as hard to feed frames and it drops utilization way down and the game is butter smooth. At 4k its GPU limited and the frames are less but they are smooth.
 
maybe someone else with a suggestion and advice? i assume sapphire rx 7800gre pulse ok graphics? here at my place they are around 625 euros, and more, I don't know if the prices will drop further
rtx 4070 super are 680euros and more

Prices will only drop further. Not sure how long you want to wait.

Top RDNA 4 card should have raster of 7900 xt & RT of 7900 xtx / 4070 ti. Price should be in same range as 7900 gre !! (I expect it to be released along with FSR 4. But thats just a guess)

I think I'll wait then, the new amd rx8000 should come out this year, I'm just looking.
It doesn't make sense for me to pay extra money, the price for the gpu alone is higher than the ps5, and I already mistaken up with the rtx 3060 12gb, which I also paid too much for.
 
I'm just looking at the prices in your microcenter, they're mostly MSRP or a little more, and the cheapest sapphire pulse gaming here is 623 euros, if it was close to the MSRP price, I'd buy it right away, but this way it's too much

Here in our country the tax is 25%, I don't even know if the price will fall or maybe even rise
What do you think, should I buy sapphire rx 7900gre for 623 euros or not?

There was a newegg rebate in USA recently.

That gets the price down to $510 for USA residents

Answering your question, German trends indicate that AMD sales have started to fall

They have no other go but to reduce price (or launch RDNA 4, if navi 32 stocks are about to be sold out)

Atleast wait till computex in June, to see future plans of nvidia & AMD

AMD would launch zen 5 in June, but they might also tease RDNA 4 & timeline of the same

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.
