AMD Radeon RX 7900 GRE: The RDNA 3 GPU You Can’t Really Buy

Today we’re looking on the new Radeon RX 7900 “GRE” – so not the 7900 XTX or XT – however relatively the GRE. For these unfamiliar with the 7900 GRE, AMD introduced it a few month in the past. The “GRE” stands for “Golden Rabbit Edition,” a brilliant odd title for a gaming graphics card. The title selection stems from the truth that 2023 is the 12 months of the rabbit in Chinese tradition. As we perceive, the 7900 GRE was designed to be unique to the Chinese market, and that is largely nonetheless the case. We’ll elaborate on this.

The Radeon 7900 GRE might be bought as a standalone merchandise, particularly as a DIY part in China. However, in some areas, like Australia, there is a caveat: it is solely accessible in full system builds. So, regardless of having a $650 MSRP, it is not accessible for that worth within the US. One would want to hunt a system integrator that gives it.

In Australia, PLE is the only retailer providing the 7900 GRE. So we went over their web site, configured essentially the most reasonably priced system potential with the GRE, made the acquisition, and awaited its arrival. Our expertise with PLE was seamless. Once the system was prepared, we promptly collected it, raced dwelling, ripped the graphics card out, caught it within the 7800X3D take a look at system and set to work.

Specification-wise, the 7900 GRE is a pared-down 7900 XT, that includes much less of mainly the whole lot. It shares the identical Graphics Compute Die because the XT and XTX variations. Though there are six Memory Cache Dies (MCDs), solely 4 are lively. It additionally homes simply 80 Compute Units, which interprets to five,120 Stream Processors – a 5% discount in comparison with the XT and 17% fewer than the XTX.

The reminiscence subsystem witnesses essentially the most important downgrade. It comes with 16GB of GDDR6 in comparison with 20GB for the XT and 24GB for the XTX. Furthermore, with a 256-bit broad reminiscence bus and 18 Gbps reminiscence pace, you are getting a bandwidth of 576 GB/s – 28% lower than the XT.

While the GRE makes use of the Navi 31 die, its important reductions elevate the query of whether or not it ought to even be a part of the 7900 sequence. The urgent query for us is: How does the Radeon 7900 GRE efficiency examine to the XT? And is it a wise buy in a pre-built system or as a DIY product in China?

1695235277 262 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

Well, let’s go discover out. For testing we’re utilizing our Ryzen 7 7800X3D take a look at system with 32GB of DDR5-6000 reminiscence, utilizing the most recent show drivers. We’ve validated and up to date all knowledge for this evaluation. Later on we are able to current a complete GPU comparability that includes present and previous technology fashions. For now, we have examined the 7900 GRE in 15 video games and can focus on outcomes for half of them earlier than diving into the typical for all 15 video games. Now, let’s dive into the main points…


First up, we have now The Last of Us Part 1. Here, the GRE managed 79 fps at 1440p, making it simply 4% sooner than the 6800 XT. This already makes one marvel why it is thought-about a 7900 sequence class product. It was additionally 5% slower than the 6950 XT, 11% slower than the 4070 Ti, however 8% sooner than the usual 4070. Compared to the 7900 XT, we’re a 20% discount in efficiency, which aligns with the specs.

1695235290 913 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

4K outcomes weren’t extra promising for the GRE. Averaging 58 fps, it struggled to compete with playing cards just like the 4070 Ti and 7900 XT. At this level, it is clear that the 7900 GRE is supposed for these on the lookout for 6800 XT-like efficiency at an identical worth level.

1695235292 248 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

The final recreation we’ll study when it comes to particular person knowledge is A Plague Tale: Requiem. Here, the 7900 GRE achieved 92 fps at 1440p. This made it 5% sooner than the 6800 XT and RTX 3080, and 18% slower than the 7900 XT.

1695235293 709 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

At the 4K decision, it fell behind the 6800 XT and was once more 18% slower than the 7900 XT. However, its efficiency relative to the RTX 4070 Ti was commendable, delivering 17% extra frames than the usual 4070. The efficiency of Nvidia’s 4070 sequence paints the GRE in a extra favorable mild than it’d in any other case deserve.

1695235294 944 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

Now, trying on the 15-game common knowledge at 1440p, the 7900 GRE averaged 113 fps. As we have noticed a number of instances, this locations it on par with the RTX 3080 and 6800 XT when it comes to efficiency, surpassing the 3080 by a mere 5% and the 6800 XT by 8%. It was additionally 11% sooner than the RTX 4070, and primarily based on the urged retail worth, ought to price about 8% extra.

When in comparison with the 7900 XT, we see 19% fewer frames on common, and it trailed the 4070 Ti by 12%.

1695235295 747 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

Increasing the decision to 4K did not carry a lot change. The GRE remained 18% slower than the 7900 XT, 5% sooner than the RTX 3080, and 10% sooner than the 6800 XT. In essence, we’re witnessing an up to date 6800 XT, almost three years later, providing a ten% efficiency enhance. We’ll delve into its potential enhanced energy effectivity shortly.

Cost per Frame (MSRP)

Before diving deeper, we need to deal with the price per body knowledge, beginning with the MSRPs. The humorous factor concerning the 7900 GRE is that it is really by far the perfect worth high-end RDNA 3 GPU AMD has launched, and satirically they have not actually launched it, given you may’t simply go and purchase one exterior of China. Priced at $5.75 per body, it gives barely higher worth than Nvidia’s high worth mid-range to high-end present technology GPU, the RTX 4070, and is 8% higher worth than the 7900 XTX. So, whereas a worth of $650 may not appear spectacular, it will be fairly aggressive in comparison with different choices on this efficiency tier.

1695235297 344 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

Cost per Frame (Retail)

Of course it is the retail pricing that is of most significance to you, so let’s check out the everyday Newegg pricing for these GPUs. Here the 7900 GRE like most present technology GPUs makes little to no sense. While it is definitely higher worth than the 4070 and 4070 Ti, each of which solely include 12GB of VRAM, it merely cannot maintain a candle to the worth of earlier technology components just like the 6800 XT.

1695235298 80 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

The GRE is at the moment 14% extra expensive per body than the 6800 XT, so even should you might purchase it, you’d seemingly be higher off shopping for the older RDNA 2 GPU on the present discounted worth of $530. Alternatively, the 7900 XT might be had for $750 and at that worth it is also higher worth than the GRE, you additionally get 20 GB of VRAM which in all probability is not all that vital, but it surely’s a pleasant bonus for a product that is already higher worth.

In brief, if the GRE have been accessible within the DIY market, its worth level would have to be not more than $600 to be aggressive with the $750 XT fashions and, after all, the outgoing 6800 XTs.

Power Consumption

1695235299 888 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

When in comparison with the outgoing 6800 XT, the large benefit of the 7900 GRE is energy effectivity, although it is in all probability not an enormous total issue. In Hitman 3 we noticed complete system consumption lowered by virtually 70 watts, a 15% energy saving, in order that’s good.

1695235301 576 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

However, in Spider-Man Remastered, we famous solely a ten% saving, amounting to round a 40-watt discount. This means that the 7900 GRE will not all the time be considerably extra power-efficient than the 6800 XT, however total, it is undeniably the extra environment friendly of the 2.

The Reference Model

It’s our understanding that solely AMD reference model of the GRE can be accessible, and that is definitely the case for now. Also, solely AMD and unique companions resembling XFX, Sapphire and PowerColoration can be promoting the GRE.

In phrases of design, the GRE reference mannequin seems virtually equivalent to the 7900 XT reference mannequin, although there are some key variations. The GRE backplate measures 267mm lengthy and 96mm broad, whereas the XT backplate is 276mm lengthy and 99mm broad. The coolers are additionally very totally different, the GRE cooler weighs 737 grams whereas the XT cooler is 46% heavier at 1078 grams. Meaning, the XT is a barely larger and far heavier product.

1695235302 167 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

Over on the PCB, the GRE options 2 fewer energy phases, and naturally, there are two lacking GDDR6 chips which scale back the capability from 20 GB to 16 GB. As far as energy enter, it nonetheless makes use of two 8-pin PCIe connectors after which for I/O we discover the very same configuration.

1695235303 80 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

The solely different noteworthy distinction is the GPU itself. The GCD and MCD format and dimensions are the identical because the XT and XTX fashions, however as we famous earlier, two of the six MCDs are disabled.

But what’s actually attention-grabbing is the package deal, the place the XT sits on a 54mm x 47mm package deal, the GRE makes use of a a lot smaller one at 40mm x 39mm. This is probably going the design we’ll see the Radeon 7800 XT undertake and with fewer lively reminiscence controllers we assume that is how AMD has been capable of shrink the package deal.


Here’s a fast have a look at the working clock speeds and temperatures of the 7900 GRE reference card. After an hour of load we noticed a peak hotspot temperature of 89c and a junction temperature of 75c.

1695235305 68 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

The peak temperature is not superb although a fan pace of slightly below 1400 RPM in all fairness low and the cardboard was definitely very quiet. The cores sometimes clocked at 1940 MHz, so about what we noticed from the 7900 XT reference mannequin and as anticipated the reminiscence operated 18 Gbps. So total respectable outcomes, however not almost nearly as good as lots of the customized AIB 7900 XT’s.

What We Learned

Overall, the Radeon RX 7900 GRE is an uncommon product. We would not label it as unhealthy, however you could be higher off avoiding it, on condition that discounted 7900 XT’s supply better worth. Alternatively, the Radeon 6800 XT supplies almost the identical efficiency degree at a significantly lower cost.

In the PLE system we bought, the 7900 GRE is priced at $1,100 AUD. Although PLE is not at the moment promoting the 6800 XT, PC Case Gear is, with a tag of simply $850 AUD. Based on our knowledge, which means in Australian {dollars}, the 7900 GRE prices $9.73 per body, whereas the 6800 XT is priced at a mere $8.09 per body. Consequently, the GRE comes with a 20% premium – fairly steep.

1695235306 716 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

Furthermore, it is possible to amass a 7900 XT for as little as $1,170 in Australia, making it solely 6% pricier than the GRE. With a value per body of $8.41, one would naturally lean in direction of the 7900 XT when contemplating a current-generation GPU. However, in Australia, it is advisable to scout round for these 7900 XT offers.

While there’s inventory accessible for the $1,170 fashions, each PC Case Gear and PLE have priced their 7900 XT’s nearer to $1,300. Even at this charge, you are analyzing a value per body of $9.35, which stays lower than that of the GRE.

1695235308 476 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

As we have talked about, the 7900 GRE is an atypical product, and we’re ambivalent about it. We’re not eager on AMD’s selective sampling to reviewers and imagine it is in poor style to launch a product with a reputation so intently resembling current merchandise. It’s perplexing that this mannequin is categorized below the 7900 sequence when it is 20% much less highly effective than the 7900 XT, which is a trimmed model of the XTX, and it additionally possesses 20% much less reminiscence than the XT.

A extra becoming designation would have been the 7800 GRE, or higher but, the Radeon RX 7800 XT, with wider availability. Nonetheless, we anticipate the launch of a product named the 7800 XT subsequent month. It’ll be intriguing to gauge its efficiency relative to the 7900 GRE, and naturally, its pricing.

1695235309 29 AMD Radeon RX 7900 GRE The RDNA 3 GPU You

For now, our recommendation is to strategy methods that includes the 7900 GRE with warning. Ensure you examine costs, because the 7900 XT and even 6800 XT might give you extra worth. This wraps up our preliminary evaluation of the 7900 GRE, however count on new cell and desktop Radeons making it to the worldwide market within the coming weeks and months.
