The Sapphire Radeon RX 7900 GRE is a good graphics card for gaming at 1440p with plenty of performance headroom for a few years. It does better than the RX 6800 XT from the previous generation and goes toe-to-toe with the RTX 4070 Super. We don’t have the official Indian pricing for the 7900 GRE but we did spot some listings for INR 70,500 which seems a little higher considering that the RTX 4070 Super, which is as good in raster gaming and better in ray tracing-enabled gaming, costs INR 63,000. To be cost-effective, that’s the max that this card should sell for to be a great 1440p gaming graphics card.
An exclusive to the Mainland China market until now, the AMD Radeon RX 7900 GRE (Golden Rabbit Edition) is a slightly scaled down version of the 7900 made to celebrate the year of the Rabbit – 2023. Well, it’s no longer the year of the rabbit and the card is no longer an exclusive as AMD has now launched it globally. There is no vanilla Radeon RX 7900 so the GRE isn’t a new term that AMD is going to be using across the stack like the XT or XTX suffixes that it has. For all intents and purposes, think of this as the RX 7900 that should have launched along with the other top-end cards.
The AMD Radeon RX 7900 GRE serves as the middle ground between the RX 7800 XT and the RX 7900 XT. And you might be wondering why AMD is releasing a card that has already been released? Well, since NVIDIA has been rather busy padding its roster with cheaper cards, it was only natural for AMD to also put a few cards out. Which also begs the question, is this too little and too late? Let’s find out.
AMD Radeon RX 7900 GRE Specifications
The AMD Radeon RX 7900 GRE is based on the Navi 31 GPU which is the same that powers the Radeon RX 7900 XTX and the XT. The only difference is the number of active Dual Compute Units within the Shader Engines. Navi 31 has a total of six Shader Engines which can host up to 6144 Shaders and the GPU that sits on the 7900 GRE is a slightly cut down version of that. We don’t know if it has five or six active Shader Engines since the 40 Dual Compute Units can fit in either configuration. The 7900 GRE has a total of 80 Compute Units or 5120 Shaders which churn out 45.98 TFLOPs of performance at peak clock speeds. And since each Compute Unit hosts one Ray Tracing core, we have a total of 80 Ray Tracing cores. The other components such as the Render Output Units (ROP) and Texture Units are proportional i.e. 192 and 320, respectively.

Coming to the memory configuration, the AMD Radeon RX 7900 GRE has a similar configuration as the RX 7800 XT. So it has 16 GB of GDDR6 memory chips connected to a 256-bit wide memory bus. The memory clock is at 2250 MHz which is a bit lower than the RX 7800 XT. So peak memory data rate is 18 GBps as opposed to the 19.5 GBps bandwidth available on the 7800 XT. And the clock speeds are also a little lower at 2245 MHz boost clock as opposed to the 2438 MHz that the 7800 XT is at. More shader cores running at higher clock speeds can often consume a lot of power so this is absolutely normal. Until you see the clock speeds on the 7900 XT or XTX which are clocked at 2394 MHz and 2499 MHz despite having way higher shader cores.
Essentially, the AMD Radeon RX 7900 GRE has fewer cores which ideally could have been clocked higher but hasn’t been. And it has slower memory than all the cards in its vicinity which is also a step back. All of this leads to about 40 Watts of power savings, if at all that was the end goal. It seems like there is a lot of potential in this card that cannot be leveraged or will not be leveraged. All of that is totally fine if this is priced right and performs competitively. So, let’s see how it fares in that department.

It leverages DirectX 12 to assess how well a GPU renders the game’s detailed vehicles, realistic environments, and advanced lighting effects. This benchmark specifically provides insights into the graphics card’s efficiency in delivering high-fidelity visuals and smooth performance in a competitive racing context, highlighting both traditional rendering and cutting-edge ray tracing techniques.
The Witcher 3: Wild Hunt
The Witcher 3: Wild Hunt, an expansive open-world RPG set in a gritty fantasy universe built on REDengine 3, does not officially include a built-in benchmark tool for testing graphics card performance. Typically, performance assessments focus on rasterization, as the original release predates widespread ray tracing adoption. The benchmark run follows a custom path cutting across several game scenes to evaluate GPU performance. We run the benchmark in DirectX 11 mode for a legacy comparison metric across generations of GPUs.

Far Cry 6, a first-person shooter set in the fictional Caribbean dictatorship of Yara, includes a built-in benchmark that tests graphics card performance focusing on both rasterization and ray tracing capabilities. Utilizing the DirectX 12 API, it evaluates how well a GPU renders the game’s lush landscapes, complex physics, and detailed character models. This benchmark thoroughly assesses a graphics card’s ability to deliver high-fidelity visuals and advanced lighting effects in a rich, open-world environment.
Compared to the RX 6800 XT, the 7900 GRE is a minor improvement over the 6800 XT. We did not have a 7800 XT to compare the card against, so we can’t tell you how much of a performance difference there exists between them. We have the scores for the 7900 XTX, which is about 43 per cent ahead in synthetic benchmarks. And compared to the 6800 XT, it is about 22 per cent ahead. In gaming, the 7900 GRE is about 4.5-5 per cent ahead of the 6800 XT. And compared to the recently launched RTX 40-series Super cards, the AMD Radeon RX 7900 GRE goes toe-to-toe with the RTX 4070 Super but is usually lagging behind by a few FPS with ray tracing turned on. Without ray tracing, the 7900 GRE is the one ahead. But in the grand scheme of things with both raster and ray tracing performance considered, the 4070 Super gets a slight advantage.
Verdict – Radeon RX 7900 GRE
The Sapphire Radeon RX 7900 GRE is a good graphics card for gaming at 1440p with plenty of performance headroom for a few years. It does better than the RX 6800 XT from the previous generation and goes toe-to-toe with the RTX 4070 Super. We don’t have the official Indian pricing for the 7900 GRE but we did spot some listings for INR 70,500 which seems a little higher considering that the RTX 4070 Super, which is as good in raster gaming and better in ray tracing-enabled gaming, costs INR 63,000. To be cost-effective, that’s the max that this card should sell for to be a great 1440p gaming graphics card.
