Among the offerings in this series, the Radeon RX 7900 GRE and RX 7900 XT stand out as powerful contenders, each promising a high-end gaming experience. But what sets them apart? Let’s delve into the details in our AMD Radeon RX 7900 GRE vs. RX 7900 XT comparison guide.
AMD Radeon RX 7900 GRE vs. RX 7900 XT: Specs comparison
When examining the AMD Radeon RX 7900 GRE and RX 7900 XT, it’s evident that both graphics cards, built on the advanced RDNA 3.0 architecture and utilizing a 5 nm process size, mark a significant leap in AMD’s GPU offerings. This section delves into the specifics that distinguish these two powerhouse GPUs.
GPU core base clock speeds
The gpu core base clock speeds stand as a critical metric in assessing the raw processing power of a GPU. The RX 7900 XT is designed with higher base clock speeds, enabling it to tackle more calculations per second, a boon for high-end gaming where every frame matters. This higher clock speed suggests that the RX 7900 XT can offer superior performance in rendering complex scenes and maintaining high frame rates.
Conversely, the RX 7900 GRE, while featuring slightly lower base clock speeds, is engineered to provide a balanced blend of performance and power efficiency. This makes it an ideal candidate for users who require a potent GPU capable of handling demanding tasks without significantly driving up power consumption.
Ray tracing refined
RDNA 3 features upgraded ray tracing hardware, promising better performance in games that support this realistic lighting feature. However, benchmark tests are needed to see how big an improvement this is over RDNA 2 cards and how both RX 7900 models compare to Nvidia’s RTX offerings in this area.
Number of shaders
Shaders are pivotal in rendering graphics, as they determine how textures and lighting are processed. The RX 7900 XT boasts a higher number of shaders, allowing it to excel in rendering intricate thorough evaluations of textures and lighting effects, such as volumetric lighting, with more finesse. This abundance of shaders translates to smoother and more realistic graphics, particularly noticeable in AAA titles and professional 3D rendering applications.
The RX 7900 GRE, while having fewer shaders, still delivers commendable performance, adept at handling a wide range of performance differences across various gaming and creative workloads. Its configuration is a testament to AMD’s architectural strategy of optimizing for efficiency without markedly sacrificing visual fidelity.
Dedicated video RAM
Dedicated video RAM (VRAM) is another cornerstone of GPU architecture, affecting how much texture, color, and frames can be stored temporarily for quick access. The RX 7900 XT is equipped with more VRAM, enhancing its ability to perform at higher resolutions without compromising on speed or quality. This additional memory is crucial when running games or applications that utilize large, high-resolution textures or when operating across multiple displays.
In contrast, the RX 7900 GRE’s VRAM allocation, while less than that of the RX 7900 XT, is thoughtfully balanced to meet the needs of most modern applications. This ensures that users experience minimal to no performance dips in standard gaming scenarios and content creation tasks. It represents a calculated compromise between offering ample memory for a broad swath of applications and maintaining cost and power efficiency.
Clock speeds and processing power
The RX 7900 XT takes a lead in the realm of clock speeds, presenting a higher base clock of 1387 MHz and a boost clock of 2394 MHz, compared to the RX 7900 GRE’s base clock of 1287 MHz and boost clock of 2245 MHz.
These differences in clock speeds suggest that the RX 7900 XT might deliver superior performance in average fps, offering smoother gameplay and more responsive experiences in PCs.
Memory configuration and bandwidth
Memory size and bus width are critical for graphics card performance, particularly in handling frames and textures in high-resolution gaming. Here, the RX 7900 XT edges out with 20 GB of memory over the RX 7900 GRE’s 16 GB, coupled with a 320-bit memory bus that facilitates faster data transfers and a higher bandwidth of 800.0 GB/s.
In contrast, the RX 7900 GRE’s 256-bit bus results in 576.0 GB/s bandwidth. These specifications indicate that the RX 7900 XT could better support gaming at higher resolutions and more complex ray tracing scenarios.
Compute units and Shading units
Diving deeper into their capabilities, the RX 7900 XT features 84 compute units and 5376 shading units, slightly surpassing the RX 7900 GRE’s 80 compute units and 5120 shading units. This marginal difference may contribute to an improvement in rendering performance and the handling of ray tracing, essential for creating more immersive and lifelike gaming environments.
Compatibility and power requirements
Both GPUs ensure broad motherboard compatibility and should fit seamlessly into most modern PCs. However, prospective buyers should note the nominal TDP and ensure their power supply compatibility; the RX 7900 XT, with its higher performance, might require a more robust power supply. This is crucial for users considering the golden rabbit edition or other special editions that might have unique power or cooling requirements.

For general web browsing, office software, and lighter tasks, both GPUs will be equal unless your workflow benefits from a particular type of GPU acceleration. For most users, the performance gain in everyday tasks won’t justify the price difference.
Important notes:
- Software matters! Some creative apps are optimized for specific GPUs. Check if your preferred video editor, 3D software, etc., has a preference for AMD or Nvidia cards.
- Consider your entire system: Even a powerful GPU can be bottle necked by a slow CPU, insufficient RAM, or a slow storage drive.
Similar GPU comparisons
To get a complete picture of the competitive landscape, understanding how the RX 7900 GRE and RX 7900 XT compare to both previous generation AMD cards and Nvidia’s offerings is important:
AMD – The Last Generation:
- RX 6800 XT / RX 6900 XT: These cards will likely be significantly outperformed by their RDNA 3 replacements, especially in tasks that benefit from new architectural improvements like better ray tracing. However, falling prices (as is common when new generations arrive) could make these older GPUs good value options if you don’t need the absolute latest tech.
Nvidia – The Main Rival:
- RTX 3080 / RTX 3090: The RX 7900 series is likely to compete around this performance bracket. Independent benchmarks after launch will provide the most accurate picture of where they land compared to these slightly older Nvidia GPUs.
- RTX 40 Series: These newer, more expensive cards (RTX 4080, RTX 4090) are likely a performance tier above. The RX 7900s could offer better value, but might not be able to match the raw fps of Nvidia’s latest.
The Future: Intel Arc’s Evolution:
- Intel’s discrete Arc GPUs are still evolving, and driver updates are improving performance. It’s too early to say if they’ll be direct competitors with the RX 7900 series, but they could be worth keeping an eye on, especially if Intel is aggressive with pricing.
Factors to consider:
- Price: AMD and Nvidia often adjust pricing in response to one another. Fluctuations could shift the value proposition after both RX 7900s’ launch.
- Features: Nvidia’s RTX cards currently hold a slight lead in ray tracing performance (RT) and technologies like DLSS (AI upscaling) for boosting frame rates. AMD is catching up, but this matters if those features are important to you.
- Availability: GPU shortages have been an issue recently. Initial stock levels of the RX 7900 GRE and XT after launch could impact prices and make one easier to find than the other.
