The GPU rumor mill is churning at full speed, and this time, it's AMD's next-generation RDNA 5 architecture that's taking center stage. A fresh leak from a noted hardware insider has painted a tantalizing picture of what we can expect from Team Red's future mid-range contender, codenamed "AT3." If the specifications hold any water, AMD could be preparing to redefine the performance expectations for the mainstream gaming market.
According to the leak, the heart of this new GPU will boast 48 Compute Units (CUs). For those keeping score at home, that translates to 3,072 stream processors—a significant jump in raw shader power compared to current generation mid-range offerings. But the real headline-grabber is the memory subsystem: the "AT3" is allegedly outfitted with a 384-bit memory bus.
This is a monumental shift. A bus this wide is traditionally reserved for flagship, halo products—the kind of graphics cards that command a premium price and are built for 4K ultra-gaming and high-resolution content creation. To see it potentially trickle down to a mid-range chip suggests AMD is taking a radically aggressive approach with its RDNA 5 strategy.
Why a 384-Bit Bus is a Big Deal
For the uninitiated, the memory bus width is a critical determinant of a GPU's memory bandwidth—the speed at which the card can read and write data to its VRAM. Think of it like a highway: a wider bus has more lanes, allowing for more data to flow through simultaneously without traffic jams.
A 384-bit bus, when paired with next-gen GDDR7 memory (which is all but guaranteed), would provide staggering bandwidth. Even with conservative memory clock speeds, we could easily be looking at over 1 TB/s of bandwidth. This massive throughput is essential for feeding the hungry stream processors with data, especially at higher resolutions like 1440p and 4K, where high-resolution textures and complex scenes can bottleneck even powerful GPUs.
This move signals that AMD is aiming to eliminate memory bandwidth as a limiting factor entirely, allowing its RDNA 5 architecture to stretch its legs and maximize performance per watt.
Contextualizing the Leak: A New King of the Mid-Range?
To understand the potential impact, let's compare these leaked specs to current and last-gen cards.
- AMD's current RX 7700 XT features 54 CUs but on a narrower 192-bit bus.
- The previous-gen RX 6700 XT had 40 CUs on a 192-bit bus.
- NVIDIA's RTX 4070 (non-Super) utilizes a 192-bit bus.
While the CU count on the "AT3" is slightly lower than the RX 7700 XT, the colossal leap in memory bandwidth could easily allow it to outperform its predecessor by a significant margin, potentially challenging competitors in a higher price bracket. This spec points to a card designed for flawless 1440p gaming and confident 4K performance.

The RDNA 5 Promise: More Than Just Specs
While the "AT3" leak is exciting, it's important to remember that raw specifications are only part of the story. The RDNA 5 architecture itself is expected to bring major improvements in efficiency, ray tracing performance, and AI acceleration. AMD has been playing catch-up in ray tracing, and RDNA 5 is widely anticipated to be the generation where they close the gap substantially.
Combining a more efficient and powerful architecture with a no-compromise memory subsystem like a 384-bit bus could create a perfect storm of price-to-performance value.

A Word of Caution: The Nature of Leaks
As with all pre-release information, it's crucial to treat this leak with a healthy degree of skepticism. Specifications can change dramatically during the development and prototyping process. What we see today might be a best-case scenario, an early prototype, or even a complete fabrication.
However, the source has a credible track record, and the strategy makes sense from a competitive standpoint. With NVIDIA's next-generation Blackwell GPUs also on the horizon, AMD needs to come out swinging with compelling products at every price point.
What This Means for Gamers
If these leaks prove accurate, the future of mid-range gaming looks incredibly bright. Gamers could be getting what is essentially flagship-level memory technology at a much more accessible price point. This would put pressure on all players in the GPU market to increase their offerings, ultimately leading to better value and more innovation for consumers.
While we wait for official announcements from AMD, the anticipation is certainly building. The battle for the best graphics card is about to get a lot more interesting.
Looking for a powerful GPU today while you wait for next-gen? The current generation of graphics cards still offers fantastic performance for modern games. You can find great deals on last-gen models to tide you over.
