It is rumoured that AMD’s upcoming RDNA4-based graphics cards, unofficially being called the Radeon RX 8000 Series GPUs, will be sticking to the GDDR6 memory running at 18Gbps. It’s a sign or sorts, that AMD maybe shelving its plans for its Navi 4x GPUs, potentially leaving its customers and Radeon fans without a beefier replacement for its current top-tier RX 7900 models.
The rumour comes by way of popular leakster Kepler (@Kepler_L2), who says that all RDNA4-based cards will be running on the slower GDDR6 memory. This is despite the industry being expected to move on to GDDR7 memory at the end of the year, which is also expected to run at speeds upwards of 28Gbps. For the uninitiated, AMD’s current Radeon RX 7000 Series lineup use the 18Gbps speeds, which is also the maximum speed used by the top-tier models too.
Only 18Gbps 🤔

In contrast, NVIDIA’s upcoming GeForce RTX 50 Series is rumoured to run on said GDDR7 memory, with the advertised speeds of 28Gbps, as a start. The fastest advertised speed for GDDR7, for that matter, is said to reach anywhere between 36 and 37Gbps
For that matter, little is known about AMD’s Infinity Cache specs for RDNA4 but that being said, one of the red chipmaker’s goal when launching its RDNA3-based cards back in 2022 was to match NVIDIA’s RTX 4080, albeit with a lower power draw. By comparison, the 7900 XT draws 20W less power, versus its green rival’s 320W TGP.
