AMD Radeon RX 8000 (RDNA4) GPUs Expected To Feature 18 Gbps GDDR6 Memory

Kepler was among those who exposed AMD's decision to abandon its larger Navi4 GPU plans, a move AMD itself has gradually acknowledged. Currently, there are no indications of larger Navi GPUs slated to replace the RX 7900 models in the near future. However, changes are expected in the mid-range and entry-level sectors with the emergence of Navi 48 and Navi 44 GPUs built on the RDNA4 architecture.

These GPUs are expected to drive cards such as the Radeon RX 8800, 8700, 8600, and 8500 series, varying based on whether it's a desktop or mobile lineup. AMD has not provided confirmation on the arrival time of these GPUs or the RDNA4 launch range. However, recent insights indicate that next-generation GPUs may use relatively slow 18 Gbps GDDR6 memory, despite expected mass production of faster GDDR7 memory by the end of this year.

18 Gbps memory speed is currently used by certain desktop GPUs such as the RX 7900 GRE or RX 7700 XT, all with Navi 33 models. For the mobile form factor, this speed is maxed out by AMD.

In contrast, the upcoming GeForce RTX 50 series is expected to launch with 28 Gbps GDDR7 memory by the end of the year. However, this speed is lower than the fastest GDDR7 speeds discussed by memory companies, which could potentially reach 36-37 Gbps in the future, although not for early GPUs that take advantage of this technology.

What is potentially important is the limited information available regarding the details of the RDNA4 Infinity Cache. According to current data, these GPUs may not require fast memory. Currently, there's no indication that the RDNA4 series will power higher-end models, and it's conceivable that they won't be as fast as current high-end models.
