The RDNA 4 series is expected to include various GPUs, including the high-end Navi 48 and mainstream Navi 44 models. The GPUs are designed for use in gaming systems and offer a number of technical improvements over their predecessors. Particularly noteworthy are the innovations in the area of ray tracing, which will probably also be used in future games consoles. The Radeon RX 8000 series GPUs will feature different Infinity Cache sizes and memory bus configurations to provide a balance between performance and efficiency. The main models and their specifications are summarized in the table below:
Model | GPU chip | Memory bus | Memory speed | Memory size | Infinity Cache | Total bandwidth |
---|---|---|---|---|---|---|
Radeon RX 8000 | Navi 48 | 256-bit | 20 Gbps | 16 GB GDDR6 | 64 MB | 640 GB/s |
Radeon RX 8000 | Navi 48 | 256-bit | 18 Gbps | 16 GB GDDR6 | 64 MB | 576 GB/s |
Radeon RX 8000 | Navi 48 | 192-bit | 19 Gbps | 12 GB GDDR6 | 48 MB | 456 GB/s |
Radeon RX 8000 (entry level) | Navi 44 | 128-bit | N/A | N/A | 32 MB | N/A |
The Navi 48 GPUs are at the heart of the Radeon RX 8000 series. These GPUs are designed for performance-intensive applications and feature a 256-bit memory bus available in two main configurations: one with 16GB of GDDR6 memory at 20Gbps and another with 16GB of GDDR6 memory at 18Gbps. A third configuration with a 192-bit memory bus and 12 GB GDDR6 memory at 19 Gbps is also offered. These different configurations offer different bandwidths from 640 GB/s to 456 GB/s. In addition to the memory configuration, the Navi 48 GPUs offer an Infinity Cache, which provides additional bandwidth. This cache works as an additional memory that sits directly next to the GPU and speeds up data processing by reducing latency.
For the mainstream market, AMD is planning to introduce GPUs based on the Navi 44 chip. These models are more simply equipped and offer a 128-bit memory bus interface. They will have 32 MB of Infinity Cache and a lower overall core count. These GPUs are intended for less demanding applications or for price-conscious users. The launch of the AMD Radeon RX 8000 “RDNA 4” GPU family is planned for the first quarter of next year. AMD is expected to officially unveil these new GPUs at CES 2025. Further technical details and performance evaluations are expected in the run-up to this event.
AMD’s Radeon RX 8000 series promises a range of new technologies and improvements in the RDNA 4 architecture. With different memory bus and Infinity Cache configurations, AMD offers a wide range of GPUs suitable for both high-end and mainstream gamers. With a planned launch next year, it remains to be seen how these new models will compare to existing products on the market.
The table provides a clear overview of the expected technical specifications and helps to better understand the differences between the models. While the high-end GPUs of the Navi 48 series offer high bandwidth and plenty of memory, the mainstream models with reduced specifications are suitable for less intensive applications.
With the introduction of this new series, AMD is expected to once again try to strengthen its position in the graphics card market, especially by improving ray tracing capabilities and adapting to upcoming technologies in the gaming sector. More information is expected in the coming months, especially as the official launch date approaches.
