56 processing units with 2.1 GHz clock speed and 16 GB VRAM

AMD's next-gen Radeon RX 8000 “RDNA 4” GPU has leaked on Geekbench, giving us a hint at core count and memory specs.

AMD Radeon RX 8000 GPUs now appear on Geekbench 6, feature 56 RDNA 4 compute units and 16 GB VRAM

AMD's RDNA 4 GPUs are expected to launch next year as part of the Radeon RX 8000 lineup, but the first samples have already appeared on Geekbench, meaning internal testing is now underway as Team Red prepares for a reveal. Several entries of a SKU within the RDNA 4 lineup have been spotted along with their specifications.

Let's start with the details: The GPU appears with the device ID “GFX1201”, which confirms that it is a Navi 48 SKU, the largest of the two Navi 4X chips being introduced as part of the RDNA 4 family. AMD's Navi 48 GPU is making the rounds in online shipping manifests.

The Navi 48 “GFX1201” GPU is listed with 28 Compute Units, which should equate to 56 Compute Units given the new RDNA 3 series configurations. Each GPU has a shader engine with two Compute Units. If this stays the same for RDNA 4, we can expect up to 56 Compute Units, which is between the RX 7700 XT (54 CU) and RX 7800 XT (60 CU) models.

The AMD Radeon RX 8000 “RDNA 4” GPU is also listed with its clock speed configured at 2101 MHz or 2.1 GHz. Current RDNA 3 GPUs can easily overclock to 2.5-2.6 GHz, and since the RDNA 4 chips are expected to use a better node and new architecture, the clock speeds seem a bit low, but we can expect better frequencies as more samples appear closer to launch.

Last but not least, we have the AMD Radeon RX 8000 “RDNA 4” GPU SKU's memory listed at 16GB, which is the same as the RX 7800 XT and RX 7900 GRE. This confirms a 256-bit bus interface for high-end RDNA 4 cards and we can expect certain configurations to get 192-bit bus interfaces with 12GB VRAM capacities. There is currently no information on the type of memory used here, but previous reports have suggested that AMD will use GDDR6 memory for its RDNA 4 lineup with a clock speed of around 18Gbps.

In terms of performance, the leaked AMD Radeon RX 8000 “RDNA 4” GPU currently behaves like an iGPU in the OpenCL benchmark, which is one hundred percent due to its early nature. We should disregard this performance for now and wait for better results in the future.

That's all as far as the Geekbench listing goes, but we can definitely expect a lot of new updates with the Radeon RX 8000 series AMD RDNA 4 GPUs. Some of the new features we've already talked about are brand new ray tracing engines that will bring big improvements over the last generation. Again, the AMD RDNA 4 GPUs are aimed at the mainstream and high-end segments, bringing Navi 31 performance to the $400-$500 price range. We'll hear more about the cards at CES.
