AMD Navi 22, Navi 23 and Navi 24 Mobile GPUs That Will Power AMD Radeon RX 6000M Discrete Laptop Graphics Leak Online

More information about the as-yet-unreleased discrete graphics chip from the next-gen AMD RDNA 2 Architecture is now available. These graphics chips will succeed the Radeon RX 5500M GPUs and are expected to be inside gaming laptops.

The AMD Radeon RX 6000M is the next-generation discrete mobility graphics solution that will have the RDNA 2, Navi 22, Navi 23, and Navi 24 Core Architecture. These graphics chips will be embedded inside laptops with Lucienne (Renoir-refresh, ZEN 2) and Cezanne (ZEN 3) based Ryzen 5000 Mobility CPUs.

AMD Navi 23 GPU Specifications:

AMD Navi 23 GPU will be at the heart of the Radeon RX 5500M successor, which was based on Navi 14. The Navi 23 GPU would be offered with Total Graphics Power (TGP) targets of 65W, 80W, and 90W. The GPU may also be offered with higher TGP for desktop variants. However, AMD hasn’t offered confirmation about the existence of the Navi 23 desktop-grade graphics card.

New reports indicate the Navi 23 GPU will be a 128-bit GPU, with support of up to eight GDDR6 memory modules. This means GPU would be accompanied by either 4GB or 8GB VRAM. The GPU does support DirectX 12_1, Vulkan 1.1, OpenGL 4.6, and OpenCL 2.2 APIs. But a new report claims it also supports Liquid VR, a set of technologies for virtual reality.

The Navi 23 could also support a total of 5 display outputs. Moreover, the display could be routed through DisplayPort, HDMI 2.1, and even USB Type-C. In terms of video coding, the GPU will reportedly support VP9, HEVC, H.265, VC1 decoders. The GPU has a PCI Express 4.0 x8 interface.

The Navi 23 GPU has a maximum clock speed of 2350 MHz. This is certainly lower than the Navi 21 GPU, but the reduction might have been necessary to meet the power requirements.

AMD Navi 22 Mobility Graphics Solution:

The AMD Navi 22 GPU might arrive within the AMD Radeon RX 6700M. This will obviously be a part of the upcoming RDNA 2 lineup. The GPU has a die size of 334.54 sq. mm, which is smaller than the Navi 21 GPU which has a die size of 520 sq. mm.

The reduction continues in terms of Compute Units (CU) as well. The Navi 21 offers up to 80 Compute Units (5120 Stream Processors). Meanwhile, the Navi 22 could offer up to 40 CUs (2560 Stream Processors). The Mobility Version of this GPU might have slightly lower CUs.

Another leak claims this GPU has a TGP profile of 146W, but this figure appears quite high for a mobility graphics solution. This GPU would have a memory bus of 192-bit, which is the same as the desktop equivalent. This translates to the possibility of graphics cards based on this GPU to pack 6 GB or even 12 GB of GDDR6 memory.

The second possible variant would have three TGP profiles: 90W, 110W, and 135W. This graphics card has a memory bus width of 160-bit, suggesting 5 GB or 10 GB of GDDR6 memory.
