AMD appears to be testing multiple Mobility GPUs. The AMD Radeon RX 6000M Mobility GPUs are reportedly based on the RDNA 2 Architecture as well as Navi 23 and Navi 24. The discrete GPUs are meant for the gaming laptop segment, and hence, have a higher TBP profile.
New leaked information indicates AMD is conducting pre-production testing for its upcoming line of discrete graphics chips for the mobile computing segment. These chips will be based on the RDNA 2, Navi 23, and Navi 24 Core Architecture, which is also the basis for the AMD Radeon RX 6000 Series of dedicated graphics cards.
AMD Radeon RX 6000M Mobility GPUs Leak Confirms Cores and TDP Profiles:
AMD has several SKUs under testing for its Radeon RX 6000M family. It appears that AMD will initially introduce mainstream and entry-level variants based on the Navi 23 and Navi 24 GPU design. Interestingly, even the desktop graphics card segment hasn’t yet had a Navi 23 and Navi 24 GPU.
As per the latest report, AMD has at least three Navi 23 mobility GPUs for its RX 6000M family. The lineup will include a 90W, an 80W, and a 65W SKU. These are TGP (Total Graphics Power) profile figures. In other words, the TBP profiles would be slightly higher, but in no way would breach the 100W barrier.
Apart from the Navi 23, AMD is also reportedly testing at least two variants of discrete graphics chips that have Navi 24-based mobility GPUs. The Navi 24 XML SKU will feature a single 25W TGP variant. Meanwhile, the Navi 24 XM GPU will have a cTGP (Configurable Total Graphics Power) ranging from 35W, 42.5W, and all the way up to 50W. Incidentally, cTGP is not end-user configurable. Hence, it will be up to the OEMs and laptop manufacturers to decide which TGP to select for their own designs. Top-end laptop models with powerful cooling solutions could configure the discrete graphics chip with 50W cTGP.
Performance Expectations From AMD Radeon RX 6000M Mobility GPUs:
Experts indicate the performance of the AMD Navi 23-based GPUs could be similar to the Radeon RX 5700M series mobility GPUs but with better efficiency. It is possible that AMD might just embed 8 GB RAM, which would be an upgrade of 2 GB over the previous generation. As for the Clock Speeds, these GPUs could go as high as 2 GHz.
The unreleased AMD Radeon RX 6000M GPUs should succeed the Radeon RX 5500M and RX 5300M GPUs which are based on the Navi 14 (RDNA 1) GPU. The Radeon RX 5500M and RX 5300M come with 4 GB and 3 GB GDDR6 memory, respectively. The Navi 24 XM GPU could feature an 8 GB GDDR6 memory config while the Navi 24 XML GPUs could have 6 GB GDDR6 memory.

The AMD Radeon RX 6000M GPUs should compete with mainstream GeForce RTX 30 mobility GPU. These GPUs would be embedded in laptops with Lucienne (Renoir-refresh, ZEN 2) and Cezanne (ZEN 3) based Ryzen 5000 Mobility CPUs, and they would obviously be marketed as gaming.
Although yet to be confirmed, based on the new Architecture, AMD might just offer the popular ‘Infinity Cache’ within these Mobility GPUs. Additionally, buyers can expect the SAM feature as well.
