Although for many months there have been reports from various sources that AMD is planning a 6nm version of the GPU Navi 22 a Navi 23, the currently announced refresh of mobile Radeons 6000 does not contain such a GPU. If we rank the possible reasons from the most probable, it may be that the 6nm capacities of TSMC are not yet at a level at which AMD could afford to move other products to this process (Instinct already produces core accelerators on it). Aldebaran, GPU Navi 24 and APU Rembrandt), it may also be that the draft 6nm versions are not yet ready and, finally, that this plan has been canceled.
Most of the offer of new models is therefore based on 7nm chips and, with a few exceptions, it is a GPU Navi 23 (known from the desktop as Radeon RX 6600 / XT) modified in various ways. This is basically because these new models are not a replacement for the existing range, but only a supplement.
|6850M XT||Navi 22||7nm||2560||2463 MHz||96 MB||192bit||12 GB 18GHz||130-165W|
|6800M||Navi 22||7nm||2560||2300 MHz||96 MB||192bit||12 GB 16GHz||145W+|
|6700M||Navi 22||7nm||2304||2300 MHz||80 MB||160bit||10 GB 16GHz||≤135W|
|6650M XT||Navi 23||7nm||2048||2162 MHz||32 MB||128bit||8 GB 16GHz||80-120W|
|6650M||Navi 23||7nm||1792||2222 MHz||32 MB||128bit||8 GB 16GHz||80-120W|
|6600M||Navi 23||7nm||1792||2177 MHz||32 MB||128bit||8 GB 14GHz||≤100W|
|6500M||Navi 24||6nm||1024||2191 MHz||16 MB||64bit||4 GB 18GHz||35-50W|
|6300M||Navi 24||6nm||768||1512 MHz||8 MB||64bit||2 GB 18GHz||25W|
Some discrepancy concerns the table of specifications that leaked before CES. She erroneously states that the Radeons built on Navi 24 they have a 128bit bus, which is not possible in principle (the kernel is physically 64bit). This is a mistake that was corrected in later materials and therefore we also present 64bit.
The “S” series, whose TDP does not exceed 100 watts, stands purely on the GPU Navi 23 with minor variations:
|RX 6800S||Navi 23||7nm||2048||1975 MHz||32 MB||128bit||8 GB 16 GHz||≤100W|
|RX 6700S||Navi 23||7nm||1792||2177 MHz||32 MB||128bit||8 GB 14 GHz||≤80W|
|RX 6600S||Navi 23||7nm||1792||2191 MHz||32 MB||128bit||4 GB 14 GHz||≤80W|
The new Radeon 6000M and 6000S models will appear in this year’s offer of laptop manufacturers.
