Back during Computex 2019, AMD unleashed its Navi GPU architecture to the world. To date, both the mid-range Radeon RX 5700 series and entry-level RX 5500 have been made public, and a high-end Navi GPU appears to be ways off. However, a recent Linux driver entry seems to suggest that AMD is prepping not one, but five additional Navi 14 GPU variants.
The discovery of the Linux entry was first posted on Reddit and lists down a Navi 14 XT, XTM, XLM, XTX, and XL. Each entry is also followed by what is assumed to be the peak clock of each GPU variant. For those unfamiliar with the parlance, peak clock generally refers to a GPU’s highest achievable frequency, but the definition of the term does differ between AMD and NVIDIA GPUs.
Getting back on point, the lowest recorded frequency in the list is 1181MHz, which belongs to the Navi 14 GPU with the XLM moniker. The variant with the highest clockspeed of 1670MHz belongs to the Navi 14 XT GPU.
There isn’t a whole smorgasbord of information accompanying the entry, but there are still interesting points to note. The XTX moniker was initially reserved for the 50th anniversary edition of the RX 5700 XT, but as pointed out by Videocardz, it wouldn’t make any sense for AMD to reserve the name for an SKU that has already been out on the market for nearly half a year.
Likewise, the Navi 14 XTX GPU on the list is reportedly a Radeon RX 5500 XT, and the clockspeed of the XTM and XL GPUs point at them actually being the Radeon RX 5500 and RX 5500M. Given how nearly identical they both are to AMD’s advertised clockspeeds for the entry-level GPU.
In any case, this is all still just speculation and hearsay and AMD still hasn’t released any official statement regarding the matter. So, as with all stories of such nature, do take this bit of news with a liberal sprinkling of salt.
