AMD is yet to announce its challengers to the likes of the RTX 3070 and RTX 3080, but rumoured clock speeds suggest that at least one Navi 21 SKU will be capable of reaching 2.4 GHz. The Navi 21 XT is thought to offer 16 GB of GDDR6 RAM too, along with a 255 TGP. The Navi 21 XL and XLE will supposedly be no slouches, either.

We are just over a week away from the announcement of the Radeon RX 6000 series, but some interesting details about the upcoming cards have been shared online. Shared by @_rogame and @patrickshur_, the information is reputed to be the clock speeds of AMD's 'Big Navi' graphics cards. According to @_rogame, AMD will release four variants of the Navi 21 GPU, called Navi 21 XL, XLE, XT and XTX.

As the screenshots below indicate, the XT variants are thought to be AMD's more premium offerings, with the XL and XLE being the company's two entry-level Navi 21 cards. Apparently, reference cards will offer lower clock speeds than AIB custom ones, which is not much of a surprise. Navi 21 XL and XT will reputedly exceed 2.1 GHz though, with the XT variants apparently being capable of reaching 2.4 GHz.

@patrickschur_ and @_rogame believe that 2.4 GHz represents the peak game clock for the Navi 21 XT, which would be a huge increase over the game clock of the RX 5700 XT. Additionally, @patrickshur_ believes that the Navi 21 XT will manage this with a 255 W TGP (total graphics power) and will be paired with 16 GB of GDDR6 VRAM.

@_rogame speculates that AMD will brand the Navi 21 XT as the RX 6800 XT, while the Navi 21 will be the RX 6800. Both may have 72 Compute Units (CUs), with 80 CUs reserved for the RX 6900 XT, which will use the Navi 21 XTX GPU. Presumably, the Navi 21 XLE would be the RX 6900 based on those names, but we shall find out definitively on October 28 at AMD's launch event.
