AMD’s RDNA2-based cards are just around the corner, with the company’s full debut of the secrecy-shrouded cards being set for October 28th. Rumors of high clocks on AMD’s new architecture – which were nothing more than unsubstantiated rumors up to now – have seemingly been confirmed, with Patrick Schur posting on twitter some specifications for upcoming RNDA2-based Navi 21 XT. Navi 21 XT falls under the big Navi chip, but likely isn’t the top performer from AMD – the company is allegedly working on a Navi 21 XTX solution, which ought to be exclusive to their reference designs, with higher clocks and possibly more CUs.

The specs outed by Schur are promising, to say the least; that AMD’s Big Navi can reach clocks in excess of 2.4 GHz with a 250W+ TGP (quoted at around 255 W) is certainly good news. The 2.4 GHz (game clock) speeds are being associated with AIB cards; AMD’s own reference designs should be running at a more conservative 2.3 GHz. A memory pool of 16 GB GDDR6 has also been confirmed. AMD’s assault on the NVIDIA 30-series lineup should embody three models carved from the Navi 21 chip – the higher performance, AMD-exclusive XTX, XT, and the lower performance Navi 21 XL. All of these are expected to ship with the same 256 bit bus and 16 GB GDDR6 memory, whilst taking advantage of AMD’s (rumored, for now) Infinity Cache to make up for the lower memory speeds and bus. Hold on to your hats; the hype train is going full speed ahead, luckily stopping in a smooth manner come October 28th.
