The full disclosure of the RDNA3 desktop lineup has finally been pictured

Though AMD has not yet formally unveiled the Navi 32, recent disclosures by PowerColor of the Radeon RX 7800 XT Red Devil‘s page have revealed the Navi 32 GPU. This unveiling, featuring a combination of one GCD and four MCDs, aligns perfectly with previous rumors.

As it stands, there are four RDNA 3 architecture chips in total, namely, the Navi 31, used for the Radeon RX 7900 XTX/XT; the Navi 31 XL, used for the Radeon RX 7900 GRE; the Navi 32, used for the Radeon RX 7800 XT; and the Navi 33, used for the Radeon 7600. In addition to releasing the renderings of the Navi 32, PowerColor has actually provided renderings of several other Navi 3x chips through its Red Devil and Hellhound series products, offering clarity and comprehensiveness.

According to prior statements, the Radeon RX 7800 XT, equipped with the Navi 32, will fully enable all of its compute units, consisting of 60 CUs, or 3840 stream processors, with an Infinity Cache of 64MB, 16GB of GDDR6 video memory, a memory bit width of 256 bits, and a memory speed likely at 20Gbps. The Navi 32, like the Navi 31, adopts an MCM design, though it has been reduced from GCD x1 + MCD x6 to GCD x1 + MCD x4, with a chip area of approximately 348 mm².

The recently launched Radeon RX 7900 GRE, fitted with the Navi 31 XL, seems almost identical to the Navi 31, albeit using compact packaging. Although both appear to have a GCD x1 + MCD x6 configuration, rumors suggest that only four are actually functional, with the remaining two being dummy modules. This reduces this GPU’s memory bit width from 384 bits to 256 bits and its Infinity Cache from 96MB to 64MB.

Next, AMD may introduce the Radeon RX 7700 XT, featuring 12GB of GDDR6 memory and a memory bit width of 192 bits, possibly equipped with the Navi 32.
