The rumor comes from @All_The_Watts who posted a very cryptic message over at social platform, X. The post talks about two next-gen AMD GPUs based on the RDNA 4 graphics architecture which are supposedly going to power the Radeon RX 8000 graphics card family. Now there is limited info regarding Navi 4 available but two SKUs have already been spotted under the "GFX12" family so it looks like these two SKUs are in the early testing phase.

The rumor is straightforward:

• RDNA 3 (Navi 31 Top) > RDNA 4 Navi 48 (Top) > RDNA 3 Navi 31 (Cut)
• RDNA 3 (Navi 32 Top) > RDNA 4 Navi 44 (Top) > RDNA 3 Navi 33 (Top)

So first up, we have the AMD Navi 48 GPU, the supposedly top RDNA 4 GPU die. This GPU is said to be slower than the top Navi 31 die which is used on the Radeon RX 7900 XTX (Navi 31 XTX) but will be faster than the cut-down Navi 31 GPU die featured on the Radeon RX 7900 GRE. This should put the performance of the next-gen Navi 48 GPU around GeForce RTX 4070 Ti SUPER and the Radeon RX 7900 XT.

The second chip is the mid-tier Navi 44 GPU which is the slowest of the two RDNA 4 chips and is stated to be faster than AMD's Navi 33 GPU (Hotpink Bonefish) featured on the Radeon RX 7600 series but slower than the Navi 32 (Wheatnas) GPUs which are featured on the Radeon RX 7800 & RX 7700 series. based on this, we can expect performance to be somewhat close to the RX 7700 XT and GeForce RTX 4060 Ti graphics cards.

Now while the performance is either matching existing GPUs or slower than expected, it should be remembered that AMD's
