AMD rounded off the summer by taking the architecture RDNA 2 to the middle class. The graphics card in question was the Radeon RX 6600 XT, whose recommendation was placed just below Nvidia’s Geforce RTX 3060 Ti and was well above the RTX 3060. Next in line is the RX 6600 without the XT, where the Navi 23 graphics circuit is scaled down to reach a lower price point.
The recurring leak Videocardz can now reveal that the launch of the Radeon RX 6600 XT is taking place on October 13th. This is according to documents sent out to partner manufacturers, where it is stated in detail when graphics cards will be sent to AMD and when the media will receive a graphics card in hand at the earliest. This is followed by a confidentiality agreement that expires on 13 October.
The graphics circuit in the Radeon RX 6600 is Navi 23 with which AMD disables 4 of 32 computing units (CU). The number of stream processors goes down completely sonic from 2,048 on the RX 6600 XT to 1,792, a dropout rate of 12.5 percent. As the clock frequencies light up with their absence, it remains to be seen to what extent it affects performance.

What is clear, however, is that AMD leaves the amount of Infinity Cache untouched at 32 MB and likewise, the RX 6600, like its big brother, gets 8 GB of GDDR6 over a 128-bit memory bus. The effective clock frequency for the memory is expected to land at the same level as the entire RX 6000 series, 16,000 MHz, which gives a theoretical bandwidth of 256 GB / s.
In conclusion, it appears that the Radeon RX 6600, like the RX 6600 XT, will be without a reference design. What the model’s official price tag lands on is not currently known, but since the RX 6600 XT is at 379 US dollars (USD) and the Geforce RTX 3060 is at 329 USD, a price around 299 USD is not entirely unlikely.
