AMD Radeon RX 6600 XT allegedly features 2048 cores, RX 6600 gets 1792

AMD Radeon RX 6600 series with Navi 23 GPU and 8GB memory

According to a Chiphell leaker, both of the upcoming Radeon RX 6600 series graphics cards would feature Navi 23 GPU.

While there are no pictures or screenshots that would confirm the specifications of the upcoming Radeon RX 6600 graphics cards, there certainly are some rumors floating around the web, especially on Chinese forums. A place where many of those rumors start is Chiphell, which now has an interesting thread with alleged specifications of RX 6600 models. The data is supposedly based on AMD engineering samples, suggesting that they are as accurate as it gets at this point of time.

According to the leaker, AMD Radeon RX 6600 XT would feature Navi 23 GPU with 2048 Stream Processors. That said, the XT variant would feature fully spec’ed Navi 23. A cut-down variant would be used by RX 6600 non-XT which is allegedly going to feature 1792 cores. Both configurations of Streaming Processors have been used by AMD for many mid-range graphics cards in the past.

It is said that both models would feature 8GB GDDR6 memory across a 128-bit interface. This has somewhat been confirmed by ASRock, who had submitted a filing to EEC earlier this week with the RX 6600 series featuring 8GB of memory. The leaker also provides performance figures claiming that RX 6600 XT scores 9439 points in 3DMark Time Spy (Graphics) while the non-XT card scores 7805 points. Assuming that those numbers are correct, both cards would compete with AMD’s own RX 5700 XT and RX 5700 models respectively.

The lineup of RDNA2 based models is slowly becoming full. With this generation, AMD has started from the top by releasing Navi 21 models first. In March we had an update with the first Navi 22 part (RX6700XT) but we are expecting a cut-down variant featuring this GPU soon. With the rumored RX 6600 specifications in mind, one would guess that RX 6700 non-XT would get a 2304 Stream Processor. When it comes to the memory though, we have only seen leaks mentioning 6GB.
