2048 cores for the RX 6600 XT and 1792 for the RX 6600Citing leaks on the Asian ChipHell forum, a href="https://videocardz.com/newz/amd-radeon-rx-6600-xt-allegedly-features-2048-cores-rx-6600-gets-1792" target="_blank">VideoCardz reports it looks like the Radeon RX 6600 XT will feature 2048 streaming processors. This model will thus have a full Navi 23 GPU, while the Radeon RX 6600 non-XT will get a cut-down version with 1792 cores. Both models will allegedly get a 128-bit memory bus in combination with 8GB GDDR6 memory.
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. -- VideoCardzThe launch date of the RX 6600 series remains a mystery. Both cards are expected later this quarter -- although further delays can't be ruled out. A Radeon RX 6700 is also still expected -- but it's been pretty quiet about that model.
Navi 24 gets 1024 streaming processorsVideoCardz also came across details about the Navi 24 "Beige Goby" GPU. The codename of this model has appeared in recent Linux drivers from AMD. The Navi 24 GPUs reportedly have 16MB Infinity Cache. These Beige Goby chips could launch as either the Radeon RX 6500 or RX 6400 series.
Configurations with up to 1024 streaming processors are planned. It's unknown when the Navi 24 GPUs are expected to hit the market. It's believed to be the final member of AMD's RDNA2 lineup.
