Navi 12 RX 5800 with 4096 SPs could be AMD's answer to the RTX 2080 Ti
After having launched Navi 10-based RX 5700 series at competitive prices and a Navi 14 purportedly in the works, AMD is apparently not interested in calling it a day. Rumors are running wild that AMD is working on a Navi 12 GPU (RX 5800?) with 4096 SPs (64 CUs) that will directly take on the heavyweights, the NVIDIA RTX 2080 Super and possibly even the RTX 2080 Ti. This interesting tip comes from famed leakster Komachi_Ensaka who has been pretty spot-on with most CPU and GPU leaks so far. What we are learning now is still speculative so the usual disclaimers apply.
From what we get to hear, AMD is prepping Navi 12 to target NVIDIA's TU104 die to go against the RTX 2080 Super with some variant of Navi 12 also aiming for the TU102 in the RTX 2080 Ti. Now, this is where things start to get confusing as so far we've known Navi 12 to be a lower-end variant with presumably an RX 5600 moniker and Navi 20/21 being the supposed Goliath. However, Komachi's tweet indicates that Navi 12 is indeed a "big GPU".
Nomenclature aside, the RTX 2080/Ti killer could have anywhere between 64 to 80 CUs (4096-5120 SPs). We are not sure if the Navi 12/20 die-size can accommodate 80 CUs but 64 CUs isn't something to scoff at either. But all this has been so far thought to be reserved for the RDNA 2 launch sometime in 2020. Could AMD surprise everyone by launching a 7nm 'Navi 12' with such specs this year itself? We heard recently that NVIDIA might not be launching the rumored RTX 2080 Ti Super after all. The question is, if AMD does indeed offer an RTX 2080 Ti competitor, will NVIDIA be forced to respond? Your guess is as good as ours.
