Rumor | AdoredTV reveals a list of planned AMD Navi GPUs, estimates marginal performance improvements over the Vega 64 and Radeon VII
Continuing our coverage of the recent AMD Navi rumors, we are now seeing what GPUs are likely to form part of the Navi lineup. At the outset, it seems as if AMD is christening the RX 3000 series in line with the Ryzen 3000 chips. We are seeing a total of seven Navi GPUs — two high-end Navi20s, three mid-range Navi10s, and two entry-level Navi12s. Let's have a look at what we are hearing so far (the usual salty disclaimer applies).
Navi20 to have more or less the performance of Radeon VII
First up is the Navi20-based AMD Radeon RX 3090 XT and the RX 3090. The RX 3090 XT will feature 64 CUs and a TDP of 225 W. It is expected to offer a 10% performance boost compared to the Vega20-based Radeon VII for US$500. The RX 3090, on the other hand, will feature 60 CUs and will operate at a TDP of 180 W matching the Radeon VII in performance for US$430. We have already reported that the Navi20-based Radeon Instinct will likely be delayed to Q1 2020. That leaves us with the rest of the Navi10 and Navi12 family that are expected to launch at E3 2019. As detailed previously, AMD is struggling to optimize power efficiency for Navi20 so it might offer lesser clocks than the Radeon VII. Therefore, we expect AMD to take more time to properly optimize Navi20 and launch it sometime in Q1 2020.
Navi10 could be just what the doctor ordered
The mid-range GPU segment is a hotly contested one and NVIDIA has further consolidated its stronghold in this niche with the introduction of the GTX 1660 Ti. AMD is looking to undercut the NVIDIA RTX 2070 with the RX 3080 XT (56 CUs) while the RX 3080 is said to offer a 10% boost over the Vega 64 with 52 CUs at 175 W for US$280. The RX 3070 XT is rumored to retail for US$250 and will offer 48 CUs and a 160 W with performance equivalent to a Vega 64.
Navi12 could redefine entry-level
AdoredTV lists the RX 3070 and RX 3060 as using the entry-level Navi12 GPU. The RX 3070 is said to feature 40 CUs, 8 GB GDDR6 VRAM, and a 130 W TDP to take on the Vega 56 for US$200. The RX 3060 is rumored to sport 32 CUs, 4 GB GDDR6 VRAM, and a 75 W TDP to trade blows with the Polaris-based RX 580 for US$140. The numbers might seem great, but it is a bit hard to swallow a huge TDP and performance gap between the RX 3060 and the RX 3070 for a difference of just 8 CUs. It could be possible if AMD really played around with the clocks here, but we'll hold off any early conclusions for now.
So, apart from the Navi20 chips, we should be seeing the rest of the Navi lineup launch sometime during E3 2019. Desktop GPUs aside, AMD is also focused on the console market with both the Sony PlayStation 5 and the Xbox One 'Anaconda' expected to feature an RX 3080 XT-class GPU with 12.9+ TFLOPs of power and support for ray tracing.
