AMD's next-generation rDNA-powered Navi GPUs for the Radeon RX range will apparently make its first appearance at CES 2020. This, along with a few other rumors about AMD's Radeon and Threadripper product lineups, have revealed by Chiphell leaker, Wjm47196.
AMD To Intro 2nd Generation rDNA Based Radeon RX Navi GPUs at CES 2020 – Ray Tracing Support & More Onboard
Rumor comes from the Chiphell user who was previously very accurate with his leaks like the Polaris 30 (Radeon RX 590) launches in Q4 2018, Radeon VII in Q1 2019 and 7nm Navi mainstream cards arriving to the advanced enthusiast-quality variants in 2019. With a good track record to begin, let's see what the latest information is that leaker has for us.
According to him, AMD's plans for their 2nd Generati on rDNA-based Radeon The RX Navi GPU range is offering a product preview at CES 2020. It would be interesting and meaningful as CES 2020 will be a huge event for AMD to unveil their 2020 product portfolio which includes Zen 3 and 2nd Gen rDNA based products for mainstream, enthusiast, notebook and server markets. It has already been confirmed that the rDNA 2 GPU architecture is in-design and scheduled to be launched in 2020. Some of the features that can be expected from 2nd Generation rDNA Navi GPUs:
- Optimized 7nm + process node
- Enthusiast-grade desktop Graphics Card Options
- Hardware Level Ray Tracing Support
- A Blend of GDDR6 and HBM2 Graphics Cards
- More Efficient Than First-Gen Navi GPUs
not much we know about RDNA 2 apart from the rumors, but what AMD has officially talked about is Ray Tracing which will be available on their next gen GPU range. With its next-gen RDNA architecture, AMD plans to have hardware-level integration on its GPUs to support real-time beam tracking in-game. This would put them on par with NVIDIA's RTX technology, which implemented radiation tracking support through hardware-level integration last year with their GeForce RTX 20 series card.
AMD also wants to drive RDNA 2 towards the higher spectrum of the market. While the first generation of RDNA GPUs work well in the $ 300- $ 500 segments, we would probably see a range of enthusiast designs with RDNA 2-based Radeon RX graphics cards. These would take the fight against NVIDIA's RTX 2080 SUPER / RTX 2080 Ti, but NVIDIA is not the company that would just sit quietly through a competitor's launch. Plans for NVIDIA's 7nm GPUs are ongoing and it is likely that we would see a big launch in 2020 for their next generation of graphics architecture, probably known as & # 39; Ampere & # 39 ;. There are also rumors that NVIDIA introduced an even faster RTX 2080 Ti in the form of RTX 2080 Ti SUPER in early 2020, which would definitely keep AMD GPUs away from reaching the performance crown anytime soon.
It should also be noted that advanced Navi GPUs can retain high bandwidth memory design as the current flagship. While AMD has GDDR6 memory on its mainstream RDNA-based cards, the company is likely to move on with the newer HBM2E VRAM.
HBM2E DRAM comes in 8-Hi stack configuration and uses 16 Gb of memory, stacked together and clocked at 3.2 Gbps. This would result in a total bandwidth of 410 GB / s on a single and 920 GB / s with two HBM2E stacks, which is just crazy. In addition, DRAM has a 1024-bit wide bus interface which is the same as the current HBM2 DRAM. Samsung says that their HBM2E solution, when stacked in 4-way configuration, can offer up to 64 GB of memory with 1.64 TB / s bandwidth. Such products would only be suitable for servers / HPC workloads, but an advanced graphics product for enthusiasts can hold up to 32 GB of memory with just two stacks, which is twice as much memory as Radeon VII.

AMD also to introduce a new Navi 10-based graphics card in $ 250- $ 300 US Segment, Full Navi 14 GPU Exclusive to Apple
The other rumors that the leaker points out are that AMD would soon introduce a third desktop class Navi 10 graphics card. The new Radeon RX graphics card would be further cut compared to the Radeon RX 5700, which in itself is a cut down version of the Radeon RX 5700 XT. The new graphics card would suffer from $ 250- $ 300 pricing in the US, which means AMD looks to compete with the mainstream GeForce GTX 16.
AMD Radeon RX 5700 (non-XT) is already well 25% faster than GTX 1660 SUPER recently introduced at $ 229 US. If AMD somehow manages to offer up to 10-15% better GPU performance than GTX 1660 SUPER at about $ 249- $ 269 US, than it would be a very good and competitive solution since Navi 10 GPUs are currently starting at $ 349 US.
The other news, which we probably already got the hint from the recently launched MacBook Pro, is that AMD's full Navi 14 GPU would be held exclusively for Apple which means Radeon RX 5700 XT could probably end up with 22 CU on 1408 power processors, leaving the entire 24 CU array with 1536 power processors available only for Apple products.

Again, as credible as the source may be, this information is still a rumor so consider it as such . We will announce if there is more information about the 2nd generation Navi on the horizon.
