AMD Introduces Radeon RX Lineup with 2nd Generation rDNA-based Navi GPUs at CES 2020AMD’s next-generation rDNA-based Navi GPU for the Radeon RX lineup will debut at the CES 2020. This was revealed by Chiphell leaker Wjm47196, along with several other rumors surrounding AMD’s Radeon and Threadripper product lineup.
AMD also wants to push RDNA 2 to the highest-end spectrum on the market. First-generation RDNA GPUs perform exceptionally well in the $ 300- $ 500 segment, but you can see a variety of enthusiast-class designs using RDNA 2-based Radeon RX series graphics cards. These will fight NVIDIA’s RTX 2080 SUPER / RTX 2080 Ti, but NVIDIA is not a company that quiets the launch of competitors. NVIDIA’s 7nm GPU plans are underway, and in 2020 there will likely be a massive release of the next-generation graphics architecture, perhaps known as ‘Ampere’. Rumor has it that NVIDIA is introducing a faster RTX 2080 Ti in the form of the RTX 2080 Ti SUPER. Early 2020 AMD GPUs will soon be prevented from reaching the performance crown.It should also be pointed out that advanced Navi GPUs can maintain the same high bandwidth memory design as current flagships. AMD has GDDR6 memory on mainstream RDNA-based cards, but the company will continue to use the latest HBM2E VRAM.HBM2E DRAM comes in an 8-Hi stack configuration and is stacked together using 16Gb memory die and clocked at 3.2Gbps. This results in a single bandwidth with two HBM2E stacks and a total of 410 GB / s at 920 GB / s. Best of all, DRAM now has the same 1024-bit wide bus interface as HBM2 DRAM. Samsung said its HBM2E solution can deliver up to 64GB of memory at 1.64TB / s bandwidth when stacked in a four-way configuration. These products are only suitable for server / HPC workloads, but advanced graphics products for enthusiasts can provide up to 32GB of memory with only two stacks, twice that of Radeon VII.AMD GPU architecture comparison:
The AMD Radeon RX 5700 (non-XT) is 25% faster than the GTX 1660 SUPER, which was recently introduced for $ 229. If AMD offers about 10-15% better GPU performance than the GTX 1660 SUPER at US $ 249- $ 269 US, this would be a very good and competitive solution, since Navi 10 GPUs now start at $ 349 US.Another hint already at the recent MacBook Pro launch is that AMD’s entire Navi 14 GPU is reserved for Apple. In other words, the Radeon RX 5700 XT can end up with 22 CU on a 1408 stream processor, and the entire 24 CU die with a 1536 stream processor is only available to Apple products.AMD Navi 14 Mobility GPU Lineup:
