The existence of Navi 14 or low-end Navi has been known for a few months now. We reported about the same shortly before the announcement of the Radeon RX 5700 series, and it seems like the rumor is finally developing into a solid product stack, set to replace the Polaris based RX 570 and 580.
The source of this leak is reputed Twitter chip detective, @Komachi who had provided scant details on Navi 14 quite a while back. The low-end Navi part was spotted on CompuBench and will leverage the same RDNA (1st Gen) architecture, a hybrid of the older GCN and the brand new RDNA design.
The Navi 14 GPUs should slide in right below the RX 5700 lineup aiming to replace the RX 570 and 580 and at the same time giv stiff competition to NVIDIA’s GTX 16 series lineup. Sapphire had trademarked the RX 5900, 5800, 5700 and the 5600 as potential names for upcoming products and it’s very likely that the new GPUs will follow the RX 5600 naming scheme.
According to the Twitter source, this particular Navi 14 chip will pack 24 Compute Units, resulting in a total of 1536 Steam processors (64×24). The shaders will run at a frequency of 1,900 MHz, almost the same as the RX 5700 series GPUs.
Looking at the specs, we can say with a good deal of certainty that the RX 5600 GPUs or Navi 14 will perform in the same ballpark as the GTX 1660 Ti and the GTX 1660, sitting right above the RX 570. I expect these cards to leverage GDDR5 memory to cut down costs. The VRAM and bus width should be around 8GB and 128/192 bit, respectively. Like Navi 10, it’ll also leverage the same 7nm node from TSMC.
After Navi 14, we expect to see Navi 20 or “Big Navi” from AMD which will compete with the likes of the RTX 2080 Ti and also power the next-gen Xbox Scarlett and PS5 consoles.
