AMD’s first GPU built on the N6 (6 nm) silicon fabrication process isn’t some big RX 7000 series behemoth, but the smallest chip from the Navi 2x GPU family, codenamed Navi 24. Based on the same RDNA2 graphics architecture as the rest of the RX 6000 series, the Navi 24 physically packs 1,024 stream processors across 16 compute units (8 WGPs), and on the RX 6500 XT, reportedly comes with 4 GB of memory across a 64-bit wide memory bus. The chip also packs a tiny 16 MB Infinity Cache. VideoCardz scored the first renders of the upcoming Radeon RX 6500 XT and RX 6400, which are based on the Navi 24. The RX 6500 XT features a full-height, 2-slot board design that uses a simple aluminium monoblock fan-heatsink. The RX 6400, on the other hand, is not just low-profile (half-height), but also single-slot.
Update Dec 28th: Unless we’re mistaken, the SMDs near the PCIe interface in those renders seem to suggest that the GPU features a PCIe x4 interface. This should offer sufficient bandwidth for a GPU in this segment, and should help lower the pin-count of the GPU, as well as board costs.
