AMD Readies Three RX 5500 Series and Two RX 5300 Series SKUs Based on "Navi 14"

A collaborative effort by several Redditors discovered that AMD could carve as many as five Radeon RX 5000-series SKUs based on its upcoming 7 nm "Navi 14" GPU. They poured through thousands of lines of code in AMD's open-source GPU driver files. Among these are two mobile GPUs, and three desktop. The "Navi 14" silicon allegedly features up to 24 RDNA compute units making up 1,536 stream processors; and possibly a 128-bit wide GDDR6 memory interface. The highest trim based on this silicon is the "Navi 14 XTX" variant, which goes by the commercial name Radeon RX 5500 XT. While it remains to be seen if it maxes out all 24 CUs present on the silicon, it certainly has the highest engine gaming clocks at 1717 MHz.

Next up is the Radeon RX 5500 ("Navi 14 XT"). This SKU is popularized in AMD's October 2019 product announcements. It is known to feature 22 compute units working out to 1,408 stream processors, and up to 8 GB of GDDR6 memory across the chip's 128-bit wide memory interface. Its gaming clocks are rated at 1670 MHz. The other popularized SKU is the Radeon RX 5500M ("Navi 14 XTM"). With the same core-config as the RX 5500, this SKU has slightly lesser clock-speeds contributing to a more aggressive power-management. Its gaming clocks are rated at 1448 MHz. It turns out that AMD is interested in carving out a whole different segment of GPUs based on "Navi 14," the Radeon RX 5300 series.
