Leaked AMD Navi circuit board fitted with high-end VRM and GDDR6 memory
An AMD PCB claimed to be that of an unreleased AMD Navi graphics card has surfaced on the web. The upcoming graphics card architecture expected to replace Polaris isn’t expected until later in the year - further announcements expected at Computex - but AMD is sure to be finalising designs and ramping up manufacturing right about now if it hopes to launch with significant numbers when that day comes.
The PCB has been snapped entirely in the buff, scooped from a now defunct page on Baidu by serial leaker Komachi_Ensaka. While that means that we have no actual silicon to speculate over, the supposed Navi board’s naked footprint offers us a lot of information regardless.
There are a total of eight memory locations on the board - a pin configuration likely intended for 8GB of GDDR6. There’s potential for more capacity depending on the memory density of the chips AMD decide upon, but 8GBs feels plenty for the mainstream market. Fitted with a 256-bit memory interface and utilising, let’s say, Samsung’s mass-volume GDDR6 8Gb chip at 14Gbps, that would result in a bandwidth of 448GB/s. Just a little shy of double the RX580’s 256GB/s bandwidth.
