All 5600 XT’s will come with 6GB of GDDR6 memory. The 6GB sits on a 192-bit bus with reference speeds of 1,500 MHz (12 Gbps GDDR6 effective). The clock on the Pulse OC (now 14 Gbps GDDR6 effective) yields 336 GBps of bandwidth. Considering the issues that plagued the 4GB 5500 XTs (
especially on PCIe 3.0 x16), AMD was asked if the company expects any differences if VRAM runs out and they stated they did not expect any due to the full bandwidth of the slot (PCIe 4.0 x16 for 5600 XT) along with the increased bandwidth in general.
