Ddr prefetch burst

WebJan 23, 2024 · For DDR4 and GDDR5, each burst was 8 (or 16B). With DDR5 (and GDDR5X/6), it has been increased to as much as 32 (up to 64B). There are two bursts per clock and they happen at the effective data rate. GDDR6, like GDDR5X, has a 16n (BL16) prefetch but it’s divided into two channels. http://monitorinsider.com/GDDR6.html
