Both DDR4 and DDR3 use 64-bit memory controllers on each channel, which results in a 128-bit bus for dual-channel memory and a 256-bit bus for dual-channel memory. Quadrilateral – Channel. On the other hand, both GDDR5 and DDR5 memory use 32-bit controllers. The former can use any number of 32-bit controllers, while the latter has two per DIMM. In cases where the CPU memory configuration has wider but fewer channels, the GPU can support any number of 32-bit memory channels. This is why many high-end Gpus, such as the GeForce RTX 2080 Ti and RTX 2080, have 384-bit and 256-bit bus widths, respectively. Both RTX 20 series cards are connected to 1GB memory chips via 8 (for the 2080) and 12 (for the Ti) 32-bit memory controllers or channels. GDDR5/6 can also work in so-called clamshell mode, where instead of connecting to a single memory chip, each channel is divided into two channels. This also enables manufacturers to double the storage capacity and enables hybrid storage configurations, such as the GTX 660 with a 192-bit bus width.
