It seems like DDR4 has ruled the roost forever. Finally, new motherboards and architectures have allowed memory to grow wings with the advent of DDR5. Improved clock speeds promise up to twice the bandwidth of DDR4, all with lower voltage for better efficiency. To further help with that last bit, DDR5 has on-board power management to reduce motherboard cost and complexity. This is particularly nice for all-new, powerful laptops and embedded devices.
Reliability has also been improved by the introduction of on-die error-correction technology. Memory availability is improved by splitting the internal 64-bit (72-bit with ECC) channel into two independent, 32-bit channels (40-bit with ECC) and the addition of same bank refresh. Combined with other features, including those that allow for up to four times the module capacity with consumer DRAM, DDR5 ensures your multi-core CPU won’t be memory-starved. You can pack more memory than ever into your portable machine and take it on the go.
