With the coming of AMD’s Ryzen processors and the MCM design, high-speed DDR4 memory has suddenly become more relevant. Released in 2014, it initially focused on reducing the voltage and power consumption rather than increasing the operating frequencies. In DDR4 memory, two transfers occur per cycle (Double Data Rate) which is why the effective data rate is twice the frequency: 3600MT/s for 1800MHz and 3200MT/s for 1600MHz.ĭDR4 is the latest iteration of DRAM. This isn’t the operating frequency but the number of MT/s (million transfers per sec).
OEMs often advertise DDR4 speeds as DDR4-3200 or DDR4-3600. In this post, we compare DDR3 vs DDR4 vs DDR5 and analyze the difference between the last three generations of DRAM.ĭDR4 runs between 1200 to 1600MHz. It’s successor, DDR5 has been specified, but it’s yet to hit the market. The latest iteration of DRAM is DDR4 memory. It‘s slower than static ram (SRAM) but is much more affordable which is the primary reason for its widespread use. Nearly all kinds of volatile memory is based on dynamic random access memory or DRAM.
