Specification comparison
DDR5 starts at 4800MHz and DDR4 starts at 3200MHz. DDR5 has higher bandwidth but also higher latency. DDR5 has a voltage of 1.1V, while DDR4 has a voltage of 1.2V, which is more energy-efficient.
Actual performance gap
Game frame rate difference: about 5-10% at 1080p, with even smaller difference at 4K (GPU bottleneck). Creative productivity: Increase video rendering, compression, and other multi-core scenes by 15-20%. I hardly feel any difference in daily office work.
Purchase suggestions
New installation: Choose DDR5 platform (AM5/LGA1700), with ample room for future upgrades. Old platform upgrade: There is no need to switch to DDR5, as the platform is incompatible and the cost is too high. Capacity is more important than frequency: 32GB 3200 is more practical than 16GB 6000.
Other Attention
DDR5 requires XMP/EXPO to be enabled in order to run at full frequency. Dual channel is standard, and single channel performance is halved. The heat dissipation vest depends on the requirements, low-end memory is not needed.
