The prices of AMD Ryzen 5000 are already high and now leaked slide revealed that next-Generation processors also require faster memory, because Zen3 architecture will feature 1:1:1 ratio for each clock speeds and user will need atleast DDR4 @4000MHz. The alleged slide also explains that DDR4-4000 memory is to Zen3 (Ryzen 5000) processor what DDR4-3800 was to Zen2 (Ryzen 3000 series). So, to take advantage of the maximum potential of the system, it is recommended to acquire faster memories.

To get an idea, the cheapest memory on the market at that speed are T-Force XCalibur RGB, where for 16 GB DDR4 @ 4000 MHz we will have to pay 138.99 euros. The cheapest Thermaltake memories in that configuration are worth 159 euros and the cheapest HyperX Predators are 190.97 euros. If we want 32 GB, the cheapest kit is a G.Skill Trident Z RGB for 340 euros .

On the other hand, the differences between the three integrated memory clocks are indicated below:

  • Infinity Fabric Clock (fclk): Manages how quickly the CPU cores can communicate across the CPU dies and with the SoC controller (e.g. PCIe, SATA, USB)
  • Memory Controller Clock (uclk): Manages how quickly the memory controller can ingest / extract commands from RAM
  • Memory Clock (mclk): The memory frequency of your main system
